Abstract
OBJECTIVE: This study evaluated rates of treatment-emergent resistance-associated mutations (TE-RAMs) and discontinuation due to adverse events (DC-AEs) across integrase strand transfer inhibitor (INSTI)-based single-tablet regimens and injectable cabotegravir + rilpivirine (CAB + RPV) in virologically suppressed people with HIV.
METHODS: A systematic literature review was conducted for phase 2-4 randomized controlled trials with ≥ 48 weeks of follow-up involving virologically suppressed people with HIV aged ≥ 12 years and published January 2003-March 2024. A random-effects network meta-analysis estimated comparative rates of TE-RAMs and DC-AEs among regimens at 48 weeks. Risk of bias and strength of evidence were assessed using Cochrane RoB and CINeMA, respectively.
RESULTS: Fourteen (7509 participants) and nine (4656 participants) studies were included in the TE-RAMs and DC-AEs analyses, respectively. No significant differences in rates of TE-RAMs were observed; risk ratios (RRs) for TE-RAMs for bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF), dolutegravir/abacavir/lamivudine (DTG/ABC/3TC) and CAB + RPV every 4 weeks (Q4W) versus CAB + RPV every 8 weeks (Q8W) were 0.22 (95% CI, 0.02-2.04), 0.22 (95% CI, 0.00-19.85) and 0.40 (95% CI, 0.14-1.09). Compared with CAB + RPV Q4W and Q8W, DC-AEs were significantly lower with B/F/TAF (RR, 0.15 [95% CI, 0.03-0.75] and RR, 0.16 [95% CI, 0.04-0.67], respectively) and DTG/ABC/3TC (RR, 0.05 [95% CI, 0.01-0.48] and RR, 0.05 [95% CI, 0.01-0.46], respectively).
CONCLUSIONS: In virologically suppressed people with HIV, switching to CAB + RPV Q8W yielded a non-significant increased risk of TE-RAMs compared with INSTI-based 2- and 3-drug regimens and CAB + RPV Q4W. Both CAB + RPV Q4W and Q8W had significantly higher risks of DC-AEs than B/F/TAF and DTG/ABC/3TC. Findings highlight the importance of considering both resistance and tolerability when switching regimens.
