  • Switching to RPV/FTC/TAF from RPV/FTC/TDF or EFV/FTC/TDF was effective
    • High rates of virologic suppression
    • No emergent resistance mutations on RPV/FTC/TAF
  • RPV/FTC/TAF was well tolerated
    • Low rate of adverse events
    • Low rate of discontinuation
  • RPV/FTC/TAF provided improved renal and bone safety
    • Decreased total and tubular proteinuria (p < 0.001)
    • No proximal tubulopathy
    • Increased BMD at hip and spine (p < 0.001)

Design

Objective

  • Primary Endpoint: proportion with treatment success at W48 (HIV RNA < 50 c/mL, ITT- FDA snapshot)

Baseline characteristics

HIV-1 RNA < 50 c/mL at W48 (ITT, FDA snapshot)

Adverse events, % (≥ 5% in either group)

Adverse events leading to discontinuation, N (%)

Grade 3-4 laboratory abnormalities, %

Median change in eGFR [ Cockroft-Gault ] (mL/min) at W48 (Q1-Q3)

Change in Proteinuria at W48 (median % change)

  • All differences (RPV/F/TAF vs RPV/F/TDF or EFV/F/TDF) : p < 0.001 ; no reported cases of tubulopathy

Median % change in Hip BMD through W48 (95% CI)

Median % change in Spine BMD through W48 (95% CI)

Median fasting lipids (mg/dL) at baseline and W48

Median fasting lipids (mg/dL) at baseline and W48
