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 clinical practice.. Clinical Trials Experience in AdultsThe safety assessment is based on the Week 96 pooled data from 1368 patients in the Phase controlled trials TMC278-C209 (ECHO) and TMC278-C215 (THRIVE) in antiretroviral treatment-naive HIV-1 infected adult patients, 686 of whom received EDURANT (25 mg once daily) [see Clinical Studies (14.1)]. The median duration of exposure for patients in the EDURANT arm and efavirenz arm was 104.3 and 104.1 weeks, respectively. Most ADRs occurred in the first 48 weeks of treatment. The proportion of subjects who discontinued treatment with EDURANT or efavirenz due to ADR, regardless of severity, was 2% and 4%, respectively. The most common ADRs leading to discontinuation were psychiatric disorders: 10 (1%) subjects in the EDURANT arm and 11 (2%) subjects in the efavirenz arm. Rash led to discontinuation in (0.1%) subject in the EDURANT arm and 10 (1.5%) subjects in the efavirenz arm.. Common Adverse Drug ReactionsADRs of at least moderate intensity (>=Grade 2) reported in at least 2% of adult subjects are presented in Table 2. Selected laboratory abnormalities are included in Table 3.Table 2: Selected Adverse Drug Reactions of at least Moderate IntensityIntensities are defined as follows: Moderate (discomfort enough to cause interference with usual activity); Severe (incapacitating with inability to work or do usual activity).

The incidence of adverse events in the Phase 2b TMC278-C204 trial was similar to the Phase trials through 96 weeks.. Less Common Adverse Drug ReactionsADRs of at least moderate intensity (>=Grade 2) occurring in less than 2% of antiretroviral treatment-naive subjects receiving EDURANT are listed below by System Organ Class. Some adverse events have been included because of investigators assessment of potential causal relationship and were considered serious or have been reported in more than subject treated with EDURANT.Gastrointestinal Disorders: diarrhea, abdominal discomfortHepatobiliary Disorders: cholecystitis, cholelithiasisMetabolism and Nutrition Disorders: decreased appetiteNervous System Disorders: somnolencePsychiatric Disorders: sleep disorders, anxietyRenal and Urinary Disorders: glomerulonephritis membranous, glomerulonephritis mesangioproliferative, nephrolithiasis. Laboratory Abnormalities in Treatment-Naive SubjectsThe percentage of subjects treated with EDURANT or efavirenz in the Phase trials with selected laboratory abnormalities (Grades to 4), representing worst Grade toxicity are shown in Table 3.Table 3: Selected Changes in Laboratory Parameters (Grades to 4) Observed in Antiretroviral Treatment-Naive HIV-1-Infected Adult Subjects (Week 96 Analysis)Laboratory Parameter Abnormality, (%)DAIDS Toxicity RangePooled Data from the Phase TMC278-C209 and TMC278-C215 TrialsEDURANT BRN=686Efavirenz BRN=682BIOCHEMISTRYBR background regimen; ULN upper limit of normalN number of subjects per treatment groupNote: Percentages were calculated versus the number of subjects in ITT.Increased Creatinine Grade 1>= 1.1-<= 1.3 ULN6%1% Grade 2> 1.3-<= 1.8 ULN1%1% Grade 3> 1.8-<= 3.4 ULN<1%0 Grade 4> 3.4 ULN0<1%Increased AST Grade 1>= 1.25-<= 2.5 ULN16%19% Grade 2> 2.5-<= 5.0 ULN4%7% Grade 3> 5.0-<= 10.0 ULN2%2% Grade 4> 10.0 ULN1%1%Increased ALT Grade 1>= 1.25-<= 2.5 ULN18%20% Grade 2> 2.5-<= 5.0 ULN5%7% Grade 3> 5.0-<= 10.0 ULN1%2% Grade 4> 10.0 ULN1%1%Increased Total Bilirubin Grade 1>= 1.1-<= 1.5 ULN5%<1% Grade 2> 1.5-<= 2.5 ULN3%1% Grade 3> 2.5-<= 5.0 ULN1%<1% Grade 4> 5.0 ULN00Increased Total Cholesterol (fasted) Grade 15.18-6.19 mmol/L200-239 mg/dL17%31% Grade 26.20-7.77 mmol/L240-300 mg/dL7%19% Grade 3> 7.77 mmol/L> 300 mg/dL<1%3%Increased LDL Cholesterol (fasted) Grade 13.37-4.12 mmol/L130-159 mg/dL14%26% Grade 24.13-4.90 mmol/L160-190 mg/dL5%13% Grade 3>= 4.91 mmol/L>= 191 mg/dL1%5%Increased Triglycerides (fasted) Grade 25.65-8.48 mmol/L500-750 mg/dL2%2% Grade 38.49-13.56 mmol/L751-1,200 mg/dL1%3% Grade 4> 13.56 mmol/L> 1,200 mg/dL01%. Adrenal FunctionIn the pooled Phase trials, at Week 96, there was an overall mean change from baseline in basal cortisol of -0.69 (-1.12, 0.27) micrograms/dL in the EDURANT group and of -0.02 (-0.48, 0.44) micrograms/dL in the efavirenz group.In the EDURANT group, 43/588 (7.3%) of subjects with normal 250 micrograms ACTH stimulation test at baseline developed an abnormal 250 micrograms ACTH stimulation test (peak cortisol level 18.1 micrograms/dL) during the trial compared to 18/561 (3.2%) in the efavirenz group. Of the subjects who developed an abnormal 250 micrograms ACTH stimulation test during the trial, fourteen subjects in the EDURANT group and nine subjects in the efavirenz group had an abnormal 250 micrograms ACTH stimulation test at Week 96. Overall, there were no serious adverse events, deaths, or treatment discontinuations that could clearly be attributed to adrenal insufficiency. The clinical significance of the higher abnormal rate of 250 micrograms ACTH stimulation tests in the EDURANT group is not known.. Serum CreatinineIn the pooled Phase trials, an increase in serum creatinine was observed over the 96 weeks of treatment with EDURANT. Most of this increase occurred within the first four weeks of treatment, with mean change of 0.1 mg/dL (range: -0.3 mg/dL to 0.6 mg/dL) observed after 96 weeks of treatment. In subjects who entered the trial with mild or moderate renal impairment, the serum creatinine increase observed was similar to that seen in subjects with normal renal function. These changes are not considered to be clinically relevant and no subject discontinued treatment due to increases in serum creatinine. Serum creatinine increases occurred regardless of the background N(t)RTI regimen.. Serum LipidsChanges from baseline in total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides are presented in Table 4. The clinical benefit of these findings has not been demonstrated.Table 4: Lipid Values, Mean Change from BaselineExcludes subjects who received lipid lowering agents during the treatment period Pooled Data from the Week 96 Analysis of the Phase TMC278-C209 and TMC278-C215 TrialsEDURANT BREfavirenz BRNBaselineWeek 96NBaselineWeek 96Mean(95% CI)Mean(mg/dL)Mean(mg/dL)Mean ChangeThe change from baseline is the mean of within-patient changes from baseline for patients with both baseline and Week 96 values (mg/dL)Mean(mg/dL)Mean(mg/dL)Mean Change (mg/dL)N number of subjects per treatment group; BR background regimenTotal Cholesterol(fasted)546161 166 507160 187 28 HDL-cholesterol(fasted)54541 46 50540 51 11 LDL-cholesterol(fasted)54396 98 50395 109 14 Triglycerides(fasted)546122 116 -6 507130 141 11 Subjects Co-infected with Hepatitis and/or Hepatitis VirusIn subjects co-infected with hepatitis or virus receiving EDURANT, the incidence of hepatic enzyme elevation was higher than in subjects receiving EDURANT who were not co-infected. This observation was the same in the efavirenz arm. The pharmacokinetic exposure of rilpivirine in co-infected subjects was comparable to that in subjects without co-infection.. Use in Combination with CabotegravirSafety findings from Phase trials in adults were similar when EDURANT was administered in combination with VOCABRIA (cabotegravir) or other antiretrovirals. See full prescribing information for VOCABRIA and CABENUVA (cabotegravir; rilpivirine) extended-release injectable suspensions for additional information.. Clinical Trials Experience in Pediatric PatientsThe safety assessment is based on the Week 48 analysis of the single-arm, open-label, Phase trial, TMC278-C213, in which 36 antiretroviral treatment-naive HIV-1 infected patients 12 to less than 18 years of age and weighing at least 32 kg received EDURANT (25 mg once daily) in combination with other antiretroviral agents [see Clinical Studies (14.3)]. The median duration of exposure was 63.5 weeks. There were no patients who discontinued treatment due to ADRs. No new ADRs were identified compared to those seen in adults.ADRs were reported in nineteen pediatric subjects (52.8%). Most ADRs were Grade or 2. The most common ADRs reported in at least subjects (regardless of severity) include headache (19.4%), depression (19.4%), somnolence (13.9%), nausea (11.1%), dizziness (8.3%), abdominal pain (8.3), vomiting (5.6%) and rash (5.6%).Observed laboratory abnormalities were comparable to those in adults.. Adrenal FunctionIn trial TMC278 C213, at Week 48, the overall mean change from baseline in basal cortisol showed an increase of 1.59 (0.24, 2.93) micrograms/dL.Six of 30 (20%) subjects with normal 250 micrograms ACTH stimulation test at baseline developed an abnormal 250 micrograms ACTH stimulation test (peak cortisol level 18.1 micrograms/dL) during the trial. Three of these subjects had an abnormal 250 micrograms ACTH stimulation test at Week 48. Overall, there were no serious adverse events, deaths, or treatment discontinuations that could clearly be attributed to adrenal insufficiency. The clinical significance of the abnormal 250 micrograms ACTH stimulation tests is not known.. 6.2Postmarketing Experience. Adverse reactions have been identified during postmarketing experience in patients receiving rilpivirine containing regimen. Because these reactions are reported voluntarily from population of unknown size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.Renal and Genitourinary Disorders: nephrotic syndromeSkin and Subcutaneous Tissue Disorders: Severe skin and hypersensitivity reactions including DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms).

