The majority of subjects were male (69%), white (91%), and aged 40-64 years old (58%). One third of subjects reported previous biologic use prior to enrollment. Across the clinical development program, 4464 subjects received at least one dose of SILIQ; 3755 subjects were exposed to SILIQ for at least year.Weeks to 12:Data from one multicenter, randomized, placebo-controlled trial (Trial 1), two multicenter, randomized, placebo- and active-controlled trials (Trials and 3), and one dose-finding trial (Trial 4) in plaque psoriasis were pooled to evaluate the safety of SILIQ (210 mg weekly at Weeks 0, 1, and 2, followed by treatments every weeks [Q2W]) compared to placebo for up to 12 weeks after treatment initiation.During the 12-week, randomized treatment period, about 1% of the subjects in the treatment groups (SILIQ, ustekinumab, and placebo) discontinued treatment because of adverse events. Adverse events leading to discontinuation of SILIQ included neutropenia, arthralgia, and urticaria. The proportion of subjects who developed serious adverse events was similar among the SILIQ, ustekinumab, and placebo groups.Table summarizes the adverse reactions that occurred at rate of at least 1% and at higher rate in the SILIQ 210 mg Q2W group than in the placebo group during the 12-week randomized treatment period of the pooled trials.Table 1: Adverse Reactions Occurring in >= 1% of Subjects in the SILIQ Group and More Frequently than in the Placebo Group in Plaque Psoriasis Trials through Week 12a Subjects receiving 210 mg of SILIQ at Weeks 0, 1, and 2, followed by treatment every weeks during the 12-week period.

Through the end of the trial, the exposure-adjusted rates of treatment-emergent serious adverse events were similar to those seen in the 52-week period in the subjects treated with SILIQ.Specific Adverse Reactions:Suicidal Ideation and BehaviorDuring the 12-week randomized treatment period in the pooled trials, one subject in the SILIQ group attempted suicide and none in the placebo or ustekinumab groups. From initiation through Week 52 of the trials, suicidal ideation or behavior occurred in of 4019 subjects (0.2 per 100 subject-years) treated with SILIQ and in of 613 subjects (0.4 per 100 subject-years) treated with ustekinumab.During the course of the clinical trials for plaque psoriasis, suicidal ideation or behavior occurred in 34 of 4464 subjects treated with SILIQ (0.37 per 100 subject-years). Eight of the 10 subjects who attempted or completed suicide had history of depression and/or suicidal ideation or behavior [see Warnings and Precautions (5.1, 5.2)]. InfectionsDuring the 12-week randomized treatment period, infections occurred in 25.4% of the SILIQ group compared to 23.4% of the placebo group. The majority of infections consisted of nasopharyngitis, upper respiratory tract infection, pharyngitis, urinary tract infections, bronchitis, and influenza, and did not necessitate treatment discontinuation. The SILIQ group had higher rate of fungal infections compared to the placebo group (1.8% vs 0.9%). The fungal infections were primarily non-serious skin and mucosal candida infections [see Warnings and Precautions (5.3)]. NeutropeniaDuring the 12-week randomized treatment period, neutropenia occurred in 0.7% of subjects in the SILIQ group. Most adverse reactions of neutropenia were transient. In subjects with normal absolute neutrophil count (ANC) at baseline, reduction in ANC occurred in 6.8% of subjects in the SILIQ group, compared to 3.3% in the ustekinumab group, and 3.6% in the placebo group. Neutropenia >= Grade (< 1000/mm3) occurred in 0.5% of subjects in the SILIQ group compared to 0.2% of subjects in the ustekinumab group and none in the placebo group. From Week to end of trial, the exposure-adjusted rate of treatment-emergent neutropenia was 0.4 per 100 subject-years (0.1 per 100 subject-years were >= Grade 3). No serious infections were associated with cases of neutropenia.. 6.2 Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity with SILIQ. Approximately 3% of subjects treated with SILIQ developed antibodies to brodalumab through the 52-week treatment period. Of the subjects who developed antibodies to brodalumab, none had antibodies that were classified as neutralizing. However, the assay to test for neutralizing antibodies had limitations detecting neutralizing antibodies in the presence of brodalumab; therefore, the incidence of neutralizing antibody development could be underestimated.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 to SILIQ with the incidence of antibodies to other products may be misleading.

