Abstract
Background: Black Americans are disproportionately impacted by HIV. The BRAAVE 2020 study, evaluated the safety and efficacy of switching to the guidelines- recommended single- tablet regimen bictegravir, emtricitabine, tenofovir alafenamide (B/F/TAF) in Black adults through week (W) 48.
Method: Adults with HIV self- identifying as Black or African American and virologically suppressed on 2 NRTIs plus a 3rd agent were randomised (2:1) to switch to open- label B/F/TAF once daily or stay on their baseline regimen (SBR). Prior virologic failure was allowed except failure on an INSTI. Prior resistance to NNRTIs, PIs and/or NRTIs was permitted except K65R/E/N, ≥3 thymidine analog mutations or T69- insertions. Primary INSTI- resistance was excluded. SBR participants switched to B/F/TAF at W24. Efficacy was assessed at W24 (Primary endpoint, noninferiority margin 6%) and at W48 as the proportion with HIV- 1 RNA ≥50 c/mL by FDA Snapshot and by changes in CD4 count. Safety was assessed by adverse events (AE) and lab results.
Results: 495 were randomised and treated (B/F/TAF n = 330, SBR n = 165): 32% cis women, 2% transgender women, median age 49 years (range 18– 79) and 10% had pre- existing M184V/I mutation. At W24, 1% (2/328) on B/F/TAF vs 2% (3/165) on SBR had HIV- 1 RNA ≥50 c/mL (difference - 1.2%; 95% CI - 4.8% to 0.9%) demonstrating non-inferiority of B/F/TAF; 2 with pre- existing primary INSTI resistance were excluded from analysis. 163 assigned to SBR completed W24 and switched to B/F/TAF (SBR to B/F/TAF). At W48 1% (3/328) originally randomised to B/F/TAF and 0 SBR to B/F/TAF had HIV- 1 RNA ≥50 c/mL. Baseline NRTI resistance did not affect the efficacy of B/F/TAF. No treatment emergent resistance was detected. Median (IQR) weight increased 0.9 kg (- 1.5, 4.1) and 0.6 kg (- 1.0, 3.1) for B/F/TAF and SBR to B/F/TAF groups, respectively. Study drug- related AEs occurred in 10% of participants while on B/F/TAF; most were grade 1.
Conclusion: Switching to B/F/TAF was highly effective for Black adults regardless of baseline regimen or pre- existing NRTI resistance and was associated with few treatment re-lated AEs or discontinuations.
