Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.The safety assessment is based on all data from 1203 subjects in the Phase placebo-controlled trials, TMC125-C206 and TMC125-C216, conducted in antiretroviral treatment-experienced HIV-1-infected adult subjects, 599 of whom received INTELENCE(R) (200 mg b.i.d.). In these pooled trials, the median exposure for subjects in the INTELENCE(R) arm and placebo arm was 52.3 and 51.0 weeks, respectively. Discontinuations due to adverse drug reactions (ADRs) were 5.2% in the INTELENCE(R) arm and 2.6% in the placebo arm.The most frequently reported ADR at least Grade in severity was rash (10.0%). Stevens-Johnson syndrome, drug hypersensitivity reaction and erythema multiforme were reported in 0.1% of subjects during clinical development with INTELENCE(R) [see Warnings and Precautions (5.1) ]. total of 2.2% of HIV-1-infected subjects in Phase trials receiving INTELENCE(R) discontinued due to rash. In general, in clinical trials, rash was mild to moderate, occurred primarily in the second week of therapy, and was infrequent after Week 4. Rash generally resolved within 1-2 weeks on continued therapy. The incidence of rash was higher in women compared to men in the INTELENCE(R) arm in the Phase trials. Patients with history of NNRTI-related rash did not appear to be at increased risk for the development of INTELENCE(R)-related rash compared to patients without history of NNRTI-related rash.. Common Adverse ReactionsClinical ADRs of moderate intensity or greater (>= Grade 2) and reported in >= 2% of subjects treated with INTELENCE(R) and occurring at higher rate compared to placebo (excess of 1%) are presented in Table 1. Laboratory abnormalities considered ADRs are included in Table 2.Table 1: Treatment-Emergent Adverse ReactionsIncludes adverse reactions at least possibly, probably, or very likely related to the drug. 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).

Patients co-infected with hepatitis and/or hepatitis virusIn Phase trials TMC125-C206 and TMC125-C216, 139 subjects (12.3%) with chronic hepatitis and/or hepatitis virus co-infection out of 1129 subjects were permitted to enroll. AST and ALT abnormalities occurred more frequently in hepatitis and/or hepatitis virus co-infected subjects for both treatment groups. Grade or higher laboratory abnormalities that represent worsening from baseline of AST, ALT or total bilirubin occurred in 27.8%, 25.0% and 7.1% respectively, of INTELENCE(R)-treated co-infected subjects as compared to 6.7%, 7.5% and 1.8% of non-co-infected INTELENCE(R)-treated subjects. In general, adverse events reported by INTELENCE(R)-treated subjects with hepatitis and/or hepatitis virus co-infection were similar to INTELENCE(R)-treated subjects without hepatitis and/or hepatitis virus co-infection.. 6.2Postmarketing Experience. The following events have been identified during postmarketing use of INTELENCE(R). Because these events 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.Fatal cases of toxic epidermal necrolysis have been reported. Severe hypersensitivity reactions including cases of hepatic failure have been reported [see Warnings and Precautions (5.1) ].

