Efficacy and Safety of E/C/F/TAF (Genvoya®) in HIV-1/Hepatitis B Co-infected Adults

19 de outubro de 2018 atualizado por: Gilead Sciences

A Phase 3b Open-label Study of the Efficacy and Safety of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide Single-Tablet Regimen in HIV-1/Hepatitis B Co-infected Adults

This study will assess the efficacy, safety, and tolerability of elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) fixed-dose combination (FDC) in human immunodeficiency virus (HIV)/hepatitis B virus (HBV) coinfected adults.

Participants will be enrolled into two cohorts:

  • Cohort 1: HIV/HBV coinfected adults who are HIV treatment-naive and HBV treatment-naive
  • Cohort 2: HIV/HBV coinfected adults who are HIV-suppressed
