Edurant Ped Drug Information

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a 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 Adults The safety assessment is based on the Week 96 pooled data from 1368 patients in the Phase 3 controlled trials TMC278-C209 (ECHO) and TMC278-C215 (THRIVE) in antiretroviral treatment-naïve HIV-1 infected adult patients, 686 of whom received EDURANT (25 mg once daily) . The median duration of exposure for patients in the EDURANT arm and efavirenz arm was 104.3 and 104.1 weeks, respectively. Most adverse reactions occurred in the first 48 weeks of treatment.

The proportion of subjects who discontinued treatment with EDURANT or efavirenz due to adverse reaction, regardless of severity, was 2% and 4%, respectively. The most common adverse reactions 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 1 (<1%) subject in the EDURANT arm and 10 (2%) subjects in the efavirenz arm.

Common Adverse Reactions Adverse reactions of at least moderate intensity (≥Grade 2) reported in at least 2% of adult subjects are presented in Table 3. Selected laboratory abnormalities are included in Table 4. Table 3: Selected Adverse Reactions of at Least Moderate Intensity Intensities 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 3 trials through 96 weeks. Less Common Adverse Reactions Adverse reactions of at least moderate intensity (≥Grade 2) occurring in less than 2% of antiretroviral treatment-naïve subjects receiving EDURANT are listed below by System Organ Class.

Some adverse events have been included because of investigator's assessment of potential causal relationship and were considered serious or have been reported in more than 1 subject treated with EDURANT. Gastrointestinal Disorders : diarrhea, abdominal discomfort Hepatobiliary Disorders : cholecystitis, cholelithiasis Metabolism and Nutrition Disorders : decreased appetite Nervous System Disorders : somnolence Psychiatric Disorders : sleep disorders, anxiety Renal and Urinary Disorders : glomerulonephritis membranous, glomerulonephritis mesangioproliferative, nephrolithiasis Laboratory Abnormalities in Treatment-Naïve Subjects The percentage of subjects treated with EDURANT or efavirenz in the Phase 3 trials with selected laboratory abnormalities (Grades 1 to 4), representing worst Grade toxicity are shown in Table 4.

In the EDURANT group, 43/588 (7%) of subjects with a 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%) 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 Creatinine In the pooled Phase 3 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 a 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 Lipids Changes from baseline in total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides are presented in Table 5. The clinical benefit of these findings has not been demonstrated.

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 Cabotegravir Safety findings from Phase 3/3b 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 extended-release injectable suspension; rilpivirine extended-release injectable suspension) for additional information. Clinical Trials Experience in Pediatric Patients Pediatric Population (≥12 to less than 18 years of age) Trial TMC278-C213 Cohort 1 The safety assessment is based on the Week 48 analysis of the single-arm, open-label, Phase 2 trial, TMC278-C213 Cohort 1, in which 36 antiretroviral treatment-naïve 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 . The median duration of exposure was 63.5 weeks.

There were no patients who discontinued treatment due to adverse reactions. No new adverse reactions were identified compared to those seen in adults. Adverse reactions were reported in nineteen pediatric subjects (53%). Most adverse reactions were Grade 1 or 2. The most common adverse reactions reported in at least 2 subjects (regardless of severity) include headache (19%), depression (19%), somnolence (14%), nausea (11%), dizziness (8%), abdominal pain (8%), vomiting (6%) and rash (6%). Observed laboratory abnormalities were comparable to those in adults.

Adrenal Function In trial TMC278-C213 Cohort 1, at Week 48, the overall mean change from baseline in basal cortisol showed an increase of 1.59 micrograms/dL. Six of 30 (20%) subjects with a 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.

Trial 208580 Based on data from the Week 16 analysis of the MOCHA trial in 15 adolescents (12 to less than 18 years of age and weighing ≥35 kg) receiving EDURANT (25 mg once daily) in addition to continuing background antiretroviral therapy, the safety profile during the oral lead-in period in adolescents was consistent with the safety profile established with EDURANT in adults. Pediatric Population (≥2 to less than 12 years of age) Two clinical trials were conducted in pediatric subjects weighing at least 16 kg (5 to less than 12 years of age). A total of 18 and 26 pediatric subjects were enrolled in Trial TMC278-C213 and Trial TMC278HTX2002, respectively. Overall, the safety data in these pediatric studies were similar to those observed in adults.

