Switching to a Fixed Dose Combination of Bictegravir/Emtricitabine/Tenofovir Alafenamide (B/F/TAF) in HIV-1 Infected Marginalized Populations Who Are Virologically Suppressed
Study Details
Study Description
Brief Summary
In an effort to engage more HIV-infected PWUD into care, and ensure treatment adherence and efficacy, simplification of older, multi-tablet regimens is required. Newer, more potent molecules can also overcome resistant that has persisted with previous regimens, while simultaneously providing a high barrier to resistance. The co-formulation of B/F/TAF is a viable switch-option for patients who have experienced lower adherence with previous regimens due to high pill burden, or for those requiring a more potent regimen due to emergent resistances. The formal evaluation of B/F/TAF in this context will allow us to optimize care for HIV-infected PWUD.

Outcome Measures
Primary Outcome Measures
- The proportion of subjects that remain virally suppressed at week 48 [Interim analysis of efficacy will be done at 24 weeks]
The proportion of subjects with HIV RNA <40 copies/mL
Secondary Outcome Measures
- The proportion of subjects with viral blips [Analysis will be done at 72 weeks]
Viral blips defined as detectable HIV viral load between 40-1000 copies/mL at week 72
- Changes of adherence [Analysis will be done at 72 weeks]
Changes of adherence from baseline at week 2, 8, 24, 48, and 72 with an adherence questionnaire
- Proportion of patients that achieved >90% adherence [Analysis will be done at 72 weeks]
Proportion of patients that achieved >90% adherence
- The proportion of viral blips on regimens pre-switch compared to the blips on B/F/TAF [Analysis will be done at 72 weeks]
The proportion of viral blips on regimens pre-switch compared to the blips on B/F/TAF
- The proportion of participants that discontinued B/F/TAF due to side-effects at weeks 36 and72 [Analysis will be done at 72 weeks]
The proportion of participants that discontinued B/F/TAF due to side-effects at weeks 36 and72
- Changes to baseline quality of life at week 4, 12, 36, 60, and 72 using the HIV Symptoms Distress Module [Analysis will be done at 72 weeks]
Changes to baseline quality of life at week 4, 12, 36, 60, and 72 using the HIV Symptoms Distress Module