BOXED WARNING SECTION.

WARNING: SUICIDAL IDEATION AND BEHAVIOR Suicidal ideation and behavior, including completed suicides, have occurred in patients treated with SILIQ. Prior to prescribing SILIQ, weigh the potential risks and benefits in patients with history of depression and/or suicidal ideation or behavior. Patients with new or worsening suicidal ideation and behavior should be referred to mental health professional, as appropriate. Advise patients and caregivers to seek medical attention for manifestations of suicidal ideation or behavior, new onset or worsening depression, anxiety, or other mood changes [see Warnings and Precautions (5.1)]. Because of the observed suicidal behavior in subjects treated with SILIQ, SILIQ is available only through restricted program under Risk Evaluation and Mitigation Strategy (REMS) called the SILIQ REMS Program [see Warnings and Precautions (5.2)].

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Animal studies have not been conducted to evaluate the carcinogenic or mutagenic potential of SILIQ. The published literature is mixed on the potential effects on malignancy risk due to the inhibition of the IL-17RA, the pharmacological action of SILIQ. Some published literature suggests that IL-17A directly promotes cancer cell invasion, which suggests potential beneficial effect of SILIQ. However, other reports indicate IL-17A promotes T-cell mediated tumor rejection, which suggests potential adverse effect by SILIQ. However, inhibition of the IL-17RA with SILIQ has not been studied in these models. Therefore, the relevance of experimental findings in these models for malignancy risk in humans is unknown.In cynomolgus monkeys, there were no effects on fertility parameters such as changes in reproductive organs or sperm analysis following subcutaneous administration of brodalumab at dose levels up to 90 mg/kg/week for months (26 times the MRHD on mg/kg basis). The monkeys were not mated in this study to evaluate effects on fertility.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Brodalumab is human monoclonal IgG2 antibody that selectively binds to human IL-17RA and inhibits its interactions with cytokines IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, and IL-25. IL-17RA is protein expressed on the cell surface and is required component of receptor complexes utilized by multiple IL-17 family cytokines. Blocking IL-17RA inhibits IL-17 cytokine-induced responses including the release of pro-inflammatory cytokines and chemokines.. 12.2 Pharmacodynamics Elevated levels of IL-17A, IL-17C, and IL-17F are found in psoriatic plaques. Serum IL-17A levels, measured at Weeks 12, 24, and 48 of SILIQ 210 mg every weeks of treatment, were higher than the baseline levels in subjects with moderate to severe plaque psoriasis. The relationship between the pharmacodynamic activity and the mechanism(s) by which brodalumab exerts its clinical effects is unknown.. 12.3 Pharmacokinetics AbsorptionFollowing single subcutaneous dose of 210 mg in subjects with plaque psoriasis, brodalumab reached peak mean (+-SD) serum concentration (Cmax) of 13.4+-7.3 mcg/mL by approximately days post-dose. The mean (+-SD) area-under-the-concentration-time curve (AUC) of brodalumab was 111+-64 mcgoday/mL.Following multiple subcutaneous doses of 210 mg every weeks, steady-state was achieved by Week 4. The mean (+-SD) Cmax was 20.6+-14.6 mcg/mL and the mean (+-SD) AUC over the 2-week dosing interval was 227+-167 mcgoday/mL.Following subcutaneous administration, brodalumab bioavailability was approximately 55%.DistributionFollowing single subcutaneous administration of brodalumab 210 mg in subjects with plaque psoriasis, the mean (+-SD) apparent volume of distribution (Vz/F) of brodalumab was 8.9+-9.4 L.EliminationThe metabolic pathway of brodalumab has not been characterized. As human monoclonal IgG2 antibody, brodalumab is expected to be degraded into small peptides and amino acids via catabolic pathways in manner similar to endogenous IgG.Following single subcutaneous administration of brodalumab 210 mg in subjects with plaque psoriasis, the mean (+-SD) apparent total clearance (CL/F) was 3.0+-3.5 L/day. The clearance of brodalumab increased with decreasing doses due to nonlinear elimination.Dose LinearityBrodalumab exhibited nonlinear pharmacokinetics with exposures that increased greater than dose-proportionally over dose range from 140 mg (approximately 0.67 times the recommended dose) to 350 mg (approximately 1.67 times the recommended dose) following subcutaneous administrations in subjects with plaque psoriasis.WeightBrodalumab trough concentrations were lower in subjects with higher body weight.Specific PopulationsHepatic or Renal ImpairmentNo trials were conducted to assess the effect of hepatic or renal impairment on the pharmacokinetics of brodalumab.Age: Geriatric PopulationPopulation pharmacokinetic analysis indicated that age did not significantly influence the clearance of brodalumab in subjects with plaque psoriasis. Subjects who were 65 years or older had similar brodalumab clearance as compared to subjects less than 65 years old.Drug Interaction StudiesIn subjects with plaque psoriasis, one week following single subcutaneous administration of 210 mg brodalumab, the exposure of midazolam (CYP3A4 substrate) was increased by 24% [see Drug Interactions (7.2)].