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Rilpivirine is an antiviral drug [see Microbiology (12.4)].. 12.2 Pharmacodynamics. Effects on ElectrocardiogramThe effect of EDURANT at the recommended dose of 25 mg once daily on the QTcF interval was evaluated in randomized, placebo and active (moxifloxacin 400 mg once daily) controlled crossover study in 60 healthy adults, with 13 measurements over 24 hours at steady state. The maximum mean time-matched (95% upper confidence bound) differences in QTcF interval from placebo after baseline-correction was 2.0 (5.0) milliseconds (i.e., below the threshold of clinical concern).When doses of 75 mg once daily and 300 mg once daily of EDURANT (3 times and 12 times the dose in EDURANT) were studied in healthy adults, the maximum mean time-matched (95% upper confidence bound) differences in QTcF interval from placebo after baseline-correction were 10.7 (15.3) and 23.3 (28.4) milliseconds, respectively. Steady-state administration of EDURANT 75 mg once daily and 300 mg once daily resulted in mean steady-state Cmax approximately 2.6-fold and 6.7-fold, respectively, higher than the mean Cmax observed with the recommended 25 mg once daily dose of EDURANT [see Warnings and Precautions (5.4)].. 12.3 Pharmacokinetics. Pharmacokinetics in AdultsThe pharmacokinetic properties of rilpivirine have been evaluated in adult healthy subjects and in adult antiretroviral treatment-naive HIV-1-infected subjects. Exposure to rilpivirine was generally lower in HIV-1 infected subjects than in healthy subjects.Table 6: Population Pharmacokinetic Estimates of Rilpivirine 25 mg once daily in Antiretroviral Treatment-Naive HIV-1-Infected Adult Subjects (Pooled Data from Phase Trials through Week 96)ParameterRilpivirine 25 mg once dailyN 679AUC24h (ngh/mL) Mean +- Standard Deviation2235 +- 851 Median (Range)2096 (198 7307)C0h (ng/mL) Mean +- Standard Deviation79 +- 35 Median (Range)73 (2 288). Absorption and BioavailabilityAfter oral administration, the maximum plasma concentration of rilpivirine is generally achieved within 4-5 hours. The absolute bioavailability of EDURANT is unknown.. Effects of Food on Oral AbsorptionThe exposure to rilpivirine was approximately 40% lower when EDURANT was taken in fasted condition as compared to normal caloric meal (533 kcal) or high-fat high-caloric meal (928 kcal). When EDURANT was taken with only protein-rich nutritional drink, exposures were 50% lower than when taken with meal.. DistributionRilpivirine is approximately 99.7% bound to plasma proteins in vitro, primarily to albumin. The distribution of rilpivirine into compartments other than plasma (e.g., cerebrospinal fluid, genital tract secretions) has not been evaluated in humans.. MetabolismIn vitro experiments indicate that rilpivirine primarily undergoes oxidative metabolism mediated by the cytochrome P450 (CYP) 3A system.. EliminationThe terminal elimination half-life of rilpivirine is approximately 50 hours. After single dose oral administration of 14C-rilpivirine, on average 85% and 6.1% of the radioactivity could be retrieved in feces and urine, respectively. In feces, unchanged rilpivirine accounted for on average 25% of the administered dose. Only trace amounts of unchanged rilpivirine (< 1% of dose) were detected in urine.. Special Populations. Pregnancy and PostpartumThe exposure (C0h and AUC24h) to total rilpivirine after intake of rilpivirine 25 mg once daily as part of an antiretroviral regimen was 30 to 40% lower during pregnancy (similar for the second and third trimester), compared with postpartum (see Table 7). However, the exposure during pregnancy was not significantly different from exposures obtained in Phase trials. Based on the exposure-response relationship for rilpivirine, this decrease is not considered clinically relevant in patients who are virollogically suppressed. The protein binding of rilpivirine was similar (>99%) during the second trimester, third trimester, and postpartum.Table 7:Pharmacokinetic Results of Total Rilpivirine After Administration of Rilpivirine 25 mg Once Daily as Part of an Antiretroviral Regimen, During the 2nd Trimester of Pregnancy, the 3rd Trimester of Pregnancy and PostpartumPharmacokinetics of total rilpivirine(mean +- SD, tmax: median [range])Postpartum(6-12 Weeks)(n=11)2nd Trimester of pregnancy(n=15)3rd Trimester of pregnancy(n=13)C0h, ng/mL111 +- 69.265.0 +- 23.963.5 +- 26.2Cmin, ng/mL84.0 +- 58.854.3 +- 25.852.9 +- 24.4Cmax, ng/mL167 +- 101121 +-45.9123 +- 47.5tmax, h4.00 (2.03-25.08)4.00 (1.00-9.00)4.00 (2.00-24.93)AUC24h, ng.h/mL2714 +- 15351792 +- 7111762 +- 662. Pediatric PatientsThe pharmacokinetics of rilpivirine in antiretroviral treatment-naive HIV-1 infected pediatric subjects 12 to less than 18 years of age receiving EDURANT 25 mg once daily were comparable to those in treatment-naive HIV-1 infected adults receiving EDURANT 25 mg once daily. There was no clinically significant impact of body weight on rilpivirine pharmacokinetics in pediatric subjects in trial C213 (33 to 93 kg).Table 8:Population Pharmacokinetic Estimates of Rilpivirine 25 mg once daily in Antiretroviral Treatment-Naive HIV-1-Infected Pediatric Subjects aged 12 to less than 18 years (Data from Phase Trial through Week 48)ParameterRilpivirine 25 mg once dailyN 34AUC24h (ngh/mL) Mean +- Standard Deviation2424 +- 1024 Median (Range)2269 (417 5166)C0h (ng/mL) Mean +- Standard Deviation85 +- 40 Median (Range)79 (7 202)The pharmacokinetics and dosing recommendations of rilpivirine in pediatric patients who are less than 12 years of age and less than 35 kg have not been established [see Use in Specific Populations (8.4)].. Renal ImpairmentPopulation pharmacokinetic analysis indicated that rilpivirine exposure was similar in HIV-1 infected subjects with mild renal impairment relative to HIV-1 infected subjects with normal renal function. No dose adjustment is required in patients with mild renal impairment. There is limited or no information regarding the pharmacokinetics of rilpivirine in patients with moderate or severe renal impairment or in patients with end-stage renal disease, and rilpivirine concentrations may be increased due to alteration of drug absorption, distribution, and metabolism secondary to renal dysfunction. The potential impact is not expected to be of clinical relevance for HIV-1-infected subjects with moderate renal impairment, and no dose adjustment is required in these patients. Rilpivirine should be used with caution and with increased monitoring for adverse effects in patients with severe renal impairment or end-stage renal disease. As rilpivirine is highly bound to plasma proteins, it is unlikely that it will be significantly removed by hemodialysis or peritoneal dialysis [see Use in Specific Populations (8.6)].. Hepatic ImpairmentRilpivirine is primarily metabolized and eliminated by the liver. In study comparing subjects with mild hepatic impairment (Child-Pugh score A) to matched controls, and subjects with moderate hepatic impairment (Child-Pugh score B) to matched controls, the multiple dose exposure of rilpivirine was 47% higher in subjects with mild hepatic impairment and 5% higher in subjects with moderate hepatic impairment. EDURANT has not been studied in subjects with severe hepatic impairment (Child-Pugh score C) [see Use in Specific Populations (8.7)].. Gender, Race, Hepatitis and/or Hepatitis Virus Co-infectionNo clinically relevant differences in the pharmacokinetics of rilpivirine have been observed between gender, race and patients with hepatitis and/or C-virus co-infection.. Drug Interactions[see Contraindications (4) and Drug Interactions (7).] Rilpivirine is primarily metabolized by cytochrome P450 (CYP)3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of rilpivirine. Coadministration of EDURANT and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance. Coadministration of EDURANT and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of EDURANT with drugs that increase gastric pH may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine and to the class of NNRTIs.EDURANT at dose of 25 mg once daily is not likely to have clinically relevant effect on the exposure of medicinal products metabolized by CYP enzymes.Drug interaction studies were performed with EDURANT and other drugs likely to be coadministered or commonly used as probes for pharmacokinetic interactions. The effects of coadministration of other drugs on the Cmax, AUC, and Cmin values of rilpivirine are summarized in Table (effect of other drugs on EDURANT). The effect of coadministration of EDURANT on the Cmax, AUC, and Cmin values of other drugs are summarized in Table 10 (effect of EDURANT on other drugs).

