Switching from a Ritonavir-Boosted Protease Inhibitor to a Dolutegravir-Based Regimen for Maintenance of HIV Viral Suppression in Patients with High Cardiovascular Risk

Résumé

Objective: To compare the efficacy, safety, and impact on lipid fractions of switching from a ritonavir-boosted protease inhibitor (PI/r) to a dolutegravir (DTG) regimen. Methods: HIV type 1-infected adults more than 50 years or with a Framingham score more than 10% were eligible if plasma HIV RNA less than 50 copies per ml for at least 24 weeks while on a PI/r regimen. Patients were randomized to switch to DTG or to remain on PI/r. Primary endpoints were: proportion maintaining HIV RNA less than 50 copies per ml and percentage change from baseline of total cholesterol at week 48. Results: In total, 415 patients (32 sites in six European countries) were randomized: 205 to DTG and 210 to continue PI/r. About 89% were men, 87% more than 50 years, 74% had a Framingham score more than 10%, with a median CD4 cell count of 617 cells per μl and suppressed viremia for a median of 5 years. At week 48, in the intent-to-treat analysis, treatment success rate was 93.1% in DTG group and 95.2% in PI/r group (difference -2.1%, 95% confidence interval -6.6 to 2.4, noninferiority demonstrated). There were four virological failures with DTG and one with PI/r with no emergent resistance mutations. There was no significant difference in severe adverse events or grade 3 or 4 adverse events or treatment modifying adverse events. Total cholesterol and other lipid fractions (except high-density lipoprotein cholesterol) improved significantly (P < 0.001) in the DTG group regardless of PI/r at baseline. Conclusion: Switching to a DTG regimen in virologically suppressed HIV type 1 patients with high cardiovascular disease risk was noninferior, and significantly improved lipid profiles.