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Etravirine is an antiviral drug [see Clinical Pharmacology (12.4) ].. 12.2 Pharmacodynamics. Effects on ElectrocardiogramIn randomized, double-blind, active, and placebo-controlled crossover study, 41 healthy subjects were administered INTELENCE(R) 200 mg b.i.d., INTELENCE(R) 400 mg q.d., placebo, and moxifloxacin 400 mg. After days of dosing, etravirine did not prolong the QT interval. The maximum mean (upper 1-sided 95% CI) baseline and placebo-adjusted QTcF were 0.6 ms (3.3 ms) for 200 mg b.i.d. and -1.0 ms (2.5 ms) for 400 mg q.d. dosing regimens.. 12.3 Pharmacokinetics. Pharmacokinetics in AdultsThe pharmacokinetic properties of INTELENCE(R) were determined in healthy adult subjects and in treatment-experienced HIV-1-infected adult subjects. The systemic exposures (AUC) to etravirine were lower in HIV-1-infected subjects than in healthy subjects.Table 4: Population Pharmacokinetic Estimates of Etravirine 200 mg b.i.d. in HIV-1-Infected Subjects (Integrated Data from Phase Trials at Week 48)All HIV-1-infected subjects enrolled in Phase clinical trials received darunavir/ritonavir 600/100 mg b.i.d. as part of their background regimen. Therefore, the pharmacokinetic parameter estimates shown in Table account for reductions in the pharmacokinetic parameters of etravirine due to co-administration of INTELENCE(R) with darunavir/ritonavir. ParameterEtravirine 200 mg b.i.d.N 575AUC12h (ngh/mL) Geometric Mean +- Standard Deviation4522 +- 4710 Median (Range)4380 (458 59084)C0h (ng/mL) Geometric Mean +- Standard Deviation297 +- 391 Median (Range)298 (2 4852)Note: The median protein binding adjusted EC50 for MT4 cells infected with HIV-1/IIIB in vitro 4 ng/mL.. Absorption and BioavailabilityFollowing oral administration, etravirine was absorbed with Tmax of about 2.5 to hours. The absolute oral bioavailability of INTELENCE(R) is unknown.In healthy subjects, the absorption of etravirine is not affected by co-administration of oral ranitidine or omeprazole, drugs that increase gastric pH.. Effects of Food on Oral AbsorptionThe systemic exposure (AUC) to etravirine was decreased by about 50% when INTELENCE(R) was administered under fasting conditions, as compared to when INTELENCE(R) was administered following meal. Therefore, INTELENCE(R) should always be taken following meal. Within the range of meals studied, the systemic exposures to etravirine were similar. The total caloric content of the various meals evaluated ranged from 345 kilocalories (17 grams fat) to 1160 kilocalories (70 grams fat). [see Dosage and Administration (2) ].. DistributionEtravirine is about 99.9% bound to plasma proteins, primarily to albumin (99.6%) and alpha 1-acid glycoprotein (97.66%-99.02%) in vitro. The distribution of etravirine into compartments other than plasma (e.g., cerebrospinal fluid, genital tract secretions) has not been evaluated in humans.. MetabolismIn vitro experiments with human liver microsomes (HLMs) indicate that etravirine primarily undergoes metabolism by CYP3A, CYP2C9, and CYP2C19 enzymes. The major metabolites, formed by methyl hydroxylation of the dimethylbenzonitrile moiety, were at least 90% less active than etravirine against wild-type HIV in cell culture.. EliminationAfter single dose oral administration of 800 mg 14C-etravirine, 93.7% and 1.2% of the administered dose of 4C-etravirine was recovered in the feces and urine, respectively. Unchanged etravirine accounted for 81.2% to 86.4% of the administered dose in feces. Unchanged etravirine was not detected in urine. The mean (+- standard deviation) terminal elimination half-life of etravirine was about 41 (+- 20) hours.. Special Populations. Hepatic ImpairmentEtravirine is primarily metabolized by the liver. The steady state pharmacokinetic parameters of etravirine were similar after multiple dose administration of INTELENCE(R) to subjects with normal hepatic function (n 16), mild hepatic impairment (Child-Pugh Class A, = 8), and moderate hepatic impairment (Child-Pugh Class B, = 8). The effect of severe hepatic impairment on the pharmacokinetics of etravirine has not been evaluated.. Hepatitis and/or Hepatitis Virus Co-infectionPopulation pharmacokinetic analysis of the TMC125-C206 and TMC125-C216 trials showed reduced clearance for etravirine