Safety, efficacy, and pharmacokinetics of a single-tablet regimen containing elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide in treatment-naive, HIV-infected adolescents: a single-arm, open-label trial.

Background: The prodrug tenofovir alafenamide is associated with improved renal and bone safety compared with tenofovir disoproxil fumarate. We aimed to assess safety, pharmacokinetics, and efficacy of this single-tablet, fixed-dose combination of elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide in HIV-infected, treatment-naive adolescents.

Methods: We did a 48 week, single-arm, open-label trial in treatment-naive adolescents with HIV from ten hospital clinics in South Africa, Thailand, Uganda, and the USA.
