Clinical Trial Summary

To evaluate the safety and efficacy of bictegravir/emtricitabine/tenofovir alafenamide versus tenofovir disoproxil fumarate-based antiretroviral regimens in HIV-infected individuals with virological suppression.

Description:

This study is a multicenter, randomized, controlled, open labeled clinical trial, which aims to evaluate the safety and efficacy of B/F/TAF versus TDF-based antiretroviral therapy in HIV-infected individuals with virological suppression, and to evaluate the changes in quality of life and adherence after switching from a TDF-based regimen to B/F/TAF in HIV-infected individuals with virological suppression.

Intervention

Drug:
• B/F/TAF
Bictegravir/emtricitabine/tenofovir alafenamide once daily, 1 tablet at a time, with or without food for 48 weeks.
• TDF-based triple ART regimen switching to B/F/TAF
Tenofovir disoproxil fumarate was administered once daily, one tablet at a time, with or without food. After Week 24, control subjects were also switched to bictegravir/emtricitabine/tenofovir alafenamide once daily, one tablet at a time, with or without food for the later 24 weeks.