in HIV-1-infected subjects with hepatitis and/or virus co-infection. Based upon the safety profile of INTELENCE(R) [see Adverse Reactions (6) ], no dose adjustment is necessary in patients co-infected with hepatitis and/or virus.. Renal ImpairmentThe pharmacokinetics of etravirine have not been studied in patients with renal impairment. The results from mass balance study with 14C-etravirine showed that <1.2% of the administered dose of etravirine is excreted in the urine as metabolites. No unchanged drug was detected in the urine. As etravirine is highly bound to plasma proteins, it is unlikely that it will be significantly removed by hemodialysis or peritoneal dialysis.. GenderNo significant pharmacokinetic differences have been observed between men and women. limited number of women were included in clinical studies.. RacePopulation pharmacokinetic analysis of etravirine in HIV-infected subjects did not show an effect of race on exposure to etravirine.. Geriatric PatientsPopulation pharmacokinetic analysis in HIV-infected subjects showed that etravirine pharmacokinetics are not considerably different within the age range (18 to 77 years) evaluated [see Use in Specific Populations (8.5) ].. Pediatric PatientsThe pharmacokinetics of etravirine in pediatric patients have not been evaluated. Dosing recommendations for pediatric patients cannot be made due to insufficient data.. Drug Interactions[See also Drug Interactions (7) .]Etravirine is substrate of CYP3A, CYP2C9, and CYP2C19. Therefore, co-administration of INTELENCE(R) with drugs that induce or inhibit CYP3A, CYP2C9, and CYP2C19 may alter the therapeutic effect or adverse reaction profile of INTELENCE(R).Etravirine is an inducer of CYP3A and inhibitor of CYP2C9, CYP2C19 and P-glycoprotein. Therefore, co-administration of drugs that are substrates of CYP3A, CYP2C9 and CYP2C19 or are transported by P-glycoprotein with INTELENCE(R) may alter the therapeutic effect or adverse reaction profile of the co-administered drug(s).Drug interaction studies were performed with INTELENCE(R) and other drugs likely to be co-administered and some drugs commonly used as probes for pharmacokinetic interactions. The effects of co-administration of other drugs on the AUC, Cmax, and Cmin values of etravirine are summarized in Table (effect of other drugs on INTELENCE(R)). The effect of co-administration of INTELENCE(R) on the AUC, Cmax, and Cmin values of other drugs are summarized in Table (effect of INTELENCE(R) on other drugs).

Mechanism of ActionEtravirine is an NNRTI of human immunodeficiency virus type (HIV-1). Etravirine binds directly to reverse transcriptase (RT) and blocks the RNA-dependent and DNA-dependent DNA polymerase activities by causing disruption of the enzymes catalytic site. Etravirine does not inhibit the human DNA polymerases , and .. Antiviral Activity in Cell CultureEtravirine exhibited activity against laboratory strains and clinical isolates of wild-type HIV-1 in acutely infected T-cell lines, human peripheral blood mononuclear cells, and human monocytes/macrophages with median EC50 values ranging from 0.9 to 5.5 nM (i.e., 0.4 to 2.4 ng/mL). Etravirine demonstrated antiviral activity in cell culture against broad panel of HIV-1 group isolates (subtype A, B, C, D, E, F, G) with EC50 values ranging from 0.29 to 1.65 nM and EC50 values ranging from 11.5 to 21.7 nM against group primary isolates. Etravirine did not show antagonism when studied in combination with the following antiretroviral drugs--the NNRTIs delavirdine, efavirenz, and nevirapine; the N(t)RTIs abacavir, didanosine, emtricitabine, lamivudine, stavudine, tenofovir, zalcitabine, and zidovudine; the PIs amprenavir, atazanavir, darunavir, indinavir, lopinavir, nelfinavir, ritonavir, saquinavir, and tipranavir; the fusion inhibitor enfuvirtide; the integrase strand transfer inhibitor raltegravir and the CCR5 co-receptor antagonist maraviroc.. Resistance. In Cell CultureEtravirine-resistant strains were selected in cell culture originating from wild-type HIV-1 of different origins and subtypes, as well as NNRTI resistant HIV-1. Development of reduced susceptibility to etravirine typically required more than one substitution in reverse transcriptase of which the following were observed most frequently: L100I, E138K, E138G, V179I, Y181C, and