Mechanism of ActionRilpivirine is diarylpyrimidine non-nucleoside reverse transcriptase inhibitor (NNRTI) of human immunodeficiency virus type (HIV-1) and inhibits HIV-1 replication by non-competitive inhibition of HIV-1 reverse transcriptase (RT). Rilpivirine does not inhibit the human cellular DNA polymerases and .. Antiviral Activity in Cell CultureRilpivirine exhibited activity against laboratory strains of wild-type HIV-1 in an acutely infected T-cell line with median EC50 value for HIV-1IIIB of 0.73 nM (0.27 ng/mL). Rilpivirine demonstrated limited activity in cell culture against HIV-2 with median EC50 value of 5220 nM (range 2510 to 10830 nM) (920 to 3970 ng/mL).Rilpivirine demonstrated antiviral activity against broad panel of HIV-1 group (subtype A, B, C, D, F, G, H) primary isolates with EC50 values ranging from 0.07 to 1.01 nM (0.03 to 0.37 ng/mL) and was less active against group primary isolates with EC50 values ranging from 2.88 to 8.45 nM (1.06 to 3.10 ng/mL).The antiviral activity of rilpivirine was not antagonistic when combined with the NNRTIs efavirenz, etravirine or nevirapine; the N(t)RTIs abacavir, didanosine, emtricitabine, lamivudine, stavudine, tenofovir or zidovudine; the PIs amprenavir, atazanavir, darunavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir or tipranavir; the fusion inhibitor enfuvirtide; the CCR5 co-receptor antagonist maraviroc, or the integrase strand transfer inhibitor raltegravir.. Resistance. In Cell CultureRilpivirine-resistant strains were selected in cell culture starting from wild-type HIV-1 of different origins and subtypes as well as NNRTI resistant HIV-1. The frequently observed amino acid substitutions that emerged and conferred decreased phenotypic susceptibility to rilpivirine included: L100I, K101E, V106I and A, V108I, E138K and G, Q, R, V179F and I, Y181C and I, V189I, G190E, H221Y, F227C and M230I and L.. In Treatment-Naive Adult SubjectsIn the Week 96 pooled resistance analysis of the Phase trials C209 and C215, the emergence of resistance was greater among subjects viruses in the EDURANT arm compared to the efavirenz arm, and was dependent on baseline viral load. In the pooled resistance analysis, 58% (57/98) of the subjects who qualified for resistance analysis (resistance analysis subjects) in the EDURANT arm had virus with genotypic and/or phenotypic resistance to rilpivirine compared to 45% (25/56) of the resistance analysis subjects in the efavirenz arm who had genotypic and/or phenotypic resistance to efavirenz. Moreover, genotypic and/or phenotypic resistance to background drug (emtricitabine, lamivudine, tenofovir, abacavir or zidovudine) emerged in viruses from 52% (51/98) of the resistance analysis subjects in the rilpivirine arm compared to 23% (13/56) in the efavirenz arm.Emerging NNRTI substitutions in the rilpivirine resistance analysis of subjects viruses included V90I, K101E/P/T, E138K/A/Q/G, V179I/L, Y181C/I, V189I, H221Y, F227C/L and M230L, which were associated with rilpivirine phenotypic fold change range of 2.6 621. The E138K substitution emerged most frequently during rilpivirine treatment commonly in combination with the M184I substitution. The emtricitabine and lamivudine resistance-associated substitutions M184I or and NRTI resistance-associated substitutions (K65R/N, A62V, D67N/G, K70E, Y115F, T215S/T, or K219E/R) emerged more frequently in rilpivirine resistance analysis subjects compared to efavirenz resistance analysis subjects (see Table 11).NNRTI- and NRTI-resistance substitutions emerged less frequently in resistance analysis of viruses from subjects with baseline viral load of <= 100,000 copies/mL compared to viruses from subjects with baseline viral load of 100,000 copies/mL: 26% (14/54) compared to 74% (40/54) of NNRTI-resistance substitutions and 22% (11/50) compared to 78% (39/50) of NRTI-resistance substitutions. This difference was also observed for the individual emtricitabine/lamivudine and tenofovir resistance substitutions: 23% (11/47) compared to 77% (36/47) for M184I/V and 0% (0/8) compared to 100% (8/8) for K65R/N. Additionally, NNRTI- and NRTI-resistance substitutions emerged less frequently in the resistance analysis of viruses from subjects with baseline CD4+ cell counts >= 200 cells/mm3 compared to viruses from subjects with baseline CD4+ cell counts 200 cells/mm3: 37% (20/54) compared to 63% (34/54) of NNRTI-resistance substitutions and 28% (14/50) compared to 72% (36/50) of NRTI-resistance substitutions.Table 11: Proportion of Resistance Analysis SubjectsSubjects who qualified for resistance analysis. with Frequently Emerging Reverse Transcriptase Substitutions from the Pooled Phase TMC278-C209 and TMC278-C215 Trials in the Week 96 AnalysisC209 and C215N 1368EDURANT BRN 686Efavirenz BRN 682BR background regimenSubjects who Qualified for Resistance Analysis15% (98/652)9% (56/604)Subjects with Evaluable Post-Baseline Resistance Data8743Emerging NNRTI SubstitutionsV90, L100, K101, K103, V106, V108, E138, V179, Y181, Y188, V189, G190, H221, P225, F227 or M230Any62% (54/87)53% (23/43)V90I13% (11/87)2% (1/43)K101E/P/T/Q20% (17/87)9% (4/43)K103N1% (1/87)40% (17/43)E138K/A/Q/G40% (35/87)2% (1/43) E138K+ M184I This combination of NNRTI and NRTI substitutions is subset of those with the E138K. 25% (22/87)0V179I/L/D6% (5/87)7% (3/43)Y181C/I/S10% (9/87)2% (1/43)V189I8% (7/87)2% (1/43)H221Y9% (8/87)0Emerging NRTI SubstitutionsA62V, K65R/N, D67N/G, K70E, L74I, V75I, Y115F, M184I/V, L210F, T215S/T, K219E/R Any57% (50/87)30% (13/43)M184I/V54% (47/87)26% (11/43)K65R/N9% (8/87)5% (2/43)A62V, D67N/G, K70E, Y115F, T215S/T or K219E/RThese substitutions emerged in addition to the primary substitutions M184V/I or K65R/N; A62V (n=3), D67N/G (n=3), K70E (n=4), Y115F (n=2), T215S/T (n=1), K219E/R (n=8) in rilpivirine resistance analysis subjects. 21% (18/87)2% (1/43). Cross-Resistance. Site-Directed NNRTI Mutant VirusCross-resistance has been observed among NNRTIs. The single NNRTI substitutions K101P, Y181I and Y181V conferred 52-fold, 15-fold and 12-fold decreased susceptibility to rilpivirine, respectively. The combination of E138K and M184I showed 6.7-fold reduced susceptibility to rilpivirine compared to 2.8-fold for E138K alone. The K103N substitution did not result in reduced susceptibility to rilpivirine by itself. However, the combination of K103N and L100I resulted in 7-fold reduced susceptibility to rilpivirine. Combinations of or NNRTI resistance-associated substitutions had decreased susceptibility to rilpivirine (fold change range of 3.7 554) in 38% and 66% of mutants analyzed, respectively.. Treatment-Naive HIV-1-Infected Adult SubjectsConsidering all available cell culture and clinical data, any of the following amino acid substitutions, when present at baseline, are likely to decrease the antiviral activity of rilpivirine: K101E, K101P, E138A, E138G, E138K, E138R, E138Q, V179L, Y181C, Y181I, Y181V, Y188L, H221Y, F227C, M230I or M230L.Cross-resistance to efavirenz, etravirine and/or nevirapine is likely after virologic failure and development of rilpivirine resistance. In the Week 96 pooled analyses of the Phase TMC278-C209 and TMC278-C215 clinical trials, 50 of the 87 (57%) rilpivirine resistance analysis subjects with post-baseline resistance data had virus with decreased susceptibility to rilpivirine (>= 2.5-fold change). Of these, 86% (n= 43/50) were resistant to efavirenz (>= 3.3-fold change), 90% (n= 45/50) were resistant to etravirine (>= 3.2-fold change) and 62% (n= 31/50) were resistant to nevirapine (>= 6-fold change). In the efavirenz arm, of the 21 (14%) efavirenz resistance analysis subjects viruses were resistant to etravirine and rilpivirine, and 95% (n= 20/21) were resistant to nevirapine. Virus from subjects experiencing virologic failure on EDURANT developed more NNRTI resistance-associated substitutions conferring more cross-resistance to the NNRTI class and had higher likelihood of cross-resistance to all NNRTIs in the class compared to virus from subjects who failed on efavirenz.