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES Three multicenter, randomized, double-blind, controlled trials (Trials 1, 2, and 3) enrolled total of 4373 subjects 18 years of age and older with at least 6-month history of moderate to severe plaque psoriasis, defined as having minimum affected body surface area (BSA) of 10%, Psoriasis Area and Severity Index (PASI) score >= 12, static Physicians Global Assessment (sPGA) score >=3 in the overall assessment (plaque thickness/induration, erythema, and scaling) of psoriasis on severity scale of to 5, and who were candidates for systemic therapy or phototherapy. In all three trials, subjects were randomized to subcutaneous treatment with placebo or SILIQ 210 mg at Weeks 0, 1, and 2, followed by treatments every weeks [Q2W] through Week 12. In the two active comparator trials (Trials and 3), subjects randomized to ustekinumab received 45 mg dose if their weight was less than or equal to 100 kg and 90 mg dose if their weight was greater than 100 kg at Weeks 0, 4, and 16, followed by the same dose every 12 weeks.All three trials assessed the change from baseline to Week 12 compared to placebo in the two co-primary endpoints: 1) PASI 75, the proportion of subjects who achieved at least 75% reduction in the PASI composite score that takes into consideration both the percentage of body surface area affected and the nature and severity of psoriatic changes (induration, erythema, and scaling) within the affected region, and 2) the proportion of subjects with an sPGA of (clear) or (almost clear), and at least 2-point improvement from baseline. In Trials and 3, comparisons were also made to ustekinumab for the primary endpoint of the proportion of subjects who achieved reduction in PASI score of 100% (PASI 100) from baseline at Week 12.Other evaluated outcomes included the proportion of subjects who achieved an sPGA of (clear) at Week 12, and the proportion of subjects who achieved Psoriasis Symptom Inventory (PSI) score of (not at all) or (mild) on every text (itch, redness, scaling, burning, stinging, cracking, flaking, and pain) at Week 12. Baseline demographics and disease characteristics were generally consistent across all treatment groups in all three trials. Subjects were predominantly men (69%) and white (91%), with mean age of 45 years. The mean baseline body weight was 90.5 kg and 28% of subjects had body weight greater than 100 kg. The baseline PASI score ranged from 9.4 to 72 (median: 17.4) and the baseline-affected BSA ranged from 10 to 97% (median: 21%). Baseline sPGA scores ranged from 3 (moderate) (58%) to 5 (very severe) (5%).Approximately 21% of subjects had history of psoriatic arthritis. Approximately 30% of subjects had previously received biologic therapy and 12% of subjects had failed previous biologic therapy.Clinical Response at Week 12The results of Trials 1, 2, and are presented in Table 2.Table 2: Efficacy Results at Week 12 in Adults with Plaque Psoriasis in Trials 1, 2, and (NRIa)aNRI non-responder imputationbCo-primary