2490. Longer-Term Safety and Efficacy of Elvitegravir/Cobicistat/Emtricitabine/Tenofovir Alafenamide in Virologically Suppressed Adults Living With HIV and End-Stage Renal Disease on Chronic Hemodialysis

BACKGROUND: HIV treatment for individuals with end-stage renal disease (ESRD) on hemodialysis (HD) has previously required complex dose-adjusted regimens. We evaluated the safety and efficacy of single-tablet, once-daily elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) in people living with HIV (PLH) and ESRD on chronic HD. METHODS: Virologically suppressed adult PLH with ESRD on chronic HD for ≥ 6 months were switched to open-label E/C/F/TAF 150/150/200/10 mg once daily for 96 weeks. Efficacy was assessed as the proportion of participants who maintained virologic suppression (HIV RNA < 50 copies/mL) using the snapshot algorithm. Safety and participant satisfaction were assessed throughout the study. RESULTS: We enrolled 55 participants with median age 51 years (range 23–64) with median time on HD 6 years (range 1–17). In the per protocol analysis set, virologic suppression was maintained in 30 of 31 participants (96.8%, 95% CI [83.3%, 99.9%]) at week 96. In the full analysis set, virologic suppression was maintained in 30 of 55 participants (54.5%; 95% CI [40.6%, 68.0%]); one discontinued therapy due to lack of efficacy, and W96 data were unavailable for 24. Of the 24 participants lacking W96 data, 17 discontinued study drug early and 7 had missing data while on study drug; all had HIV RNA < 50 copies/mL at the last pre-week 96 check. Treatment-emergent AEs occurred in 53 (96.4%) participants, and study-drug-related AEs occurred in 7 (12.7%). Treatment-emergent AEs leading to premature study drug discontinuation occurred in 4 (7.3%) participants; two were considered study-drug-related (allergic pruritus and peripheral neuropathy in one participant each). No study-drug-related serious AEs were observed. 85.7% (30/35) of responding participants reported they were ‘much more satisfied’ with their regimen. CONCLUSION: Single-tablet, once-daily E/C/F/TAF was effective in maintaining virologic suppression in PLH on chronic HD over 96 weeks of follow-up. E/C/F/TAF was well tolerated and was associated with improved participant satisfaction. These data demonstrate that E/C/F/TAF is a safe and effective alternative to more complicated regimens in PLH on chronic HD, with the potential to improve patient satisfaction and quality of life.
