• Over 48 weeks, in virologically suppressed patients with high cardiovascular risk (older than 50 years and/or with a Framingham score > 10%) and receiving triple therapy with PI/r + 2 NRTIs
  • Switching to a DTG regimen was non-inferior. Sensitivity and subgroup analysis support this conclusion
  • Improved total cholesterol and other lipid fractions in the overall population and in several subgroups
  • Very few episodes of confirmed virological failure and no resistance mutations selected
  • Overall tolerance was good and similar in both arms

Design

Primary endpoints

• – Proportion of patients with virological success at W48 (no consecutive HIV-1 RNA > 50 c/mL and no treatment discontinuation): non-inferiority of DTG, by ITT, Kaplan-Meier analysis; lower limit of the 95% CI for the difference = - 10%, power 90%
• Mean percentage changes in fasting lipid total cholesterol at W48 (between treatment difference of 12%, 99% power)

Baseline characteristics and patient disposition

CV risk factors and ARV therapy at screening

Outcome at W 48, ITT

• Confirmed virological failure (HIV RNA > 50 c/mL): DTG, N = 4 vs PI/r, N = 1 ; genotype successful in 2/4 and 0/1 patients: no emergence of resistance mutations

Treatment success at W48 (ITT, per- protocol and sub -groups)

Fasting plasma lipids ( mmol /L): mean percentage change at W48

• No changes in the utilization of lipid lowering agents (around 30% in each arm, both at baseline and W48)

Adverse events, %

* Acute HCV infection (N = 1), mood and/or sleep disorders (N = 6)
** Acute HCV infection (N = 1), dyspepsia (N = 1), worsening of renal function (N = 1)

Median change in eGFR (CKD-EPI) at W48 (p < 0.001)

• ‒ DTG: ~ - 8 ml/min
• PI/r: 0 ml/min