Safety results from the two trials are summarized below. Trial TMC278-C213 Cohort 2 Cohort 2 of the single-arm, open-label Phase 2 trial, TMC278-C213 evaluated the safety of the EDURANT and EDURANT PED weight adjusted doses 25, 15 and 12.5 mg once daily in antiretroviral treatment-naïve HIV-1 infected patients (≥6 to <12 years of age and weighing at least 17 kg) . The median duration of exposure for patients in the Week 48 analysis (including post-Week 48 extension) was 69.5 (range 35 to 218) weeks. All adverse reactions were Grade 1 or 2. Adverse reactions reported in at least 2 subjects, regardless of grading, in Trial TMC278-C213 Cohort 2 were: decreased appetite (3/18, 17%), vomiting (2/18, 11%), ALT increased (2/18, 11%), AST increased (2/18, 11%), and rash (2/18, 11%). No adverse reactions led to discontinuation.

Adrenal Function In trial TMC278-C213 Cohort 2, basal cortisol at baseline was normal (≥9 μg/dL) for 4/18 subjects, low for 13/18 subjects, and missing for 1/18 subjects. Among the 4 subjects with normal basal cortisol at baseline, 3 subjects had either normal basal cortisol levels (≥9 μg/dL) or normal cortisol levels 1 hour after ACTH stimulation (≥18.1 μg/dL) throughout the trial and/or at the last available visit (Week 24 and Week 72), and 1 subject had low basal cortisol at the last available assessment (Week 48) and no ACTH stimulation test was performed. Among the 13 subjects with low basal cortisol pre-dose at baseline, 2 subjects had low basal and ACTH stimulated cortisol values throughout the trial, including ACTH stimulated cortisol at baseline before starting treatment with rilpivirine.

For both subjects, no adverse events suggestive for adrenal insufficiency were reported. The remaining 11 subjects had normal serum cortisol values after ACTH stimulation at baseline and/or during treatment. Trial TMC278HTX2002 The single arm, open-label Phase 2 trial, TMC278HTX2002, evaluated the safety of EDURANT and EDURANT PED weight-adjusted doses 25, 15 and 12.5 mg once daily in virologically suppressed HIV-1 infected patients (≥2 to <12 years of age and weighing at least 16 kg). The median duration of exposure for patients in the Week 48 analysis was 48.4 (range 47 to 52) weeks.

All adverse reactions were Grade 1 or 2. Adverse reactions reported in at least 2 subjects, regardless of grading, in Trial TMC278HTX2002 were: vomiting (4/26, 15%), abdominal pain (3/26, 12%), nausea (2/26, 8%), ALT increased (3/26, 12%), AST increased (2/26, 8%), and decreased appetite (2/26, 8%). No adverse reactions led to discontinuation. Adrenal Function In trial TMC278HTX2002, 15/26 subjects had either normal basal cortisol (≥9 μg/dL) or normal cortisol 1 hour after ACTH stimulation (≥18.1 μg/dL), 9 had low basal cortisol on Day 1, and in 2 subjects the baseline value was missing. From the 19 subjects with low basal cortisol at Week 48, in 15 subjects, the Week 48 serum cortisol levels returned to normal (≥248 nmol/L) after repeat serum basal cortisol testing or was normal after ACTH stimulation testing (≥500 nmol/L). In 4 subjects, the serum cortisol levels remained low after repeat serum basal cortisol testing or after ACTH stimulation testing.

At Week 48, 6 subjects had normal (basal) cortisol (≥9 ug/dL) and the Week 48 result was not available for 1 subject.

Postmarketing Experience Adverse reactions have been identified during postmarketing experience in patients

receiving a rilpivirine containing regimen. Because these reactions are reported voluntarily from a population of unknown size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Renal and Genitourinary Disorders: nephrotic syndrome Skin and Subcutaneous Tissue Disorders: Severe skin and hypersensitivity reactions including DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms)

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 or EDURANT PED 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 or EDURANT PED and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine.

Coadministration of EDURANT or EDURANT PED 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 or EDURANT PED at the recommended doses are not likely to have a clinically relevant effect on the exposure of drugs metabolized by CYP enzymes. Table 6 shows the established and other potentially significant drug interactions based on which alterations in dose or regimen of EDURANT or EDURANT PED and/or coadministered drug may be recommended.