M230I.. In Treatment-Experienced SubjectsIn the Phase trials TMC125-C206 and TMC125-C216, substitutions that developed most commonly in subjects with virologic failure at Week 48 to the INTELENCE(R)-containing regimen were V179F, V179I, and Y181C which usually emerged in background of multiple other NNRTI resistance-associated substitutions. In all the trials conducted with INTELENCE(R) in HIV-1 infected subjects, the following substitutions emerged most commonly: L100I, E138G, V179F, V179I, Y181C and H221Y. Other NNRTI-resistance associated substitutions which emerged on etravirine treatment in 10% of the virologic failure isolates included K101E/H/P, K103N/R, V106I/M, V108I, Y181I, Y188L, V189I, G190S/C, N348I and R356K. The emergence of NNRTI substitutions on etravirine treatment contributed to decreased susceptibility to etravirine with median fold-change in etravirine susceptibility of 40-fold from reference and median fold-change of 6-fold from baseline.. Cross-Resistance. Site-Directed NNRTI Mutant VirusEtravirine showed antiviral activity against 55 of 65 HIV-1 strains (85%) with single amino acid substitutions at RT positions associated with NNRTI resistance, including the most commonly found K103N. The single amino acid substitutions associated with an etravirine reduction in susceptibility 3-fold were K101A, K101P, K101Q, E138G, E138Q, Y181C, Y181I, Y181T, Y181V, and M230L, and of these, the greatest reductions were Y181I (13-fold change in EC50 value) and Y181V (17-fold change in EC50 value). Mutant strains containing single NNRTI resistance associated substitution (K101P, K101Q, E138Q, or M230L) had cross-resistance between etravirine and efavirenz. The majority (39 of 61; 64%) of the NNRTI mutant viruses with or amino acid substitutions associated with NNRTI resistance had decreased susceptibility to etravirine (fold-change 3). The highest levels of resistance to etravirine were observed for HIV-1 harboring combination of substitutions V179F Y181C (187 fold-change), V179F Y181I (123 fold-change), or V179F Y181C F227C (888 fold-change).. Clinical IsolatesEtravirine retained fold-change <= against 60% of 6171 NNRTI-resistant clinical isolates. In the same panel, the proportion of clinical isolates resistant to delavirdine, efavirenz and/or nevirapine (defined as fold-change above their respective biological cutoff values in the assay) was 79%, 87%, and 95%, respectively. In TMC125-C206 and TMC125-C216, 34% of the baseline isolates had decreased susceptibility to etravirine (fold-change 3) and 60%, 69%, and 78% of all baseline isolates were resistant to delavirdine, efavirenz, and nevirapine, respectively. Of subjects who received etravirine and were virologic failures in TMC125-C206 and TMC125-C216, 90%, 84%, and 96% of viral isolates obtained at the time of treatment failure were resistant to delavirdine, efavirenz, and nevirapine, respectively. Therefore, cross-resistance to delavirdine, efavirenz, and/or nevirapine is expected after virologic failure with an etravirine-containing regimen for the virologic failure isolates.. Baseline Genotype/Phenotype and Virologic Outcome AnalysesIn TMC125-C206 and TMC125-C216, the presence at baseline of the substitutions L100I, E138A, I167V, V179D, V179F, Y181I, Y181V, or G190S was associated with decreased virologic response to etravirine. Additional substitutions associated with decreased virologic response to etravirine when in the presence of or more additional 2008 IAS-USA defined NNRTI substitutions include A98G, K101H, K103R, V106I, V179T, and Y181C. The presence of K103N, which was the most prevalent NNRTI substitution in TMC125-C206 and TMC125-C216 at baseline, did not affect the response in the INTELENCE(R) arm. Overall, response rates to etravirine decreased as the number of baseline NNRTI substitutions increased (shown as the proportion of subjects achieving viral load 50 plasma HIV RNA copies/mL at Week 48) (Table 7).Table 7: Proportion of Subjects with 50 HIV-1 RNA copies/mL at Week 48 by Baseline Number of IAS-USA-Defined NNRTI Substitutions in the Non-VF Excluded Population of the Pooled TMC125-C206 and TMC125-C216 Trials IAS-USA-Defined NNRTI substitutions2008 IAS-USA defined substitutions V90I, A98G, L100I, K101E/H/P, K103N, V106A/I/M, V108I, E138A, V179D/F/T, Y181C/I/V, Y188C/H/L, G190A/S, P225H, M230L Etravirine ArmsN 561Re-Used/Not Used EnfuvirtideDe Novo EnfuvirtideAll ranges61% (254/418)76% (109/143)068% (52/76)95% (20/21)167% (72/107)77% (24/31)264% (75/118)86% (38/44)355% (36/65)62% (16/26)>= 437% (19/52)52% (11/21)Placebo ArmsN 592All ranges34% (147/435)59% (93/157)Response rates assessed by baseline etravirine phenotype are shown in Table 8.