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Treatment-Naive Adult Subjects. The evidence of efficacy of EDURANT is based on the analyses of 48- and 96-week data from randomized, double-blinded, active controlled, Phase trials TMC278-C209 (ECHO) and TMC278-C215 (THRIVE) in antiretroviral treatment-naive adults. Antiretroviral treatment-naive HIV-1 infected subjects enrolled in the Phase trials had plasma HIV-1 RNA >= 5000 copies/mL and were screened for susceptibility to N(t)RTIs and for absence of specific NNRTI resistance-associated substitutions (RASs). The Phase trials were identical in design, apart from the background regimen (BR). In TMC278-C209, the BR was fixed to the N(t)RTIs, tenofovir disoproxil fumarate plus emtricitabine. In TMC278-C215, the BR consisted of investigator-selected N(t)RTIs: tenofovir disoproxil fumarate plus emtricitabine or zidovudine plus lamivudine or abacavir plus lamivudine. In both trials, randomization was stratified by screening viral load. In TMC278-C215, randomization was also stratified by N(t)RTI BR.In the pooled analysis for TMC278-C209 and TMC278-C215, demographics and baseline characteristics were balanced between the EDURANT arm and the efavirenz arm. Table 12 displays selected demographic and baseline disease characteristics of the subjects in the EDURANT and efavirenz arms.Table 12: Demographic and Baseline Disease Characteristics of Antiretroviral Treatment-Naive HIV-1-Infected Adult Subjects in the TMC278-C209 and TMC278-C215 Trials (Pooled Analysis)Pooled Data from the Phase TMC278-C209 and TMC278-C215 TrialsEDURANT BRN=686Efavirenz BRN=682BR=background regimenDemographic CharacteristicsMedian Age, years (range)36 (18-78)36 (19-69)Sex Male76%76% Female24%24%Race White61%60% Black/African American24%23% Asian11%14% Other2%2% Not allowed to ask per local regulations1%1%Baseline Disease CharacteristicsMedian Baseline Plasma HIV-1 RNA (range), log10 copies/mL5.0 (2-7)5.0 (3-7)Percentage of Patients with Baseline Plasma Viral Load: <= 100,00054%48% 100,000 to <= 500,00036%40% 500,00010%12%Median Baseline CD4+ Cell Count (range), cells/mm3 249 (1-888)260 (1-1137)Percentage of Subjects with: Hepatitis B/C Virus Co-infection7%10%Percentage of Patients with the Following Background Regimens: tenofovir disoproxil fumarate plus emtricitabine80%80% zidovudine plus lamivudine15%15% abacavir plus lamivudine5%5%Week 96 efficacy outcomes for subjects treated with EDURANT 25 mg once daily from the pooled analysis are shown in Table 13. The incidence of virologic failure was higher in the EDURANT arm than the efavirenz arm at Week 96. Virologic failures and discontinuations due to adverse events mostly occurred in the first 48 weeks of treatment. Regardless of HIV-1 RNA at the start of therapy, more EDURANT treated subjects with CD4+ cell count less than 200 cells/mm3 experienced virologic failure compared to EDURANT treated subjects with CD4+ cell count greater than or equal to 200 cells/mm3.Table 13: Virologic Outcome of Randomized Treatment of Studies TMC278-C209 and TMC278-C215 (Pooled Data) at Week 96EDURANT BRN=686Efavirenz BRN=682N total number of subjects per treatment group; BR background regimen.Note: Analysis was based on the last observed viral load data within the Week 96 window (Week 90-103), respectively.HIV-1 RNA 50 copies/mLCI Predicted difference (95% CI) of response rate is -0.2 (-4.7; 4.3) at Week 96. 76%77%HIV-1 RNA >= 50 copies/mLIncludes subjects who had >= 50 copies/mL in the Week 96 window, subjects who discontinued early due to lack or loss of efficacy, subjects who discontinued for reasons other than an adverse event, death or lack or loss of efficacy and at the time of discontinuation had viral value of >= 50 copies/mL, and subjects who had switch in background regimen that was not permitted by the protocol. 16%10%No virologic data at Week 96 window Reasons Discontinued study due to adverse event or deathIncludes subjects who discontinued due to an adverse event or death if this resulted in no on-treatment virologic data in the Week 96 window. 4%8% Discontinued study for other reasons and last available HIV-1 RNA 50 copies/mL (or missing)Includes subjects who discontinued for reasons other than an adverse event, death or lack or loss of efficacy, e.g., withdrew consent, loss to follow-up, etc. 4%5% Missing data during window but on study< 1%< 1%HIV-1 RNA 50 copies/mL by Baseline HIV-1 RNA (copies/mL) <= 100,00082%78% 100,00070%75%HIV-1 RNA >= 50 copies/mL by Baseline HIV-1 RNA (copies/mL) <= 100,0009%8% 100,00024%11%HIV-1 RNA 50 copies/mL by CD4+ cell count (cells/mm3) 20068%74% >= 20081%77%HIV-1 RNA >= 50 copies/mL by CD4+ cell count (cells/mm3) 20027%10% >= 20010%9%At Week 96, the mean CD4+ cell count increase from baseline was 228 cells/mm3 for EDURANT-treated subjects and 219 cells/mm3 for efavirenz-treated subjects in the pooled analysis of the TMC278-C209 and TMC278-C215 trials.Study TMC278-C204 was randomized, active-controlled, Phase 2b trial in antiretroviral treatment-naive HIV-1-infected adult subjects consisting of parts: an initial 96 weeks, partially-blinded dose-finding part [EDURANT doses blinded] followed by long-term, open-label part. After Week 96, subjects randomized to one of the doses of EDURANT were switched to EDURANT 25 mg once daily. Subjects in the control arm received efavirenz 600 mg once daily in addition to BR in both parts of the study. The BR consisted of investigator-selected N(t)RTIs: zidovudine plus lamivudine or tenofovir disoproxil fumarate plus emtricitabine.Study TMC278-C204 enrolled 368 HIV-1-infected treatment-naive adult subjects who had plasma HIV-1 RNA >= 5000 copies/ml, previously received <= weeks of treatment with an N(t)RTI or protease inhibitor, had no prior use of NNRTIs, and were screened for susceptibility to N(t)RTI and for absence of specific NNRTI RASs.At 96 weeks, the proportion of subjects with <50 HIV-1 RNA copies/mL receiving EDURANT 25 mg (N 93) compared to subjects receiving efavirenz (N 89) was 76% and 71%, respectively. The mean increase from baseline in CD4+ counts was 146 cells/mm3 in subjects receiving EDURANT 25 mg and 160 cells/mm3 in subjects receiving efavirenz.At 240 weeks, 60% (56/93) of subjects who originally received 25 mg once daily achieved HIV RNA 50 copies/mL compared to 57% (51/89) of subjects in the control group.. 14.2Virologically-Suppressed Adults Treated in Combination with Cabotegravir. The use of EDURANT in combination with VOCABRIA (cabotegravir) as an oral lead-in and in patients who miss planned injections with CABENUVA (cabotegravir; rilpivirine) extended-release injectable suspensions was evaluated in two Phase randomized, multicenter, active-controlled, parallel-arm, open-label, non-inferiority trials (Trial 201584: FLAIR [NCT02938520] and Trial 201585: ATLAS [NCT2951052]) in subjects who were virologically suppressed (HIV-1 RNA 50 copies/mL). See full prescribing information for VOCABRIA and CABENUVA for additional information.. 14.3Treatment-Naive Pediatric Subjects (12 to less than 18 years of age). The pharmacokinetics, safety, tolerability and efficacy of EDURANT 25 mg once daily, in combination with an investigator-selected background regimen (BR) containing two NRTIs, was evaluated in trial TMC278-C213, single-arm, open-label Phase trial in antiretroviral treatment-naive HIV-1 infected pediatric subjects 12 to less than 18 years of age and weighing at least 32 kg. Thirty six (36) subjects were enrolled in the trial to complete at least 48 weeks of treatment. The 36 subjects had median age of 14.5 years (range: 12 to 17 years), and were 55.6% female, 88.9% Black and 11.1% Asian.In the efficacy analysis, most subjects (75%; 28/36) had baseline HIV RNA <100,000 copies/mL. For these 28 subjects the median baseline plasma HIV-1 RNA was 44,250 (range: 2,060-92,600 copies/mL) and the median baseline CD4+ cell count was 445.5 cells/mm3 (range: 123 to 983 cells/mm3).Among the subjects who had baseline HIV RNA <= 100,000, the proportion with HIV-1 RNA <50 copies/mL at Week 48 was 79% (22/28), versus 50.0% (4/8) in those with >100,000 copies/mL. The proportion of virologic failures among subjects with baseline viral load <=100,000 copies/mL was 21.4% (6/28), versus 37.5% (3/8) in those with >100,000 copies/mL. At Week 48, the mean increase in CD4+ cell count from baseline was 201.2 cells/mm3.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. [see Dosage and Administration (2), Contraindications (4) and Clinical Pharmacology (12.3).] Rilpivirine is primarily metabolized by cytochrome P450 (CYP)3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of rilpivirine. Coadministration of EDURANT and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs. Coadministration of EDURANT and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of EDURANT with drugs that increase gastric pH may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs.EDURANT at dose of 25 mg once daily is not likely to have clinically relevant effect on the exposure of drugs metabolized by CYP enzymes.Table shows the established and other potentially significant drug interactions based on which alterations in dose or regimen of EDURANT and/or coadministered drug may be recommended. Drugs that are not recommended for coadministration with EDURANT are also included in Table 5.Table 5: Established and Other Potentially Significant Drug Interactions: Alterations in Dose or Regimen May Be Recommended Based on Drug Interaction Studies or Predicted Interaction [see Clinical Pharmacology (12.3)]Concomitant Drug Class: Drug NameEffect on Concentration of Rilpivirine or Concomitant Drug Clinical Comment increase, decrease, <-> no change Antacids:antacids (e.g., aluminum or magnesium hydroxide, calcium carbonate)<-> rilpivirine (antacids taken at least hours before or at least hours after rilpivirine)The combination of EDURANT and antacids should be used with caution as coadministration may cause significant decreases in rilpivirine plasma concentrations (increase in gastric pH).

