Study summary

The goal of this pilot, phase 2, single-arm, clinical trial is to assess the antiretroviral combination Doravirine (DOR)/Lamivudine (3TC)/Tenofovir Disproxyl Fumarate (TDF) in participants with suppressed HIV who previously developed M184V/I mutation that confers resistance to 3TC. The main question it aims to answer is to explore the rate of HIV suppression 24 weeks after the switch to DOR/3TC/TDF. The study follow-up will continue until 48 weeks. Other endpoints will be metabolic changes, weight changes, modification in the HIV-DNA mutations overtime. Eligible participants will switch from their prior regimen to DOR/3TC/TDF with careful HIV-RNA monitoring.
