emtricitabine, rilpivirine and tenofovir disoproxil fumarate

Clinical summary

Indications and usage 1 INDICATIONS AND USAGE Emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets are indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 35 kg: • as initial therapy in those with no antiretroviral treatment history with HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy or • to replace a stable antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable antiretroviral regimen for at least 6 months with no treatment failure and no known substitutions associated with resistance to the individual components of emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets [see Microbiology (12.4) and Clinical Studies (14) ]. Limitations of Use: • More rilpivirine-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 rilpivirine-treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL [see Clinical Studies (14) ]. Emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, a combination of two nucleoside analog HIV-1 reverse transcriptase inhibitors (emtricitabine and tenofovir disoproxil fumarate) and one non-nucleoside reverse transcriptase inhibitor (rilpivirine), is indicated for use as a complete regimen for the treatment of HIV-1 infection in patients weighing at least 35 kg (1) as initial therapy in those with no antiretroviral treatment history and with HIV-1 RNA less than or equal to 100,000 copies/mL at the start of therapy, or (2) or to replace a stable antiretroviral regiment in those who are virologically suppressed (HIV-1 RNA <50 copies/mL) on a stable antiretroviral regimen for at least 6 months with no treatment failure and no known substitutions associated with resistance to the individual components of emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets. ( 1 , 14 ) Limitations of Use: • More rilpivirine-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 rilpivirine-treated subjects with HIV-1 RNA less than or equal to 100,000 copies/mL. ( 1 , 14 ) Dosage and administration 2 DOSAGE AND ADMINISTRATION • Testing: Prior to or when initiating emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, test for hepatitis B virus infection. Prior to initiation and during treatment with emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. ( 2.1 ) • Recommended dosage in adults and pediatric patients weighing at least 35 kg: One tablet taken orally once daily with food. ( 2.2 ) • For pregnant patients who are already on emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets prior to pregnancy and who are virologically suppressed (HIV-1 RNA less than 50 copies per mL), one tablet taken once daily may be continued. Lower exposures of rilpivirine were observed during pregnancy; therefore, viral load should be monitored closely. ( 2.3 ) • Renal impairment: Not recommended in patients with estimated creatinine clearance below 50 mL per minute. ( 2.4 ) • Recommended dosage with rifabutin coadministration: an additional 25 mg tablet of rilpivirine (Edurant) once per day taken concomitantly with emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets and with a meal for the duration of the rifabutin coadministration. ( 2.5 , 7.6 , 12.3 ) 2.1 Testing Prior to Initiation and During Treatment with Emtricitabine, Rilpivirine and Tenofovir Disoproxil Fumarate Tablets Prior to or when initiating emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, test patients for hepatitis B virus infection [see Warnings and Precautions (5.1) ]. Prior to initiation of emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, and during treatment with emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets, on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus [see Warnings and Precautions (5.5) ]. 2.2 Recommended Dosage Emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets are a three-drug fixed dose combination product containing 200 mg of emtricitabine (FTC), 25 mg of rilpivirine (RPV), and 300 mg of tenofovir disoproxil fumarate (TDF). The recommended dosage of emtricitabine, rilpivirine and tenofovir disoproxil fumarate tablets in adult and pediatric patients weighing at least 35 kg is one tablet taken orally once daily with