Rilpivirine did not have clinically significant effect on the pharmacokinetics of digoxin or metformin. No clinically relevant drug-drug interaction is expected when EDURANT is coadministered with maraviroc, ribavirin or the NRTIs abacavir, emtricitabine, lamivudine, stavudine and zidovudine.. Consider alternatives to EDURANT when coadministered with drugs with known risk of torsade de pointes. (5.4) EDURANT should not be used in combination with NNRTIs.

QT Prolonging DrugsThere is limited information available on the potential for pharmacodynamic interaction between rilpivirine and drugs that prolong the QTc interval of the electrocardiogram. In study of healthy subjects, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram [see Clinical Pharmacology (12.2)]. Consider alternatives to EDURANT when coadministered with drug with known risk of torsade de pointes.

MICROBIOLOGY SECTION.

12.4 Microbiology. Mechanism of ActionRilpivirine is diarylpyrimidine non-nucleoside reverse transcriptase inhibitor (NNRTI) of human immunodeficiency virus type (HIV-1) and inhibits HIV-1 replication by non-competitive inhibition of HIV-1 reverse transcriptase (RT). Rilpivirine does not inhibit the human cellular DNA polymerases and .. Antiviral Activity in Cell CultureRilpivirine exhibited activity against laboratory strains of wild-type HIV-1 in an acutely infected T-cell line with median EC50 value for HIV-1IIIB of 0.73 nM (0.27 ng/mL). Rilpivirine demonstrated limited activity in cell culture against HIV-2 with median EC50 value of 5220 nM (range 2510 to 10830 nM) (920 to 3970 ng/mL).Rilpivirine demonstrated antiviral activity against broad panel of HIV-1 group (subtype A, B, C, D, F, G, H) primary isolates with EC50 values ranging from 0.07 to 1.01 nM (0.03 to 0.37 ng/mL) and was less active against group primary isolates with EC50 values ranging from 2.88 to 8.45 nM (1.06 to 3.10 ng/mL).The antiviral activity of rilpivirine was not antagonistic when combined with the NNRTIs efavirenz, etravirine or nevirapine; the N(t)RTIs abacavir, didanosine, emtricitabine, lamivudine, stavudine, tenofovir or zidovudine; the PIs amprenavir, atazanavir, darunavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir or tipranavir; the fusion inhibitor enfuvirtide; the CCR5 co-receptor antagonist maraviroc, or the integrase strand transfer inhibitor raltegravir.. Resistance. In Cell CultureRilpivirine-resistant strains were selected in cell culture starting from wild-type HIV-1 of different origins and subtypes as well as NNRTI resistant HIV-1. The frequently observed amino acid substitutions that emerged and conferred decreased phenotypic susceptibility to rilpivirine included: L100I, K101E, V106I and A, V108I, E138K and G, Q, R, V179F and I, Y181C and I, V189I, G190E, H221Y, F227C and M230I and L.. In Treatment-Naive Adult SubjectsIn the Week 96 pooled resistance analysis of the Phase trials C209 and C215, the emergence of resistance was greater among subjects viruses in the EDURANT arm compared to the efavirenz arm, and was dependent on baseline viral load. In the pooled resistance analysis, 58% (57/98) of the subjects who qualified for resistance analysis (resistance analysis subjects) in the EDURANT arm had virus with genotypic and/or phenotypic resistance to rilpivirine compared to 45% (25/56) of the resistance analysis subjects in the efavirenz arm who had genotypic and/or phenotypic resistance to efavirenz. Moreover, genotypic and/or phenotypic resistance to background drug (emtricitabine, lamivudine, tenofovir, abacavir or zidovudine) emerged in viruses from 52% (51/98) of the resistance analysis subjects in the rilpivirine arm compared to 23% (13/56) in the efavirenz arm.Emerging NNRTI substitutions in the rilpivirine resistance analysis of subjects viruses included V90I, K101E/P/T, E138K/A/Q/G, V179I/L, Y181C/I, V189I, H221Y, F227C/L and M230L, which were associated with rilpivirine phenotypic fold change range of 2.6 621. The E138K substitution emerged most frequently during rilpivirine treatment commonly in combination with the M184I substitution. The emtricitabine and lamivudine resistance-associated substitutions M184I or and NRTI resistance-associated substitutions (K65R/N, A62V, D67N/G, K70E, Y115F, T215S/T, or K219E/R) emerged more frequently in rilpivirine resistance analysis subjects compared to efavirenz resistance analysis subjects (see Table 11).NNRTI- and NRTI-resistance substitutions emerged less frequently in resistance analysis of viruses from subjects with baseline viral load of <= 100,000 copies/mL compared to viruses from subjects with baseline viral load of 100,000 copies/mL: 26% (14/54) compared to 74% (40/54) of NNRTI-resistance substitutions and 22% (11/50) compared to 78% (39/50) of NRTI-resistance substitutions. This difference was also observed for the individual emtricitabine/lamivudine and tenofovir resistance substitutions: 23% (11/47) compared to 77% (36/47) for M184I/V and 0% (0/8) compared to 100% (8/8) for K65R/N. Additionally, NNRTI- and NRTI-resistance substitutions emerged less frequently in the resistance analysis of viruses from subjects with baseline CD4+ cell counts >= 200 cells/mm3 compared to viruses from subjects with baseline CD4+ cell counts 200 cells/mm3: 37% (20/54) compared to 63% (34/54) of NNRTI-resistance substitutions and 28% (14/50) compared to 72% (36/50) of NRTI-resistance substitutions.Table 11: Proportion of Resistance Analysis SubjectsSubjects who qualified for resistance analysis. with Frequently Emerging Reverse Transcriptase Substitutions from the Pooled Phase TMC278-C209 and TMC278-C215 Trials in the Week 96 AnalysisC209 and C215N 1368EDURANT BRN 686Efavirenz BRN 682BR background regimenSubjects who Qualified for Resistance Analysis15% (98/652)9% (56/604)Subjects with Evaluable Post-Baseline Resistance Data8743Emerging NNRTI SubstitutionsV90, L100, K101, K103, V106, V108, E138, V179, Y181, Y188, V189, G190, H221, P225, F227 or M230Any62% (54/87)53% (23/43)V90I13% (11/87)2% (1/43)K101E/P/T/Q20% (17/87)9% (4/43)K103N1% (1/87)40% (17/43)E138K/A/Q/G40% (35/87)2% (1/43) E138K+ M184I This combination of NNRTI and NRTI substitutions is subset of those with the E138K. 25% (22/87)0V179I/L/D6% (5/87)7% (3/43)Y181C/I/S10% (9/87)2% (1/43)V189I8% (7/87)2% (1/43)H221Y9% (8/87)0Emerging NRTI SubstitutionsA62V, K65R/N, D67N/G, K70E, L74I, V75I, Y115F, M184I/V, L210F, T215S/T, K219E/R Any57% (50/87)30% (13/43)M184I/V54% (47/87)26% (11/43)K65R/N9% (8/87)5% (2/43)A62V, D67N/G, K70E, Y115F, T215S/T or K219E/RThese substitutions emerged in addition to the primary substitutions M184V/I or K65R/N; A62V (n=3), D67N/G (n=3), K70E (n=4), Y115F (n=2), T215S/T (n=1), K219E/R (n=8) in rilpivirine resistance analysis subjects. 21% (18/87)2% (1/43). Cross-Resistance. Site-Directed NNRTI Mutant VirusCross-resistance has been observed among NNRTIs. The single NNRTI substitutions K101P, Y181I and Y181V conferred 52-fold, 15-fold and 12-fold decreased susceptibility to rilpivirine, respectively. The combination of E138K and M184I showed 6.7-fold reduced susceptibility to rilpivirine compared to 2.8-fold for E138K alone. The K103N substitution did not result in reduced susceptibility to rilpivirine by itself. However, the combination of K103N and L100I resulted in 7-fold reduced susceptibility to rilpivirine. Combinations of or NNRTI resistance-associated substitutions had decreased susceptibility to rilpivirine (fold change range of 3.7 554) in 38% and 66% of mutants analyzed, respectively.. Treatment-Naive HIV-1-Infected Adult SubjectsConsidering all available cell culture and clinical data, any of the following amino acid substitutions, when present at baseline, are likely to decrease the antiviral activity of rilpivirine: K101E, K101P, E138A, E138G, E138K, E138R, E138Q, V179L, Y181C, Y181I, Y181V, Y188L, H221Y, F227C, M230I or M230L.Cross-resistance to efavirenz, etravirine and/or nevirapine is likely after virologic failure and development of rilpivirine resistance. In the Week 96 pooled analyses of the Phase TMC278-C209 and TMC278-C215 clinical trials, 50 of the 87 (57%) rilpivirine resistance analysis subjects with post-baseline resistance data had virus with decreased susceptibility to rilpivirine (>= 2.5-fold change). Of these, 86% (n= 43/50) were resistant to efavirenz (>= 3.3-fold change), 90% (n= 45/50) were resistant to etravirine (>= 3.2-fold change) and 62% (n= 31/50) were resistant to nevirapine (>= 6-fold change). In the efavirenz arm, of the 21 (14%) efavirenz resistance analysis subjects viruses were resistant to etravirine and rilpivirine, and 95% (n= 20/21) were resistant to nevirapine. Virus from subjects experiencing virologic failure on EDURANT developed more NNRTI resistance-associated substitutions conferring more cross-resistance to the NNRTI class and had higher likelihood of cross-resistance to all NNRTIs in the class compared to virus from subjects who failed on efavirenz.

PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Pharmacokinetics in AdultsThe pharmacokinetic properties of rilpivirine have been evaluated in adult healthy subjects and in adult antiretroviral treatment-naive HIV-1-infected subjects. Exposure to rilpivirine was generally lower in HIV-1 infected subjects than in healthy subjects.Table 6: Population Pharmacokinetic Estimates of Rilpivirine 25 mg once daily in Antiretroviral Treatment-Naive HIV-1-Infected Adult Subjects (Pooled Data from Phase Trials through Week 96)ParameterRilpivirine 25 mg once dailyN 679AUC24h (ngh/mL) Mean +- Standard Deviation2235 +- 851 Median (Range)2096 (198 7307)C0h (ng/mL) Mean +- Standard Deviation79 +- 35 Median (Range)73 (2 288). Absorption and BioavailabilityAfter oral administration, the maximum plasma concentration of rilpivirine is generally achieved within 4-5 hours. The absolute bioavailability of EDURANT is unknown.. Effects of Food on Oral AbsorptionThe exposure to rilpivirine was approximately 40% lower when EDURANT was taken in fasted condition as compared to normal caloric meal (533 kcal) or high-fat high-caloric meal (928 kcal). When EDURANT was taken with only protein-rich nutritional drink, exposures were 50% lower than when taken with meal.. DistributionRilpivirine is approximately 99.7% bound to plasma proteins in vitro, primarily to albumin. The distribution of rilpivirine into compartments other than plasma (e.g., cerebrospinal fluid, genital tract secretions) has not been evaluated in humans.. MetabolismIn vitro experiments indicate that rilpivirine primarily undergoes oxidative metabolism mediated by the cytochrome P450 (CYP) 3A system.. EliminationThe terminal elimination half-life of rilpivirine is approximately 50 hours. After single dose oral administration of 14C-rilpivirine, on average 85% and 6.1% of the radioactivity could be retrieved in feces and urine, respectively. In feces, unchanged rilpivirine accounted for on average 25% of the administered dose. Only trace amounts of unchanged rilpivirine (< 1% of dose) were detected in urine.. Special Populations. Pregnancy and PostpartumThe exposure (C0h and AUC24h) to total rilpivirine after intake of rilpivirine 25 mg once daily as part of an antiretroviral regimen was 30 to 40% lower during pregnancy (similar for the second and third trimester), compared with postpartum (see Table 7). However, the exposure during pregnancy was not significantly different from exposures obtained in Phase trials. Based on the exposure-response relationship for rilpivirine, this decrease is not considered clinically relevant in patients who are virollogically suppressed. The protein binding of rilpivirine was similar (>99%) during the second trimester, third trimester, and postpartum.Table 7:Pharmacokinetic Results of Total Rilpivirine After Administration of Rilpivirine 25 mg Once Daily as Part of an Antiretroviral Regimen, During the 2nd Trimester of Pregnancy, the 3rd Trimester of Pregnancy and PostpartumPharmacokinetics of total rilpivirine(mean +- SD, tmax: median [range])Postpartum(6-12 Weeks)(n=11)2nd Trimester of pregnancy(n=15)3rd Trimester of pregnancy(n=13)C0h, ng/mL111 +- 69.265.0 +- 23.963.5 +- 26.2Cmin, ng/mL84.0 +- 58.854.3 +- 25.852.9 +- 24.4Cmax, ng/mL167 +- 101121 +-45.9123 +- 47.5tmax, h4.00 (2.03-25.08)4.00 (1.00-9.00)4.00 (2.00-24.93)AUC24h, ng.h/mL2714 +- 15351792 +- 7111762 +- 662. Pediatric PatientsThe pharmacokinetics of rilpivirine in antiretroviral treatment-naive HIV-1 infected pediatric subjects 12 to less than 18 years of age receiving EDURANT 25 mg once daily were comparable to those in treatment-naive HIV-1 infected adults receiving EDURANT 25 mg once daily. There was no clinically significant impact of body weight on rilpivirine pharmacokinetics in pediatric subjects in trial C213 (33 to 93 kg).Table 8:Population Pharmacokinetic Estimates of Rilpivirine 25 mg once daily in Antiretroviral Treatment-Naive HIV-1-Infected Pediatric Subjects aged 12 to less than 18 years (Data from Phase Trial through Week 48)ParameterRilpivirine 25 mg once dailyN 34AUC24h (ngh/mL) Mean +- Standard Deviation2424 +- 1024 Median (Range)2269 (417 5166)C0h (ng/mL) Mean +- Standard Deviation85 +- 40 Median (Range)79 (7 202)The pharmacokinetics and dosing recommendations of rilpivirine in pediatric patients who are less than 12 years of age and less than 35 kg have not been established [see Use in Specific Populations (8.4)].. Renal ImpairmentPopulation pharmacokinetic analysis indicated that rilpivirine exposure was similar in HIV-1 infected subjects with mild renal impairment relative to HIV-1 infected subjects with normal renal function. No dose adjustment is required in patients with mild renal impairment. There is limited or no information regarding the pharmacokinetics of rilpivirine in patients with moderate or severe renal impairment or in patients with end-stage renal disease, and rilpivirine concentrations may be increased due to alteration of drug absorption, distribution, and metabolism secondary to renal dysfunction. The potential impact is not expected to be of clinical relevance for HIV-1-infected subjects with moderate renal impairment, and no dose adjustment is required in these patients. Rilpivirine should be used with caution and with increased monitoring for adverse effects in patients with severe renal impairment or end-stage renal disease. As rilpivirine is highly bound to plasma proteins, it is unlikely that it will be significantly removed by hemodialysis or peritoneal dialysis [see Use in Specific Populations (8.6)].. Hepatic ImpairmentRilpivirine is primarily metabolized and eliminated by the liver. In study comparing subjects with mild hepatic impairment (Child-Pugh score A) to matched controls, and subjects with moderate hepatic impairment (Child-Pugh score B) to matched controls, the multiple dose exposure of rilpivirine was 47% higher in subjects with mild hepatic impairment and 5% higher in subjects with moderate hepatic impairment. EDURANT has not been studied in subjects with severe hepatic impairment (Child-Pugh score C) [see Use in Specific Populations (8.7)].. Gender, Race, Hepatitis and/or Hepatitis Virus Co-infectionNo clinically relevant differences in the pharmacokinetics of rilpivirine have been observed between gender, race and patients with hepatitis and/or C-virus co-infection.. Drug Interactions[see Contraindications (4) and Drug Interactions (7).] Rilpivirine is primarily metabolized by cytochrome P450 (CYP)3A, and drugs that induce or inhibit CYP3A may thus affect the clearance of rilpivirine. Coadministration of EDURANT and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance. Coadministration of EDURANT and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of EDURANT with drugs that increase gastric pH may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine and to the class of NNRTIs.EDURANT at dose of 25 mg once daily is not likely to have clinically relevant effect on the exposure of medicinal products metabolized by CYP enzymes.Drug interaction studies were performed with EDURANT and other drugs likely to be coadministered or commonly used as probes for pharmacokinetic interactions. The effects of coadministration of other drugs on the Cmax, AUC, and Cmin values of rilpivirine are summarized in Table (effect of other drugs on EDURANT). The effect of coadministration of EDURANT on the Cmax, AUC, and Cmin values of other drugs are summarized in Table 10 (effect of EDURANT on other drugs).

PREGNANCY SECTION.

