Efficacy of Rilpivirine-based Regimens as Switch Therapy From Nevirapine-based Regimens in HIV-infected Patients

Summary

Background: Nevirapine (NVP)-based antiretroviral therapy (ART) remains to be used in HIV-infected patients in resource limited countries despite its compliance and adverse effect concerns. Rilpivirine (RPV), a newer non-nucleoside reverse transcriptase inhibitor, could be used as an alternative to NVP in virologically suppressed patients. However, there has been limited experience with switching from NVP-based to RPV-based regimens. The investigators aimed to study efficacy and adverse events after ART switching from NVP-based to RPV-based regimens. Methods: A randomized controlled non-inferiority trial was conducted in HIV-infected patients who received NVP-based regimens and had undetectable plasma HIV RNA for more than 6 months. Patients were randomized 1:1 to continuation arm (NVP-based regimens were continued) or switch arm (NVP-based regimens were switched to RPV-based regimens). Tenofovir disoproxil fumarate (TDF) plus lamivudine (3TC) or emtricitabine (FTC) remained as the backbone of the regimens. Primary endpoint was HIV RNA \<40 copies/mL at 48 weeks, with a non-inferiority margin of 12%. Changes of CD4 cell counts and lipid profiles from baseline were analyzed.
