Safety and Efficacy of a Switch to Doravirine, Tenofovir, Lamivudine (MK-1439A) in Human Immunodeficiency Virus (HIV-1)-Infected Participants Virologically Suppressed on an Anti-retroviral Regimen in Combination With Two Nucleoside Reverse Transcriptase Inhibitors (MK-1439A-024) (DRIVE-SHIFT)
September 13, 2023 updated by: Merck Sharp & Dohme LLC
A Phase III Multicenter, Open-Label, Randomized Study to Evaluate a Switch to MK-1439A in HIV-1-Infected Subjects Virologically Suppressed on a Regimen of a Ritonavir-boosted Protease Inhibitor and Two Nucleoside Reverse Transcriptase Inhibitors (NRTIs)
The multicenter, open label, randomized study will evaluate the safety and efficacy of a switch to MK-1439A (MK-1439 [doravirine] plus lamivudine and tenofovir disoproxil fumarate) in HIV-1-infected participants virologically suppressed on a protocol-specified antiretroviral regimen.
The primary hypothesis is that a switch to doravirine, tenofovir, lamivudine will be non-inferior to continuation of the regimen at Screening for 24 weeks, as assessed by the proportion of participants maintaining HIV-1 ribonucleic acid (RNA) <50 copies/mL.
The Base Study results will be based on the first 48 weeks of this ongoing study.