8.1 Pregnancy. Pregnancy Exposure RegistryThere is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EDURANT during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) 1-800-258-4263.. Risk SummaryAvailable data from the APR show no difference in the overall risk of birth defects for rilpivirine compared with the background rate for major birth defects of 2.7% in the Metropolitan Atlanta Congenital Defects Program (MACDP) reference population (see Data). The rate of miscarriage is not reported in the APR. The estimated background rate of miscarriage in clinically recognized pregnancies in the U.S. general population is 15% to 20%. The background risk for major birth defects and miscarriage for the indicated population is unknown. Methodologic limitations of the APR include the use of MACDP as the external comparator group. The MACDP population is not disease-specific, evaluates women and infants from limited geographic area, and does not include outcomes for births that occurred at <20 weeks gestation. In clinical trial, total rilpivirine exposures were generally lower during pregnancy compared to the postpartum period (see Data). In animal reproduction studies, no adverse developmental outcomes were observed when rilpivirine was administered orally at exposures up to 15 (rats) and 70 (rabbits) times the exposure in humans at the recommended dose of 25 mg once daily (see Data).. Clinical Considerations. Dose Adjustments During Pregnancy and the Postpartum PeriodBased on the experience of HIV-1-infected pregnant women who completed clinical trial through the postpartum period with rilpivirine-based regimen, no dose adjustments are required for pregnant patients who are already on stable EDURANT regimen prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL). The recommended dosage is one 25 mg tablet once daily taken orally with meal. Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely [see Clinical Pharmacology (12.3)]. Data. Human DataBased on prospective reports to the APR of over 390 exposures to rilpivirine during the first trimester of pregnancy resulting in live births, there was no significant difference between the overall risk of birth defects with rilpivirine compared to the background birth defect rate of 2.7% in the U.S. reference population of the MACDP. The prevalence of birth defects in live births was 1.3% (95% CI: 0.4% to 3.0%) and 1.1% (95% CI: 0.1% to 4.0%) following first and second/third trimester exposure, respectively, to rilpivirine-containing regimens.Rilpivirine in combination with background regimen was evaluated in clinical trial of 19 HIV-1 infected pregnant women during the second and third trimesters and postpartum. Each of the women were on rilpivirine-based regimen at the time of enrollment. Twelve subjects completed the trial through the postpartum period (6-12 weeks after delivery) and pregnancy outcomes are missing for six subjects. The exposure (C0h and AUC) of total rilpivirine was approximately 30 to 40% lower during pregnancy compared with postpartum (6 to 12 weeks). The protein binding of rilpivirine was similar (>99%) during second trimester, third trimester, and postpartum period. One subject discontinued the trial following spontaneous termination of the pregnancy at 25 weeks gestation due to suspected premature rupture of membranes. Among the 12 subjects who were virologically suppressed at baseline (less than 50 copies/mL), virologic response was preserved in 10 subjects (83.3%) through the third trimester visit and in subjects (75%) through the 6-12 week postpartum visit. Virologic outcomes during the third trimester visit were missing for two subjects who were withdrawn (one subject was nonadherent to the study drug and one subject withdrew consent). Among the 10 infants with HIV test results available, born to 10 HIV-infected pregnant women, all had test results that were negative for HIV-1 at the time of delivery and up to 16 weeks postpartum. All 10 infants received antiretroviral prophylactic treatment with zidovudine. Rilpivirine was well tolerated during pregnancy and postpartum. There were no new safety findings compared with the known safety profile of rilpivirine in HIV-1-infected adults.. Animal DataRilpivirine was administered orally to pregnant rats (40, 120, or 400 mg per kg per day) and rabbits (5, 10, or 20 mg per kg per day) through organogenesis (on gestation Days through 17, and through 19, respectively). No significant toxicological effects were observed in embryo-fetal toxicity studies performed with rilpivirine in rats and rabbits at exposures 15 (rats) and 70 (rabbits) times higher than the exposure in humans at the recommended dose of 25 mg once daily. In pre- and postnatal development study, rilpivirine was administered orally up to 400 mg/kg/day through lactation. No adverse effects were noted in the offspring at maternal exposures up to 63 times the exposure in humans at the recommended dose of 25 mg daily.

Liver Problems. People with history of hepatitis or virus infection or who have certain liver function test changes may have an increased risk of developing new or worsening changes in certain liver tests during treatment with EDURANT. Liver problems have also happened in people without history of problems or other risk factors. Your healthcare provider may need to do tests to check your liver function before and during treatment with EDURANT. Call your healthcare provider right away if you develop any of the following signs or symptoms of liver problems: your skin or the white part of your eyes turns yellow (jaundice)light colored stools (bowel movements)pain, aching, or tenderness on the right side of the stomach arealoss of appetitedark or tea colored urinenausea or vomiting your skin or the white part of your eyes turns yellow (jaundice). light colored stools (bowel movements). pain, aching, or tenderness on the right side of the stomach area. loss of appetite. dark or tea colored urine. nausea or vomiting Depression or mood changes. Call your healthcare provider right away if you have any of the following symptoms:feeling sad or hopelessfeeling anxious or restlesshave thoughts of hurting yourself (suicide) or have tried to hurt yourself. feeling sad or hopeless. feeling anxious or restless. have thoughts of hurting yourself (suicide) or have tried to hurt yourself. Changes in body fat can happen in people who take HIV medicine. These changes may include increased amount of fat in the upper back and neck (buffalo hump), breast, and around the middle of your body (trunk). Loss of fat from the legs, arms, and face may also happen. The exact cause and long- term health effects of these problems are not known.. Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for long time. Tell your healthcare provider right away if you start having any new symptoms after starting your HIV-1 medicine.. Store EDURANT at room temperature between 68F to 77F (20C to 25C).. Keep EDURANT in the original bottle to protect from light.

USE IN SPECIFIC POPULATIONS SECTION.

8 USE IN SPECIFIC POPULATIONS. Pregnancy: Total rilpivirine exposures were generally lower during pregnancy compared to the postpartum period. (2.1, 8.1, 12.3)Lactation: Women infected with HIV should be instructed not to breastfeed due to the potential for HIV transmission. (8.2). Pregnancy: Total rilpivirine exposures were generally lower during pregnancy compared to the postpartum period. (2.1, 8.1, 12.3). Lactation: Women infected with HIV should be instructed not to breastfeed due to the potential for HIV transmission. (8.2). 8.1 Pregnancy. Pregnancy Exposure RegistryThere is pregnancy exposure registry that monitors pregnancy outcomes in women exposed to EDURANT during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) 1-800-258-4263.. Risk SummaryAvailable data from the APR show no difference in the overall risk of birth defects for rilpivirine compared with the background rate for major birth defects of 2.7% in the Metropolitan Atlanta Congenital Defects Program (MACDP) reference population (see Data). The rate of miscarriage is not reported in the APR. The estimated background rate of miscarriage in clinically recognized pregnancies in the U.S. general population is 15% to 20%. The background risk for major birth defects and miscarriage for the indicated population is unknown. Methodologic limitations of the APR include the use of MACDP as the external comparator group. The MACDP population is not disease-specific, evaluates women and infants from limited geographic area, and does not include outcomes for births that occurred at <20 weeks gestation. In clinical trial, total rilpivirine exposures were generally lower during pregnancy compared to the postpartum period (see Data). In animal reproduction studies, no adverse developmental outcomes were observed when rilpivirine was administered orally at exposures up to 15 (rats) and 70 (rabbits) times the exposure in humans at the recommended dose of 25 mg once daily (see Data).. Clinical Considerations. Dose Adjustments During Pregnancy and the Postpartum PeriodBased on the experience of HIV-1-infected pregnant women who completed clinical trial through the postpartum period with rilpivirine-based regimen, no dose adjustments are required for pregnant patients who are already on stable EDURANT regimen prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL). The recommended dosage is one 25 mg tablet once daily taken orally with meal. Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely [see Clinical Pharmacology (12.3)]. Data. Human DataBased on prospective reports to the APR of over 390 exposures to rilpivirine during the first trimester of pregnancy resulting in live births, there was no significant difference between the overall risk of birth defects with rilpivirine compared to the background birth defect rate of 2.7% in the U.S. reference population of the MACDP. The prevalence of birth defects in live births was 1.3% (95% CI: 0.4% to 3.0%) and 1.1% (95% CI: 0.1% to 4.0%) following first and second/third trimester exposure, respectively, to rilpivirine-containing regimens.Rilpivirine in combination with background regimen was evaluated in clinical trial of 19 HIV-1 infected pregnant women during the second and third trimesters and postpartum. Each of the women were on rilpivirine-based regimen at the time of enrollment. Twelve subjects completed the trial through the postpartum period (6-12 weeks after delivery) and pregnancy outcomes are missing for six subjects. The exposure (C0h and AUC) of total rilpivirine was approximately 30 to 40% lower during pregnancy compared with postpartum (6 to 12 weeks). The protein binding of rilpivirine was similar (>99%) during second trimester, third trimester, and postpartum period. One subject discontinued the trial following spontaneous termination of the pregnancy at 25 weeks gestation due to suspected premature rupture of membranes. Among the 12 subjects who were virologically suppressed at baseline (less than 50 copies/mL), virologic response was preserved in 10 subjects (83.3%) through the third trimester visit and in subjects (75%) through the 6-12 week postpartum visit. Virologic outcomes during the third trimester visit were missing for two subjects who were withdrawn (one subject was nonadherent to the study drug and one subject withdrew consent). Among the 10 infants with HIV test results available, born to 10 HIV-infected pregnant women, all had test results that were negative for HIV-1 at the time of delivery and up to 16 weeks postpartum. All 10 infants received antiretroviral prophylactic treatment with zidovudine. Rilpivirine was well tolerated during pregnancy and postpartum. There were no new safety findings compared with the known safety profile of rilpivirine in HIV-1-infected adults.. Animal DataRilpivirine was administered orally to pregnant rats (40, 120, or 400 mg per kg per day) and rabbits (5, 10, or 20 mg per kg per day) through organogenesis (on gestation Days through 17, and through 19, respectively). No significant toxicological effects were observed in embryo-fetal toxicity studies performed with rilpivirine in rats and rabbits at exposures 15 (rats) and 70 (rabbits) times higher than the exposure in humans at the recommended dose of 25 mg once daily. In pre- and postnatal development study, rilpivirine was administered orally up to 400 mg/kg/day through lactation. No adverse effects were noted in the offspring at maternal exposures up to 63 times the exposure in humans at the recommended dose of 25 mg daily.. 8.2Lactation. Risk SummaryThe Centers for Disease Control and Prevention recommend that HIV-infected mothers not breastfeed their infants to avoid risking postnatal transmission of HIV. There are no data on the presence of rilpivirine in human milk, the effects on breastfed infant, or the effects on milk production. Rilpivirine is present in rat milk (see Data). Because of the potential for (1) HIV transmission (in HIV-negative infants), (2) developing viral resistance (in HIV-positive infants), and (3) adverse reactions in nursing infants, mothers should not breastfeed if they are receiving EDURANT.. Data. Animal DataAnimal lactation studies with rilpivirine have not been conducted. However, rilpivirine was detected in the plasma of nursing pups on lactation day in the rat pre- and postnatal development study.. 8.4 Pediatric Use. The safety, efficacy and pharmacokinetics of EDURANT were evaluated in single arm, open-label, Phase trial that enrolled 36 antiretroviral treatment-naive, HIV-1 infected pediatric subjects 12 to less than 18 years of age and weighing at least 32 kg [see Dosage and Administration (2.1), Adverse Reactions (6.2), Clinical Pharmacology (12.3) and Clinical Studies (14.3)].Safety and effectiveness in pediatric patients less than 12 years of age or weighing less than 35 kg have not been established.. 8.5 Geriatric Use. Clinical studies of EDURANT did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, caution should be exercised in the administration and monitoring of EDURANT in elderly patients reflecting the greater frequency of decreased renal and hepatic function, and of concomitant disease or other drug therapy.. 8.6 Renal Impairment. No dose adjustment is required in patients with mild or moderate renal impairment. However, in patients with severe renal impairment or end-stage renal disease, rilpivirine should be used with caution and with increased monitoring for adverse effects, as rilpivirine concentrations may be increased due to alteration of drug absorption, distribution, and metabolism secondary to renal dysfunction. As rilpivirine is highly bound to plasma proteins, it is unlikely that it will be significantly removed by hemodialysis or peritoneal dialysis [see Clinical Pharmacology (12.3)].. 8.7Hepatic Impairment. No dosage adjustment of EDURANT is required in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment. EDURANT has not been studied in patients with severe hepatic impairment (Child-Pugh Class C) [see Clinical Pharmacology (12.3)].