endpointsEndpointTrial 1Trial 2Trial 3SILIQ210 mg Q2W(N=222)n (%)Placebo(N=220)n (%)SILIQ210 mg Q2W(N=612)n (%)Ustekinumab(N=300)n (%)Placebo(N=309)n (%)SILIQ210 mg Q2W(N=624)n (%)Ustekinumab(N=313)n (%)Placebo(N=315)n (%)PASI 75b response185 (83)6 (3)528 (86)210 (70)25 (8)531 (85)217 (69)19 (6)PASI 100response93 (42)1 (<1)272 (44) 65 (22)2 (1)229 (37) 58 (19)1 (<1)sPGAsuccessclear (0)or almostclear (1)b 168 (76)3 (1)481 (79)183 (61)12 (4)497 (80)179 (57)13 (4)sPGA ofclear (0)93 (42)1 (<1)274 (45)65 (21)2 (1)229 (37)58 (19)1 (<1)Examination of age, gender, race, use of prior systemic or phototherapy, and use of prior biologics did not identify differences in response to SILIQ among these subgroups.At Week 12, compared to subjects in the placebo group, greater proportion of subjects in SILIQ 210 mg Q2W group achieved Psoriasis Symptom Inventory (PSI) score of (not at all) or (mild) on every text (itch, redness, scaling, burning, stinging, cracking, flaking, pain).Maintenance of EffectIn Trial 1, subjects randomized to receive SILIQ and who were responders at Week 12 (i.e., sPGA of or 1) were re-randomized to receive either placebo or SILIQ. Among responders at Week 12, 83% (69/83) of subjects re-randomized to continued treatment with SILIQ 210 mg Q2W maintained this response (sPGA of or 1) at Week 52 compared to none (0/84) who were re-randomized to placebo and withdrawn from SILIQ. In addition, 87% (72/83) of subjects re-randomized to continued treatment with SILIQ 210 mg Q2W achieved PASI 75 response at Week 52 compared to none (0/84) who were re-randomized to placebo and withdrawn from SILIQ.Trials and included re-randomized phase during which subjects originally randomized to receive SILIQ during the first 12 weeks were re-randomized to one of four SILIQ regimens at the Week 12 visit and placebo subjects were crossed over to receive SILIQ 210 mg Q2W. Subjects receiving ustekinumab continued the same treatment until crossed over at Week 52 to SILIQ 210 mg Q2W. For sPGA or responders at Week 12, the percentage of subjects who maintained this response at Week 52 was 79% for subjects treated with SILIQ 210 mg Q2W. For PASI 100 responders at Week 12, 72% of the subjects who continued on SILIQ 210 mg Q2W maintained the response at Week 52.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS 7.1 Live Vaccinations Avoid use of live vaccines in patients treated with SILIQ [see Warnings and Precautions (5.6)]. 7.2 CYP450 Substrates The formation of CYP450 enzymes can be altered by increased levels of certain cytokines (e.g., IL-1, IL-6, IL-10, TNF, IFN) during chronic inflammation. Treatment with SILIQ may modulate serum levels of some cytokines. Therefore, upon initiation or discontinuation of SILIQ in patients who are receiving concomitant drugs which are CYP450 substrates, particularly those with narrow therapeutic index, consider monitoring for effect (e.g., for warfarin) or drug concentration (e.g., for cyclosporine) and consider dosage modification of the CYP450 substrate [see Clinical Pharmacology (12.3)].

