Revisiting efavirenz in the era of dolutegravir: Low-dose efavirenz, a viable alternative capable of holding its own against dolutegravir-based regimens
Background: First-line dual NRTI + NNRTI-based ART has shown good virological effectiveness; however, toxicity is common and is often the most common reason for modification of first-line ART. Aims: The purpose of this study is to revisit low-dose efavirenz (EFV) in the era of dolutegravir (DTG) by investigating anti-retroviral therapy (ART) switch strategies for outcomes of virological effectiveness and safety in virologically suppressed Indian persons living with HIV (PLH) on first-line dual nucleoside reverse transcriptase inhibitors (NRTI) + non-NRTI (NNRTI)-based ART. Methods: A phase-IV comparative study of consecutive cases who switched their first-line NNRTI-based ART to either EFV-400 or DTG with a dual NRTI backbone between October 2020 to December 2021 and underwent at least 48 weeks of follow-up. The study is a non-randomised trial, wherein ART regimens were based on physician choice, patient preference and drug availability. Results: A total of 102 [DTG arm: 52; EFV-400 arm: 50; intention-to-treat (ITT) population] participants met the inclusion criteria.
