Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.. Adverse Reactions in AdultsThe data described herein reflect exposure to REMICADE in 4779 adult patients (1304 patients with RA, 1106 patients with CD, 202 with AS, 293 with PsA, 484 with UC, 1373 with Ps, and 17 patients with other conditions), including 2625 patients exposed beyond 30 weeks and 374 exposed beyond year. [For information on adverse reactions in pediatric patients see Adverse Reactions (6.1)]. One of the most-common reasons for discontinuation of treatment was infusion-related reactions (e.g., dyspnea, flushing, headache and rash).. Infusion-Related Reactions. Adverse Reactions During or Shortly After InfusionAn infusion reaction was defined in clinical trials as any adverse event occurring during an infusion or within hour after an infusion. In all the clinical studies, approximately 20% of REMICADE-treated patients experienced an infusion reaction compared with 10% of placebo-treated patients. Of REMICADE-treated patients who had an infusion reaction during the induction period, 27% experienced an infusion reaction during the maintenance period. Of patients who did not have an infusion reaction during the induction period, 9% experienced an infusion reaction during the maintenance period.Among all REMICADE infusions, 3% were accompanied by nonspecific symptoms such as fever or chills, 1% were accompanied by cardiopulmonary reactions (primarily chest pain, hypotension, hypertension or dyspnea), and <1% were accompanied by pruritus, urticaria, or the combined symptoms of pruritus/urticaria and cardiopulmonary reactions. Serious infusion reactions occurred in <1% of patients and included anaphylaxis, convulsions, erythematous rash and hypotension. Approximately 3% of patients discontinued REMICADE because of infusion reactions, and all patients recovered with treatment and/or discontinuation of the infusion. REMICADE infusions beyond the initial infusion were not associated with higher incidence of reactions. The infusion reaction rates remained stable in Ps through year in Ps Study I. In psoriasis Study II, the rates were variable over time and somewhat higher following the final infusion than after the initial infusion. Across the Ps studies, the percent of total infusions resulting in infusion reactions (i.e., an adverse event occurring within hour) was 7% in the mg/kg group, 4% in the mg/kg group, and 1% in the placebo group.Patients who became positive for antibodies to infliximab were more likely (approximately two-to three-fold) to have an infusion reaction than were those who were negative. Use of concomitant immunosuppressant agents appeared to reduce the frequency of both antibodies to infliximab and infusion reactions [see Adverse Reactions (6.2) and Drug Interactions (7.3)].. Infusion Reactions Following Re-administrationIn clinical trial of patients with moderate to severe Ps designed to assess the efficacy of long-term maintenance therapy versus re-treatment with an induction regimen of REMICADE following disease flare, 4% (8/219) of patients in the re-treatment induction therapy arm experienced serious infusion reactions versus <1% (1/222) in the maintenance therapy arm. Patients enrolled in this trial did not receive any concomitant immunosuppressant therapy. In this study, the majority of serious infusion reactions occurred during the second infusion at Week 2. Symptoms included, but were not limited to, dyspnea, urticaria, facial edema, and hypotension. In all cases, REMICADE treatment was discontinued and/or other treatment instituted with complete resolution of signs and symptoms.. Delayed Reactions/Reactions Following Re-administrationIn Ps studies, approximately 1% of REMICADE-treated patients experienced possible delayed hypersensitivity reaction, generally reported as serum sickness or combination of arthralgia and/or myalgia with fever and/or rash. These reactions generally occurred within weeks after repeat infusion.. InfectionsIn REMICADE clinical studies, treated infections were reported in 36% of REMICADE-treated patients (average of 51 weeks of follow-up) and in 25% of placebo-treated patients (average of 37 weeks of follow-up). The infections most frequently reported were respiratory tract infections (including sinusitis, pharyngitis, and bronchitis) and urinary tract infections. Among REMICADE-treated patients, serious infections included pneumonia, cellulitis, abscess, skin ulceration, sepsis, and bacterial infection. In clinical trials, opportunistic infections were reported; cases each of coccidioidomycosis (1 case was fatal) and histoplasmosis (1 case was fatal), and case each of pneumocystosis, nocardiosis and cytomegalovirus. Tuberculosis (TB) was reported in 14 patients, of whom died due to miliary tuberculosis. Other cases of TB, including disseminated TB, also have been reported post-marketing. Most of these cases of TB occurred within the first months after initiation of therapy with REMICADE and may reflect recrudescence of latent disease [see Warnings and Precautions (5.1)]. In the 1-year placebo-controlled studies RA and RA II, 5.3% of patients receiving REMICADE every weeks with MTX developed serious infections as compared to 3.4% of placebo patients receiving MTX. Of 924 patients receiving REMICADE, 1.7% developed pneumonia and 0.4% developed TB, when compared to 0.3% and 0.0% in the placebo arm respectively. In shorter (22-week) placebo-controlled study of 1082 RA patients randomized to receive placebo, mg/kg or 10 mg/kg REMICADE infusions at 0, 2, and weeks, followed by every weeks with MTX, serious infections were more frequent in the 10 mg/kg REMICADE group (5.3%) than the mg/kg or placebo groups (1.7% in both). During the 54-week Crohns II Study, 15% of patients with fistulizing CD developed new fistula-related abscess.In REMICADE clinical studies in patients with UC, infections treated with antimicrobials were reported in 27% of REMICADE-treated patients (average of 41 weeks of follow-up) and in 18% of placebo-treated patients (average 32 weeks of follow-up). The types of infections, including serious infections, reported in patients with UC were similar to those reported in other clinical studies. The onset of serious infections may be preceded by constitutional symptoms such as fever, chills, weight loss, and fatigue. The majority of serious infections, however, may also be preceded by signs or symptoms localized to the site of the infection.. Autoantibodies/Lupus-like SyndromeApproximately half of REMICADE-treated patients in clinical trials who were antinuclear antibody (ANA) negative at baseline developed positive ANA during the trial compared with approximately one-fifth of placebo-treated patients. Anti-dsDNA antibodies were newly detected in approximately one-fifth of REMICADE-treated patients compared with 0% of placebo-treated patients. Reports of lupus and lupus-like syndromes, however, remain uncommon.. MalignanciesIn controlled trials, more REMICADE-treated patients developed malignancies than placebo-treated patients [see Warnings and Precautions (5.2)].In randomized controlled clinical trial exploring the use of REMICADE in patients with moderate to severe COPD who were either current smokers or ex-smokers, 157 patients were treated with REMICADE at doses similar to those used in RA and CD. Of these REMICADE-treated patients, developed malignancy, including lymphoma, for rate of 7.67 cases per 100 patient-years of follow-up (median duration of follow-up 0.8 years; 95% CI 3.51 14.56). There was reported malignancy among 77 control patients for rate of 1.63 cases per 100 patient-years of follow-up (median duration of follow-up 0.8 years; 95% CI 0.04 9.10). The majority of the malignancies developed in the lung or head and neck [see Warnings and Precautions (5.2)].. Adverse Reactions in Patients with NYHA Class III/IV Heart FailureIn randomized, double-blind study evaluating REMICADE in moderate or severe heart failure (NYHA Class III/IV; left ventricular ejection fraction <=35%), 150 patients were randomized to receive treatment with infusions of REMICADE 10 mg/kg, mg/kg, or placebo, at 0, 2, and weeks. Higher incidences of mortality and hospitalization due to worsening heart failure were observed in patients receiving the 10 mg/kg REMICADE dose. At year, patients in the 10 mg/kg REMICADE group had died compared with deaths each in the mg/kg REMICADE and the placebo groups. There were trends toward increased dyspnea, hypotension, angina, and dizziness in both the 10 mg/kg and mg/kg REMICADE treatment groups, versus placebo. REMICADE has not been studied in patients with mild heart failure (NYHA Class I/II) [see Contraindications (4) and Warnings and Precautions (5.5)]. HepatotoxicitySevere liver injury, including acute liver failure and autoimmune hepatitis, has been reported in patients receiving REMICADE [see Warnings and Precautions (5.4)]. Reactivation of hepatitis virus has occurred in patients receiving TNF blockers, including REMICADE, who are chronic carriers of this virus [see Warnings and Precautions (5.3)].In clinical trials in RA, CD, UC, AS, Ps, and PsA, elevations of aminotransferases were observed (ALT more common than AST) in greater proportion of patients receiving REMICADE than in controls (Table 1), both when REMICADE was given as monotherapy and when it was used in combination with other immunosuppressive agents. In general, patients who developed ALT and AST elevations were asymptomatic, and the abnormalities decreased or resolved with either continuation or discontinuation of REMICADE, or modification of concomitant medications.

Adverse Reactions in Psoriasis StudiesDuring the placebo-controlled portion across the clinical trials up to Week 16, the proportion of patients who experienced at least serious adverse reaction (SAE; defined as resulting in death, life threatening, requires hospitalization, or persistent or significant disability/incapacity) was 0.5% in the mg/kg REMICADE group, 1.9% in the placebo group, and 1.6% in the mg/kg REMICADE group. Among patients in the Phase studies, 12.4% of patients receiving REMICADE mg/kg every weeks through year of maintenance treatment experienced at least SAE in Study I. In Study II, 4.1% and 4.7% of patients receiving REMICADE mg/kg and mg/kg every weeks, respectively, through year of maintenance treatment experienced at least SAE.One death due to bacterial sepsis occurred 25 days after the second infusion of mg/kg REMICADE. Serious infections included sepsis, and abscesses. In Study I, 2.7% of patients receiving REMICADE mg/kg every weeks through year of maintenance treatment experienced at least serious infection. In Study II, 1.0% and 1.3% of patients receiving REMICADE mg/kg and mg/kg, respectively, through year of treatment experienced at least serious infection. The most common serious infection (requiring hospitalization) was abscess (skin, throat, and peri-rectal) reported by (0.7%) patients in the mg/kg REMICADE group. Two active cases of tuberculosis were reported: weeks and 34 weeks after starting REMICADE. In the placebo-controlled portion of the Ps studies, of 1123 patients who received REMICADE at any dose were diagnosed with at least one NMSC compared to of 334 patients who received placebo. In the Ps studies, 1% (15/1373) of patients experienced serum sickness or combination of arthralgia and/or myalgia with fever, and/or rash, usually early in the treatment course. Of these patients, required hospitalization due to fever, severe myalgia, arthralgia, swollen joints, and immobility. Other Adverse Reactions in AdultsSafety data are available from 4779 REMICADE-treated adult patients, including 1304 with RA, 1106 with CD, 484 with UC, 202 with AS, 293 with PsA, 1373 with Ps and 17 with other conditions. [For information on other adverse reactions in pediatric patients, see Adverse Reactions (6.1) ]. Adverse reactions reported in >=5% of all patients with RA receiving or more infusions are in Table 2. The types and frequencies of adverse reactions observed were similar in REMICADE-treated RA, AS, PsA, Ps, and CD patients except for abdominal pain, which occurred in 26% of REMICADE-treated patients with CD. In the CD studies, there were insufficient numbers and duration of follow-up for patients who never received REMICADE to provide meaningful comparisons.Table 2:Adverse Reactions that Occurred in >= 5% of Patients who Received >= REMICADE Infusions for RAPlaceboREMICADE(n=350)(n=1129)Average weeks of follow-up59 weeks66 weeksUpper respiratory tract infection25%32%Nausea20%21%Headache14%18%Sinusitis8%14%Diarrhea12%12%Abdominal pain8%12%Pharyngitis8%12%Coughing 8%12%Bronchitis 9%10%Rash5%10%Dyspepsia7%10%Fatigue7%9%Urinary tract infection6%8%Pain7%8%Arthralgia7%8%Pruritus2%7%Fever4%7%Hypertension5%7%Moniliasis3%5%The most common serious adverse reactions observed in clinical trials were infections [see Adverse Reactions (6.1)].

White Cell and Reticuloendothelial: leukopenia, lymphadenopathy. Adverse Reactions in Pediatric Patients. Adverse Reactions in Pediatric Patients with Crohns DiseaseThere were some differences in the adverse reactions observed in the pediatric patients receiving REMICADE compared to those observed in adults with CD. These differences are discussed in the following paragraphs.The following adverse reactions were reported more commonly in 103 randomized pediatric CD patients administered mg/kg REMICADE through 54 weeks than in 385 adult CD patients receiving similar treatment regimen: anemia (11%), leukopenia (9%), flushing (9%), viral infection (8%), neutropenia (7%), bone fracture (7%), bacterial infection (6%), and respiratory tract allergic reaction (6%). Infections were reported in 56% of randomized pediatric patients in Study Peds Crohns and in 50% of adult patients in Study Crohns I. In Study Peds Crohns, infections were reported more frequently for patients who received every 8-week as opposed to every 12-week infusions (74% and 38%, respectively), while serious infections were reported for patients in the every 8-week and patients in the every 12-week maintenance treatment group. The most commonly reported infections were upper respiratory tract infection and pharyngitis, and the most commonly reported serious infection was abscess. Pneumonia was reported for patients, (2 in the every 8-week and in the every 12-week maintenance treatment groups). Herpes zoster was reported for patients in the every 8-week maintenance treatment group.In Study Peds Crohns, 18% of randomized patients experienced or more infusion reactions, with no notable difference between treatment groups. Of the 112 patients in Study Peds Crohns, there were no serious infusion reactions, and patients had non-serious anaphylactoid reactions.Elevations of ALT up to times the upper limit of normal (ULN) were seen in 18% of pediatric patients in CD clinical trials; 4% had ALT elevations >=3 ULN, and 1% had elevations >=5 ULN. (Median follow-up was 53 weeks).. Adverse Reactions in Pediatric Patients with Ulcerative ColitisOverall, the adverse reactions reported in the pediatric UC trial and adult UC (Study UC and Study UC II) studies were generally consistent. In pediatric UC trial, the most common adverse reactions were upper respiratory tract infection, pharyngitis, abdominal pain, fever, and headache.Infections were reported in 31 (52%) of 60 treated patients in the pediatric UC trial and 22 (37%) required oral or parenteral antimicrobial treatment. The proportion of patients with infections in the pediatric UC trial was similar to that in the pediatric CD study (Study Peds Crohns) but higher than the proportion in the adults UC studies (Study UC and Study UC II). The overall incidence of infections in the pediatric UC trial was 13/22 (59%) in the every week maintenance treatment group. Upper respiratory tract infection (7/60 [12%]) and pharyngitis (5/60 [8%]) were the most frequently reported respiratory system infections. Serious infections were reported in 12% (7/60) of all treated patients. Elevations of ALT up to times the upper limit of normal (ULN) were seen in 17% (10/60) of pediatric patients in the pediatric UC trial; 7% (4/60) had ALT elevations >=3 ULN, and 2% (1/60) had elevations >=5 ULN (median follow-up was 49 weeks). Overall, of 60 (13%) treated patients experienced one or more infusion reactions, including of 22 (18%) patients in the every 8-week treatment maintenance group. No serious infusion reactions were reported. In the pediatric UC trial, 45 patients were in the 12 to 17 year age group and 15 in the to 11 year age group. The numbers of patients in each subgroup are too small to make any definitive conclusions about the effect of age on safety events. There were higher proportions of patients with serious adverse events (40% vs. 18%) and discontinuation due to adverse events (40% vs. 16%) in the younger age group than in the older age group. While the proportion of patients with infections was also higher in the younger age group (60% vs. 49%), for serious infections, the proportions were similar in the two age groups (13% in the to 11 year age group vs. 11% in the 12 to 17 year age group). Overall proportions of adverse reactions, including infusion reactions, were similar between the to 11 and 12 to 17 year age groups (13%).. 6.2Immunogenicity. As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other infliximab products may be misleading.Treatment with REMICADE can be associated with the development of antibodies to infliximab. An enzyme immunoassay (EIA) method was originally used to measure anti-infliximab antibodies in clinical studies of REMICADE. The EIA method is subject to interference by serum infliximab, possibly resulting in an underestimation of the rate of patient antibody formation. separate, drug-tolerant electrochemiluminescence immunoassay (ECLIA) method for detecting antibodies to infliximab was subsequently developed and validated. This method is 60-fold more sensitive than the original EIA. With the ECLIA method, all clinical samples can be classified as either positive or negative for antibodies to infliximab without the need for the inconclusive category.The incidence of antibodies to infliximab was based on the original EIA method in all clinical studies of REMICADE except for the Phase study in pediatric patients with UC where the incidence of antibodies to infliximab was detected using both the EIA and ECLIA methods.. Immunogenicity in Adult PatientsThe incidence of antibodies to infliximab in patients with RA and CD given 3-dose induction regimen followed by maintenance dosing was approximately 10% as assessed through to years of REMICADE treatment. higher incidence of antibodies to infliximab was observed in CD patients receiving REMICADE after drug-free intervals >16 weeks. In PsA study in which 191 patients received mg/kg with or without MTX, antibodies to infliximab occurred in 15% of patients. The majority of antibody-positive patients had low titers. Antibody development was lower among RA and CD patients receiving immunosuppressant therapies such as 6-MP/AZA or MTX. Patients who were antibody-positive were more likely to have higher rates of clearance, have reduced efficacy, and to experience an infusion reaction than were patients who were antibody negative [see Adverse Reactions (6.1)]. In the Ps Study II, which included both the mg/kg and mg/kg doses, antibodies were observed in 36% of patients treated with mg/kg every weeks for year, and in 51% of patients treated with mg/kg every weeks for year.In the Ps Study III, which also included both the mg/kg and mg/kg doses, antibodies were observed in 20% of patients treated with mg/kg induction (weeks 0, and 6), and in 27% of patients treated with mg/kg induction. Despite the increase in antibody formation, the infusion reaction rates in Studies and II in patients treated with mg/kg induction followed by every week maintenance for year and in Study III in patients treated with mg/kg induction (14.1%-23.0%) and serious infusion reaction rates (<1%) were similar to those observed in other study populations. The clinical significance of apparent increased immunogenicity on efficacy and infusion reactions in Ps patients as compared to patients with other diseases treated with REMICADE over the long term is not known.. Immunogenicity in Pediatric Patients with Crohns DiseaseIn Study Peds Crohns, in which all patients received stable doses of 6-MP, AZA, or MTX, excluding inconclusive samples, of 24 patients had antibodies to infliximab. Although 105 patients were tested for antibodies to infliximab, 81 patients were classified as inconclusive because they could not be ruled as negative due to assay interference by the presence of infliximab in the sample.. Immunogenicity in Pediatric Patients with Ulcerative ColitisIn the pediatric UC trial, 58 patients were evaluated for antibodies to infliximab using the EIA as well as the drug-tolerant ECLIA. With the EIA, of 58 (7%) patients had antibodies to infliximab. With the ECLIA, 30 of 58 (52%) patients had antibodies to infliximab. The higher incidence of antibodies to infliximab by the ECLIA method was due to the 60-fold higher sensitivity compared to the EIA method. While EIA-positive patients generally had undetectable trough infliximab concentrations, ECLIA-positive patients could have detectable trough concentrations of infliximab because the ECLIA assay is more sensitive and drug-tolerant.. 6.3 Postmarketing Experience. Adverse reactions, some with fatal outcomes, have been identified during post approval use of REMICADE in adult and pediatric patients. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.. Postmarketing Adverse Reactions in Adults and Pediatric PatientsNeutropenia [see Warnings and Precautions (5.6)], agranulocytosis (including infants exposed in utero to infliximab), idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura.Interstitial lung disease (including pulmonary fibrosis/interstitial pneumonitis and rapidly progressive disease).Pericardial effusion, systemic and cutaneous vasculitis.Erythema multiforme, Stevens-Johnson Syndrome, toxic epidermal necrolysis, linear IgA bullous dermatosis (LABD), acute generalized exanthematous pustulosis (AGEP), new onset and worsening psoriasis (all subtypes including pustular, primarily palmoplantar), lichenoid reactions.Peripheral demyelinating disorders (such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy) transverse myelitis, and neuropathies (additional neurologic reactions have also been observed) [see Warnings and Precautions (5.9)].Acute liver failure, jaundice, hepatitis, and cholestasis [see Warnings and Precautions (5.4)].Serious infections [see Warnings and Precautions (5.1)] and vaccine breakthrough infection including bovine tuberculosis (disseminated BCG infection) following vaccination in an infant exposed in utero to infliximab [see Warnings and Precautions (5.13)].