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. 14.1 Treatment-Experienced Subjects. The clinical efficacy of INTELENCE(R) is derived from the analyses of 48-week data from ongoing, randomized, double-blinded, placebo-controlled, Phase trials, TMC125-C206 and TMC125-C216 (DUET-1 and DUET-2). These trials are identical in design and the results below are pooled data from the two trials.TMC125-C206 and TMC125-C216 are Phase studies designed to evaluate the safety and antiretroviral activity of INTELENCE(R) in combination with background regimen (BR) as compared to placebo in combination with BR. Eligible subjects were treatment-experienced HIV-1-infected patients with plasma HIV-1 RNA 5000 copies/mL while on stable antiretroviral regimen for at least weeks. In addition, subjects had or more NNRTI resistance-associated mutations at screening or from prior genotypic analysis, and or more of the following primary PI mutations at screening: D30N, V32I, L33F, M46I/L, I47A/V, G48V, I50L/V, V82A/F/L/S/T, I84V, N88S, or L90M. Randomization was stratified by the intended use of enfuvirtide (ENF) in the BR, previous use of darunavir/ritonavir (DRV/rtv), and screening viral load. Virologic response was defined as undetectable viral load (< 50 HIV-1 RNA copies/mL) at 48 weeks.All study subjects received DRV/rtv as part of their BR, and at least other investigator-selected antiretroviral drugs (N[t]RTIs with or without ENF). Of INTELENCE(R)-treated subjects, 25.5% used ENF for the first time (de novo) and 20.0% re-used ENF. Of placebo-treated subjects, 26.5% used de novo ENF and 20.4% re-used ENF.In the pooled analysis for TMC125-C206 and TMC125-C216, demographics and baseline characteristics were balanced between the INTELENCE(R) arm and the placebo arm. Table 10 displays selected demographic and baseline disease characteristics of the subjects in the INTELENCE(R) and placebo arms.Table 10: Demographic and Baseline Disease Characteristics of Subjects in the TMC125-C206 and TMC125-C216 Trials (Pooled Analysis)Pooled TMC125-C206 and TMC125-C216 TrialsINTELENCE(R) BRN=599Placebo BRN=604RAMs Resistance-Associated Mutations, BR=background regimen FC fold change in EC50 Demographic CharacteristicsMedian Age, years (range) 46 (18-77)45 (18-72)Sex Male90.0%88.6% Female10.0%11.4%Race White70.1%69.8% Black13.2%13.0% Hispanic11.3%12.2% Asian1.3%0.6% Other4.1%4.5%Baseline Disease CharacteristicsMedian Baseline Plasma HIV-1 RNA (range), log10 copies/mL4.8 (2.7-6.8)4.8 (2.2-6.5)Percentage of Subjects with Baseline Viral Load: 30,000 copies/mL27.5%28.8% >= 30,000 copies/mL and 100,000 copies/mL34.4%35.3% >= 100,000 copies/mL38.1%35.9%Median Baseline CD4+ Cell Count (range), cells/mm3 99 (1-789)109 (0-912)Percentage of Subjects with Baseline CD4+ Cell Count: 50 cells/mm3 35.6%34.7% >= 50 cells/mm3 and 200 cells/mm3 34.8%34.5% >= 200 cells/mm3 29.6%30.8%Median (range) Number of Primary PI MutationsIAS-USA primary PI mutations [August/September 2007]: D30N, V32I, L33F, M46I/L, I47A/V, G48V, I50L/V, I54L/M, L76V, V82A/F/L/S/T, I84V, N88S, L90M (0-7)4 (0-8)Percentage of Subjects with Previous Use of NNRTIs: 08.2%7.9% 146.9%46.7% >144.9%45.4%Percentage of Subjects with Previous Use of the following NNRTIs: Efavirenz70.3%72.5% Nevirapine57.1%58.6% Delavirdine13.7%12.6%Median (range) Number of NNRTI RAMsTibotec NNRTI RAMs [June 2008]: A98G, V90I, L100I, K101E/H/P/Q, K103H/N/S/T, V106A/M/I, V108I, E138A/G/K/Q, V179D/E/F/G/I/T, Y181C/I/V, Y188C/H/L, V189I, G190A/C/E/Q/S, H221Y, P255H, F227C/L, M230I/L, P236L, K238N/T, Y318F (0-8)2 (0-7)Median Fold Change of the Virus for the Following NNRTIs: Delavirdine27.326.1 Efavirenz63.945.4 Etravirine1.61.5 Nevirapine74.374.0Percentage of Subjects with Previous Use of Fusion Inhibitor39.6%42.2%Percentage of Subjects with Phenotypic Sensitivity Score (PSS) for the background therapy The PSS was calculated for the background therapy (as determined on Day 7).

