Warning

Oral route (Tablet)

Emtricitabine/rilpivirine/tenofovir alafenamide is not approved for the treatment of chronic hepatitis B virus (HBV) infection and the safety and efficacy of emtricitabine/rilpivirine/tenofovir alafenamide have not been established in patients coinfected with human immunodeficiency virus-1 (HIV-1) and HBV. Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine (FTC) and/or tenofovir disoproxil fumarate (TDF), and may occur with emtricitabine / rilpivirine / tenofovir alafenamide. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several moths in patients who are coinfected with HIV-1 and HBV and discontinue emtricitabine / rilpivirine / tenofovir alafenamide. If appropriate, initiation of antihepatitis B therapy may be warranted.

General

The most common side effects reported with emtricitabine / rilpivirine / tenofovir alafenamide in virologically-suppressed patients with HIV-1 infection were headache and sleep disturbances.

During clinical studies, antiretroviral therapy-naive patients received rilpivirine in combination with emtricitabine-tenofovir disoproxil fumarate (DF). The most common side effects were depression/depressive disorders, nausea, dizziness, abnormal dreams, headache, diarrhea, and insomnia. In virologically-suppressed patients switching to emtricitabine/rilpivirine/tenofovir DF, the most common side effects were fatigue, diarrhea, nausea, and insomnia.

In 1 trial, baseline eGFR averaged 104 mL/min for patients who switched to emtricitabine / rilpivirine / tenofovir alafenamide from emtricitabine/rilpivirine/tenofovir DF; serum creatinine decreased by 0.02 mg/dL from baseline to week 48. In another trial, baseline eGFR averaged 110 mL/min for patients who switched to emtricitabine / rilpivirine / tenofovir alafenamide from emtricitabine/rilpivirine/tenofovir DF; serum creatinine increased by 0.1 mg/dL from baseline to week 48.

Increased creatinine (grade 1: 6%; grade 2: 1%; grade 3: less than 1%) has been reported with emtricitabine-tenofovir DF plus rilpivirine.

During phase 3 trials, an increase in serum creatinine and decrease in eGFR were seen over 96 weeks of therapy with rilpivirine. Most of these changes occurred within the first 4 weeks of therapy, with a mean change of 0.1 mg/dL (range: -0.3 to 0.6 mg/dL) for creatinine and -13.3 mL/min/1.73 m2 (range: -63.7 to 40.1 mL/min/1.73 m2) for eGFR observed after 96 weeks of therapy. In subjects with mild or moderate baseline renal dysfunction, the serum creatinine increase observed was similar to that seen in subjects with normal renal function. These changes were not considered clinically relevant and no subject discontinued therapy due to increases in serum creatinine.

Proximal renal tubulopathy generally resolved or improved after tenofovir DF was stopped; however, decreased CrCl did not completely resolve in some patients after stopping the drug. Rhabdomyolysis, osteomalacia, bone abnormalities (infrequently contributing to fractures), hypokalemia, muscular weakness, myopathy, and hypophosphatemia have occurred as a result of proximal renal tubulopathy.[Ref]

In the pooled phase 3 trials, at week 96, there was an overall mean change from baseline in basal cortisol of -19.1 nmol/L (-0.69 mcg/dL) in the rilpivirine group, and of -0.6 nmol/L (-0.02 mcg/dL) in the efavirenz group. At week 96, the mean change from baseline in ACTH-stimulated cortisol levels was lower in the rilpivirine group (+18.4 nmol/L) than in the efavirenz group (+54.1 nmol/L). Mean values for both basal and ACTH-stimulated cortisol values at week 96 were within the normal range.

In the rilpivirine group, 43 of 588 patients with normal 250 mcg ACTH stimulation test at baseline developed abnormal 250 mcg ACTH stimulation test (peak cortisol level less than 18.1 mcg/dL) during the trial versus 18 of 561 patients in the efavirenz group. Abnormal 250 mcg ACTH stimulation test at week 96 was seen in 14 of the 43 rilpivirine patients and 9 of the 18 efavirenz patients. Clinical significance of abnormal 250 mcg ACTH stimulation tests (or the higher rate in the rilpivirine group) has not been established.

Overall, there were no serious side effects, deaths, or treatment discontinuations that could clearly be attributed to adrenal insufficiency.[Ref]