CLINICAL STUDIES SECTION.

14CLINICAL STUDIES. 14.1Adult Crohns Disease. Active Crohns Disease in AdultsThe safety and efficacy of single and multiple doses of REMICADE were assessed in randomized, double-blind, placebo-controlled clinical studies in 653 adult patients with moderate to severely active CD [Crohns Disease Activity Index (CDAI) >=220 and <=400] with an inadequate response to prior conventional therapies. Concomitant stable doses of aminosalicylates, corticosteroids and/or immunomodulatory agents were permitted and 92% of patients continued to receive at least one of these medications.In the single-dose trial of 108 adult patients, 16% (4/25) of placebo patients achieved clinical response (decrease in CDAI >=70 points) at Week vs. 81% (22/27) of patients receiving mg/kg REMICADE (p<0.001, two-sided, Fishers Exact test). Additionally, 4% (1/25) of placebo patients and 48% (13/27) of patients receiving mg/kg REMICADE achieved clinical remission (CDAI<150) at Week 4.In multidose trial (ACCENT [Study Crohns I]), 545 adult patients received mg/kg at Week and were then randomized to one of three treatment groups; the placebo maintenance group received placebo at Weeks and 6, and then every weeks; the mg/kg maintenance group received mg/kg at Weeks and 6, and then every weeks; and the 10 mg/kg maintenance group received mg/kg at Weeks and 6, and then 10 mg/kg every weeks. Patients in response at Week were randomized and analyzed separately from those not in response at Week 2. Corticosteroid taper was permitted after Week 6.At Week 2, 57% (311/545) of patients were in clinical response. At Week 30, significantly greater proportion of these patients in the mg/kg and 10 mg/kg maintenance groups achieved clinical remission compared to patients in the placebo maintenance group (Table 3).Additionally, significantly greater proportion of patients in the mg/kg and 10 mg/kg REMICADE maintenance groups were in clinical remission and were able to discontinue corticosteroid use compared to patients in the placebo maintenance group at Week 54 (Table 3).Table 3:Clinical Remission and Steroid Withdrawal in Adult Patients with CD (Study Crohns I)Single 5-mg/kg DoseREMICADE at Week Three-Dose InductionREMICADE mg/kg administered at Weeks 0, and Placebo Maintenance REMICADE Maintenanceq8 wks mg/kg10 mg/kgWeek 3025/10241/10448/105 Clinical remission25%39%46% P-valueP-values represent pairwise comparisons to placebo 0.0220.001Week 546/5414/5618/53 Patients in remission able to discontinue corticosteroid useOf those receiving corticosteroids at baseline 11%25%34% P-value 0.0590.005Patients in the REMICADE maintenance groups (5 mg/kg and 10 mg/kg) had longer time to loss of response than patients in the placebo maintenance group (Figure 1). At Weeks 30 and 54, significant improvement from baseline was seen among the mg/kg and 10 mg/kg REMICADE-treated groups compared to the placebo group in the disease-specific inflammatory bowel disease questionnaire (IBDQ), particularly the bowel and systemic components, and in the physical component summary score of the general health-related quality of life questionnaire SF-36.Figure 1:Kaplan-Meier Estimate of the Proportion of Adults with CD Who Had Not Lost Response Through Week 54 (Study Crohns I)In subset of 78 patients who had mucosal ulceration at baseline and who participated in an endoscopic substudy, 13 of 43 patients in the REMICADE maintenance group had endoscopic evidence of mucosal healing compared to of 28 patients in the placebo group at Week 10. Of the REMICADE-treated patients showing mucosal healing at Week 10, of 12 patients also showed mucosal healing at Week 54.Patients who achieved response and subsequently lost response were eligible to receive REMICADE on an episodic basis at dose that was mg/kg higher than the dose to which they were randomized. The majority of such patients responded to the higher dose. Among patients who were not in response at Week 2, 59% (92/157) of REMICADE maintenance patients responded by Week 14 compared to 51% (39/77) of placebo maintenance patients. Among patients who did not respond by Week 14, additional therapy did not result in significantly more responses [see Dosage and Administration (2)].. Figure 1. Fistulizing Crohns Disease in AdultsThe safety and efficacy of REMICADE were assessed in randomized, double-blind, placebo-controlled studies in adult patients with fistulizing CD with fistula(s) that were of at least months duration. Concurrent use of stable doses of corticosteroids, 5-aminosalicylates, antibiotics, MTX, 6-mercaptopurine (6-MP) and/or azathioprine (AZA) was permitted.In the first trial, 94 adult patients received doses of either placebo or REMICADE at Weeks 0, and 6. Fistula response (>=50% reduction in number of enterocutaneous fistulas draining upon gentle compression on at least consecutive visits without an increase in medication or surgery for CD) was seen in 68% (21/31) of patients in the mg/kg REMICADE group (P=0.002) and 56% (18/32) of patients in the 10 mg/kg REMICADE group (P=0.021) vs. 26% (8/31) of patients in the placebo arm. The median time to onset of response and median duration of response in REMICADE-treated patients was and 12 weeks, respectively. Closure of all fistulas was achieved in 52% of REMICADE-treated patients compared with 13% of placebo-treated patients (P<0.001).In the second trial (ACCENT II [Study Crohns II]), adult patients who were enrolled had to have at least draining enterocutaneous (perianal, abdominal) fistula. All patients received mg/kg REMICADE at Weeks 0, and 6. Patients were randomized to placebo or mg/kg REMICADE maintenance at Week 14. Patients received maintenance doses at Week 14 and then every weeks through Week 46. Patients who were in fistula response (fistula response was defined the same as in the first trial) at both Weeks 10 and 14 were randomized separately from those not in response. The primary endpoint was time from randomization to loss of response among those patients who were in fistula response.Among the randomized patients (273 of the 296 initially enrolled), 87% had perianal fistulas and 14% had abdominal fistulas. Eight percent also had rectovaginal fistulas. Greater than 90% of the patients had received previous immunosuppressive and antibiotic therapy.At Week 14, 65% (177/273) of patients were in fistula response. Patients randomized to REMICADE maintenance had longer time to loss of fistula response compared to the placebo maintenance group (Figure 2). At Week 54, 38% (33/87) of REMICADE-treated patients had no draining fistulas compared with 22% (20/90) of placebo-treated patients (P=0.02). Compared to placebo maintenance, patients on REMICADE maintenance had trend toward fewer hospitalizations.Figure 2: Life Table Estimates of the Proportion of Adult CD Patients Who Had Not Lost Fistula Response Through Week 54 (Study Crohns II)Patients who achieved fistula response and subsequently lost response were eligible to receive REMICADE maintenance therapy at dose that was mg/kg higher than the dose to which they were randomized. Of the placebo maintenance patients, 66% (25/38) responded to mg/kg REMICADE, and 57% (12/21) of REMICADE maintenance patients responded to 10 mg/kg.Patients who had not achieved response by Week 14 were unlikely to respond to additional doses of REMICADE.Similar proportions of patients in either group developed new fistulas (17% overall) and similar numbers developed abscesses (15% overall).. Figure 2. 14.2Pediatric Crohns Disease. The safety and efficacy of REMICADE were assessed in randomized, open-label study (Study Peds Crohns) in 112 pediatric patients aged to 17 years old with moderately to severely active CD and an inadequate response to conventional therapies. The median age was 13 years and the median Pediatric Crohns Disease Activity Index (PCDAI) was 40 (on scale of to 100). All patients were required to be on stable dose of 6-MP, AZA, or MTX; 35% were also receiving corticosteroids at baseline.All patients received induction dosing of mg/kg REMICADE at Weeks 0, 2, and 6. At Week 10, 103 patients were randomized to maintenance regimen of mg/kg REMICADE given either every weeks or every 12 weeks. At Week 10, 88% of patients were in clinical response (defined as decrease from baseline in the PCDAI score of >=15 points and total PCDAI score of <=30 points), and 59% were in clinical remission (defined as PCDAI score of <=10 points).The proportion of pediatric patients achieving clinical response at Week 10 compared favorably with the proportion of adults achieving clinical response in Study Crohns I. The study definition of clinical response in Study Peds Crohns was based on the PCDAI score, whereas the CDAI score was used in the adult Study Crohns I.At both Week 30 and Week 54, the proportion of patients in clinical response was greater in the every 8-week treatment group than in the every 12-week treatment group (73% vs. 47% at Week 30, and 64% vs. 33% at Week 54). At both Week 30 and Week 54, the proportion of patients in clinical remission was also greater in the every 8-week treatment group than in the every 12-week treatment group (60% vs. 35% at Week 30, and 56% vs. 24% at Week 54), (Table 4).For patients in Study Peds Crohns receiving corticosteroids at baseline, the proportion of patients able to discontinue corticosteroids while in remission at Week 30 was 46% for the every 8-week maintenance group and 33% for the every 12-week maintenance group. At Week 54, the proportion of patients able to discontinue corticosteroids while in remission was 46% for the every 8-week maintenance group and 17% for the every 12-week maintenance group.Table 4:Response and Remission in Study Peds Crohns5 mg/kg REMICADEEvery WeekEvery 12 WeekTreatment GroupTreatment GroupPatients randomized5251Clinical ResponseDefined as decrease from baseline in the PCDAI score of >=15 points and total score of <=30 points.

The safety and efficacy of REMICADE were assessed in randomized, double-blind, placebo-controlled clinical studies in 728 adult patients with moderately to severely active UC (Mayo score to 12 [of possible range to 12], Endoscopy subscore >=2) with an inadequate response to conventional oral therapies (Studies UC and UC II). Concomitant treatment with stable doses of aminosalicylates, corticosteroids and/or immunomodulatory agents was permitted. Corticosteroid taper was permitted after Week 8. Patients were randomized at week to receive either placebo, mg/kg REMICADE or 10 mg/kg REMICADE at Weeks 0, 2, 6, and every weeks thereafter through Week 46 in Study UC I, and at Weeks 0, 2, 6, and every weeks thereafter through Week 22 in Study UC II. In Study UC II, patients were allowed to continue blinded therapy to Week 46 at the investigators discretion.Adult patients in Study UC had failed to respond or were intolerant to oral corticosteroids, 6-MP, or AZA. Adult patients in Study UC II had failed to respond or were intolerant to the above treatments and/or aminosalicylates. Similar proportions of patients in Studies UC and UC II were receiving corticosteroids (61% and 51%, respectively), 6-MP/AZA (49% and 43%) and aminosalicylates (70% and 75%) at baseline. More patients in Study UC II than UC were taking solely aminosalicylates for UC (26% vs. 11%, respectively). Clinical response was defined as decrease from baseline in the Mayo score by >=30% and >=3 points, accompanied by decrease in the rectal bleeding subscore of >=1 or rectal bleeding subscore of or 1. Clinical Response, Clinical Remission, and Mucosal HealingIn both Study UC and Study UC II, greater percentages of patients in both REMICADE groups achieved clinical response, clinical remission and mucosal healing than in the placebo group. Each of these effects was maintained through the end of each trial (Week 54 in Study UC I, and Week 30 in Study UC II). In addition, greater proportion of patients in REMICADE groups demonstrated sustained response and sustained remission than in the placebo groups (Table 5).Of patients on corticosteroids at baseline, greater proportions of adult patients in the REMICADE treatment groups were in clinical remission and able to discontinue corticosteroids at Week 30 compared with the patients in the placebo treatment groups (22% in REMICADE treatment groups vs. 10% in placebo group in Study UC I; 23% in REMICADE treatment groups vs. 3% in placebo group in Study UC II). In Study UC I, this effect was maintained through Week 54 (21% in REMICADE treatment groups vs. 9% in placebo group). The REMICADE-associated response was generally similar in the mg/kg and 10 mg/kg dose groups.Table 5: Response, Remission and Mucosal Healing in Adult UC Studies (Studies UC and UC II)Study UC IStudy UC IIPlacebo mg/kg REMICADE10 mg/kg REMICADEPlacebo mg/kg REMICADE10 mg/kg REMICADEPatients randomized121121122123121120Clinical ResponseDefined as decrease from baseline in the Mayo score by >=30% and >=3 points, accompanied by decrease in the rectal bleeding subscore of >=1 or rectal bleeding subscore of or 1.