Drugs that are not recommended for coadministration with EDURANT or EDURANT PED are also included in Table 6. Table 6: Established and Other Potentially Significant Drug Interactions: Alterations in Dose or Regimen May Be Recommended Based on Drug Interaction Studies or Predicted Interaction Concomitant Drug Class: Drug Name Effect 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 2 hours before or at least 4 hours after rilpivirine) The combination of EDURANT or EDURANT PED and antacids should be used with caution as coadministration may cause significant decreases in rilpivirine plasma concentrations (increase in gastric pH). Antacids should only be administered either at least 2 hours before or at least 4 hours after EDURANT or EDURANT PED. ↓ rilpivirine (concomitant intake) Anticonvulsants: carbamazepine oxcarbazepine phenobarbital phenytoin ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED . Antimycobacterials: rifampin rifapentine ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED . Antimycobacterials: rifabutin The interaction between EDURANT and the drug was evaluated in a clinical study. All other drug-drug interactions shown are predicted. ↓ rilpivirine Concomitant use of EDURANT with rifabutin may cause a decrease in the plasma concentrations of rilpivirine (induction of CYP3A enzymes). Throughout coadministration of EDURANT with rifabutin, the EDURANT dose should be increased from 25 mg once daily to 50 mg once daily. When rifabutin coadministration is stopped, the EDURANT dose should be decreased to 25 mg once daily.

Azole Antifungal Agents: fluconazole itraconazole ketoconazole This interaction study has been performed with a dose higher than the recommended dose for EDURANT assessing the maximal effect on the coadministered drug. The dosing recommendation is applicable to the recommended doses of EDURANT once daily. posaconazole voriconazole ↑ rilpivirine ↓ ketoconazole Concomitant use of EDURANT or EDURANT PED with azole antifungal agents may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No rilpivirine dose adjustment is required when EDURANT or EDURANT PED is coadministered with azole antifungal agents. Clinically monitor for breakthrough fungal infections when azole antifungals are coadministered with EDURANT or EDURANT PED. Glucocorticoid (systemic): dexamethasone (more than a single-dose treatment) ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED . H 2 -Receptor Antagonists: cimetidine famotidine nizatidine ranitidine ↔ rilpivirine (famotidine taken 12 hours before rilpivirine or 4 hours after rilpivirine) The combination of EDURANT or EDURANT PED and H 2 -receptor antagonists should be used with caution as coadministration may cause significant decreases in rilpivirine plasma concentrations (increase in gastric pH). H 2 -receptor antagonists should only be administered at least 12 hours before or at least 4 hours after EDURANT or EDURANT PED. ↓ rilpivirine (famotidine taken 2 hours before rilpivirine) Herbal Products: St.

John's wort ( Hypericum perforatum ) ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED . HIV-Antiviral Agents: Non-nucleoside Reverse Transcriptase Inhibitors (NNRTIs) NNRTI (delavirdine) ↑ rilpivirine ↔ delavirdine It is not recommended to coadminister EDURANT or EDURANT PED with delavirdine and other NNRTIs. Other NNRTIs (efavirenz, etravirine, nevirapine) ↓ rilpivirine ↔ other NNRTIs HIV-Antiviral Agents: Nucleoside Reverse Transcriptase Inhibitors (NRTIs) didanosine ↔ rilpivirine ↔ didanosine No dose adjustment is required when EDURANT or EDURANT PED is coadministered with didanosine. Didanosine is to be administered on an empty stomach and at least two hours before or at least four hours after EDURANT or EDURANT PED (which should be administered with a meal). HIV-Antiviral Agents: Protease Inhibitors (PIs)-Boosted (i.e., with coadministration of low-dose ritonavir) or Unboosted (i.e., without coadministration of low-dose ritonavir) darunavir/ritonavir ↑ rilpivirine ↔ boosted darunavir Concomitant use of EDURANT or EDURANT PED with darunavir/ritonavir may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No dose adjustment is required when EDURANT or EDURANT PED is coadministered with darunavir/ritonavir.

