Abstract
Objective. Evaluation of the efficacy and safety of elsulfavirine (ESV)-based antiretroviral therapy (ART) regimens in HIV-infected patients switched from effective ART regimens due to adverse events (PRIB-2).
Materials and methods. The PRIB-2 study was conducted at 22 research centers in the Russian Federation and included 724 patients receiving effective ART containing ESV or protease inhibitors. Due to intolerance to their current ART regimen, all participants were switched to an ESV-based regimen and a backbone therapy consisting of two HIV nucleoside reverse transcriptase inhibitors (NRTIs). The follow-up period was 96 weeks. Efficacy was assessed in 447 patients receiving first-line ART regimens: ESV + TDF + 3TC (or FTC) and ESV + ABC + 3TC (or FTC), while safety was assessed in all study participants.
Results. The virological and immunological efficacy of the studied first-line ART regimens was demonstrated. It was found that after 48 weeks of treatment, undetectable HIV RNA levels were recorded in 93.8–94.0% of patients, and in 96.3–100.0% of patients, respectively. The median increase in CD4+ lymphocyte count after 48 weeks was 41.0 cells/μL, and after 96 weeks, 87.0 cells/μL. A favorable safety profile was demonstrated for ESV-based ART regimens. Adverse reactions (ARs) associated with ESV were reported in 21.6% of cases, 99.0% of which were mild or moderate. ARs of particular interest accounted for 26.1% of all ARs. No life-threatening or fatal ARs were reported. Switching from effective ART regimens to ART regimens containing ESV resulted in no negative changes in virological and immunological responses, with a more favorable safety profile.
Conclusion. An ART regimen containing ESV and two NRTIs can be recommended for patients with HIV infection receiving effective ART regimens with safety and/or tolerability concerns.