GERIATRIC USE SECTION.

8.5 Geriatric Use Of the 3066 plaque psoriasis subjects initially randomized to SILIQ in clinical trials, 192 (6%) were >= 65 years old and no subjects were >= 75 years old. Although no differences in safety or efficacy were observed between older and younger subjects, the number of subjects aged 65 years and older was not sufficient to determine whether they responded differently from younger subjects [see Clinical Pharmacology (12.3)].

LACTATION SECTION.

8.2 Lactation Risk SummaryThere are no data on the presence of brodalumab in human milk, the effects on the breastfed infant, or the effects on milk production. Brodalumab was detected in the milk of lactating cynomolgus monkeys. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for SILIQ and any potential adverse effects on the breastfed infant from SILIQ or from the underlying maternal condition.

MECHANISM OF ACTION SECTION.

12.1 Mechanism of Action Brodalumab is human monoclonal IgG2 antibody that selectively binds to human IL-17RA and inhibits its interactions with cytokines IL-17A, IL-17F, IL-17C, IL-17A/F heterodimer, and IL-25. IL-17RA is protein expressed on the cell surface and is required component of receptor complexes utilized by multiple IL-17 family cytokines. Blocking IL-17RA inhibits IL-17 cytokine-induced responses including the release of pro-inflammatory cytokines and chemokines.

NONCLINICAL TOXICOLOGY SECTION.

13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Animal studies have not been conducted to evaluate the carcinogenic or mutagenic potential of SILIQ. The published literature is mixed on the potential effects on malignancy risk due to the inhibition of the IL-17RA, the pharmacological action of SILIQ. Some published literature suggests that IL-17A directly promotes cancer cell invasion, which suggests potential beneficial effect of SILIQ. However, other reports indicate IL-17A promotes T-cell mediated tumor rejection, which suggests potential adverse effect by SILIQ. However, inhibition of the IL-17RA with SILIQ has not been studied in these models. Therefore, the relevance of experimental findings in these models for malignancy risk in humans is unknown.In cynomolgus monkeys, there were no effects on fertility parameters such as changes in reproductive organs or sperm analysis following subcutaneous administration of brodalumab at dose levels up to 90 mg/kg/week for months (26 times the MRHD on mg/kg basis). The monkeys were not mated in this study to evaluate effects on fertility.

8.4 Pediatric Use The safety and effectiveness of SILIQ have not been evaluated in pediatric patients.

PHARMACODYNAMICS SECTION.

12.2 Pharmacodynamics Elevated levels of IL-17A, IL-17C, and IL-17F are found in psoriatic plaques. Serum IL-17A levels, measured at Weeks 12, 24, and 48 of SILIQ 210 mg every weeks of treatment, were higher than the baseline levels in subjects with moderate to severe plaque psoriasis. The relationship between the pharmacodynamic activity and the mechanism(s) by which brodalumab exerts its clinical effects is unknown.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics AbsorptionFollowing single subcutaneous dose of 210 mg in subjects with plaque psoriasis, brodalumab reached peak mean (+-SD) serum concentration (Cmax) of 13.4+-7.3 mcg/mL by approximately days post-dose. The mean (+-SD) area-under-the-concentration-time curve (AUC) of brodalumab was 111+-64 mcgoday/mL.Following multiple subcutaneous doses of 210 mg every weeks, steady-state was achieved by Week 4. The mean (+-SD) Cmax was 20.6+-14.6 mcg/mL and the mean (+-SD) AUC over the 2-week dosing interval was 227+-167 mcgoday/mL.Following subcutaneous administration, brodalumab bioavailability was approximately 55%.DistributionFollowing single subcutaneous administration of brodalumab 210 mg in subjects with plaque psoriasis, the mean (+-SD) apparent volume of distribution (Vz/F) of brodalumab was 8.9+-9.4 L.EliminationThe metabolic pathway of brodalumab has not been characterized. As human monoclonal IgG2 antibody, brodalumab is expected to be degraded into small peptides and amino acids via catabolic pathways in manner similar to endogenous IgG.Following single subcutaneous administration of brodalumab 210 mg in subjects with plaque psoriasis, the mean (+-SD) apparent total clearance (CL/F) was 3.0+-3.5 L/day. The clearance of brodalumab increased with decreasing doses due to nonlinear elimination.Dose LinearityBrodalumab exhibited nonlinear pharmacokinetics with exposures that increased greater than dose-proportionally over dose range from 140 mg (approximately 0.67 times the recommended dose) to 350 mg (approximately 1.67 times the recommended dose) following subcutaneous administrations in subjects with plaque psoriasis.WeightBrodalumab trough concentrations were lower in subjects with higher body weight.Specific PopulationsHepatic or Renal ImpairmentNo trials were conducted to assess the effect of hepatic or renal impairment on the pharmacokinetics of brodalumab.Age: Geriatric PopulationPopulation pharmacokinetic analysis indicated that age did not significantly influence the clearance of brodalumab in subjects with plaque psoriasis. Subjects who were 65 years or older had similar brodalumab clearance as compared to subjects less than 65 years old.Drug Interaction StudiesIn subjects with plaque psoriasis, one week following single subcutaneous administration of 210 mg brodalumab, the exposure of midazolam (CYP3A4 substrate) was increased by 24% [see Drug Interactions (7.2)].

