Background: Older adults living with HIV (OALWH) are a growing population facing unique challenges to successful antiretroviral therapy.Objective: To assess efficacy and safety profiles of antiretroviral regimens, including those containing dolutegravir, in OALWH.Methods: Combined data from 6 phase III/IIIb trials in treatment-naive (ARIA, FLAMINGO, SINGLE, SPRING-2; N = 2634) and treatment-experienced (DAWNING, SAILING; N = 1339) participants receiving dolutegravir- or non-dolutegravir-based regimens were analyzed by age (<50, ≥50 to <65, and ≥65 years). Baseline data included comorbidities and numbers of concomitant medications. Week 48 efficacy outcomes included virologic response (HIV-1 RNA <50 copies/mL) and CD4+ cell count change from baseline. Safety outcomes included incidence of adverse events (AEs), serious AEs, and AE-related withdrawals.Results: Use of ≥5 concomitant medications was more frequently reported among treatment-naive and treatment-experienced participants aged ≥50 to <65 (30% [90/296] and 25% [57/227], respectively) and ≥65 years (43% [10/23] and 29% [4/14]) than among those aged <50 years (13% [310/2315] and 11% [118/1098]). Comorbidities were more prevalent in the older age groups. For dolutegravir-based regimens, Week 48 rates of virologic response and change in CD4+ cell count were similar across age groups (treatment naive, 80-87% and 234-251 cells/mm3; treatment experienced, 70-100% and 105-156 cells/mm3, respectively). There were no major differences in safety outcomes in each age group.Conclusions: In these analyses of combined phase III/IIIb trial data, efficacy and safety of dolutegravir-based regimens were generally similar across age groups in treatment-naive or treatment-experienced participants. Polypharmacy and comorbidities were more common among OALWH than those aged <50 years.