The safety and effectiveness of REMICADE for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients aged years and older with moderately to severely active UC who have had an inadequate response to conventional therapy are supported by evidence from adequate and well-controlled studies of REMICADE in adults. Additional safety and pharmacokinetic data were collected in an open-label pediatric UC trial in 60 pediatric patients aged through 17 years (median age 14.5 years) with moderately to severely active UC (Mayo score of to 12; Endoscopic subscore >=2) and an inadequate response to conventional therapies. At baseline, the median Mayo score was 8, 53% of patients were receiving immunomodulator therapy (6-MP/AZA/MTX), and 62% of patients were receiving corticosteroids (median dose 0.5 mg/kg/day in prednisone equivalents). Discontinuation of immunomodulators and corticosteroid taper were permitted after Week 0.All patients received induction dosing of mg/kg REMICADE at Weeks 0, 2, and 6. Patients who did not respond to REMICADE at Week received no further REMICADE and returned for safety follow-up. At Week 8, 45 patients were randomized to maintenance regimen of mg/kg REMICADE given either every weeks through Week 46 or every 12 weeks through Week 42. Patients were allowed to change to higher dose and/or more frequent administration schedule if they experienced loss of response.Clinical response at Week was defined as decrease from baseline in the Mayo score by >=30% and >=3 points, including decrease in the rectal bleeding subscore by >=1 points or achievement of rectal bleeding subscore of or 1.Clinical remission at Week was measured by the Mayo score, defined as Mayo score of <=2 points with no individual subscore >1. Clinical remission was also assessed at Week and Week 54 using the Pediatric Ulcerative Colitis Activity Index (PUCAI)1 score and was defined by PUCAI score of <10 points.Endoscopies were performed at baseline and at Week 8. Mayo endoscopy subscore of indicated normal or inactive disease and subscore of indicated mild disease (erythema, decreased vascular pattern, or mild friability).Of the 60 patients treated, 44 were in clinical response at Week 8. Of 32 patients taking concomitant immunomodulators at baseline, 23 achieved clinical response at Week 8, compared to 21 of 28 of those not taking concomitant immunomodulators at baseline. At Week 8, 24 of 60 patients were in clinical remission as measured by the Mayo score and 17 of 51 patients were in remission as measured by the PUCAI score. At Week 54, of 21 patients in the every 8-week maintenance group and of 22 patients in the every 12-week maintenance group achieved remission as measured by the PUCAI score. During maintenance phase, 23 of 45 randomized patients (9 in the every 8-week group and 14 in the every 12-week group) required an increase in their dose and/or increase in frequency of REMICADE administration due to loss of response. Nine of the 23 patients who required change in dose had achieved remission at Week 54. Seven of those patients received the 10 mg/kg every 8-week dosing.. 14.5Rheumatoid Arthritis. The safety and efficacy of REMICADE in adult patients with RA were assessed in multicenter, randomized, double-blind, pivotal trials: ATTRACT (Study RA I) and ASPIRE (Study RA II). Concurrent use of stable doses of folic acid, oral corticosteroids (<=10 mg/day) and/or non-steroidal anti-inflammatory drugs (NSAIDs) was permitted.Study RA was placebo-controlled study of 428 patients with active RA despite treatment with MTX. Patients enrolled had median age of 54 years, median disease duration of 8.4 years, median swollen and tender joint count of 20 and 31 respectively, and were on median dose of 15 mg/wk of MTX. Patients received either placebo+MTX or one of doses/schedules of REMICADE+MTX: mg/kg or 10 mg/kg of REMICADE by IV infusion at Weeks 0, and followed by additional infusions every or weeks in combination with MTX.Study RA II was placebo-controlled study of active treatment arms in 1004 MTX naive patients of or fewer years duration active RA. Patients enrolled had median age of 51 years with median disease duration of 0.6 years, median swollen and tender joint count of 19 and 31 respectively, and >80% of patients had baseline joint erosions. At randomization, all patients received MTX (optimized to 20 mg/wk by Week 8) and either placebo, mg/kg or mg/kg REMICADE at Weeks 0, 2, and and every weeks thereafter.Data on use of REMICADE without concurrent MTX are limited [see Adverse Reactions (6.1)].. Clinical ResponseIn Study RA I, all doses/schedules of REMICADE+MTX resulted in improvement in signs and symptoms as measured by the American College of Rheumatology response criteria (ACR 20) with higher percentage of patients achieving an ACR 20, 50 and 70 compared to placebo+MTX (Table 7). This improvement was observed at Week and maintained through Week 102. Greater effects on each component of the ACR 20 were observed in all patients treated with REMICADE+MTX compared to placebo+MTX (Table 8). More patients treated with REMICADE reached major clinical response than placebo-treated patients (Table 7).In Study RA II, after 54 weeks of treatment, both doses of REMICADE+MTX resulted in statistically significantly greater response in signs and symptoms compared to MTX alone as measured by the proportion of patients achieving ACR 20, 50 and 70 responses (Table 7). More patients treated with REMICADE reached major clinical response than placebo-treated patients (Table 7).Table 7: ACR Response (percent of patients) in Adult RA Patients (Studies RA and RA II)Study RA IStudy RA IIREMICADE+MTXREMICADE+MTX3 mg/kg10 mg/kg3 mg/kg6 mg/kgResponsePlacebo+MTXq8 wksq4 wksq8 wksq4 wksPlacebo+MTXq8 wksq8 wks(n=88)(n=86)(n=86)(n=87)(n=81)(n=274)(n=351)(n=355)ACR 20Week 3020%50%P<=0.001 50% 52% 58% N/AN/AN/AWeek 5417%42% 48% 59% 59% 54%62%P<0.05 66% ACR 50Week 305%27% 29% 31% 26% N/AN/AN/AWeek 549%21% 34% 40% 38% 32%46% 50% ACR 70Week 300%8%P<0.01 11% 18% 11% N/AN/AN/AWeek 542%11% 18% 26% 19% 21%33% 37% Major clinical responseA major clinical response was defined as 70% ACR response for consecutive months (consecutive visits spanning at least 26 weeks) through Week 102 for Study RA and Week 54 for Study RA II. 0%7% 8% 15% 6% 8%12%17% Table 8: Components of ACR 20 at Baseline and 54 Weeks (Study RA I)Placebo+MTXREMICADE+MTXAll doses/schedules of REMICADE+MTX Parameter (medians)(n=88)(n=340)Baseline Week 54 Baseline Week 54 No. of Tender Joints2416328No. of Swollen Joints1913207PainVisual Analog Scale (0=best, 10=worst) 6.76.16.83.3Physicians Global Assessment 6.55.26.22.1Patients Global Assessment 6.26.26.33.2Disability Index (HAQ-DI)Health Assessment Questionnaire, measurement of categories: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and activities (0=best, 3=worst) 1.81.51.81.3CRP (mg/dL)3.02.32.40.6. Radiographic ResponseStructural damage in both hands and feet was assessed radiographically at Week 54 by the change from baseline in the van der Heijde-modified Sharp (vdH-S) score, composite score of structural damage that measures the number and size of joint erosions and the degree of joint space narrowing in hands/wrists and feet. In Study RA I, approximately 80% of patients had paired X-ray data at 54 weeks and approximately 70% at 102 weeks. The inhibition of progression of structural damage was observed at 54 weeks (Table 9) and maintained through 102 weeks.In Study RA II, >90% of patients had at least evaluable X-rays. Inhibition of progression of structural damage was observed at Weeks 30 and 54 (Table 9) in the REMICADE+MTX groups compared to MTX alone. Patients treated with REMICADE+MTX demonstrated less progression of structural damage compared to MTX alone, whether baseline acute-phase reactants (ESR and CRP) were normal or elevated: patients with elevated baseline acute-phase reactants treated with MTX alone demonstrated mean progression in vdH-S score of 4.2 units compared to patients treated with REMICADE+MTX who demonstrated 0.5 units of progression; patients with normal baseline acute phase reactants treated with MTX alone demonstrated mean progression in vdH-S score of 1.8 units compared to REMICADE+MTX who demonstrated 0.2 units of progression. Of patients receiving REMICADE+MTX, 59% had no progression (vdH-S score <=0 unit) of structural damage compared to 45% of patients receiving MTX alone. In subset of patients who began the study without erosions, REMICADE+MTX maintained an erosion-free state at year in greater proportion of patients than MTX alone, 79% (77/98) vs. 58% (23/40), respectively (P<0.01). Fewer patients in the REMICADE+MTX groups (47%) developed erosions in uninvolved joints compared to MTX alone (59%).Table 9: Radiographic Change from Baseline to Week 54 in Adult RA Patients (Studies RA and RA II)Study RA IStudy RA IIREMICADE+MTXREMICADE+MTX3 mg/kg10 mg/kg3 mg/kg6 mg/kgPlacebo+MTXq8 wksq8 wksPlacebo+MTXq8 wksq8 wks(n=64)(n=71)(n=77)(n=282)(n=359)(n=363)Total ScoreBaseline Mean79786511.311.611.2 Median5557565.15.25.3Change from baseline Mean6.91.3P<0.001 for each outcome against placebo. 0.2 3.70.4 0.5 Median4.00.50.50.40.00.0Erosion ScoreBaseline Mean4444338.38.88.3 Median2529223.03.83.8Change from baseline Mean4.10.2 0.2 3.00.3 0.1 Median2.00.00.50.30.00.0JSN ScoreBaseline Mean3634313.02.92.9 Median2629241.01.01.0Change from baseline Mean2.91.1 0.0 0.60.1 0.2 Median1.50.00.00.00.00.0. Physical Function ResponsePhysical function and disability were assessed using the Health Assessment Questionnaire (HAQ-DI) and the general health-related quality of life questionnaire SF-36.In Study RA I, all doses/schedules of REMICADE+MTX showed significantly greater improvement from baseline in HAQ-DI and SF-36 physical component summary score averaged over time through Week 54 compared to placebo+MTX, and no worsening in the SF-36 mental component summary score. The median (interquartile range) improvement from baseline to Week 54 in HAQ-DI was 0.1 (-0.1, 0.5) for the placebo+MTX group and 0.4 (0.1, 0.9) for REMICADE+MTX (p<0.001). Both HAQ-DI and SF-36 effects were maintained through Week 102. Approximately 80% of patients in all doses/schedules of REMICADE+MTX remained in the trial through 102 weeks.In Study RA II, both REMICADE treatment groups showed greater improvement in HAQ-DI from baseline averaged over time through Week 54 compared to MTX alone; 0.7 for REMICADE+MTX vs. 0.6 for MTX alone (P<=0.001). No worsening in the SF-36 mental component summary score was observed.. 14.6Ankylosing Spondylitis. The safety and efficacy of REMICADE were assessed in randomized, multicenter, double-blind, placebo-controlled study in 279 adult patients with active AS. Patients were between 18 and 74 years of age, and had AS, as defined by the modified New York criteria for Ankylosing Spondylitis. Patients were to have had active disease as evidenced by both Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score >4 (possible range 0-10) and spinal pain >4 (on Visual Analog Scale [VAS] of 0-10). Patients with complete ankylosis of the spine were excluded from study participation, and the use of Disease Modifying Anti-Rheumatic Drugs (DMARDs) and systemic corticosteroids were prohibited. Doses of REMICADE mg/kg or placebo were administered intravenously at Weeks 0, 2, 6, 12 and 18.At 24 weeks, improvement in the signs and symptoms of AS, as measured by the proportion of patients achieving 20% improvement in ASAS response criteria (ASAS 20), was seen in 60% of patients in the REMICADE-treated group vs. 18% of patients in the placebo group (p<0.001). Improvement was observed at Week and maintained through Week 24 (Figure and Table 10).Figure 3: Proportion of Adult AS Patients Who Achieved ASAS 20 ResponseAt 24 weeks, the proportions of patients achieving 50% and 70% improvement in the signs and symptoms of AS, as measured by ASAS response criteria (ASAS 50 and ASAS 70, respectively), were 44% and 28%, respectively, for patients receiving REMICADE, compared to 9% and 4%, respectively, for patients receiving placebo (P<0.001, REMICADE vs. placebo). low level of disease activity (defined as value <20 [on scale of 0-100 mm] in each of the ASAS response parameters) was achieved in 22% of REMICADE-treated patients vs. 1% in placebo-treated patients (P<0.001).Table 10: Components of AS Disease ActivityPlacebo (n=78)REMICADE mg/kg (n=201)Baseline 24 Weeks Baseline 24 Weeks P-value ASAS 20 responseCriteria (Mean) Patient Global AssessmentMeasured on VAS with 0=none and 10=severe 6.66.06.83.8<0.001 Spinal pain 7.36.57.64.0<0.001 BASFIBath Ankylosing Spondylitis Functional Index (BASFI), average of 10 questions 5.85.65.73.6<0.001 InflammationInflammation, average of last questions on the 6-question BASDAI 6.95.86.93.4<0.001Acute Phase Reactants Median CRPCRP normal range 0-1.0 mg/dL (mg/dL)1.71.51.50.4<0.001Spinal Mobility (cm, Mean) Modified Schobers testSpinal mobility normal values: modified Schobers test: >4 cm; chest expansion:>6 cm; tragus to wall: <15 cm; lateral spinal flexion: >10 cm 4.05.04.34.40.75 Chest expansion 3.63.73.33.90.04 Tragus to wall 17.317.416.915.70.02 Lateral spinal flexion 10.611.011.412.90.03The median improvement from baseline in the general health-related quality-of-life questionnaire SF-36 physical component summary score at Week 24 was 10.2 for the REMICADE group vs. 0.8 for the placebo group (P<0.001). There was no change in the SF-36 mental component summary score in either the REMICADE group or the placebo group.Results of this study were similar to those seen in multicenter double-blind, placebo-controlled study of 70 patients with AS.. Figure 3. 14.7Psoriatic Arthritis. Safety and efficacy of REMICADE were assessed in multicenter, double-blind, placebo-controlled study in 200 adult patients with active PsA despite DMARD or NSAID therapy (>=5 swollen joints and >=5 tender joints) with or more of the following subtypes: arthritis involving DIP joints (n=49), arthritis mutilans (n=3), asymmetric peripheral arthritis (n=40), polyarticular arthritis (n=100), and spondylitis with peripheral arthritis (n=8). Patients also had Ps with qualifying target lesion >=2 cm in diameter. Forty-six percent of patients continued on stable doses of methotrexate (<=25 mg/week). During the 24-week double-blind phase, patients received either mg/kg REMICADE or placebo at Weeks 0, 2, 6, 14, and 22 (100 patients in each group). At Week 16, placebo patients with <10% improvement from baseline in both swollen and tender joint counts were switched to REMICADE induction (early escape). At Week 24, all placebo-treated patients crossed over to REMICADE induction. Dosing continued for all patients through Week 46.. Clinical ResponseTreatment with REMICADE resulted in improvement in signs and symptoms, as assessed by the ACR criteria, with 58% of REMICADE-treated patients achieving ACR 20 at Week 14, compared with 11% of placebo-treated patients (P<0.001). The response was similar regardless of concomitant use of methotrexate. Improvement was observed as early as Week 2. At months, the ACR 20/50/70 responses were achieved by 54%, 41%, and 27%, respectively, of patients receiving REMICADE compared to 16%, 4%, and 2%, respectively, of patients receiving placebo. Similar responses were seen in patients with each of the subtypes of PsA, although few patients were enrolled with the arthritis mutilans and spondylitis with peripheral arthritis subtypes.Compared to placebo, treatment with REMICADE resulted in improvements in the components of the ACR response criteria, as well as in dactylitis and enthesopathy (Table 11). The clinical response was maintained through Week 54. Similar ACR responses were observed in an earlier randomized, placebo-controlled study of 104 PsA patients, and the responses were maintained through 98 weeks in an open-label extension phase.Table 11: Components of ACR 20 and Percentage of Adult PsA Patients with or More Joints with Dactylitis and Percentage of Adult PsA Patients with Enthesopathy at Baseline and Week 24PlaceboREMICADE mg/kgP<0.001 for percent change from baseline in all components of ACR 20 at Week 24, P<0.05 for of patients with dactylitis, and P=0.004 for of patients with enthesopathy at Week 24 Patients Randomized (n=100)(n=100)BaselineWeek 24BaselineWeek 24Parameter (medians)No. of Tender JointsScale 0-68 2420206No. of Swollen JointsScale 0-66 129123PainVisual Analog Scale (0=best, 10=worst) 6.45.65.92.6Physicians Global Assessment 6.04.55.61.5Patients Global Assessment 6.15.05.92.5Disability Index (HAQ-DI)Health Assessment Questionnaire, measurement of categories: dressing and grooming, arising, eating, walking, hygiene, reach, grip, and activities (0=best, 3=worst) 1.11.11.10.5CRP (mg/dL)Normal range 0-0.6 mg/dL 1.20.91.00.4% Patients with or more digits with dactylitis 41334015% Patients with enthesopathy 35364222Improvement in Psoriasis Area and Severity Index (PASI) in PsA patients with baseline body surface area (BSA) >=3% (n=87 placebo, n=83 REMICADE) was achieved at Week 14, regardless of concomitant methotrexate use, with 64% of REMICADE-treated patients achieving at least 75% improvement from baseline vs. 2% of placebo-treated patients; improvement was observed in some patients as early as Week 2. At months, the PASI 75 and PASI 90 responses were achieved by 60% and 39%, respectively, of patients receiving REMICADE compared to 1% and 0%, respectively, of patients receiving placebo. The PASI response was generally maintained through Week 54. [see Clinical Studies (14.8)]. Radiographic ResponseStructural damage in both hands and feet was assessed radiographically by the change from baseline in the van der Heijde-Sharp (vdH-S) score, modified by the addition of hand DIP joints. The total modified vdH-S score is composite score of structural damage that measures the number and size of joint erosions and the degree of joint space narrowing (JSN) in the hands and feet. At Week 24, REMICADE-treated patients had less radiographic progression than placebo-treated patients (mean change of -0.70 vs. 0.82, P<0.001). REMICADE-treated patients also had less progression in their erosion scores (-0.56 vs 0.51) and JSN scores (-0.14 vs 0.31). The patients in the REMICADE group demonstrated continued inhibition of structural damage at Week 54. Most patients showed little or no change in the vdH-S score during this 12-month study (median change of in both patients who initially received REMICADE or placebo). More patients in the placebo group (12%) had readily apparent radiographic progression compared with the REMICADE group (3%). Physical FunctionPhysical function status was assessed using the HAQ Disability Index (HAQ-DI) and the SF-36 Health Survey. REMICADE-treated patients demonstrated significant improvement in physical function as assessed by HAQ-DI (median percent improvement in HAQ-DI score from baseline to Week 14 and 24 of 43% for REMICADE-treated patients vs 0% for placebo-treated patients).During the placebo-controlled portion of the trial (24 weeks), 54% of REMICADE-treated patients achieved clinically meaningful improvement in HAQ-DI (>=0.3 unit decrease) compared to 22% of placebo-treated patients. REMICADE-treated patients also demonstrated greater improvement in the SF-36 physical and mental component summary scores than placebo-treated patients. The responses were maintained for up to years in an open-label extension study.. 14.8Plaque Psoriasis. The safety and efficacy of REMICADE were assessed in randomized, double-blind, placebo-controlled studies in patients 18 years of age and older with chronic, stable Ps involving >=10% BSA, minimum PASI score of 12, and who were candidates for systemic therapy or phototherapy. Patients with guttate, pustular, or erythrodermic psoriasis were excluded from these studies. No concomitant anti-psoriatic therapies were allowed during the study, with the exception of low-potency topical corticosteroids on the face and groin after Week 10 of study initiation.Study (EXPRESS) evaluated 378 patients who received placebo or REMICADE at dose of mg/kg at Weeks 0, 2, and (induction therapy), followed by maintenance therapy every weeks. At Week 24, the placebo group crossed over to REMICADE induction therapy (5 mg/kg), followed by maintenance therapy every weeks. Patients originally randomized to REMICADE continued to receive REMICADE mg/kg every weeks through Week 46. Across all treatment groups, the median baseline PASI score was 21 and the baseline Static Physician Global Assessment (sPGA) score ranged from moderate (52% of patients) to marked (36%) to severe (2%). In addition, 75% of patients had BSA >20%. Seventy-one percent of patients previously received systemic therapy, and 82% received phototherapy.Study II (EXPRESS II) evaluated 835 patients who received placebo or REMICADE at doses of mg/kg or mg/kg at Weeks 0, 2, and (induction therapy). At Week 14, within each REMICADE dose group, patients were randomized to either scheduled (every weeks) or as needed (PRN) maintenance treatment through Week 46. At Week 16, the placebo group crossed over to REMICADE induction therapy (5 mg/kg), followed by maintenance therapy every weeks. Across all treatment groups, the median baseline PASI score was 18, and 63% of patients had BSA >20%. Fifty-five percent of patients previously received systemic therapy, and 64% received phototherapy.Study III (SPIRIT) evaluated 249 patients who had previously received either psoralen plus ultraviolet treatment (PUVA) or other systemic therapy for their psoriasis. These patients were randomized to receive either placebo or REMICADE at doses of mg/kg or mg/kg at Weeks 0, 2, and 6. At Week 26, patients with sPGA score of moderate or worse (greater than or equal to on scale of to 5) received an additional dose of the randomized treatment. Across all treatment groups, the median baseline PASI score was 19, and the baseline sPGA score ranged from moderate (62% of patients) to marked (22%) to severe (3%). In addition, 75% of patients had BSA >20%. Of the enrolled patients, 114 (46%) received the Week 26 additional dose.In Studies I, II and III, the primary endpoint was the proportion of patients who achieved reduction in score of at least 75% from baseline at Week 10 by the PASI (PASI 75). In Study and Study III, another evaluated outcome included the proportion of patients who achieved score of cleared or minimal by the sPGA. The sPGA is 6-category scale ranging from 5 severe to 0 cleared indicating the physicians overall assessment of the psoriasis severity focusing on induration, erythema, and scaling. Treatment success, defined as cleared or minimal, consisted of none or minimal elevation in plaque, up to faint red coloration in erythema, and none or minimal fine scale over <5% of the plaque. Study II also evaluated the proportion of patients who achieved score of clear or excellent by the relative Physicians Global Assessment (rPGA). The rPGA is 6-category scale ranging from 6 worse to 1 clear that was assessed relative to baseline. Overall lesions were graded with consideration to the percent of body involvement as well as overall induration, scaling, and erythema. Treatment success, defined as clear or excellent, consisted of some residual pinkness or pigmentation to marked improvement (nearly normal skin texture; some erythema may be present). The results of these studies are presented in Table 12.Table 12: Adult Psoriasis Studies I, II, and III, Percentage of Patients who Achieved PASI 75 and Percentage who Achieved Treatment Success with Physicians Global Assessment at Week 10PlaceboREMICADE3 mg/kg5 mg/kgPsoriasis Study - patients randomizedPatients with missing data at Week 10 were considered as nonresponders. 77--301 PASI 752 (3%)--242 (80%)P<0.001 compared with placebo sPGA3 (4%)--242 (80%) Psoriasis Study II patients randomized 208313314 PASI 754 (2%)220 (70%) 237 (75%) rPGA2 (1%)217 (69%) 234 (75%) Psoriasis Study III patients randomizedPatients with missing data at Week 10 were imputed by last observation. 5199 99 PASI 753 (6%)71 (72%) 87 (88%) sPGA5 (10%)71 (72%) 89 (90%) In Study I, in the subgroup of patients with more extensive Ps who had previously received phototherapy, 85% of patients on mg/kg REMICADE achieved PASI 75 at Week 10 compared with 4% of patients on placebo.In Study II, in the subgroup of patients with more extensive Ps who had previously received phototherapy, 72% and 77% of patients on mg/kg and mg/kg REMICADE achieved PASI 75 at Week 10 respectively compared with 1% on placebo. In Study II, among patients with more extensive Ps who had failed or were intolerant to phototherapy, 70% and 78% of patients on mg/kg and mg/kg REMICADE achieved PASI 75 at Week 10 respectively, compared with 2% on placebo. Maintenance of response was studied in subset of 292 and 297 REMICADE-treated patients in the mg/kg and mg/kg groups; respectively, in Study II. Stratified by PASI response at Week 10 and investigational site, patients in the active treatment groups were re-randomized to either scheduled or as needed maintenance (PRN) therapy, beginning on Week 14.The groups that received maintenance dose every weeks appear to have greater percentage of patients maintaining PASI 75 through Week 50 as compared to patients who received the as-needed or PRN doses, and the best response was maintained with the mg/kg every 8-week dose. These results are shown in Figure 4. At Week 46, when REMICADE serum concentrations were at trough level, in the every 8-week dose group, 54% of patients in the mg/kg group compared to 36% in the mg/kg group achieved PASI 75. The lower percentage of PASI 75 responders in the mg/kg every 8-week dose group compared to the mg/kg group was associated with lower percentage of patients with detectable trough serum infliximab levels. This may be related in part to higher antibody rates [see Adverse Reactions (6.1)]. In addition, in subset of patients who had achieved response at Week 10, maintenance of response appears to be greater in patients who received REMICADE every weeks at the mg/kg dose. Regardless of whether the maintenance doses are PRN or every weeks, there is decline in response in subpopulation of patients in each group over time. The results of Study through Week 50 in the mg/kg every weeks maintenance dose group were similar to the results from Study II.Figure 4:Proportion of Adult Ps Patients Who Achieved >=75% Improvement in PASI from Baseline through Week 50 (patients randomized at Week 14)Efficacy and safety of REMICADE treatment beyond 50 weeks have not been evaluated in patients with Ps..