PREGNANCY SECTION.

8.1 Pregnancy Risk SummaryThere are no human data on SILIQ use in pregnant women to inform drug-associated risk. Human IgG antibodies are known to cross the placental barrier; therefore, SILIQ may be transmitted from the mother to the developing fetus. In combined embryofetal development and pre- and postnatal development study, no adverse developmental effects were observed in infants born to pregnant monkeys after subcutaneous administration of brodalumab during organogenesis through parturition at doses up to 26 times the maximum recommended human dose (MRHD) [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is to 4% and 15 to 20%, respectively.DataAnimal DataA combined embryofetal development and pre- and postnatal development study was conducted in cynomolgus monkeys administered brodalumab. No brodalumab-related effects on embryofetal toxicity or malformations, or on morphological, functional, or immunological development were observed in infants from pregnant monkeys administered weekly subcutaneous doses of brodalumab up to 26 times the MRHD from the beginning of organogenesis to parturition (on mg/kg basis of 90 mg/kg/week).

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Risk SummaryThere are no human data on SILIQ use in pregnant women to inform drug-associated risk. Human IgG antibodies are known to cross the placental barrier; therefore, SILIQ may be transmitted from the mother to the developing fetus. In combined embryofetal development and pre- and postnatal development study, no adverse developmental effects were observed in infants born to pregnant monkeys after subcutaneous administration of brodalumab during organogenesis through parturition at doses up to 26 times the maximum recommended human dose (MRHD) [see Data]. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is to 4% and 15 to 20%, respectively.DataAnimal DataA combined embryofetal development and pre- and postnatal development study was conducted in cynomolgus monkeys administered brodalumab. No brodalumab-related effects on embryofetal toxicity or malformations, or on morphological, functional, or immunological development were observed in infants from pregnant monkeys administered weekly subcutaneous doses of brodalumab up to 26 times the MRHD from the beginning of organogenesis to parturition (on mg/kg basis of 90 mg/kg/week).. 8.2 Lactation Risk SummaryThere are no data on the presence of brodalumab in human milk, the effects on the breastfed infant, or the effects on milk production. Brodalumab was detected in the milk of lactating cynomolgus monkeys. The developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for SILIQ and any potential adverse effects on the breastfed infant from SILIQ or from the underlying maternal condition.. 8.4 Pediatric Use The safety and effectiveness of SILIQ have not been evaluated in pediatric patients.. 8.5 Geriatric Use Of the 3066 plaque psoriasis subjects initially randomized to SILIQ in clinical trials, 192 (6%) were >= 65 years old and no subjects were >= 75 years old. Although no differences in safety or efficacy were observed between older and younger subjects, the number of subjects aged 65 years and older was not sufficient to determine whether they responded differently from younger subjects [see Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS oInfections: Serious infections have occurred. Consider the risks and benefits prior to initiating SILIQ in patients with chronic infection or history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms of clinically important chronic or acute infection occur. If serious infection develops, discontinue SILIQ until the infection resolves. (5.3)oTuberculosis (TB): Evaluate patients for TB infection prior to initiating treatment with SILIQ. (5.4)oCrohns Disease: Crohns disease occurred during clinical trials. Discontinue SILIQ if patient develops Crohns disease while taking SILIQ. (5.5)oImmunizations: Avoid using live vaccines concurrently with SILIQ. (5.5). oInfections: Serious infections have occurred. Consider the risks and benefits prior to initiating SILIQ in patients with chronic infection or history of recurrent infection. Instruct patients to seek medical advice if signs or symptoms of clinically important chronic or acute infection occur. If serious infection develops, discontinue SILIQ until the infection resolves. (5.3). oTuberculosis (TB): Evaluate patients for TB infection prior to initiating treatment with SILIQ. (5.4). oCrohns Disease: Crohns disease occurred during clinical trials. Discontinue SILIQ if patient develops Crohns disease while taking SILIQ. (5.5). oImmunizations: Avoid using live vaccines concurrently with SILIQ. (5.5). 