A Study to Evaluate the Effects of Cenicriviroc Mesylate on Arterial Inflammation in People Living With HIV

This was a double-blind, placebo-controlled phase II clinical trial comparing the intervention of CVC versus placebo for a duration of 24 weeks on arterial inflammation evaluated by FDG-PET/CT imaging.

A total of 110 participants were randomized 2:1 to the CVC arm (Arm A) or placebo for CVC arm (Arm B). Stratification by statin use at randomization ensured even distribution of statin use between the treatment groups.

Analyses were based on the efficacy population: all enrolled participants who completed at least 22 weeks of study treatment and remained on the same ART drug class throughout the study without use of prohibited medications.

Analysis of the primary outcome utilized multiple imputation by regression to impute missing data.

Key Inclusion Criteria:
