The US Food and Drug Administration (FDA) has approved Gilead Sciences’ Descovy (emtricitabine 200 mg/tenofovir alafenamide 25 mg, F/TAF), a fixed-dose combination for the treatment of HIV. Descovy is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in adults and pediatric patients 12 years of age and older.

TAF is a targeted prodrug of tenofovir that has demonstrated high antiviral efficacy similar to and at a dose less than one-tenth that of Gilead's Viread (tenofovir disoproxil fumarate, TDF). TAF has also demonstrated improvement in surrogate laboratory markers of renal and bone safety as compared to TDF in clinical trials in combination with other antiretroviral agents. Data show that because TAF enters cells, including HIV-infected cells, more efficiently than TDF, it can be given at a much lower dose and there is 90% less tenofovir in the bloodstream.