Of the study population using ENF de novo, 67.3% of INTELENCE(R)-treated subjects and 57.2% of placebo-treated subjects achieved HIV-1 RNA 50 copies/mL.Treatment-emergent CDC category events occurred in 4% of INTELENCE(R)-treated subjects and 8.4% of placebo-treated subjects.Study TMC125-C227 was randomized, exploratory, active-controlled, open-label, Phase 2b trial. Eligible subjects were treatment-experienced, PI-naive HIV-1-infected patients with genotypic evidence of NNRTI resistance at screening or from prior genotypic analysis. The virologic response was evaluated in 116 subjects who were randomized to INTELENCE(R) (n=59) or an investigator-selected PI (n=57), each given with investigator-selected N(t)RTIs. INTELENCE(R)-treated subjects had lower antiviral responses associated with reduced susceptibility to the N(t)RTIs and to INTELENCE(R) as compared to the control PI-treated subjects.

DRUG INTERACTIONS SECTION.

7 DRUG INTERACTIONS. Etravirine is substrate of CYP3A, CYP2C9, and CYP2C19. Therefore, co-administration of INTELENCE(R) with drugs that induce or inhibit CYP3A, CYP2C9, and CYP2C19 may alter the therapeutic effect or adverse reaction profile of INTELENCE(R) (see Table 3). [See also Clinical Pharmacology (12.3) .]Etravirine is an inducer of CYP3A and inhibitor of CYP2C9, CYP2C19 and P-glycoprotein. Therefore, co-administration of drugs that are substrates of CYP3A, CYP2C9 and CYP2C19 or are transported by P-glycoprotein with INTELENCE(R) may alter the therapeutic effect or adverse reaction profile of the co-administered drug(s) (see Table 3). [See also Clinical Pharmacology (12.3) .]Table shows the established and other potentially significant drug interactions based on which, alterations in dose or regimen of INTELENCE(R) and/or co-administered drug may be recommended. Drugs that are not recommended for co-administration with INTELENCE(R) are also included in Table 3. Table 3: 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 Etravirine or Concomitant DrugClinical Comment increase, decrease, <-> no changeHIV-Antiviral Agents: Non-Nucleoside Reverse Transcriptase Inhibitors (NNRTIs)efavirenzThe interaction between INTELENCE(R) and the drug was evaluated in clinical study. All other drug interactions shown are predicted. nevirapine etravirineCombining two NNRTIs has not been shown to be beneficial. Concomitant use of INTELENCE(R) with efavirenz or nevirapine may cause significant decrease in the plasma concentrations of etravirine and loss of therapeutic effect of INTELENCE(R). INTELENCE(R) and other NNRTIs should not be co-administered.delavirdine etravirineCombining two NNRTIs has not been shown to be beneficial. INTELENCE(R) and delavirdine should not be co-administered.HIV-Antiviral Agents: Protease Inhibitors (PIs)atazanavir (without ritonavir) atazanavirConcomitant use of INTELENCE(R) with atazanavir without low-dose ritonavir may cause significant alteration in the plasma concentration of atazanavir. INTELENCE(R) should not be co-administered with atazanavir without low-dose ritonavir.atazanavir/ritonavir atazanavir etravirineConcomitant use of INTELENCE(R) with atazanavir/ritonavir may cause significant decrease in atazanavir Cmin and loss of therapeutic effect of atazanavir. In addition, the mean systemic exposure (AUC) of etravirine after co-administration of INTELENCE(R) with atazanavir/ritonavir is anticipated to be higher than the mean systemic exposure of etravirine observed in the Phase trials after co-administration of INTELENCE(R) and darunavir/ritonavir (as part of the background regimen). INTELENCE(R) and atazanavir/ritonavir should not be co-administered.darunavir/ritonavir etravirineThe mean systemic exposure (AUC) of etravirine was reduced when INTELENCE(R) was co-administered with darunavir/ritonavir. Because all subjects in the Phase trials received darunavir/ritonavir as part of the background regimen and etravirine exposures from these trials were determined to be safe and effective, INTELENCE(R) and darunavir/ritonavir can be co-administered without dose adjustments.fosamprenavir(without ritonavir) amprenavirConcomitant use of INTELENCE(R) with fosamprenavir without low-dose ritonavir may cause significant alteration in the plasma concentration