Rilpivirine

12.1 Mechanism of Action Rilpivirine is an antiviral drug [see Microbiology (12.4) ] .

1 INDICATIONS AND USAGE EDURANT and EDURANT PED are a human immunodeficiency virus type 1 (HIV-1) specific, non-nucleoside reverse transcriptase inhibitor (NNRTI) indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in treatment-naïve patients 2 years of age and older and weighing at least 14 kg with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1.1 ). Limitations of Use: More EDURANT treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA ≥50 copies/mL) compared to EDURANT treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1.1 , 14 ) EDURANT is indicated in combination with VOCABRIA (cabotegravir), for short-term treatment of HIV-1 infection in adults and adolescents 12 years and older and weighing at least 35 kg who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine. ( 1.2 ) 1.1 Treatment of HIV-1 in Treatment-Naïve Patients EDURANT and EDURANT PED, in combination with other antiretroviral agents, is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in antiretroviral treatment-naïve patients 2 years of age and older and weighing at least 14 kg with plasma HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy. Limitations of Use More EDURANT treated subjects with HIV-1 RNA greater than 100,000 copies/mL at the start of therapy experienced virologic failure (HIV-1 RNA ≥50 copies/mL) compared to EDURANT treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL [see Clinical Studies (14.1) ] . 1.2 Treatment of HIV-1 in Combination with Cabotegravir EDURANT is indicated in combination with VOCABRIA (cabotegravir) for short-term treatment of HIV-1 infection in adults and adolescents 12 years and older and weighin

2 DOSAGE AND ADMINISTRATION One 25 mg EDURANT tablet taken once daily with a meal for patients weighing at least 25 kg. ( 2.2 ) Pediatric patients 2 years of age and older and weighing at least 14 kg to less than 25 kg: Dosage of EDURANT PED is based on body weight. ( 2.3 ) EDURANT PED must be dispersed in drinking water and taken with a meal. ( 2.4 ) Do not substitute EDURANT tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. ( 2.1 , 5.6 ) See full prescribing information for dosing information when used in combination with cabotegravir. ( 2.6 ) 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) the recommended dosage in adults and pediatric patients weighing more than 25 kg is one 25 mg tablet once daily taken orally with a meal. ( 2.5 , 12.3 ) Rifabutin coadministration: Take two 25 mg tablets of EDURANT once daily with a meal for the duration of the rifabutin coadministration. ( 2.7 ) 2.1 Overview of Different Dosage Forms EDURANT is available in two dosage forms: EDURANT 25 mg film-coated tablets for adults and pediatric patients weighing at least 25 kg. EDURANT PED 2.5 mg tablets for oral suspension should only be given to pediatric patients weighing at least 14 kg to less than 25 kg [see Dosage and Administration (2.3) ] . Do not substitute EDURANT tablets and EDURANT PED tablets for oral suspension on a milligram-per-milligram basis due to differing pharmacokinetic profiles. A difference in bioavailability between 1 × 25 mg film-coated tablet and 10 × 2.5 mg tablets for oral suspension was observed; therefore, they are NOT substitutable [see Warnings and Precautions (5.6) and Clinical Pharmacology (12.3) ]. Take EDURANT and EDURANT PED once daily with a meal in combination with other antiretrovirals [see Clinical Pharmacology (12.3) ]. 2.2 Recommended Dosage in Treatment-Naïve Adult Patients The recommended dosage of EDURANT in adult patients is one 25 mg tablet taken orally once daily with a meal [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3) ] . 2.3 Recommended Dosage in Treatment-Naïve Pediatric Patients 2 Years of Age and Older and Weighing at least 14 kg The recommended dosage of EDURANT and EDURANT PED in pediatric patients 2 years of age and older and weighing at least 14 kg is based on body weight (see Table 1 ). Both EDURANT and EDURANT PED should be taken orally once daily with a meal [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.3) ] . Table 1: Recommended Dosage of EDURANT and EDURANT PED for Pediatric Patients Body Weight (kg) EDURANT 25 mg Tablets EDURANT PED 2.5 mg Tablets for Oral Suspension Total Daily Dose 14 kg to less than 20 kg Not recommended 5 tablets once daily 12.5 mg EDURANT PED once daily 20 kg to less than 25 kg Not recommended 6 tablets once daily 15 mg EDURANT PED once daily Greater than or equal to 25 kg 1 tablet once daily Not recommended 25 mg EDURANT once daily 2.4 Preparation and Administration Instructions for EDURANT PED Only Advise patients or caregivers of patients taking EDURANT PED to refer to the Instructions for Use to properly prepare and take the medication. EDURANT PED must be dispersed in drinking water and taken immediately with a meal. If not taken immediately, then the oral suspension should be discarded, and a new dose of medicine should be prepared. The patient should not chew or swallow EDURANT PED whole. The following instructions should be followed: Place the tablets for oral suspension in a cup, add 5 mL (1 teaspoon) of drinking water at room temperature. Do not crush the tablets. Swirl the cup carefully for 1–2 minutes to disperse the tablets. The oral suspension will start to look cloudy. Take all the prepared oral suspension immediately or to aid in administration, the oral suspension can be further diluted with 5 mL (1 teaspoon) of drinking water, milk, orange juice or applesauce. Swirl and take all the medicine immediately. A spoon can be used if needed. Make sure the entire dose is taken and no medicine is left in the cup. If required, add another 5 mL (1 teaspoon) of drinking water (or alternative beverage or soft food), swirl and drink immediately. 2.5 Recommended Dosage During Pregnancy 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) the recommended dosage in adults and pediatric patients weighing at least 25 kg is one 25 mg tablet once daily taken orally with a meal. Refer to Table 1 for dosing recommendations for pediatric patients [see Dosage and Administration (2.2 , 2.3) ]. Lower exposures of rilpivirine were observed during pregnancy, therefore viral load should be monitored closely [see Use in Specific Populations (8.1) and Clinical Pharmacology (12.3) ] . 2.6 Recommended Dosage in Com

6 ADVERSE REACTIONS The following adverse reactions are discussed below and in other sections of the labeling: Skin and Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] Hepatotoxicity [see Warnings and Precautions (5.2) ] Depressive Disorders [see Warnings and Precautions (5.3) ] The most common adverse reactions to EDURANT or EDURANT PED (incidence >2%) of at least moderate to severe intensity (≥ Grade 2) were depressive disorders, headache, insomnia and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Janssen Products, LP at 1-800-526-7736 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 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) [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 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.

7 DRUG INTERACTIONS 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 [see Dosage and Administration (2) , Contraindications (4) , and Clinical Pharmacology (12.3) ]. 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 [see Clinical Pharmacology (12.3) ] 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 [see Contraindications (4) ] . Antimycobacterials: rifampin rifapentine ↓ rilpivirine Coadministration is contraindicated with EDURANT or EDURANT PED [see Contraindications (4) ] . 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 [see Contraindications (4) ] . 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 [see Contraindications (4) ] . 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 ot
