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.

Arms and Interventions

Arm Intervention/Treatment
Other: B/F/TAF

Switching participants who are currently on multi-tablet HIV antiretroviral therapy, including multi-tablet regimens and/or two drug combinations (dual therapy) to one oral tablet of B/F/TAF once-daily for 72 weeks

Drug: Bictegravir/emtricitabine/tenofovir alafenamide
Taking one oral tablet of B/F/TAF once-daily for 72 weeks

Outcome Measures

Primary Outcome Measures

  1. 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

  1. 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

  2. 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

  3. Proportion of patients that achieved >90% adherence [Analysis will be done at 72 weeks]

    Proportion of patients that achieved >90% adherence

  4. 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

  5. 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

  6. 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