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility. 6-month study in CD-1 mice was conducted to assess the tumorigenic potential of cV1q anti-mouse TNF, an analogous antibody. No evidence of tumorigenicity was observed in mice that received intravenous doses of 10 mg/kg or 40 mg/kg cV1q given weekly. The relevance of this study for human risk is unknown. No impairment of fertility or reproductive performance indices were observed in male or female mice that received cV1q, an analogous mouse antibody, at intravenous doses up to 40 mg/kg given weekly.

CLINICAL PHARMACOLOGY SECTION.

12CLINICAL PHARMACOLOGY. 12.1Mechanism of Action. Infliximab neutralizes the biological activity of TNF by binding with high affinity to the soluble and transmembrane forms of TNF and inhibits binding of TNF with its receptors. Infliximab does not neutralize TNF (lymphotoxin-), related cytokine that utilizes the same receptors as TNF. Biological activities attributed to TNF include: induction of pro-inflammatory cytokines such as interleukins (IL) and 6, enhancement of leukocyte migration by increasing endothelial layer permeability and expression of adhesion molecules by endothelial cells and leukocytes, activation of neutrophil and eosinophil functional activity, induction of acute phase reactants and other liver proteins, as well as tissue degrading enzymes produced by synoviocytes and/or chondrocytes. Cells expressing transmembrane TNF bound by infliximab can be lysed in vitro or in vivo. Infliximab inhibits the functional activity of TNF in wide variety of in vitro bioassays utilizing human fibroblasts, endothelial cells, neutrophils, and T-lymphocytes and epithelial cells. The relationship of these biological response markers to the mechanism(s) by which REMICADE exerts its clinical effects is unknown. Anti-TNF antibodies reduce disease activity in the cotton-top tamarin colitis model, and decrease synovitis and joint erosions in murine model of collagen-induced arthritis. Infliximab prevents disease in transgenic mice that develop polyarthritis as result of constitutive expression of human TNF, and when administered after disease onset, allows eroded joints to heal.. 12.2Pharmacodynamics. Elevated concentrations of TNF have been found in involved tissues and fluids of patients with RA, CD, UC, AS, PsA, and Ps. In RA, treatment with REMICADE reduced infiltration of inflammatory cells into inflamed areas of the joint as well as expression of molecules mediating cellular adhesion [E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)], chemoattraction [IL-8 and monocyte chemotactic protein (MCP-1)] and tissue degradation [matrix metalloproteinase (MMP) and 3]. In CD, treatment with REMICADE reduced infiltration of inflammatory cells and TNF production in inflamed areas of the intestine, and reduced the proportion of mononuclear cells from the lamina propria able to express TNF and interferon. After treatment with REMICADE, patients with RA or CD exhibited decreased levels of serum IL-6 and C-reactive protein (CRP) compared to baseline. Peripheral blood lymphocytes from REMICADE-treated patients showed no significant decrease in number or in proliferative responses to in vitro mitogenic stimulation when compared to cells from untreated patients. In PsA, treatment with REMICADE resulted in reduction in the number of T-cells and blood vessels in the synovium and psoriatic skin lesions as well as reduction of macrophages in the synovium. In Ps, REMICADE treatment may reduce the epidermal thickness and infiltration of inflammatory cells. The relationship between these pharmacodynamic activities and the mechanism(s) by which REMICADE exerts its clinical effects is unknown. 12.3Pharmacokinetics. In adults, single intravenous (IV) infusions of mg/kg to 20 mg/kg (two times the maximum recommended dose for any indication) showed linear relationship between the dose administered and the maximum serum concentration. The volume of distribution at steady state was independent of dose and indicated that infliximab was distributed primarily within the vascular compartment. Pharmacokinetic results for single doses of mg/kg to 10 mg/kg in RA, mg/kg in CD, and mg/kg to mg/kg in Ps indicate that the median terminal half-life of infliximab is 7.7 to 9.5 days.Following an initial dose of REMICADE, repeated infusions at and weeks resulted in predictable concentration-time profiles following each treatment. No systemic accumulation of infliximab occurred upon continued repeated treatment with mg/kg or 10 mg/kg at 4- or 8-week intervals. Development of antibodies to infliximab increased infliximab clearance. At weeks after maintenance dose of to 10 mg/kg of REMICADE, median infliximab serum concentrations ranged from approximately 0.5 to mcg/mL; however, infliximab concentrations were not detectable (<0.1 mcg/mL) in patients who became positive for antibodies to infliximab. No major differences in clearance or volume of distribution were observed in patient subgroups defined by age, weight, or gender. It is not known if there are differences in clearance or volume of distribution in patients with marked impairment of hepatic or renal function.Infliximab pharmacokinetic characteristics (including peak and trough concentrations and terminal half-life) were similar in pediatric (aged to 17 years) and adult patients with CD or UC following the administration of mg/kg of REMICADE.

Prior to initiating REMICADE and periodically during therapy, patients should be evaluated for active tuberculosis and tested for latent infection [see Warnings and Precautions (5.1)].. 2.10Administration Instructions Regarding Infusion Reactions. Prior to treatment, ensure appropriate personnel and medication are available to treat reactions (e.g., hypersensitivity, other reactions) that occur during infusion and shortly after infusion. Prior to infusion with REMICADE, patients may be premedicated with histamine-1 receptor antagonists, histamine-2 receptor antagonists, acetaminophen, and/or corticosteroids [see Warnings and Precautions (5.7)].For mild to moderate reactions during the infusion, consider slowing or stopping the infusion. Upon resolution of these reactions, may reinitiate at lower infusion rate and/or with histamine-1 receptor antagonists, histamine-2 receptor antagonists, acetaminophen, and/or corticosteroids. Discontinue the infusion if the mild to moderate reactions reoccur.Discontinue the infusion if severe hypersensitivity reactions occur during the infusion.. 2.11Reconstitution, Dilution, and Administration Instructions. REMICADE is intended for use under the guidance and supervision of healthcare provider. The supplied lyophilized powder must be reconstituted and diluted prior to administration. The infusion solution should be prepared and administered by trained medical professional using aseptic technique by the following procedure:Calculate the dose, total volume of reconstituted REMICADE solution required and the number of REMICADE vials needed. More than one vial may be needed for full dose.Reconstitute each 100 mg REMICADE vial with 10 mL of Sterile Water for Injection, USP, to obtain concentration of 10 mg/mL, using syringe equipped with 21-gauge or smaller needle as follows: Remove the flip-top from the vial and wipe the top with an alcohol swab. Insert the syringe needle into the vial through the center of the rubber stopper and direct the stream of Sterile Water for Injection, USP, to the glass wall of the vial. Gently swirl the solution by rotating the vial to dissolve the lyophilized powder, which has cake-like appearance. Avoid prolonged or vigorous agitation. DO NOT SHAKE. Foaming of the solution on reconstitution is not unusual.Allow the reconstituted solution to stand for minutes. Visually inspect the reconstituted solution for particulate matter and discoloration. The reconstituted solution should be colorless to light yellow and opalescent, and the solution may develop few translucent particles as infliximab is protein. Do not use if the lyophilized powder has not fully dissolved or if opaque particles, discoloration, or other foreign particles are present. Do not store unused reconstituted REMICADE solution. Dilute the total volume of the reconstituted REMICADE solution to 250 mL For volumes greater than 250 mL, either use larger infusion bag (e.g. 500 mL) or multiple 250 mL infusion bags to ensure that the concentration of the infusion solution does not exceed mg/mL. with sterile 0.9% Sodium Chloride Injection, USP, (do not dilute with any other diluent) as follows:Withdraw volume from the 0.9% Sodium Chloride Injection, USP, 250 mL bottle or bag equal to the total volume of reconstituted REMICADE required for dose. Slowly add the total volume of reconstituted REMICADE solution from the vial(s) to the 250 mL infusion bottle or bag.Discard any unused portion of the reconstituted REMICADE solution remaining in the vial(s).Gently invert the bag to mix the solution. The resulting infusion concentration should range between 0.4 mg/mL (minimum recommended concentration) and mg/mL (maximum recommended concentration) of infliximab. The REMICADE infusion should begin within hours of reconstitution and dilution. The infusion must be administered intravenously for at least hours with an infusion set with an in-line, sterile, non-pyrogenic, low-protein-binding filter (pore size of 1.2 um or less).Given that the vials do not contain antibacterial preservatives, discard any unused portion of the infusion solution (do not store for reuse).No physical biochemical compatibility studies have been conducted to evaluate the co-administration of REMICADE with other agents. REMICADE should not be infused concomitantly in the same intravenous line with other agents.. Calculate the dose, total volume of reconstituted REMICADE solution required and the number of REMICADE vials needed. More than one vial may be needed for full dose.. Reconstitute each 100 mg REMICADE vial with 10 mL of Sterile Water for Injection, USP, to obtain concentration of 10 mg/mL, using syringe equipped with 21-gauge or smaller needle as follows: Remove the flip-top from the vial and wipe the top with an alcohol swab. Insert the syringe needle into the vial through the center of the rubber stopper and direct the stream of Sterile Water for Injection, USP, to the glass wall of the vial. Gently swirl the solution by rotating the vial to dissolve the lyophilized powder, which has cake-like appearance. Avoid prolonged or vigorous agitation. DO NOT SHAKE. Foaming of the solution on reconstitution is not unusual.Allow the reconstituted solution to stand for minutes. Visually inspect the reconstituted solution for particulate matter and discoloration. The reconstituted solution should be colorless to light yellow and opalescent, and the solution may develop few translucent particles as infliximab is protein. Do not use if the lyophilized powder has not fully dissolved or if opaque particles, discoloration, or other foreign particles are present. Do not store unused reconstituted REMICADE solution. Remove the flip-top from the vial and wipe the top with an alcohol swab. Insert the syringe needle into the vial through the center of the rubber stopper and direct the stream of Sterile Water for Injection, USP, to the glass wall of the vial. Gently swirl the solution by rotating the vial to dissolve the lyophilized powder, which has cake-like appearance. Avoid prolonged or vigorous agitation. DO NOT SHAKE. Foaming of the solution on reconstitution is not unusual.. Allow the reconstituted solution to stand for minutes. Visually inspect the reconstituted solution for particulate matter and discoloration.

Do not use if the lyophilized powder has not fully dissolved or if opaque particles, discoloration, or other foreign particles are present. Do not store unused reconstituted REMICADE solution.. Dilute the total volume of the reconstituted REMICADE solution to 250 mL For volumes greater than 250 mL, either use larger infusion bag (e.g. 500 mL) or multiple 250 mL infusion bags to ensure that the concentration of the infusion solution does not exceed mg/mL. with sterile 0.9% Sodium Chloride Injection, USP, (do not dilute with any other diluent) as follows:Withdraw volume from the 0.9% Sodium Chloride Injection, USP, 250 mL bottle or bag equal to the total volume of reconstituted REMICADE required for dose. Slowly add the total volume of reconstituted REMICADE solution from the vial(s) to the 250 mL infusion bottle or bag.Discard any unused portion of the reconstituted REMICADE solution remaining in the vial(s).Gently invert the bag to mix the solution. The resulting infusion concentration should range between 0.4 mg/mL (minimum recommended concentration) and mg/mL (maximum recommended concentration) of infliximab. Withdraw volume from the 0.9% Sodium Chloride Injection, USP, 250 mL bottle or bag equal to the total volume of reconstituted REMICADE required for dose. Slowly add the total volume of reconstituted REMICADE solution from the vial(s) to the 250 mL infusion bottle or bag.. Discard any unused portion of the reconstituted REMICADE solution remaining in the vial(s).. Gently invert the bag to mix the solution. The resulting infusion concentration should range between 0.4 mg/mL (minimum recommended concentration) and mg/mL (maximum recommended concentration) of infliximab.. The REMICADE infusion should begin within hours of reconstitution and dilution. The infusion must be administered intravenously for at least hours with an infusion set with an in-line, sterile, non-pyrogenic, low-protein-binding filter (pore size of 1.2 um or less).. Given that the vials do not contain antibacterial preservatives, discard any unused portion of the infusion solution (do not store for reuse).

DOSAGE FORMS & STRENGTHS SECTION.

3DOSAGE FORMS AND STRENGTHS. For injection: 100 mg of infliximab as white lyophilized powder in single-dose vial for reconstitution and dilution.. For injection: 100 mg of infliximab as lyophilized powder in single-dose vial for reconstitution and dilution. (2.11, 3).

DRUG INTERACTIONS SECTION.