5.1 Suicidal Ideation and Behavior Suicidal ideation and behavior, including four completed suicides, occurred in subjects treated with SILIQ in the psoriasis clinical trials. There were no completed suicides in the 12-week placebo-controlled portion of the trials. SILIQ users with history of suicidality or depression had an increased incidence of suicidal ideation and behavior as compared to users without such history [see Adverse Reactions (6.1)]. causal association between treatment with SILIQ and increased risk of suicidal ideation and behavior has not been established.Prescribers should weigh the potential risks and benefits before using SILIQ in patients with history of depression or suicidality. Patients with new or worsening symptoms of depression or suicidality should be referred to mental health professional, as appropriate. Advise patients and caregivers to seek medical attention for manifestations of suicidal ideation and behavior, new onset or worsening depression, anxiety, or other mood changes. Prescribers should also re-evaluate the risks and benefits of continuing treatment with SILIQ if such events occur.Because of the observed suicidal ideation and behavior in subjects treated with SILIQ, if an adequate response to SILIQ has not been achieved within 12 to 16 weeks, consider discontinuing therapy. SILIQ is available only through restricted program under REMS [see Warnings and Precautions (5.2)]. 5.2 SILIQ REMS Program SILIQ is available only through restricted program under REMS called the SILIQ REMS Program because of the observed suicidal ideation and behavior in subjects treated with SILIQ [see Warnings and Precautions (5.1)]. Notable requirements of the SILIQ REMS Program include the following:oPrescribers must be certified with the program.oPatients must sign Patient-Prescriber Agreement Form.oPharmacies must be certified with the program and must only dispense to patients who are authorized to receive SILIQ.Further information, including list of qualified pharmacies, is available at www.SILIQREMS.com or by calling the SILIQ REMS Program Call Center at 855-511-6135.. oPrescribers must be certified with the program.. oPatients must sign Patient-Prescriber Agreement Form.. oPharmacies must be certified with the program and must only dispense to patients who are authorized to receive SILIQ.. 5.3 Infections SILIQ may increase the risk of infections. In clinical trials, subjects treated with SILIQ had higher rate of serious infections than subjects treated with placebo (0.5% versus 0.2%) and higher rates of fungal infections (2.4% versus 0.9%). One case of cryptococcal meningitis occurred in subject treated with SILIQ during the 12-week randomized treatment period and led to discontinuation of therapy [see Adverse Reactions (6.1)]. During the course of clinical trials for plaque psoriasis, the exposure-adjusted rates for infections and serious infections were similar in the subjects treated with SILIQ and those treated with ustekinumab.In patients with chronic infection or history of recurrent infection, consider the risks and benefits prior to prescribing SILIQ. Instruct patients to seek medical help if signs or symptoms of clinically important chronic or acute infection occur. If patient develops serious infection or is not responding to standard therapy for the infection, monitor the patient closely and discontinue SILIQ therapy until the infection resolves.. 5.4 Risk for Latent Tuberculosis Reactivation Evaluate patients for tuberculosis (TB) infection prior to initiating treatment with SILIQ. Do not administer SILIQ to patients with active TB infection. Initiate treatment for latent TB prior to administering SILIQ.Consider anti-TB therapy prior to initiation of SILIQ in patients with past history of latent or active TB in whom an adequate course of treatment cannot be confirmed. Closely monitor patients receiving SILIQ for signs and symptoms of active TB during and after treatment.. 5.5 Crohns Disease In psoriasis trials, which excluded subjects with active Crohns disease, Crohns disease occurred in one subject during treatment with SILIQ and led to discontinuation of therapy. In other trials, exacerbation of Crohns disease was observed with SILIQ use.SILIQ is contraindicated in patients with Crohns disease.Discontinue SILIQ if the patient develops Crohns disease while taking SILIQ.. 5.6 Immunizations Avoid use of live vaccines in patients treated with SILIQ. No data are available on the ability of live or inactive vaccines to elicit an immune response in patients being treated with SILIQ.