Lopinavir/ritonavir ↑ rilpivirine ↔ boosted lopinavir Concomitant use of EDURANT or EDURANT PED with lopinavir/ritonavir may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). No dose adjustment is required when EDURANT or EDURANT PED is coadministered with lopinavir/ritonavir. Other boosted PIs (atazanavir/ritonavir, fosamprenavir/ritonavir, saquinavir/ritonavir, tipranavir/ritonavir) ↑ rilpivirine ↔ boosted PI Concomitant use of EDURANT or EDURANT PED with boosted PIs may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). EDURANT or EDURANT PED is not expected to affect the plasma concentrations of coadministered PIs. Unboosted PIs (atazanavir, fosamprenavir, indinavir, nelfinavir) ↑ rilpivirine ↔ unboosted PI Concomitant use of EDURANT or EDURANT PED with unboosted PIs may cause an increase in the plasma concentrations of rilpivirine (inhibition of CYP3A enzymes). EDURANT or EDURANT PED is not expected to affect the plasma concentrations of coadministered PIs.

Macrolide or ketolide antibiotics: azithromycin clarithromycin erythromycin ↑ rilpivirine ↔ azithromycin ↔ clarithromycin ↔ erythromycin Macrolides are expected to increase concentrations of rilpivirine and are associated with a risk of Torsade de Pointes. Where possible, consider alternatives, such as azithromycin, which increases rilpivirine concentrations less than other macrolides. Narcotic Analgesics: methadone ↓ R(-) methadone ↓ S(+) methadone No dose adjustments are required when initiating coadministration of methadone with EDURANT or EDURANT PED. However, clinical monitoring is recommended as methadone maintenance therapy may need to be adjusted in some patients.

Proton Pump Inhibitors: e.g., esomeprazole lansoprazole omeprazole pantoprazole rabeprazole ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED . In addition to the drugs included in Table 6, the interaction between EDURANT and the following drugs was evaluated in clinical studies and no dose adjustment is needed for either drug : acetaminophen, atorvastatin, chlorzoxazone, cabotegravir, ethinylestradiol, norethindrone, raltegravir, sildenafil, simeprevir and tenofovir disoproxil fumarate. Rilpivirine did not have a clinically significant effect on the pharmacokinetics of digoxin or metformin. No clinically relevant drug-drug interaction is expected when EDURANT or EDURANT PED is coadministered with maraviroc, ribavirin or the NRTIs abacavir, emtricitabine, lamivudine, stavudine and zidovudine.

Consider alternatives to EDURANT or EDURANT PED when coadministered with drugs with a known risk of torsade de pointes. EDURANT and EDURANT PED should not be used in combination with NNRTIs. Coadministration of EDURANT or EDURANT PED with drugs that induce or inhibit CYP3A may affect the plasma concentrations of rilpivirine.

Coadministration of EDURANT or EDURANT PED with drugs that increase gastric pH may decrease plasma concentrations of rilpivirine. Refer to the Full Prescribing Information for other drugs that should not be coadministered with EDURANT or EDURANT PED and for other drugs that may require a change in dose or regimen. QT Prolonging Drugs There is limited information available on the potential for a pharmacodynamic interaction between rilpivirine and drugs that prolong the QTc interval of the electrocardiogram.

In a 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 . Consider alternatives to EDURANT when coadministered with a drug with a known risk of torsade de pointes.

Pregnancy Pregnancy Exposure Registry There is a 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 Summary Available 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 a limited geographic area, and does not include outcomes for births that occurred at <20 weeks gestation. In a 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 (≥12 years of age and weighing at least 32 kg) at the recommended dose of 25 mg once daily (see Data ). Clinical Considerations Dosing During Pregnancy and the Postpartum Period Based on the experience of HIV-1-infected pregnant women who completed a clinical trial through the postpartum period with a rilpivirine-based regimen, no dose adjustments are required for pregnant patients who are already on a stable EDURANT regimen prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL). Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely . Data Human Data Based on prospective reports to the APR of over 550 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 1.4% (95% CI: 0.6% to 2.8%) and 1.5% (95% CI: 0.3% to 4.3%) following first and second/third trimester exposure, respectively, to rilpivirine-containing regimens. Rilpivirine in combination with a background regimen was evaluated in a clinical trial of 19 HIV-1 infected pregnant women during the second and third trimesters and postpartum.