of amprenavir. INTELENCE(R) should not be co-administered with fosamprenavir without low-dose ritonavir.fosamprenavir/ritonavir amprenavirDue to significant increase in the systemic exposure of amprenavir, the appropriate doses of the combination of INTELENCE(R) and fosamprenavir/ritonavir have not been established. INTELENCE(R) and fosamprenavir/ritonavir should not be co-administered.indinavir (without ritonavir) indinavirConcomitant use of INTELENCE(R) with indinavir without low-dose ritonavir may cause significant alteration in the plasma concentration of indinavir. INTELENCE(R) should not be co-administered with indinavir without low-dose ritonavir.lopinavir/ritonavir etravirineThe mean systemic exposure (AUC) of etravirine was reduced after co-administration of INTELENCE(R) with lopinavir/ritonavir (tablet). Because the reduction in the mean systemic exposures of etravirine in the presence of lopinavir/ritonavir is similar to the reduction in mean systemic exposures of etravirine in the presence of darunavir/ritonavir, INTELENCE(R) and lopinavir/ritonavir can be co-administered without dose adjustments.nelfinavir(without ritonavir) nelfinavirConcomitant use of INTELENCE(R) with nelfinavir without low-dose ritonavir may cause significant alteration in the plasma concentration of nelfinavir. INTELENCE(R) should not be co-administered with nelfinavir without low-dose ritonavir.ritonavir etravirineConcomitant use of INTELENCE(R) with ritonavir 600 mg b.i.d. may cause significant decrease in the plasma concentration of etravirine and loss of therapeutic effect of INTELENCE(R). INTELENCE(R) and ritonavir 600 mg b.i.d. should not be co-administered.saquinavir/ritonavir etravirineThe mean systemic exposure (AUC) of etravirine was reduced when INTELENCE(R) was co-administered with saquinavir/ritonavir. Because the reduction in the mean systemic exposures of etravirine in the presence of saquinavir/ritonavir is similar to the reduction in mean systemic exposures of etravirine in the presence of darunavir/ritonavir, INTELENCE(R) and saquinavir/ritonavir can be co-administered without dose adjustments.tipranavir/ritonavir etravirineConcomitant use of INTELENCE(R) with tipranavir/ritonavir may cause significant decrease in the plasma concentrations of etravirine and loss of therapeutic effect of INTELENCE(R). INTELENCE(R) and tipranavir/ritonavir should not be co-administered.CCR5 Antagonistsmaraviroc <-> etravirine maraviroc When INTELENCE(R) is co-administered with maraviroc in the absence of potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor), the recommended dose of maraviroc is 600 mg b.i.d. No dose adjustment of INTELENCE(R) is needed.maraviroc/darunavir/ritonavir The reference for etravirine exposure is the pharmacokinetic parameters of etravirine in the presence of darunavir/ritonavir <-> etravirine maravirocWhen INTELENCE(R) is co-administered with maraviroc in the presence of potent CYP3A inhibitor (e.g., ritonavir boosted protease inhibitor), the recommended dose of maraviroc is 150 mg b.i.d. No dose adjustment of INTELENCE(R) is needed.Other AgentsAntiarrhythmics:digoxin<-> etravirine digoxinFor patients who are initiating combination of INTELENCE(R) and digoxin, the lowest dose of digoxin should initially be prescribed. For patients on stable digoxin regimen and initiating INTELENCE(R), no dose adjustment of either INTELENCE(R) or digoxin is needed. The serum digoxin concentrations should be monitored and used for titration of the digoxin dose to obtain the desired clinical effect.amiodarone, bepridil, disopyramide, flecainide, lidocaine (systemic), mexiletine, propafenone, quinidine antiarrhythmicsConcentrations of these antiarrhythmics may be decreased when co-administered with INTELENCE(R). INTELENCE(R) and antiarrhythmics should be co-administered with caution. Drug concentration monitoring is recommended, if available.Anticoagulants: warfarin anticoagulantsWarfarin concentrations may be increased when co-administered with INTELENCE(R). The international normalized ratio (INR) should be monitored when warfarin is combined with INTELENCE(R).Anticonvulsants: carbamazepine, phenobarbital, phenytoin etravirineCarbamazepine, phenobarbital and phenytoin are inducers of CYP450 