7DRUG INTERACTIONS. Other Biological Products- increased risk of serious infections (7.1). 7.1 Other Biological Products. The combination of REMICADE with other biological products used to treat the same conditions as REMICADE is not recommended [see Warnings and Precautions (5.10)].An increased risk of serious infections was seen in clinical studies of other TNF blockers used in combination with anakinra or abatacept, with no added clinical benefit. Because of the nature of the adverse reactions seen with these combinations with TNF blocker therapy, similar toxicities may also result from the combination of anakinra or abatacept with other TNF blockers. Therefore, the combination of REMICADE and anakinra or abatacept is not recommended [see Warnings and Precautions (5.10)].The concomitant use of tocilizumab with biological DMARDs such as TNF antagonists, including REMICADE, should be avoided because of the possibility of increased immunosuppression and increased risk of infection.. 7.2Methotrexate and Other Concomitant Medications. Specific drug interaction studies, including interactions with methotrexate (MTX), have not been conducted. The majority of patients in RA or CD clinical studies received one or more concomitant medications. In RA, concomitant medications besides MTX were nonsteroidal anti-inflammatory agents (NSAIDs), folic acid, corticosteroids and/or narcotics. Concomitant CD medications were antibiotics, antivirals, corticosteroids, 6-MP/AZA and aminosalicylates. In PsA clinical trials, concomitant medications included MTX in approximately half of the patients as well as NSAIDs, folic acid and corticosteroids. Concomitant MTX use may decrease the incidence of anti-infliximab antibody production and increase infliximab concentrations.. 7.3Immunosuppressants. Patients with CD who received immunosuppressants tended to experience fewer infusion reactions compared to patients on no immunosuppressants [see Adverse Reactions (6.1)]. Serum infliximab concentrations appeared to be unaffected by baseline use of medications for the treatment of CD including corticosteroids, antibiotics (metronidazole or ciprofloxacin) and aminosalicylates.. 7.4Cytochrome P450 Substrates. The formation of CYP450 enzymes may be suppressed by increased levels of cytokines (e.g., TNF, IL-1, IL-6, IL-10, IFN) during chronic inflammation. Therefore, it is expected that for molecule that antagonizes cytokine activity, such as infliximab, the formation of CYP450 enzymes could be normalized. Upon initiation or discontinuation of REMICADE in patients being treated with CYP450 substrates with narrow therapeutic index, monitoring of the effect (e.g., warfarin) or drug concentration (e.g., cyclosporine or theophylline) is recommended and the individual dose of the drug product may be adjusted as needed.. 7.5Live Vaccines/Therapeutic Infectious Agents. It is recommended that live vaccines not be given concurrently with REMICADE. It is also recommended that live vaccines not be given to infants after in utero exposure to infliximab for at least months following birth [see Warnings and Precautions (5.13)].It is recommended that therapeutic infectious agents not be given concurrently with REMICADE [see Warnings and Precautions (5.13)].

GERIATRIC USE SECTION.

8.5Geriatric Use. Of the total number of REMICADE-treated patients in RA and Ps clinical studies, 256 (9.6%) were 65 years old and over, while 17 (0.6%) were 75 years old and over. In these trials, no overall differences in safety or effectiveness were observed between geriatric patients (patients >= 65 years old) and younger adult patients (patients 18 to 65 years old). However, the incidence of serious adverse reactions in geriatric patients was higher in both REMICADE and control groups compared to younger adult patients.Of the total number of REMICADE-treated patients in CD, UC, AS, and PsA clinical studies, 76 (3.2%) were 65 years old and over, while (0.4%) were 75 years old and over. In the CD, UC, AS, and PsA studies, there were insufficient numbers of geriatric patients to determine whether they respond differently from younger adults .The incidence of serious infections in REMICADE-treated geriatric patients was greater than in REMICADE-treated younger adult patients; therefore close monitoring of geriatric patients for the development of serious infections is recommended [see Warnings and Precautions (5.1), and Adverse Reactions (6.1)].

HOW SUPPLIED SECTION.

16HOW SUPPLIED/STORAGE AND HANDLING. How SuppliedREMICADE(R) (infliximab) for injection is supplied in carton containing one single-dose vial (NDC 57894-030-01).Each single-dose vial contains 100 mg of infliximab as sterile, preservative-free, white lyophilized powder for reconstitution and dilution (more than one vial may be needed for full dose) [see Dosage and Administration (2.11)]. Storage and HandlingStore unopened REMICADE(R) vials in refrigerator at 2C to 8C (36F to 46F). If needed, unopened REMICADE vials may be stored at room temperatures up to maximum of 30C (86F) for single period of up to months but not exceeding the original expiration date. The new expiration date must be written in the space provided on the carton. Once removed from the refrigerator, REMICADE cannot be returned to the refrigerator.For storage conditions of the reconstituted and diluted product for administration, see Dosage and Administration (2.11).

IMMUNOGENICITY.

6.2Immunogenicity. As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other infliximab products may be misleading.Treatment with REMICADE can be associated with the development of antibodies to infliximab. An enzyme immunoassay (EIA) method was originally used to measure anti-infliximab antibodies in clinical studies of REMICADE. The EIA method is subject to interference by serum infliximab, possibly resulting in an underestimation of the rate of patient antibody formation. separate, drug-tolerant electrochemiluminescence immunoassay (ECLIA) method for detecting antibodies to infliximab was subsequently developed and validated. This method is 60-fold more sensitive than the original EIA. With the ECLIA method, all clinical samples can be classified as either positive or negative for antibodies to infliximab without the need for the inconclusive category.The incidence of antibodies to infliximab was based on the original EIA method in all clinical studies of REMICADE except for the Phase study in pediatric patients with UC where the incidence of antibodies to infliximab was detected using both the EIA and ECLIA methods.. Immunogenicity in Adult PatientsThe incidence of antibodies to infliximab in patients with RA and CD given 3-dose induction regimen followed by maintenance dosing was approximately 10% as assessed through to years of REMICADE treatment. higher incidence of antibodies to infliximab was observed in CD patients receiving REMICADE after drug-free intervals >16 weeks. In PsA study in which 191 patients received mg/kg with or without MTX, antibodies to infliximab occurred in 15% of patients. The majority of antibody-positive patients had low titers. Antibody development was lower among RA and CD patients receiving immunosuppressant therapies such as 6-MP/AZA or MTX. Patients who were antibody-positive were more likely to have higher rates of clearance, have reduced efficacy, and to experience an infusion reaction than were patients who were antibody negative [see Adverse Reactions (6.1)]. In the Ps Study II, which included both the mg/kg and mg/kg doses, antibodies were observed in 36% of patients treated with mg/kg every weeks for year, and in 51% of patients treated with mg/kg every weeks for year.In the Ps Study III, which also included both the mg/kg and mg/kg doses, antibodies were observed in 20% of patients treated with mg/kg induction (weeks 0, and 6), and in 27% of patients treated with mg/kg induction. Despite the increase in antibody formation, the infusion reaction rates in Studies and II in patients treated with mg/kg induction followed by every week maintenance for year and in Study III in patients treated with mg/kg induction (14.1%-23.0%) and serious infusion reaction rates (<1%) were similar to those observed in other study populations. The clinical significance of apparent increased immunogenicity on efficacy and infusion reactions in Ps patients as compared to patients with other diseases treated with REMICADE over the long term is not known.. Immunogenicity in Pediatric Patients with Crohns DiseaseIn Study Peds Crohns, in which all patients received stable doses of 6-MP, AZA, or MTX, excluding inconclusive samples, of 24 patients had antibodies to infliximab. Although 105 patients were tested for antibodies to infliximab, 81 patients were classified as inconclusive because they could not be ruled as negative due to assay interference by the presence of infliximab in the sample.. Immunogenicity in Pediatric Patients with Ulcerative ColitisIn the pediatric UC trial, 58 patients were evaluated for antibodies to infliximab using the EIA as well as the drug-tolerant ECLIA. With the EIA, of 58 (7%) patients had antibodies to infliximab. With the ECLIA, 30 of 58 (52%) patients had antibodies to infliximab. The higher incidence of antibodies to infliximab by the ECLIA method was due to the 60-fold higher sensitivity compared to the EIA method. While EIA-positive patients generally had undetectable trough infliximab concentrations, ECLIA-positive patients could have detectable trough concentrations of infliximab because the ECLIA assay is more sensitive and drug-tolerant.

INFORMATION FOR PATIENTS SECTION.

17PATIENT COUNSELING INFORMATION. Advise the patient or their caregiver to read the FDA-approved patient labeling (Medication Guide). Patients or their caregivers should be advised of the potential benefits and risks of REMICADE. Healthcare providers should instruct their patients or their caregivers to read the Medication Guide before starting REMICADE therapy and to reread it each time they receive an infusion. InfectionsInform patients that REMICADE increases the risk for developing serious infections. Instruct patients of the importance of contacting their healthcare provider if they develop any symptoms of an infection, including tuberculosis, invasive fungal infections, and reactivation of hepatitis virus infections [see Warnings and Precautions (5.1, 5.3)].. MalignanciesMalignancies have been reported among children, adolescents and young adults who received treatment with TNF blockers. Patients should be counseled about the risk of lymphoma and other malignancies while receiving REMICADE [see Warnings and Precautions (5.2)].. HepatotoxicityInstruct patients to seek medical attention if they develop signs or symptoms of hepatotoxicity (e.g., jaundice) [see Warnings and Precautions (5.4)].

LACTATION SECTION.

8.2 Lactation. Risk SummaryPublished literature show that infliximab is present at low levels in human milk. Systemic exposure in breastfed infant is expected to be low because infliximab is largely degraded in the gastrointestinal tract. U.S. multi-center study of 168 women treated with infliximab for inflammatory bowel disease (breast milk samples obtained, n=29) showed that infants exposed to infliximab through breast milk had no increase in rates of infections and developed normally. There are no data on the effects of infliximab on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for REMICADE and any potential adverse effects on the breastfed child from REMICADE or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

12.1Mechanism of Action. Infliximab neutralizes the biological activity of TNF by binding with high affinity to the soluble and transmembrane forms of TNF and inhibits binding of TNF with its receptors. Infliximab does not neutralize TNF (lymphotoxin-), related cytokine that utilizes the same receptors as TNF. Biological activities attributed to TNF include: induction of pro-inflammatory cytokines such as interleukins (IL) and 6, enhancement of leukocyte migration by increasing endothelial layer permeability and expression of adhesion molecules by endothelial cells and leukocytes, activation of neutrophil and eosinophil functional activity, induction of acute phase reactants and other liver proteins, as well as tissue degrading enzymes produced by synoviocytes and/or chondrocytes. Cells expressing transmembrane TNF bound by infliximab can be lysed in vitro or in vivo. Infliximab inhibits the functional activity of TNF in wide variety of in vitro bioassays utilizing human fibroblasts, endothelial cells, neutrophils, and T-lymphocytes and epithelial cells. The relationship of these biological response markers to the mechanism(s) by which REMICADE exerts its clinical effects is unknown. Anti-TNF antibodies reduce disease activity in the cotton-top tamarin colitis model, and decrease synovitis and joint erosions in murine model of collagen-induced arthritis. Infliximab prevents disease in transgenic mice that develop polyarthritis as result of constitutive expression of human TNF, and when administered after disease onset, allows eroded joints to heal.

NONCLINICAL TOXICOLOGY SECTION.

13NONCLINICAL TOXICOLOGY. 13.1Carcinogenesis, Mutagenesis, Impairment of Fertility. 6-month study in CD-1 mice was conducted to assess the tumorigenic potential of cV1q anti-mouse TNF, an analogous antibody. No evidence of tumorigenicity was observed in mice that received intravenous doses of 10 mg/kg or 40 mg/kg cV1q given weekly. The relevance of this study for human risk is unknown. No impairment of fertility or reproductive performance indices were observed in male or female mice that received cV1q, an analogous mouse antibody, at intravenous doses up to 40 mg/kg given weekly.

OVERDOSAGE SECTION.

10OVERDOSAGE. Single doses up to 20 mg/kg have been administered without any direct toxic effect. In case of overdosage, it is recommended that the patient be monitored for any signs or symptoms of adverse reactions or effects [see Warnings and Precautions (5)] and appropriate symptomatic treatment instituted immediately.

PEDIATRIC USE SECTION.

8.4Pediatric Use. The safety and effectiveness of REMICADE have been established in pediatric patients to 17 years of age for induction and maintenance treatment of CD and UC [see Dosage and Administration (2.2, 2.4) and Adverse Reactions (6.1)]. However, the safety and effectiveness of REMICADE in pediatric patients <6 years of age with CD or UC have not been established. The safety and effectiveness of REMICADE in the treatment of pediatric patients with Ps and juvenile rheumatoid arthritis (JRA) have not been established. Pediatric Crohns DiseaseThe safety and effectiveness of REMICADE have been established for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients years of age and older with moderately to severely active CD who have had an inadequate response to conventional therapy. The use of REMICADE for this indication is supported by evidence from randomized, open-label pediatric CD study in 112 pediatric patients aged years and older [see Clinical Studies (14.2)]. REMICADE has been studied only in combination with conventional immunosuppressive therapy in pediatric CD. The longer term (greater than year) safety and effectiveness of REMICADE in pediatric CD patients have not been established in clinical trials.Postmarketing cases of HSTCL have been reported in pediatric patients treated with TNF blockers including REMICADE. Due to the risk of HSTCL, careful risk-benefit assessment should be made when REMICADE is used in combination with other immunosuppressants in pediatric CD patients [see Boxed Warning, Warnings and Precautions (5.2)]. Pediatric Ulcerative ColitisThe safety and effectiveness of REMICADE for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients aged years and older with moderately to severely active UC who have had an inadequate response to conventional therapy have been established. The use of REMICADE for this indication is supported by evidence from adequate and well-controlled studies of REMICADE in adults with additional safety and pharmacokinetic data from an open-label pediatric UC study in 60 pediatric patients aged years and older [see Dosage and Administration (2.4), Adverse Reactions (6.1), and Clinical Studies (14.4)]. The effectiveness of REMICADE in inducing and maintaining mucosal healing in pediatric UC was not established. Although 41 patients had Mayo endoscopy subscore of or at the Week endoscopy, the induction phase was open-label and lacked control group. Only patients had an optional endoscopy at Week 54. Approximately half of the patients were on concomitant immunomodulators (AZA, 6-MP, MTX) at study start.Due to the risk of HSTCL, careful risk-benefit assessment should be made when REMICADE is used in combination with other immunosuppressants in pediatric UC patients [see Boxed Warning and Warnings and Precautions (5.2)].The longer term (greater than year) safety and effectiveness of REMICADE in pediatric UC patients have not been established in clinical trials.. Juvenile Rheumatoid Arthritis (JRA)The safety and effectiveness of REMICADE in the treatment of pediatric patients with juvenile rheumatoid arthritis (JRA) have not been established.The safety and efficacy of REMICADE in patients with JRA were evaluated in multicenter, randomized, placebo-controlled, double-blind study for 14 weeks, followed by double-blind, all-active treatment extension, for maximum of 44 weeks. Patients with active JRA between the ages of and 17 years who had been treated with MTX for at least months were enrolled. Concurrent use of folic acid, oral corticosteroids (<=0.2 mg/kg/day of prednisone or equivalent), NSAIDs, and/or disease modifying antirheumatic drugs (DMARDs) was permitted. Doses of mg/kg REMICADE or placebo were administered intravenously at Weeks 0, and 6. Patients randomized to placebo crossed-over to receive mg/kg REMICADE at Weeks 14, 16, and 20, and then every weeks through Week 44. Patients who completed the study continued to receive open-label treatment with REMICADE for up to years in companion extension study.The study failed to establish the efficacy of REMICADE in the treatment of JRA. Key observations in the study included high placebo response rate and higher rate of immunogenicity than what has been observed in adults. Additionally, higher rate of clearance of infliximab was observed than had been observed in adults.Population pharmacokinetic analysis showed that in pediatric patients with JRA with body weight of up to 35 kg receiving mg/kg REMICADE and pediatric patients with JRA with body weight greater than 35 kg up to adult body weight receiving mg/kg REMICADE, the steady state area under the concentration curve (AUCss) was similar to that observed in adults receiving mg/kg of REMICADE.A total of 60 patients with JRA were treated with doses of mg/kg and 57 patients were treated with doses of mg/kg. The proportion of patients with infusion reactions who received mg/kg REMICADE was 35% (21/60) over 52 weeks compared with 18% (10/57) in patients who received mg/kg over 38 weeks. The most common infusion reactions reported were vomiting, fever, headache, and hypotension. In the mg/kg REMICADE group, patients had serious infusion reaction and patients reported possible anaphylactic reaction (2 of which were among the serious infusion reactions). In the mg/kg REMICADE group, patients had serious infusion reaction, of whom had possible anaphylactic reaction. Two of the patients who experienced serious infusion reactions received REMICADE by rapid infusion (duration of less than hours). Antibodies to infliximab developed in 38% (20/53) of patients who received mg/kg REMICADE compared with 12% (6/49) of patients who received mg/kg.A total of 68% (41/60) of patients who received mg/kg REMICADE in combination with MTX experienced an infection over 52 weeks compared with 65% (37/57) of patients who received mg/kg REMICADE in combination with MTX over 38 weeks. The most commonly reported infections were upper respiratory tract infection and pharyngitis, and the most commonly reported serious infection was pneumonia. Other notable infections included primary varicella infection in patient and herpes zoster in patient.

PHARMACODYNAMICS SECTION.

12.2Pharmacodynamics. Elevated concentrations of TNF have been found in involved tissues and fluids of patients with RA, CD, UC, AS, PsA, and Ps. In RA, treatment with REMICADE reduced infiltration of inflammatory cells into inflamed areas of the joint as well as expression of molecules mediating cellular adhesion [E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)], chemoattraction [IL-8 and monocyte chemotactic protein (MCP-1)] and tissue degradation [matrix metalloproteinase (MMP) and 3]. In CD, treatment with REMICADE reduced infiltration of inflammatory cells and TNF production in inflamed areas of the intestine, and reduced the proportion of mononuclear cells from the lamina propria able to express TNF and interferon. After treatment with REMICADE, patients with RA or CD exhibited decreased levels of serum IL-6 and C-reactive protein (CRP) compared to baseline. Peripheral blood lymphocytes from REMICADE-treated patients showed no significant decrease in number or in proliferative responses to in vitro mitogenic stimulation when compared to cells from untreated patients. In PsA, treatment with REMICADE resulted in reduction in the number of T-cells and blood vessels in the synovium and psoriatic skin lesions as well as reduction of macrophages in the synovium. In Ps, REMICADE treatment may reduce the epidermal thickness and infiltration of inflammatory cells. The relationship between these pharmacodynamic activities and the mechanism(s) by which REMICADE exerts its clinical effects is unknown.