WARNINGS AND PRECAUTIONS SECTION.

5 WARNINGS AND PRECAUTIONS. Skin and Hypersensitivity Reactions: Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. Immediately discontinue treatment if hypersensitivity or rash with systemic symptoms or elevations in hepatic serum biochemistries develop and closely monitor clinical status, including hepatic serum biochemistries. (5.1) Hepatotoxicity: Hepatic adverse events have been reported in patients with underlying liver disease, including hepatitis or virus co-infection, or in patients with elevated baseline transaminases. few cases of hepatotoxicity have occurred in patients with no pre-existing hepatic disease. Monitor liver function tests before and during treatment with EDURANT in patients with underlying hepatic disease, such as hepatitis or virus co-infection, or marked elevations in transaminase. Also consider monitoring liver functions tests in patients without pre-existing hepatic dysfunction or other risk factors. (5.2)Depressive Disorders: Severe depressive disorders have been reported. Immediate medical evaluation is recommended for severe depressive disorders. (5.3) Patients may develop redistribution/accumulation of body fat (5.5) or immune reconstitution syndrome. (5.6). Skin and Hypersensitivity Reactions: Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. Immediately discontinue treatment if hypersensitivity or rash with systemic symptoms or elevations in hepatic serum biochemistries develop and closely monitor clinical status, including hepatic serum biochemistries. (5.1). Hepatotoxicity: Hepatic adverse events have been reported in patients with underlying liver disease, including hepatitis or virus co-infection, or in patients with elevated baseline transaminases. few cases of hepatotoxicity have occurred in patients with no pre-existing hepatic disease. Monitor liver function tests before and during treatment with EDURANT in patients with underlying hepatic disease, such as hepatitis or virus co-infection, or marked elevations in transaminase. Also consider monitoring liver functions tests in patients without pre-existing hepatic dysfunction or other risk factors. (5.2). Depressive Disorders: Severe depressive disorders have been reported. Immediate medical evaluation is recommended for severe depressive disorders. (5.3). Patients may develop redistribution/accumulation of body fat (5.5) or immune reconstitution syndrome. (5.6). 5.1 Skin and Hypersensitivity Reactions. Severe skin and hypersensitivity reactions have been reported during the postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. While some skin reactions were accompanied by constitutional symptoms such as fever, other skin reactions were associated with organ dysfunctions, including elevations in hepatic serum biochemistries. During the Phase clinical trials, treatment-related rashes with at least Grade severity were reported in 3% of subjects receiving EDURANT. No Grade rash was reported. Overall, most rashes were Grade or and occurred in the first four to six weeks of therapy [see Adverse Reactions (6 and 6.2)]. Discontinue EDURANT immediately if signs or symptoms of severe skin or hypersensitivity reactions develop, including but not limited to, severe rash or rash accompanied by fever, blisters, mucosal involvement, conjunctivitis, facial edema, angioedema, hepatitis or eosinophilia. Clinical status including laboratory parameters should be monitored and appropriate therapy should be initiated.. 5.2Hepatotoxicity. Hepatic adverse events have been reported in patients receiving rilpivirine-containing regimen. Patients with underlying hepatitis or virus infection, or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations with use of EDURANT. few cases of hepatic toxicity have been reported in adult patients receiving rilpivirine-containing regimen who had no pre-existing hepatic disease or other identifiable risk factors. Appropriate laboratory testing prior to initiating therapy and monitoring for hepatotoxicity during therapy with EDURANT is recommended in patients with underlying hepatic disease such as hepatitis or virus infection, or in patients with marked elevations in transaminases prior to treatment initiation. Liver enzyme monitoring should also be considered for patients without pre-existing hepatic dysfunction or other risk factors.. 5.3Depressive Disorders. The adverse reaction depressive disorders (depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, suicidal ideation) has been reported with EDURANT. Patients with severe depressive symptoms should seek immediate medical evaluation to assess the possibility that the symptoms are related to EDURANT, and if so, to determine whether the risks of continued therapy outweigh the benefits.During the Phase trials in adults (N 1368) through 96 weeks, the incidence of depressive disorders (regardless of causality, severity) reported among EDURANT (n 686) or efavirenz (n 682) was 9% and 8%, respectively. Most events were mild or moderate in severity. The incidence of Grade and depressive disorders (regardless of causality) was 1% for both EDURANT and efavirenz. The incidence of discontinuation due to depressive disorders among EDURANT or efavirenz was 1% in each arm. Suicidal ideation was reported in subjects in each arm while suicide attempt was reported in subjects in the EDURANT arm.During the Phase trial in pediatric subjects 12 to less than 18 years of age (N 36) receiving EDURANT through 48 weeks, the incidence of depressive disorders (regardless of causality, severity) was 19.4% (7/36). Most events were mild or moderate in severity. The incidence of Grade and depressive disorders (regardless of causality) was 5.6% (2/36). None of the subjects discontinued due to depressive disorders. Suicidal ideation and suicide attempt were reported in subject.. 5.4Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions. The concomitant use of EDURANT and other drugs may result in potentially significant drug interactions, some of which may lead to [see Dosage and Administration (2.3), Contraindications (4), and Drug Interactions (7)]:Loss of therapeutic effect of EDURANT and possible development of resistance.In healthy subjects, 75 mg once daily and 300 mg once daily (3 times and 12 times the dose in EDURANT) have been shown to prolong the QTc interval of the electrocardiogram. Consider alternatives to EDURANT when coadministered with drug that is known to have risk of torsade de pointes [see Drug Interactions (7) and Clinical Pharmacology (12.2)].See Table for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during EDURANT therapy and review concomitant medications during EDURANT therapy.. Loss of therapeutic effect of EDURANT and possible development of resistance.. 5.5Fat Redistribution. Redistribution/accumulation of body fat, including central obesity, dorsocervical fat enlargement (buffalo hump), peripheral wasting, facial wasting, breast enlargement, and cushingoid appearance have been observed in patients receiving antiretroviral therapy. The mechanism and long-term consequences of these events are currently unknown. causal relationship has not been established.. 5.6Immune Reconstitution Syndrome. Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including EDURANT. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections (such as Mycobacterium avium infection, cytomegalovirus, Pneumocystis jirovecii pneumonia or tuberculosis), which may necessitate further evaluation and treatment.Autoimmune disorders (such as Graves disease, polymyositis, Guillain-Barre syndrome, and autoimmune hepatitis) have also been reported to occur in the setting of immune reconstitution; however, the time to onset is more variable, and can occur many months after initiation of treatment.
