ABSTRACT
OBJECTIVE:
To evaluate the efficacy and safety of antiretroviral simplification from a ritonavir-boosted protease inhibitor-based regimen [protease inhibitor+RTV+two nucleos(t)ide reverse transcriptase inhibitors (NRTIs); ≥6 months of exposure prior to study entry with no prior treatment failure] to the single-tablet regimen (STR) rilpivirine/emtricitabine/tenofovir disoproxil fumarate (RPV/FTC/TDF) in virologically suppressed, HIV-1-infected participants.DESIGN:
Phase 3b, randomized, open-label, international, 48-week switch study.METHODS:
Participants were randomized 2ââ1 to switch to RPV/FTC/TDF immediately or stay on their baseline protease inhibitor+RTV+2NRTIs regimen with a delayed switch to RPV/FTC/TDF at week 24. The primary endpoint was noninferiority (12% margin) of RPV/FTC/TDF compared with protease inhibitor+RTV+ two NRTIs in maintaining plasma HIV-1 RNA less than 50âcopies/ml at week 24 by Snapshot analysis.RESULTS:
A total of 476 participants were randomized and received at least one dose of study drug. Demographics and baseline characteristics were similar between arms. The primary objective of noninferiority at week 24 was met HIV-1 RNA less than 50âcopies/ml by Snapshot analysis, 93.7% of RPV/FTC/TDF versus 89.9% of protease inhibitor+RTV+ two NRTIs (difference 3.8%, 95% confidence interval -1.6 to 9.1%). Through week 48, 89.3% of participants in the immediate switch group maintained virologic suppression. High rates of suppression were maintained with RPV/FTC/TDF regardless of participant's pre-antiretroviral HIV-1 RNA level. Overall development of resistance mutations after switching to RPV/FTC/TDF was low. Decreases in total cholesterol, low-density lipoprotein (LDL), and triglycerides were significantly greater among RPV/FTC/TDF recipients than those in the protease inhibitor+RTV+ two NRTIs group.CONCLUSION:
Switching to the STR RPV/FTC/TDF from an RTV-boosted protease inhibitor regimen in virologically suppressed, HIV-1-infected participants maintained virologic suppression with a low risk of virologic failure, while improving total cholesterol, LDL, and triglycerides.