Each of the women were on a 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 (C 0h 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 9 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 Data Rilpivirine 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 6 through 17, and 6 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 (≥12 years of age and weighing >32 kg) at the recommended dose of 25 mg once daily. In a 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 (≥12 years of age and weighing >32 kg) at the recommended dose of 25 mg daily.

Pediatric Use The safety and effectiveness of EDURANT and EDURANT PED has been established for the treatment of HIV-1 infection in treatment-naïve pediatric patients 2 years of age and older and weighing at least 14 kg. Use of EDURANT or EDURANT PED in this population is supported by three trials: TMC278-C213, TMC278HTX2002 and MOCHA. Trial TMC278-C213 TMC278-C213 was a single arm, open-label, Phase 2 trial in antiretroviral treatment-naïve HIV-1 infected pediatric subjects, and was divided into two Cohorts. Cohort 1 evaluated the safety, efficacy and pharmacokinetics of EDURANT and enrolled 36 children aged 12 to less than 18 years of age and weighing at least 32 kg . Cohort 2 evaluated the safety, tolerability, antiviral activity and pharmacokinetics of EDURANT and EDURANT PED weight-adjusted doses 25, 15 and 12.5 mg daily, and enrolled 18 children aged 6 to less than 12 years of age and weighing at least 17 kg . Trial TMC278HTX2002 The safety, tolerability, antiviral activity and pharmacokinetics of EDURANT and EDURANT PED weight-adjusted doses 25, 15 and 12.5 mg daily was evaluated in a single-arm, open-label Phase 2 trial in 26 HIV-1 infected pediatric subjects 2 to less than 12 years of age and weighing at least 16 kg.

Trial TMC278HTX2002 supports the safety and effectiveness of EDURANT and EDURANT PED in treatment-naïve HIV-1 infected pediatric patients 2 to less than 6 years of age. MOCHA Trial (NCT03497676) The safety, tolerability, and pharmacokinetics of oral and injectable cabotegravir and oral and injectable rilpivirine are being assessed in an ongoing Phase 1/2 multicenter, open-label, non- comparative study, MOCHA (IMPAACT 2017) . Refer to the VOCABRIA and CABENUVA prescribing information for additional information when EDURANT is used in combination with cabotegravir. The safety and effectivness of EDURANT in these pediatric subjects were similar to that seen in adults, and there were no significant changes on rilpivirine exposures.

Safety and effectiveness in pediatric patients less than 2 years of age or weighing less than 14 kg have not been established. Treatment with EDURANT PED is not recommended in pediatric patients less than 2 years of age or weighing below 14 kg .

and EDURANT PED are contraindicated for coadministration with the drugs in Table 2 for which significant decreases in rilpivirine plasma concentrations may occur due to CYP3A enzyme induction or gastric pH increase, which may result in loss of virologic response and possible resistance to EDURANT or EDURANT PED or to the class of NNRTIs . Table 2: Drugs That are Contraindicated with EDURANT and EDURANT PED Drug Class Contraindicated Drugs in Class Clinical Comment Anticonvulsants Carbamazepine Oxcarbazepine Phenobarbital Phenytoin Potential for significant decreases in rilpivirine plasma concentrations due to CYP3A enzyme induction, which may result in loss of virologic response. Antimycobacterials Rifampin Rifapentine Glucocorticoid (systemic) Dexamethasone (more than a single-dose treatment) Herbal Products St. John's wort ( Hypericum perforatum ) Proton Pump Inhibitors e.g., Esomeprazole Lansoprazole Omeprazole Pantoprazole Rabeprazole Potential for significant decreases in rilpivirine plasma concentrations due to gastric pH increase, which may result in loss of virologic response.

Coadministration of EDURANT or EDURANT PED is contraindicated with drugs where significant decreases in rilpivirine plasma concentrations may occur, which may result in loss of virologic response and possible resistance and cross-resistance.

There is no specific antidote for overdose with EDURANT or EDURANT PED. Human experience of overdose with EDURANT or EDURANT PED is limited. Treatment of overdose with EDURANT or EDURANT PED consists of general supportive measures including monitoring of vital signs and ECG (QT interval) as well as observation of the clinical status of the patient. It is advisable to contact a poison control center to obtain the latest recommendations for the management of an overdose.

Since rilpivirine is highly bound to plasma protein, dialysis is unlikely to result in significant removal of the active substance.