PHARMACOKINETICS SECTION.

12.3Pharmacokinetics. In adults, single intravenous (IV) infusions of mg/kg to 20 mg/kg (two times the maximum recommended dose for any indication) showed linear relationship between the dose administered and the maximum serum concentration. The volume of distribution at steady state was independent of dose and indicated that infliximab was distributed primarily within the vascular compartment. Pharmacokinetic results for single doses of mg/kg to 10 mg/kg in RA, mg/kg in CD, and mg/kg to mg/kg in Ps indicate that the median terminal half-life of infliximab is 7.7 to 9.5 days.Following an initial dose of REMICADE, repeated infusions at and weeks resulted in predictable concentration-time profiles following each treatment. No systemic accumulation of infliximab occurred upon continued repeated treatment with mg/kg or 10 mg/kg at 4- or 8-week intervals. Development of antibodies to infliximab increased infliximab clearance. At weeks after maintenance dose of to 10 mg/kg of REMICADE, median infliximab serum concentrations ranged from approximately 0.5 to mcg/mL; however, infliximab concentrations were not detectable (<0.1 mcg/mL) in patients who became positive for antibodies to infliximab. No major differences in clearance or volume of distribution were observed in patient subgroups defined by age, weight, or gender. It is not known if there are differences in clearance or volume of distribution in patients with marked impairment of hepatic or renal function.Infliximab pharmacokinetic characteristics (including peak and trough concentrations and terminal half-life) were similar in pediatric (aged to 17 years) and adult patients with CD or UC following the administration of mg/kg of REMICADE.

POSTMARKETING EXPERIENCE SECTION.

6.3 Postmarketing Experience. Adverse reactions, some with fatal outcomes, have been identified during post approval use of REMICADE in adult and pediatric patients. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.. Postmarketing Adverse Reactions in Adults and Pediatric PatientsNeutropenia [see Warnings and Precautions (5.6)], agranulocytosis (including infants exposed in utero to infliximab), idiopathic thrombocytopenic purpura, thrombotic thrombocytopenic purpura.Interstitial lung disease (including pulmonary fibrosis/interstitial pneumonitis and rapidly progressive disease).Pericardial effusion, systemic and cutaneous vasculitis.Erythema multiforme, Stevens-Johnson Syndrome, toxic epidermal necrolysis, linear IgA bullous dermatosis (LABD), acute generalized exanthematous pustulosis (AGEP), new onset and worsening psoriasis (all subtypes including pustular, primarily palmoplantar), lichenoid reactions.Peripheral demyelinating disorders (such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, and multifocal motor neuropathy) transverse myelitis, and neuropathies (additional neurologic reactions have also been observed) [see Warnings and Precautions (5.9)].Acute liver failure, jaundice, hepatitis, and cholestasis [see Warnings and Precautions (5.4)].Serious infections [see Warnings and Precautions (5.1)] and vaccine breakthrough infection including bovine tuberculosis (disseminated BCG infection) following vaccination in an infant exposed in utero to infliximab [see Warnings and Precautions (5.13)].

PREGNANCY SECTION.

8.1Pregnancy. Risk SummaryAvailable observational studies in pregnant women exposed to REMICADE showed no increased risk of major malformations among live births as compared to those exposed to non-biologics. However, findings on other birth and maternal outcomes were not consistent across studies of different study design and conduct (see Data). Monoclonal antibodies such as infliximab are transferred across the placenta during the third trimester of pregnancy and may affect immune response in the in utero exposed infant (see Clinical Considerations). Because infliximab does not cross-react with TNF in species other than humans and chimpanzees, animal reproduction studies have not been conducted with REMICADE. In developmental study conducted in mice using an analogous antibody, no evidence of maternal toxicity or fetal harm was observed (see Data).All pregnancies have background risk of birth defect, loss, or other adverse outcomes.The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.. Clinical Considerations. Disease-Associated Maternal and/or Embryo/Fetal RiskPublished data suggest that there is an increased risk of adverse pregnancy outcomes in women with inflammatory bowel disease or rheumatoid arthritis associated with increased disease activity. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2.5 kg) and small for gestational age at birth.. Fetal/Neonatal Adverse ReactionsAs with other IgG antibodies, infliximab crosses the placenta. Infliximab has been detected in the serum of infants up to months following birth. Consequently, these infants may be at increased risk of infection, including disseminated infection which can become fatal. At least six month waiting period following birth is recommended before the administration of live vaccines (e.g., BCG vaccine or other live vaccines, such as the rotavirus vaccine) to these infants [see Warnings and Precautions (5.13)]. Cases of agranulocytosis in infants exposed in utero have also been reported [see Adverse Reactions (6.3)].. Data. Human DataTwo prospective cohort studies were conducted assessing birth outcomes as well as the health status of infants up to the age of one year in women exposed to REMICADE compared to non-biologic comparators including methotrexate, azathioprine, 6-mercaptopurine and systemic corticosteroids used for the treatment of similar diseases. The first study was conducted in an IBD pregnancy registry in the United States and assessed pregnancy outcomes in 294 women with inflammatory bowel disease exposed to REMICADE during pregnancy compared with 515 women on non-biologic treatment. REMICADE exposure was not associated with increased rates of major congenital malformations, miscarriage/stillbirth, infants of low birth weight, small for gestational age, or infection in the first year of life. The second study among IBD and non-IBD patients in Sweden, Finland, and Denmark compared 97, 7, and 166 women exposed to REMICADE to 2,693, 2,499 and 1,268 women on non-biologic systemic therapy, respectively. In this study, comparing pooled data across the three countries, exposure to REMICADE was not associated with increased rates of congenital anomalies or infant death. REMICADE in combination with immunosuppressants (mainly systemic corticosteroids and azathioprine) was associated with increased rates of preterm birth, small for gestational age, low birth weight, and infant hospitalization for infection compared with non-biologic systemic treatment. Although the study did not show any associations with REMICADE monotherapy, the analyses could have been underpowered to detect an association.There were additional methodological limitations with these studies that may account for the study findings in both studies: the concomitant use of other medications or treatments was not controlled and disease severity was not assessed; in the U.S. study, patient reported outcomes were collected without clinical validation. These methodological limitations hinder interpretation of the study results.. Animal DataBecause infliximab products do not cross-react with TNF in species other than humans and chimpanzees, animal reproduction studies have not been conducted with infliximab. An embryofetal development study was conducted in pregnant mice using cV1q anti-mouse TNF, an analogous antibody that selectively inhibits the functional activity of mouse TNF. This antibody administered in mice, during the period of organogenesis on gestation days (GDs) and 12, at IV doses up to 40 mg/kg produced no evidence of maternal toxicity, fetal mortality, or structural abnormalities. Doses of 10 to 15 mg/kg in pharmacodynamic animal models with the anti-TNF analogous antibody produced maximal pharmacologic effectiveness. Analyses of fetal samples on GD 14 indicated placental transfer of the antibody and exposure of the fetuses during organogenesis. In peri- and post-natal development study in mice, no maternal toxicity or adverse developmental effects in offspring were observed when dams were administered IV doses of 10 or 40 mg/kg of the analogous antibody on GDs 6, 12 and 18 and lactation days 3, and 15.

This Medication Guide has been approved by the U.S. Food and Drug AdministrationRevised: October 2021 MEDICATION GUIDE REMICADE(R) (Rem-eh-kaid) (infliximab)for injection, for intravenous useRead the Medication Guide that comes with REMICADE before you receive the first treatment, and before each time you get treatment of REMICADE. This Medication Guide does not take the place of talking with your doctor about your medical condition or treatment. What is the most important information should know about REMICADE REMICADE may cause serious side effects, including: 1. Risk of infection REMICADE is medicine that affects your immune system. REMICADE can lower the ability of your immune system to fight infections. Serious infections have happened in patients receiving REMICADE. These infections include tuberculosis (TB) and infections caused by viruses, fungi or bacteria that have spread throughout the body. Some patients have died from these infections. Your doctor should test you for TB before starting REMICADE.Your doctor should monitor you closely for signs and symptoms of TB during treatment with REMICADE. Before starting REMICADE, tell your doctor if you: think you have an infection. You should not start receiving REMICADE if you have any kind of infection.are being treated for an infection.have signs of an infection, such as fever, cough, flu-like symptoms.have any open cuts or sores on your body.get lot of infections or have infections that keep coming back.have diabetes or an immune system problem. People with these conditions have higher chance for infections.have TB, or have been in close contact with someone with TB.live or have lived in certain parts of the country (such as the Ohio and Mississippi River valleys) where there is an increased risk for getting certain kinds of fungal infections (histoplasmosis, coccidioidomycosis, or blastomycosis). These infections may develop or become more severe if you receive REMICADE. If you do not know if you have lived in an area where histoplasmosis, coccidioidomycosis, or blastomycosis is common, ask your doctor.have or have had hepatitis B.use the medicines KINERET (anakinra), ORENCIA (abatacept), ACTEMRA (tocilizumab), or other medicines called biologics used to treat the same conditions as REMICADE. After starting REMICADE, if you have an infection, any sign of an infection including fever, cough, flu-like symptoms, or have open cuts or sores on your body, call your doctor right away. REMICADE can make you more likely to get infections or make any infection that you have worse. 2. Risk of Cancer There have been cases of unusual cancers in children and teenage patients using tumor necrosis factor (TNF) blocker medicines.For children and adults receiving TNF blocker medicines, including REMICADE, the chances of getting lymphoma or other cancers may increase.Some people receiving TNF blockers, including REMICADE, developed rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men. Also, most people were being treated for Crohns disease or ulcerative colitis with TNF blocker and another medicine called azathioprine or 6-mercaptopurine.People who have been treated for rheumatoid arthritis, Crohns disease, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and plaque psoriasis for long time may be more likely to develop lymphoma. This is especially true for people with very active disease.Some people treated with REMICADE have developed certain kinds of skin cancer. If any changes in the appearance of your skin or growths on your skin occur during or after your treatment with REMICADE, tell your doctor.Patients with Chronic Obstructive Pulmonary Disease (COPD), specific type of lung disease, may have an increased risk for getting cancer while being treated with REMICADE.Some women being treated for rheumatoid arthritis with REMICADE have developed cervical cancer. For women receiving REMICADE, including those over 60 years of age, your doctor may recommend that you continue to be regularly screened for cervical cancer.Tell your doctor if you have ever had any type of cancer. Discuss with your doctor any need to adjust medicines you may be taking.See the section What are the possible side effects of REMICADE below for more information.What is REMICADEREMICADE is prescription medicine that is approved for patients with:Rheumatoid Arthritis adults with moderately to severely active rheumatoid arthritis, along with the medicine methotrexate.Crohns Disease children years and older and adults with Crohns disease who have not responded well to other medicines.Ankylosing Spondylitis in adultsPsoriatic Arthritis in adultsPlaque Psoriasis adult patients with plaque psoriasis that is chronic (does not go away), severe, extensive, and/or disabling. Ulcerative Colitis children years and older and adults with moderately to severely active ulcerative colitis who have not responded well to other medicines.REMICADE blocks the action of protein in your body called tumor necrosis factor-alpha (TNF-alpha). TNF-alpha is made by your bodys immune system. People with certain diseases have too much TNF-alpha that can cause the immune system to attack normal healthy parts of the body. REMICADE can block the damage caused by too much TNF-alpha.It is not known if REMICADE is safe and effective in children under years of age.Who should not receive REMICADEYou should not receive REMICADE if you have:heart failure, unless your doctor has examined you and decided that you are able to receive REMICADE. Talk to your doctor about your heart failure.had an allergic reaction to REMICADE, or any of the other ingredients in REMICADE. See the end of this Medication Guide for complete list of ingredients in REMICADE.What should tell my doctor before starting treatment with REMICADEYour doctor will assess your health before each treatment. Tell your doctor about all of your medical conditions, including if you: have an infection (see What is the most important information should know about REMICADE).have other liver problems including liver failure.have heart failure or other heart conditions. If you have heart failure, it may get worse while you receive REMICADE.have or have had any type of cancer.have had phototherapy (treatment with ultraviolet light or sunlight along with medicine to make your skin sensitive to light) for psoriasis. You may have higher chance of getting skin cancer while receiving REMICADE.have COPD, specific type of lung disease. Patients with COPD may have an increased risk of getting cancer while receiving REMICADE.have or have had condition that affects your nervous system such as: multiple sclerosis, or Guillain-Barre syndrome, orif you experience any numbness or tingling, orif you have had seizure. have recently received or are scheduled to receive vaccine. Adults and children receiving REMICADE should not receive live vaccines (for example, the Bacille Calmette-Guerin [BCG] vaccine) or treatment with weakened bacteria (such as BCG for bladder cancer). Adults and children should have all of their vaccines brought up to date before starting treatment with REMICADE.are pregnant or plan to become pregnant, are breastfeeding or plan to breastfeed. You and your doctor should decide if you should receive REMICADE while you are pregnant or breastfeeding.If you have baby and you were receiving REMICADE during your pregnancy, it is important to tell your babys doctor and other health care professionals about your REMICADE use so they can decide when your baby should receive any vaccine. Certain vaccinations can cause infections.If you received REMICADE while you were pregnant, your baby may be at higher risk for getting an infection. If your baby receives live vaccine within months after birth, your baby may develop infections with serious complications that can lead to death. This includes live vaccines such as the BCG, rotavirus, or any other live vaccines. For other types of vaccines, talk with your doctor.How should receive REMICADEYou will be given REMICADE through needle placed in vein (IV or intravenous infusion) in your arm.Your doctor may decide to give you medicine before starting the REMICADE infusion to prevent or lessen side effects. Only healthcare professional should prepare the medicine and administer it to you.REMICADE will be given to you over period of about hours.If you have side effects from REMICADE, the infusion may need to be adjusted or stopped. In addition, your healthcare professional may decide to treat your symptoms.A healthcare professional will monitor you during the REMICADE infusion and for period of time afterward for side effects. Your doctor may do certain tests while you are receiving REMICADE to monitor you for side effects and to see how well you respond to the treatment.Your doctor will determine the right dose of REMICADE for you and how often you should receive it. Make sure to discuss with your doctor when you will receive infusions and to come in for all your infusions and follow-up appointments.What should avoid while receiving REMICADEDo not take REMICADE together with medicines such as KINERET (anakinra), ORENCIA (abatacept), ACTEMRA (tocilizumab), or other medicines called biologics that are used to treat the same conditions as REMICADE.Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. These include any other medicines to treat Crohns disease, ulcerative colitis, rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis or psoriasis. Know the medicines you take. Keep list of your medicines and show them to your doctor and pharmacist when you get new medicine.What are the possible side effects of REMICADEREMICADE can cause serious side effects, including: See What is the most important information should know about REMICADESerious InfectionsSome patients, especially those 65 years and older have had serious infections while receiving REMICADE. These serious infections include TB and infections caused by viruses, fungi, or bacteria that have spread throughout the body or cause infections in certain areas (such as skin). Some patients die from these infections.

If your doctor feels that you are at risk for TB, you may be treated with medicine for TB before you begin treatment with REMICADE and during treatment with REMICADE.Even if your TB test is negative, your doctor should carefully monitor you for TB infections while you are receiving REMICADE. Patients who had negative TB skin test before receiving REMICADE have developed active TB.If you are chronic carrier of the hepatitis virus, the virus can become active while you are being treated with REMICADE. In some cases, patients have died as result of hepatitis virus being reactivated. Your doctor should do blood test for hepatitis virus before you start treatment with REMICADE and occasionally while you are being treated. Tell your doctor if you have any of the following symptoms: feel unwellpoor appetitetiredness (fatigue)fever, skin rash, or joint painHeart FailureIf you have heart problem called congestive heart failure, your doctor should check you closely while you are receiving REMICADE. Your congestive heart failure may get worse while you are receiving REMICADE. Be sure to tell your doctor of any new or worse symptoms including: shortness of breathswelling of ankles or feetsudden weight gainTreatment with REMICADE may need to be stopped if you get new or worse congestive heart failure. Other Heart Problems Some patients have experienced heart attack (some of which led to death), low blood flow to the heart, or abnormal heart rhythm within 24 hours of beginning their infusion of REMICADE. Symptoms may include chest discomfort or pain, arm pain, stomach pain, shortness of breath, anxiety, lightheadedness, dizziness, fainting, sweating, nausea, vomiting, fluttering or pounding in your chest, and/or fast or slow heartbeat. Tell your doctor right away if you have any of these symptoms. Liver Injury Some patients receiving REMICADE have developed serious liver problems. Tell your doctor if you have: jaundice (skin and eyes turning yellow)dark brown-colored urinepain on the right side of your stomach area (right-sided abdominal pain)feverextreme tiredness (severe fatigue)Blood ProblemsIn some patients receiving REMICADE, the body may not make enough of the blood cells that help fight infections or help stop bleeding.

