Design outcomes
Primary
| Measure | Time 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
| Measure | Time 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 | — |
