Darunavir/Ritonavir + Lamivudine Versus Darunavir/Ritonavir +Emtricitabine/Tenofovir in Naïve HIV-1 Infected Subjects

Summary

The purpose of this study is to compare the safety and efficacy of a combination of a QD regimen consisting on ritonavir boosted darunavir (FDC) and lamivudine versus ritonavir boosted darunavir (FDC) plus co-formulated tenofovir and emtricitabine or co-formulated tenofovir/lamivudine in naïve HIV-1 infected patients. Subjects will be ARV-naïve HIV-1-infected patients eligible to start ARV therapy according to current guidelines.Subjects will be adults ≥ 18 years of age who meet all of the inclusion criteria and none of the exclusion criteria.

Outcome

Met primary endpoint

paper After 48 weeks, 153 patients in the triple therapy group (93%) and 155 patients in the dual therapy group (91%) achieved virological suppression (difference -2.1%, 95% confidence interval -7.0 to 2.9). PMID 39151647 ↗

paper Co-formulated darunavir/ritonavir plus lamivudine showed non-inferiority and a safer toxicity profile compared with the standard-of-care triple therapy regimen including tenofovir in treatment-naïve patients. PMID 39151647 ↗
