Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of tenofovir alafenamide (TAF) versus placebo, each administered with the existing, failing antiretroviral regimen, as demonstrated by the proportion of subjects with HIV-1 RNA decreases from baseline exceeding 0.5 log10 after 10 days of therapy in HIV-1 positive, antiretroviral treatment experienced adult subjects.;Secondary Objective: To evaluate the efficacy of TAF as demonstrated by the reduction in HIV-1 RNA at Day 10 To evaluate the efficacy and safety of elvitegravir/ cobicistat/ emtricitabine/ tenofovir alafenamide single tablet regimen (E/C/F/TAF STR) plus atazanavir after 24 weeks of treatment in subjects switched from a failing regimen as determined by the achievement of plasma HIV-1 RNA <50 copies/mL. To evaluate the efficacy and safety of E/C/F/TAF STR plus atazanavir after 48 weeks of treatment in subjects switched from a failing regimen.;Primary end point(s): The proportion of subjects with plasma HIV-1 RNA decreases from baseline exceeding 0.5 log10 at Day 10 in Part 1.;Timepoint(s) of evaluation of this end point: Day 10 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): -The change from baseline in plasma log10 HIV-1 RNA (copies/mL) at Day 10 in Part 1. -The percentage of subjects with plasma HIV-1 RNA < 50 copies/mL as defined by the FDA snapshot analysis at Weeks 24 and 48. -The percentage of subjects with plasma HIV-1 RNA < 400 copies/mL as defined by the FDA snapshot analysis at Weeks 24 and 48. -The change from baseline in plasma log10 HIV-1 RNA (copies/mL) and in CD4+ cell count (cells/µL) and percentage at Week 24. -The change from baseline in plasma log10 HIV-1 RNA (copies/mL) and in CD4+ cell count (cells/µL) and percentage at Week 48. -The safety of E/C/F/TAF STR plus ATV in subjects switched from a failing regimen after 24 and 48 weeks of treatment as assessed by laboratory parameters and adverse events during the study. -The following PK parameters of TAF, TFV, EVG and ATV will be calculated for subjects in the intensive PK substudies, as appropriate: AUClast , Clast and Cmax for TAF and AUCtau, Ctau, and Cmax for TFV, EVG and ATV.;Timepoint(s) of evaluation of this end point: Day 10 week 48 | — |