Tell your doctor if you have: changes in your visionnumbness or tingling in any part of your bodyseizuresweakness in your arms or legsSome patients have experienced stroke within approximately 24 hours of their infusion with REMICADE. Tell your doctor right away if you have symptoms of stroke which may include: numbness or weakness of the face, arm or leg, especially on one side of the body; sudden confusion, trouble speaking or understanding; sudden trouble seeing in one or both eyes, sudden trouble walking, dizziness, loss of balance or coordination or sudden, severe headache. Allergic Reactions Some patients have had allergic reactions to REMICADE. Some of these reactions were severe. These reactions can happen while you are getting your REMICADE treatment or shortly afterward. Your doctor may need to stop or pause your treatment with REMICADE and may give you medicines to treat the allergic reaction. Signs of an allergic reaction can include: hives (red, raised, itchy patches of skin)difficulty breathingchest painhigh or low blood pressurefeverchillsSome patients treated with REMICADE have had delayed allergic reactions. The delayed reactions occurred to 12 days after receiving treatment with REMICADE. Tell your doctor right away if you have any of these signs of delayed allergic reaction to REMICADE: feverrashheadachesore throatmuscle or joint painswelling of the face and handsdifficulty swallowingLupus-like SyndromeSome patients have developed symptoms that are like the symptoms of Lupus. If you develop any of the following symptoms, your doctor may decide to stop your treatment with REMICADE. chest discomfort or pain that does not go awayshortness of breathjoint painrash on the cheeks or arms that gets worse in the sunPsoriasisSome people receiving REMICADE had new psoriasis or worsening of psoriasis they already had. Tell your doctor if you develop red scaly patches or raised bumps on the skin that are filled with pus. Your doctor may decide to stop your treatment with REMICADE. The most common side effects of REMICADE include: respiratory infections, such as sinus infections and sore throatheadachecoughingstomach painInfusion reactions can happen up to hours after your infusion of REMICADE. Symptoms of infusion reactions may include: feverchillschest painlow blood pressure or high blood pressureshortness of breathrashitchingChildren who received REMICADE in studies for Crohns disease showed some differences in side effects compared with adults who received REMICADE for Crohns disease. The side effects that happened more in children were: anemia (low red blood cells), leukopenia (low white blood cells), flushing (redness or blushing), viral infections, neutropenia (low neutrophils, the white blood cells that fight infection), bone fracture, bacterial infection and allergic reactions of the breathing tract. Among patients who received REMICADE for ulcerative colitis in clinical studies, more children had infections as compared with adults.

SERIOUS INFECTIONSPatients treated with REMICADE are at increased risk for developing serious infections that may lead to hospitalization or death [see Warnings and Precautions (5.1) and Adverse Reactions (6.1)]. Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. REMICADE should be discontinued if patient develops serious infection or sepsis. Reported infections include:Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before REMICADE use and during therapy. Treatment for latent infection should be initiated prior to REMICADE use.Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.The risks and benefits of treatment with REMICADE should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection.Patients should be closely monitored for the development of signs and symptoms of infection during and after treatment with REMICADE, including the possible development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy.. Active tuberculosis, including reactivation of latent tuberculosis. Patients with tuberculosis have frequently presented with disseminated or extrapulmonary disease. Patients should be tested for latent tuberculosis before REMICADE use and during therapy. Treatment for latent infection should be initiated prior to REMICADE use.. Invasive fungal infections, including histoplasmosis, coccidioidomycosis, candidiasis, aspergillosis, blastomycosis, and pneumocystosis. Patients with histoplasmosis or other invasive fungal infections may present with disseminated, rather than localized, disease. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. Empiric anti-fungal therapy should be considered in patients at risk for invasive fungal infections who develop severe systemic illness.. Bacterial, viral and other infections due to opportunistic pathogens, including Legionella and Listeria.

USE IN SPECIFIC POPULATIONS SECTION.

8USE IN SPECIFIC POPULATIONS. 8.1Pregnancy. Risk SummaryAvailable observational studies in pregnant women exposed to REMICADE showed no increased risk of major malformations among live births as compared to those exposed to non-biologics. However, findings on other birth and maternal outcomes were not consistent across studies of different study design and conduct (see Data). Monoclonal antibodies such as infliximab are transferred across the placenta during the third trimester of pregnancy and may affect immune response in the in utero exposed infant (see Clinical Considerations). Because infliximab does not cross-react with TNF in species other than humans and chimpanzees, animal reproduction studies have not been conducted with REMICADE. In developmental study conducted in mice using an analogous antibody, no evidence of maternal toxicity or fetal harm was observed (see Data).All pregnancies have background risk of birth defect, loss, or other adverse outcomes.The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.. Clinical Considerations. Disease-Associated Maternal and/or Embryo/Fetal RiskPublished data suggest that there is an increased risk of adverse pregnancy outcomes in women with inflammatory bowel disease or rheumatoid arthritis associated with increased disease activity. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2.5 kg) and small for gestational age at birth.. Fetal/Neonatal Adverse ReactionsAs with other IgG antibodies, infliximab crosses the placenta. Infliximab has been detected in the serum of infants up to months following birth. Consequently, these infants may be at increased risk of infection, including disseminated infection which can become fatal. At least six month waiting period following birth is recommended before the administration of live vaccines (e.g., BCG vaccine or other live vaccines, such as the rotavirus vaccine) to these infants [see Warnings and Precautions (5.13)]. Cases of agranulocytosis in infants exposed in utero have also been reported [see Adverse Reactions (6.3)].. Data. Human DataTwo prospective cohort studies were conducted assessing birth outcomes as well as the health status of infants up to the age of one year in women exposed to REMICADE compared to non-biologic comparators including methotrexate, azathioprine, 6-mercaptopurine and systemic corticosteroids used for the treatment of similar diseases. The first study was conducted in an IBD pregnancy registry in the United States and assessed pregnancy outcomes in 294 women with inflammatory bowel disease exposed to REMICADE during pregnancy compared with 515 women on non-biologic treatment. REMICADE exposure was not associated with increased rates of major congenital malformations, miscarriage/stillbirth, infants of low birth weight, small for gestational age, or infection in the first year of life. The second study among IBD and non-IBD patients in Sweden, Finland, and Denmark compared 97, 7, and 166 women exposed to REMICADE to 2,693, 2,499 and 1,268 women on non-biologic systemic therapy, respectively. In this study, comparing pooled data across the three countries, exposure to REMICADE was not associated with increased rates of congenital anomalies or infant death. REMICADE in combination with immunosuppressants (mainly systemic corticosteroids and azathioprine) was associated with increased rates of preterm birth, small for gestational age, low birth weight, and infant hospitalization for infection compared with non-biologic systemic treatment. Although the study did not show any associations with REMICADE monotherapy, the analyses could have been underpowered to detect an association.There were additional methodological limitations with these studies that may account for the study findings in both studies: the concomitant use of other medications or treatments was not controlled and disease severity was not assessed; in the U.S. study, patient reported outcomes were collected without clinical validation. These methodological limitations hinder interpretation of the study results.. Animal DataBecause infliximab products do not cross-react with TNF in species other than humans and chimpanzees, animal reproduction studies have not been conducted with infliximab. An embryofetal development study was conducted in pregnant mice using cV1q anti-mouse TNF, an analogous antibody that selectively inhibits the functional activity of mouse TNF. This antibody administered in mice, during the period of organogenesis on gestation days (GDs) and 12, at IV doses up to 40 mg/kg produced no evidence of maternal toxicity, fetal mortality, or structural abnormalities. Doses of 10 to 15 mg/kg in pharmacodynamic animal models with the anti-TNF analogous antibody produced maximal pharmacologic effectiveness. Analyses of fetal samples on GD 14 indicated placental transfer of the antibody and exposure of the fetuses during organogenesis. In peri- and post-natal development study in mice, no maternal toxicity or adverse developmental effects in offspring were observed when dams were administered IV doses of 10 or 40 mg/kg of the analogous antibody on GDs 6, 12 and 18 and lactation days 3, and 15.. 8.2 Lactation. Risk SummaryPublished literature show that infliximab is present at low levels in human milk. Systemic exposure in breastfed infant is expected to be low because infliximab is largely degraded in the gastrointestinal tract. U.S. multi-center study of 168 women treated with infliximab for inflammatory bowel disease (breast milk samples obtained, n=29) showed that infants exposed to infliximab through breast milk had no increase in rates of infections and developed normally. There are no data on the effects of infliximab on milk production. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for REMICADE and any potential adverse effects on the breastfed child from REMICADE or from the underlying maternal condition.. 8.4Pediatric Use. The safety and effectiveness of REMICADE have been established in pediatric patients to 17 years of age for induction and maintenance treatment of CD and UC [see Dosage and Administration (2.2, 2.4) and Adverse Reactions (6.1)]. However, the safety and effectiveness of REMICADE in pediatric patients <6 years of age with CD or UC have not been established. The safety and effectiveness of REMICADE in the treatment of pediatric patients with Ps and juvenile rheumatoid arthritis (JRA) have not been established. Pediatric Crohns DiseaseThe safety and effectiveness of REMICADE have been established for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients years of age and older with moderately to severely active CD who have had an inadequate response to conventional therapy. The use of REMICADE for this indication is supported by evidence from randomized, open-label pediatric CD study in 112 pediatric patients aged years and older [see Clinical Studies (14.2)]. REMICADE has been studied only in combination with conventional immunosuppressive therapy in pediatric CD. The longer term (greater than year) safety and effectiveness of REMICADE in pediatric CD patients have not been established in clinical trials.Postmarketing cases of HSTCL have been reported in pediatric patients treated with TNF blockers including REMICADE. Due to the risk of HSTCL, careful risk-benefit assessment should be made when REMICADE is used in combination with other immunosuppressants in pediatric CD patients [see Boxed Warning, Warnings and Precautions (5.2)]. Pediatric Ulcerative ColitisThe safety and effectiveness of REMICADE for reducing signs and symptoms and inducing and maintaining clinical remission in pediatric patients aged years and older with moderately to severely active UC who have had an inadequate response to conventional therapy have been established. The use of REMICADE for this indication is supported by evidence from adequate and well-controlled studies of REMICADE in adults with additional safety and pharmacokinetic data from an open-label pediatric UC study in 60 pediatric patients aged years and older [see Dosage and Administration (2.4), Adverse Reactions (6.1), and Clinical Studies (14.4)]. The effectiveness of REMICADE in inducing and maintaining mucosal healing in pediatric UC was not established. Although 41 patients had Mayo endoscopy subscore of or at the Week endoscopy, the induction phase was open-label and lacked control group. Only patients had an optional endoscopy at Week 54. Approximately half of the patients were on concomitant immunomodulators (AZA, 6-MP, MTX) at study start.Due to the risk of HSTCL, careful risk-benefit assessment should be made when REMICADE is used in combination with other immunosuppressants in pediatric UC patients [see Boxed Warning and Warnings and Precautions (5.2)].The longer term (greater than year) safety and effectiveness of REMICADE in pediatric UC patients have not been established in clinical trials.. Juvenile Rheumatoid Arthritis (JRA)The safety and effectiveness of REMICADE in the treatment of pediatric patients with juvenile rheumatoid arthritis (JRA) have not been established.The safety and efficacy of REMICADE in patients with JRA were evaluated in multicenter, randomized, placebo-controlled, double-blind study for 14 weeks, followed by double-blind, all-active treatment extension, for maximum of 44 weeks. Patients with active JRA between the ages of and 17 years who had been treated with MTX for at least months were enrolled. Concurrent use of folic acid, oral corticosteroids (<=0.2 mg/kg/day of prednisone or equivalent), NSAIDs, and/or disease modifying antirheumatic drugs (DMARDs) was permitted. Doses of mg/kg REMICADE or placebo were administered intravenously at Weeks 0, and 6. Patients randomized to placebo crossed-over to receive mg/kg REMICADE at Weeks 14, 16, and 20, and then every weeks through Week 44. Patients who completed the study continued to receive open-label treatment with REMICADE for up to years in companion extension study.The study failed to establish the efficacy of REMICADE in the treatment of JRA. Key observations in the study included high placebo response rate and higher rate of immunogenicity than what has been observed in adults. Additionally, higher rate of clearance of infliximab was observed than had been observed in adults.Population pharmacokinetic analysis showed that in pediatric patients with JRA with body weight of up to 35 kg receiving mg/kg REMICADE and pediatric patients with JRA with body weight greater than 35 kg up to adult body weight receiving mg/kg REMICADE, the steady state area under the concentration curve (AUCss) was similar to that observed in adults receiving mg/kg of REMICADE.A total of 60 patients with JRA were treated with doses of mg/kg and 57 patients were treated with doses of mg/kg. The proportion of patients with infusion reactions who received mg/kg REMICADE was 35% (21/60) over 52 weeks compared with 18% (10/57) in patients who received mg/kg over 38 weeks. The most common infusion reactions reported were vomiting, fever, headache, and hypotension. In the mg/kg REMICADE group, patients had serious infusion reaction and patients reported possible anaphylactic reaction (2 of which were among the serious infusion reactions). In the mg/kg REMICADE group, patients had serious infusion reaction, of whom had possible anaphylactic reaction. Two of the patients who experienced serious infusion reactions received REMICADE by rapid infusion (duration of less than hours). Antibodies to infliximab developed in 38% (20/53) of patients who received mg/kg REMICADE compared with 12% (6/49) of patients who received mg/kg.A total of 68% (41/60) of patients who received mg/kg REMICADE in combination with MTX experienced an infection over 52 weeks compared with 65% (37/57) of patients who received mg/kg REMICADE in combination with MTX over 38 weeks. The most commonly reported infections were upper respiratory tract infection and pharyngitis, and the most commonly reported serious infection was pneumonia. Other notable infections included primary varicella infection in patient and herpes zoster in patient.. 8.5Geriatric Use. Of the total number of REMICADE-treated patients in RA and Ps clinical studies, 256 (9.6%) were 65 years old and over, while 17 (0.6%) were 75 years old and over. In these trials, no overall differences in safety or effectiveness were observed between geriatric patients (patients >= 65 years old) and younger adult patients (patients 18 to 65 years old). However, the incidence of serious adverse reactions in geriatric patients was higher in both REMICADE and control groups compared to younger adult patients.Of the total number of REMICADE-treated patients in CD, UC, AS, and PsA clinical studies, 76 (3.2%) were 65 years old and over, while (0.4%) were 75 years old and over. In the CD, UC, AS, and PsA studies, there were insufficient numbers of geriatric patients to determine whether they respond differently from younger adults .The incidence of serious infections in REMICADE-treated geriatric patients was greater than in REMICADE-treated younger adult patients; therefore close monitoring of geriatric patients for the development of serious infections is recommended [see Warnings and Precautions (5.1), and Adverse Reactions (6.1)].

WARNINGS AND PRECAUTIONS SECTION.

