Long-term efficacy of dolutegravir plus lamivudine for maintenance of HIV viral suppression in adults with and without historical resistance to lamivudine: Week 96 results of ART-PRO pilot study

Background: In the ART-PRO pilot trial there were no virological failures through 48 weeks of treatment with dolutegravir plus lamivudine in suppressed individuals with and without archived lamivudine resistance-associated mutations (RAMs) detected through next-generation sequencing (NGS) but without evidence of lamivudine RAMs in baseline proviral DNA population sequencing. Objectives: To present 96 week results from ART-PRO. Methods: Open-label, single-arm pilot trial. At baseline, all participants switched to dolutegravir plus lamivudine. Participants were excluded if proviral DNA population genotyping detected lamivudine RAMs. To detect resistance minority variants, proviral DNA NGS was retrospectively performed from baseline samples. For this analysis the efficacy endpoint was the proportion of participants with
