Phase IIb, Double-Blinded, Multicenter, Randomized Study to Assess the Effect on Central Nervous System (CNS) Toxicity of Switching From ATRIPLA™ (Efavirenz, Tenofovir, Emtricitabine) to MK-1439A (Doravirine, Tenofovir, Lamivudine) in Virologically-Suppressed Subjects.
In Brief
A Phase 2 clinical trial evaluating Doravirine, Tenofovir, Lamivudine - Blinded, Doravirine, Tenofovir, Lamivudine - Open-Label, and 3 other interventions for HIV-1 and Central Nervous System. Completed, enrolled 86 participants.
Detailed Summary
This study aims to evaluate a switch from fixed dose combination (FDC) treatment with ATRIPLA\^TM for 12 weeks prior to screening to FDC treatment with Doravirine, Tenofovir, Lamivudine (MK-1439A) in virologically-suppressed, human immunodeficiency virus type 1 (HIV-1)-infected participants. The primary hypothesis is that switching from ATRIPLA\^TM to Doravirine, Tenofovir, Lamivudine results in a lower proportion of participants with at least one CNS toxicity of at least Grade 2 intensity at Week 12 than continuation of ATRIPLA\^TM treatment.
