E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
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. |
Evaluar la eficacia de la CDF de B/F/TAF versus DTG + F/TDF frente al VIH y VHB en sujetos no tratados previamente, sujetos coinfectados por VIH-1 y VHB, determinada como la obtención del RNA del VIH-1 <50 copias/ml en la semana 48. Evaluar la eficacia de la CDF de B/F/TAF versus DTG + F/TDF frente al VIH y VHB en sujetos no tratados previamente, sujetos coinfectados por VIH-1 y VHB, determinada como el porcentaje de sujetos con ADN del VHB <29 UI/ml en la semana 48. |
