a study to evaluate the effects of cenicriviroc mesylate on arterial inflammation in people living with hiv

Conditions: HIV-1-infection

Summary: the study is being conducted to determine if cenicriviroc mesylate (cvc) will decrease vascular inflammation as measured by 18f-fluorodeoxyglucose (fdg)-positron emission tomography (pet)/computed tomography (ct) imaging of the aorta.

this is 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.
