This study will test a United States Food and Drug Administration (FDA) approved drug named bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) fixed dose combination (FDC) for the treatment of HIV-1. This drug has been approved as Biktarvy® in the United States in February 2018. The purpose of this study is to test the effectiveness of B/F/TAF FDC against HIV-1 and Hepatitis B in subjects not currently receiving treatment for their HIV-1 and HBV infection, compared to DTG + F/TDF.

A Phase 3, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Fixed Dose Combination of Bictegravir/Emtricitabine/Tenofovir Alafenamide versus Dolutegravir + Emtricitabine/Tenofovir Disoproxil Fumarate in Treatment Naïve, HIV-1 and Hepatitis B Co-Infected Adults

Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the efficacy of B/F/TAF FDC versus a DTG + F/TDF in HIV and HBV treatment naïve, HIV-1 and HBV co-infected subjects as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 48. To evaluate the efficacy of FDC of B/F/TAF versus DTG + F/TDF in HIV and HBV treatment naïve, HIV-1 and HBV co-infected subjects as determined by the proportion of subjects with plasma HBV DNA < 29 IU/mL at Week 48.;Secondary Objective: To evaluate the efficacy of FDC of B/F/TAF versus DTG + F/TDF as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 96. To evaluate the efficacy of FDC of B/F/TAF versus DTG + F/TDF as determined by the proportion of subjects with plasma HBV DNA < 29 IU/mL at Week 96.;Primary end point(s): - The proportion of subjects that have HIV-1 RNA < 50 copies/mL at Week 48 as defined by the US FDA-defined snapshot algorithm - The proportion of subjects with plasma HBV DNA < 29 IU/mL at Week 48 by Missing = Failure approach ;Timepoint(s) of evaluation of this end point: Week 48

Secondary

MeasureTime frame
Secondary end point(s): Secondary anti-HIV efficacy endpoints: - The proportion of subjects that have HIV-1 RNA < 50 copies/mL at Week 96 - The change from baseline in CD4 cell count and CD4% at Weeks 48 and 96 Secondary anti-HBV efficacy endpoints: - The proportion of subjects with plasma HBV DNA < 29 IU/mL at Week 96 - The proportion of subjects with ALT normalization at Weeks 48 and 96 - The proportion of subjects with HBsAg loss at Weeks 48 and 96;Timepoint(s) of evaluation of this end point: Weeks 48 and 96
