Doravirine exposure and HIV-1 suppression after switching from an efavirenz-based regimen to doravirine-lamivudine-tenofovir disoproxil fumarate

Abstract

Doravirine is a nonnucleoside reverse transcriptase inhibitor that has been approved for the treatment of HIV-1. In a phase 1 trial, doravirine exposure was transiently decreased when treatment was started immediately after the cessation of efavirenz treatment. In a post hoc subgroup analysis of participants who switched from an efavirenz-based regimen to doravirine-lamivudine-tenofovir disoproxil fumarate in the phase 3 DRIVE-SHIFT trial, doravirine plasma levels at week 4 were similar to noninduced levels, and HIV-1 suppression was maintained at weeks 24 and 48.