5WARNINGS AND PRECAUTIONS. Serious infections do not give REMICADE during an active infection. If an infection develops, monitor carefully and stop REMICADE if infection becomes serious. (5.1)Invasive fungal infections for patients who develop systemic illness on REMICADE, consider empiric antifungal therapy for those who reside or travel to regions where mycoses are endemic (5.1)Malignancies the incidence of malignancies, including invasive cervical cancer and lymphoma, was greater in REMICADE treated patients than in controls. Due to the risk of HSTCL carefully assess the risk/benefit especially if the patient has Crohns disease or ulcerative colitis, is male, and is receiving azathioprine or 6-mercaptopurine treatment. (5.2)Hepatitis virus reactivation test for HBV infection before starting REMICADE. Monitor HBV carriers during and several months after therapy. If reactivation occurs, stop REMICADE and begin anti-viral therapy. (5.3)Hepatotoxicity severe hepatic reactions, some fatal or necessitating liver transplantation. Stop REMICADE in cases of jaundice and/or marked liver enzyme elevations. (5.4)Heart failure new onset or worsening symptoms may occur. (4, 5.5)Cytopenias advise patients to seek immediate medical attention if signs and symptoms develop, and consider stopping REMICADE. (5.6)Hypersensitivity serious infusion reactions including anaphylaxis or serum sickness-like reactions may occur. (5.7)Cardiovascular and Cerebrovascular Reactions Cerebrovascular accidents, myocardial infarctions (some fatal), and arrhythmias have been reported during and within 24 hours of initiation of REMICADE infusion. Monitor patients during REMICADE infusion and if serious reaction occurs, discontinue infusion. (5.8)Demyelinating disease exacerbation or new onset may occur. (5.9)Lupus-like syndrome stop REMICADE if syndrome develops. (5.12)Vaccinations and Use of Live Vaccines/Therapeutic Infectious Agents- Prior to initiating REMICADE bring pediatric and adult patients up to date with all vaccinations. Live vaccines or therapeutic infectious agents should not be given with REMICADE. At least six month waiting period following birth is recommended before the administration of live vaccines to infants exposed in utero to infliximab (5.13).. Serious infections do not give REMICADE during an active infection. If an infection develops, monitor carefully and stop REMICADE if infection becomes serious. (5.1). Invasive fungal infections for patients who develop systemic illness on REMICADE, consider empiric antifungal therapy for those who reside or travel to regions where mycoses are endemic (5.1). Malignancies the incidence of malignancies, including invasive cervical cancer and lymphoma, was greater in REMICADE treated patients than in controls. Due to the risk of HSTCL carefully assess the risk/benefit especially if the patient has Crohns disease or ulcerative colitis, is male, and is receiving azathioprine or 6-mercaptopurine treatment. (5.2). Hepatitis virus reactivation test for HBV infection before starting REMICADE. Monitor HBV carriers during and several months after therapy. If reactivation occurs, stop REMICADE and begin anti-viral therapy. (5.3). Hepatotoxicity severe hepatic reactions, some fatal or necessitating liver transplantation. Stop REMICADE in cases of jaundice and/or marked liver enzyme elevations. (5.4). Heart failure new onset or worsening symptoms may occur. (4, 5.5). Cytopenias advise patients to seek immediate medical attention if signs and symptoms develop, and consider stopping REMICADE. (5.6). Hypersensitivity serious infusion reactions including anaphylaxis or serum sickness-like reactions may occur. (5.7). Cardiovascular and Cerebrovascular Reactions Cerebrovascular accidents, myocardial infarctions (some fatal), and arrhythmias have been reported during and within 24 hours of initiation of REMICADE infusion. Monitor patients during REMICADE infusion and if serious reaction occurs, discontinue infusion. (5.8). Demyelinating disease exacerbation or new onset may occur. (5.9). Lupus-like syndrome stop REMICADE if syndrome develops. (5.12). Vaccinations and Use of Live Vaccines/Therapeutic Infectious Agents- Prior to initiating REMICADE bring pediatric and adult patients up to date with all vaccinations. Live vaccines or therapeutic infectious agents should not be given with REMICADE. At least six month waiting period following birth is recommended before the administration of live vaccines to infants exposed in utero to infliximab (5.13).. 5.1Serious Infections. Patients treated with REMICADE are at increased risk for developing serious infections involving various organ systems and sites that may lead to hospitalization or death.Opportunistic infections due to bacterial, mycobacterial, invasive fungal, viral, or parasitic organisms including aspergillosis, blastomycosis, candidiasis, coccidioidomycosis, cryptococcosis, histoplasmosis, legionellosis, listeriosis, pneumocystosis, salmonellosis and tuberculosis have been reported with TNF blockers. Patients have frequently presented with disseminated rather than localized disease.Treatment with REMICADE should not be initiated in patients with an active infection, including clinically important localized infections. Patients greater than 65 years of age, patients with co-morbid conditions and/or patients taking concomitant immunosuppressants such as corticosteroids or methotrexate may be at greater risk of infection. The risks and benefits of treatment should be considered prior to initiating therapy in patients:with chronic or recurrent infection;who have been exposed to tuberculosis;with history of an opportunistic infection;who have resided or traveled in areas of endemic tuberculosis or endemic mycoses, such as histoplasmosis, coccidioidomycosis, or blastomycosis; orwith underlying conditions that may predispose them to infection.. with chronic or recurrent infection;. who have been exposed to tuberculosis;. with history of an opportunistic infection;. who have resided or traveled in areas of endemic tuberculosis or endemic mycoses, such as histoplasmosis, coccidioidomycosis, or blastomycosis; or. with underlying conditions that may predispose them to infection.. TuberculosisCases of reactivation of tuberculosis or new tuberculosis infections have been observed in patients receiving REMICADE, including patients who have previously received treatment for latent or active tuberculosis. Cases of active tuberculosis have also occurred in patients being treated with REMICADE during treatment for latent tuberculosis.Patients should be evaluated for tuberculosis risk factors and tested for latent infection prior to initiating REMICADE and periodically during therapy. Treatment of latent tuberculosis infection prior to therapy with TNF blockers has been shown to reduce the risk of tuberculosis reactivation during therapy. Induration of mm or greater with tuberculin skin testing should be considered positive test result when assessing if treatment for latent tuberculosis is needed prior to initiating REMICADE, even for patients previously vaccinated with Bacille Calmette-Guerin (BCG).Anti-tuberculosis therapy should also be considered prior to initiation of REMICADE in patients with past history of latent or active tuberculosis in whom an adequate course of treatment cannot be confirmed, and for patients with negative test for latent tuberculosis but having risk factors for tuberculosis infection. Consultation with physician with expertise in the treatment of tuberculosis is recommended to aid in the decision whether initiating anti-tuberculosis therapy is appropriate for an individual patient.Tuberculosis should be strongly considered in patients who develop new infection during REMICADE treatment, especially in patients who have previously or recently traveled to countries with high prevalence of tuberculosis, or who have had close contact with person with active tuberculosis.. MonitoringPatients should be closely monitored for the development of signs and symptoms of infection during and after treatment with REMICADE, including the development of tuberculosis in patients who tested negative for latent tuberculosis infection prior to initiating therapy. Tests for latent tuberculosis infection may also be falsely negative while on therapy with REMICADE.REMICADE should be discontinued if patient develops serious infection or sepsis. patient who develops new infection during treatment with REMICADE should be closely monitored, undergo prompt and complete diagnostic workup appropriate for an immunocompromised patient, and appropriate antimicrobial therapy should be initiated.. Invasive Fungal InfectionsFor patients who reside or travel in regions where mycoses are endemic, invasive fungal infection should be suspected if they develop serious systemic illness. Appropriate empiric antifungal therapy should be considered while diagnostic workup is being performed. Antigen and antibody testing for histoplasmosis may be negative in some patients with active infection. When feasible, the decision to administer empiric antifungal therapy in these patients should be made in consultation with physician with expertise in the diagnosis and treatment of invasive fungal infections and should take into account both the risk for severe fungal infection and the risks of antifungal therapy.. 5.2Malignancies. Malignancies, some fatal, have been reported among children, adolescents and young adults who received treatment with TNF blockers (initiation of therapy <=18 years of age), including REMICADE. Approximately half of these cases were lymphomas, including Hodgkins and non-Hodgkins lymphoma. The other cases represented variety of malignancies, including rare malignancies that are usually associated with immunosuppression and malignancies that are not usually observed in children and adolescents. The malignancies occurred after median of 30 months (range to 84 months) after the first dose of TNF blocker therapy. Most of the patients were receiving concomitant immunosuppressants. These cases were reported post-marketing and are derived from variety of sources, including registries and spontaneous postmarketing reports.. LymphomasIn the controlled portions of clinical trials of all the TNF blockers, more cases of lymphoma have been observed among patients receiving TNF blocker compared with control patients. In the controlled and open-label portions of REMICADE clinical trials, patients developed lymphomas among 5707 patients treated with REMICADE (median duration of follow-up 1.0 years) vs. lymphomas in 1600 control patients (median duration of follow-up 0.4 years). In RA patients, lymphomas were observed for rate of 0.08 cases per 100 patient-years of follow-up, which is approximately three-fold higher than expected in the general population. In the combined clinical trial population for RA, CD, PsA, AS, UC, and Ps, lymphomas were observed for rate of 0.10 cases per 100 patient-years of follow-up, which is approximately four-fold higher than expected in the general population. Patients with CD, RA or Ps, particularly patients with highly active disease and/or chronic exposure to immunosuppressant therapies, may be at higher risk (up to several fold) than the general population for the development of lymphoma, even in the absence of TNF blockers. Cases of acute and chronic leukemia have been reported with postmarketing TNF blocker use in RA and other diseases. Even in the absence of TNF blocker therapy, patients with RA may be at higher risk (approximately 2-fold) than the general population for the development of leukemia.. Hepatosplenic T-cell Lymphoma (HSTCL)Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), rare type of T-cell lymphoma, have been reported in patients treated with TNF blockers including REMICADE. These cases have had very aggressive disease course and have been fatal. Almost all patients had received treatment with the immunosuppressants azathioprine or 6-mercaptopurine concomitantly with TNF blocker at or prior to diagnosis. The majority of reported REMICADE cases have occurred in patients with CD or UC and most were in adolescent and young adult males. It is uncertain whether the occurrence of HSTCL is related to TNF blockers or TNF blockers in combination with these other immunosuppressants. When treating patients, consideration of whether to use REMICADE alone or in combination with other immunosuppressants such as azathioprine or 6-mercaptopurine should take into account possibility that there is higher risk of HSTCL with combination therapy versus an observed increased risk of immunogenicity and hypersensitivity reactions with REMICADE monotherapy from the clinical trial data [see Warnings and Precautions (5.7) and Adverse Reactions (6.1)]. Skin CancerMelanoma and Merkel cell carcinoma have been reported in patients treated with TNF blocker therapy, including REMICADE [see Adverse Reactions (6.3)]. Periodic skin examination is recommended for all patients, particularly those with risk factors for skin cancer.. Cervical CancerA population-based retrospective cohort study using data from Swedish national health registries found 2 to fold increase in the incidence of invasive cervical cancer in women with RA treated with REMICADE compared to biologics-naive patients or the general population, particularly those over 60 years of age. causal relationship between REMICADE and cervical cancer cannot be excluded. Periodic screening should continue in women treated with REMICADE [see Adverse Reactions (6.3)]. Other MalignanciesIn the controlled portions of clinical trials of some TNF blockers including REMICADE, more malignancies (excluding lymphoma and nonmelanoma skin cancer [NMSC]) have been observed in patients receiving those TNF blockers compared with control patients. During the controlled portions of REMICADE trials in patients with moderately to severely active RA, CD, PsA, AS, UC, and Ps, 14 patients were diagnosed with malignancies (excluding lymphoma and NMSC) among 4019 REMICADE-treated patients vs. among 1597 control patients (at rate of 0.52/100 patient-years among REMICADE-treated patients vs. rate of 0.11/100 patient-years among control patients), with median duration of follow-up 0.5 years for REMICADE-treated patients and 0.4 years for control patients. Of these, the most common malignancies were breast, colorectal, and melanoma. The rate of malignancies among REMICADE-treated patients was similar to that expected in the general population whereas the rate in control patients was lower than expected.In clinical trial exploring the use of REMICADE in patients with moderate to severe chronic obstructive pulmonary disease (COPD), more malignancies, the majority of lung or head and neck origin, were reported in REMICADE-treated patients compared with control patients. All patients had history of heavy smoking [see Adverse Reactions (6.1)]. Prescribers should exercise caution when considering the use of REMICADE in patients with moderate to severe COPD.Ps patients should be monitored for nonmelanoma skin cancers (NMSCs), particularly those patients who have had prior prolonged phototherapy treatment. In the maintenance portion of clinical trials for REMICADE, NMSCs were more common in patients with previous phototherapy [see Adverse Reactions (6.1)]. The potential role of TNF blockers in the development of malignancies is not known [see Adverse Reactions (6.1)]. Rates in clinical trials for REMICADE cannot be compared to rates in clinical trials of other TNF blockers and may not predict rates observed in broader patient population. Caution should be exercised in considering REMICADE treatment in patients with history of malignancy or in continuing treatment in patients who develop malignancy while receiving REMICADE.. 5.3Hepatitis Virus Reactivation. Use of TNF blockers, including REMICADE, has been associated with reactivation of hepatitis virus (HBV) in patients who are chronic carriers of this virus. In some instances, HBV reactivation occurring in conjunction with TNF blocker therapy has been fatal. The majority of these reports have occurred in patients concomitantly receiving other medications that suppress the immune system, which may also contribute to HBV reactivation. Patients should be tested for HBV infection before initiating TNF blocker therapy, including REMICADE. For patients who test positive for hepatitis surface antigen, consultation with physician with expertise in the treatment of hepatitis is recommended. Adequate data are not available on the safety or efficacy of treating patients who are carriers of HBV with anti-viral therapy in conjunction with TNF blocker therapy to prevent HBV reactivation. Patients who are carriers of HBV and require treatment with TNF blockers should be closely monitored for clinical and laboratory signs of active HBV infection throughout therapy and for several months following termination of therapy. In patients who develop HBV reactivation, TNF blockers should be stopped and antiviral therapy with appropriate supportive treatment should be initiated. The safety of resuming TNF blocker therapy after HBV reactivation is controlled is not known. Therefore, prescribers should exercise caution when considering resumption of TNF blocker therapy in this situation and monitor patients closely.. 5.4Hepatotoxicity. Severe hepatic reactions, including acute liver failure, jaundice, hepatitis and cholestasis, have been reported in postmarketing data in patients receiving REMICADE. Autoimmune hepatitis has been diagnosed in some of these cases. Severe hepatic reactions occurred between weeks to more than year after initiation of REMICADE; elevations in hepatic aminotransferase levels were not noted prior to discovery of the liver injury in many of these cases. Some of these cases were fatal or necessitated liver transplantation. Patients with symptoms or signs of liver dysfunction should be evaluated for evidence of liver injury. If jaundice and/or marked liver enzyme elevations (e.g., >=5 times the upper limit of normal) develop, REMICADE should be discontinued, and thorough investigation of the abnormality should be undertaken. In clinical trials, mild or moderate elevations of ALT and AST have been observed in patients receiving REMICADE without progression to severe hepatic injury [see Adverse Reactions (6.1)].. 5.5 Heart Failure. The use of REMICADE at doses >5 mg/kg is contraindicated in patients with moderate or severe heart failure. randomized, double-blind, placebo-controlled study evaluated the use of REMICADE (5 mg/kg or 10 mg/kg at Weeks 0, 2, and 6) in patients with moderate or severe heart failure [New York Heart Association (NYHA) Functional Class III/IV]. Compared to patients who received placebo, there was higher rate of mortality and higher risk of hospitalization at Week 28 due to heart failure in patients who received the 10 mg/kg REMICADE dose, and higher rates of cardiovascular adverse events in patients who received REMICADE doses of mg/kg and 10 mg/kg.There have been post-marketing reports of new onset and worsening heart failure, with and without identifiable precipitating factors (e.g., pre-existing cardiovascular disease), in REMICADE-treated patients. Some of these patients have been under 50 years of age. If decision is made to administer REMICADE (<= mg/kg) to patients with moderate or severe heart failure or to administer REMICADE (any approved dose) to patients with mild heart failure, they should be closely monitored during therapy, and REMICADE should be discontinued if new or worsening symptoms of heart failure appear [see Contraindications (4) and Adverse Reactions (6.1)].. 5.6Hematologic Reactions. Cases of leukopenia, neutropenia, thrombocytopenia, and pancytopenia, some with fatal outcome, have been reported in patients receiving REMICADE. The causal relationship to REMICADE therapy remains unclear. Although no high-risk group(s) has been identified, caution should be exercised in patients being treated with REMICADE who have ongoing or history of significant hematologic abnormalities. All patients should be advised to seek immediate medical attention if they develop signs and symptoms suggestive of blood dyscrasias or infection (e.g., persistent fever) while on REMICADE. Discontinuation of REMICADE therapy should be considered in patients who develop significant hematologic abnormalities.. 5.7Hypersensitivity. REMICADE has been associated with hypersensitivity reactions that vary in their time of onset and required hospitalization in some cases. Most hypersensitivity reactions (including anaphylaxis, urticaria, dyspnea, and/or hypotension), have occurred during or within hours of REMICADE infusion. However, in some cases, serum sickness-like reactions have been observed in patients after initial REMICADE therapy (i.e., as early as after the second dose), and when REMICADE therapy was reinstituted following an extended period without REMICADE treatment. Symptoms associated with these reactions include fever, rash, headache, sore throat, myalgias, polyarthralgias, hand and facial edema and/or dysphagia. These reactions were associated with marked increase in antibodies to infliximab, loss of detectable serum concentrations of infliximab, and possible loss of drug efficacy. REMICADE should be discontinued for severe hypersensitivity reactions. Medications for the treatment of hypersensitivity reactions (e.g., acetaminophen, antihistamines, corticosteroids and/or epinephrine) should be available for immediate use in the event of reaction [see Dosage and Administration (2.10) and Adverse Reactions (6.1)].In RA, CD and Ps clinical trials, re-administration of REMICADE after period of no treatment resulted in higher incidence of infusion reactions relative to regular maintenance treatment [see Adverse Reactions (6.1)]. In general, the benefit-risk of re-administration of REMICADE after period of no-treatment, especially as re-induction regimen given at weeks 0, and 6, should be carefully considered. In the case where REMICADE maintenance therapy for Ps is interrupted, REMICADE should be reinitiated as single dose followed by maintenance therapy.. 5.8 Cardiovascular and Cerebrovascular Reactions During and After Infusion. Serious cerebrovascular accidents, myocardial ischemia/infarction (some fatal), hypotension, hypertension, and arrhythmias have been reported during and within 24 hours of initiation of REMICADE infusion. Cases of transient visual loss have been reported during or within hours of infusion of REMICADE. Monitor patients during infusion and if serious reaction occurs, discontinue infusion. Further management of reactions should be dictated by signs and symptoms [see Adverse Reactions (6)]. 5.9Neurologic Reactions. REMICADE and other agents that inhibit TNF have been associated with CNS manifestation of systemic vasculitis, seizure and new onset or exacerbation of clinical symptoms and/or radiographic evidence of central nervous system demyelinating disorders, including multiple sclerosis and optic neuritis, and peripheral demyelinating disorders, including Guillain-Barre syndrome. Prescribers should exercise caution in considering the use of REMICADE in patients with these neurologic disorders and should consider discontinuation of REMICADE if these disorders develop.. 5.10Concurrent Administration with Other Biological Products. Serious infections and neutropenia were seen in clinical studies with concurrent use of anakinra and another TNF blocker, etanercept, with no added clinical benefit compared to etanercept alone. Because of the nature of the adverse reactions seen with the concurrent use of etanercept and anakinra therapy, similar toxicities may also result from the concurrent use of anakinra and other TNF blockers. Therefore, the concurrent use of REMICADE and anakinra is not recommended.In clinical studies, concurrent administration of TNF blockers and abatacept have been associated with an increased risk of infections including serious infections compared with TNF blockers alone, without increased clinical benefit. Therefore, the concurrent use of REMICADE and abatacept is not recommended [see Drug Interactions (7.1)].There is insufficient information regarding the concurrent use of REMICADE with other biological products used to treat the same conditions as REMICADE. The concurrent use of REMICADE with these biological products is not recommended because of the possibility of an increased risk of infection [see Drug Interactions (7.1)].. 5.11Switching Between Biological Disease-Modifying Antirheumatic Drugs (DMARDs). Care should be taken when switching from one biologic to another, since overlapping biological activity may further increase the risk of infection.. 5.12Autoimmunity. Treatment with REMICADE may result in the formation of autoantibodies and in the development of lupus-like syndrome. If patient develops symptoms suggestive of lupus-like syndrome following treatment with REMICADE, treatment should be discontinued [see Adverse Reactions (6.1)].. 5.13Vaccinations and Use of Live Vaccines/Therapeutic Infectious Agents. VaccinationsPrior to initiating REMICADE in pediatric and adult patients, update vaccinations in accordance with current vaccination guidelines.. Live Vaccines and Therapeutic Infectious AgentsIn patients receiving TNF blockers, limited data are available on the response to vaccination with live vaccines or on the secondary transmission of infection by live vaccines. Use of live vaccines can result in clinical infections, including disseminated infections. The concurrent administration of live vaccines with REMICADE is not recommended.Fatal outcome due to disseminated BCG infection has been reported in an infant who received BCG vaccine after in utero exposure to infliximab. Infliximab is known to cross the placenta and has been detected up to months following birth. At least six month waiting period following birth is recommended before the administration of any live vaccine to infants exposed in utero to infliximab.Other uses of therapeutic infectious agents such as live attenuated bacteria (e.g., BCG bladder instillation for the treatment of cancer) could result in clinical infections, including disseminated infections. It is recommended that therapeutic infectious agents not be given concurrently with REMICADE.