enzymes. INTELENCE(R) should not be used in combination with carbamazepine, phenobarbital, or phenytoin as co-administration may cause significant decreases in etravirine plasma concentrations and loss of therapeutic effect of INTELENCE(R).Antifungals: fluconazole, voriconazole etravirine <-> fluconazole voriconazoleCo-administration of etravirine and fluconazole significantly increased etravirine exposures. The amount of safety data at these increased etravirine exposures is limited, therefore, etravirine and fluconazole should be co-administered with caution. No dose adjustment of INTELENCE(R) or fluconazole is needed.Co-administration of etravirine and voriconazole significantly increased etravirine exposures. The amount of safety data at these increased etravirine exposures is limited, therefore, etravirine and voriconazole should be co-administered with caution. No dose adjustment of INTELENCE(R) or voriconazole is needed.Antifungals:itraconazole,ketoconazole,posaconazole etravirine itraconazole ketoconazole<-> posaconazolePosaconazole, potent inhibitor of CYP3A4, may increase plasma concentrations of etravirine. Itraconazole and ketoconazole are potent inhibitors as well as substrates of CYP3A4. Concomitant systemic use of itraconazole or ketoconazole and INTELENCE(R) may increase plasma concentrations of etravirine. Simultaneously, plasma concentrations of itraconazole or ketoconazole may be decreased by INTELENCE(R). Dose adjustments for itraconazole, ketoconazole or posaconazole may be necessary depending on the other co-administered drugs.Antiinfectives: clarithromycin etravirine clarithromycin 14-OH-clarithromycinClarithromycin exposure was decreased by INTELENCE(R); however, concentrations of the active metabolite, 14-hydroxy-clarithromycin, were increased. Because 14-hydroxy-clarithromycin has reduced activity against Mycobacterium avium complex (MAC), overall activity against this pathogen may be altered. Alternatives to clarithromycin, such as azithromycin, should be considered for the treatment of MAC.Antimycobacterials: rifampin, rifapentine etravirineRifampin and rifapentine are potent inducers of CYP450 enzymes. INTELENCE(R) should not be used with rifampin or rifapentine as co-administration may cause significant decreases in etravirine plasma concentrations and loss of therapeutic effect of INTELENCE(R).Antimycobacterials: rifabutin etravirine rifabutin 25-O-desacetylrifabutinIf INTELENCE(R) is NOT co-administered with protease inhibitor/ritonavir, then rifabutin at dose of 300 mg q.d. is recommended.If INTELENCE(R) is co-administered with darunavir/ritonavir, lopinavir/ritonavir or saquinavir/ritonavir, then rifabutin should not be co-administered due to the potential for significant reductions in etravirine exposure.Benzodiazepines: diazepam diazepamConcomitant use of INTELENCE(R) with diazepam may increase plasma concentrations of diazepam. decrease in diazepam dose may be needed.Corticosteroids: dexamethasone (systemic) etravirineSystemic dexamethasone induces CYP3A and can decrease etravirine plasma concentrations. This may result in loss of therapeutic effect of INTELENCE(R). Systemic dexamethasone should be used with caution or alternatives should be considered, particularly for long-term use.Herbal Products: St. Johns wort (Hypericum perforatum) etravirineConcomitant use of INTELENCE(R) with products containing St. Johns wort may cause significant decreases in etravirine plasma concentrations and loss of therapeutic effect of INTELENCE(R). INTELENCE(R) and products containing St. Johns wort should not be co-administered.HMG-CoAReductase Inhibitors: atorvastatin fluvastatin, lovastatin, pravastatin, rosuvastatin, simvastatin<-> etravirine atorvastatin 2-OH-atorvastatin <-> etravirine fluvastatin, lovastatin, <-> pravastatin, <-> rosuvastatin, simvastatinThe combination of INTELENCE(R) and atorvastatin can be given without dose adjustments, however, the dose of atorvastatin may need to be altered based on clinical response. No interaction between pravastatin, rosuvastatin and INTELENCE(R) is expected. Lovastatin and simvastatin are CYP3A substrates and co-administration with INTELENCE(R) may result in lower plasma concentrations of the HMG-CoA reductase inhibitor.
