The US FDA has approved Gilead’s Descovy (emtricitabine/tenofovir alafenamide) as a second pre-exposure prophylaxis (PrEP) drug in at-risk adults and adolescents weighing at least 75lbs for the prevention of HIV infection.
The safety and efficacy of the drug were evaluated in the randomised, double-blind multinational DISCOVER trial in 5387 HIV-negative men and transgender women who have sex with men. The trial compared the once-daily Descovy to Truvada.
