Brief summary
The study was conducted to determine if cenicriviroc mesylate (CVC) would decrease vascular inflammation as measured by 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) imaging of the aorta and carotid arteries.
Detailed description
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.
Interventions
Administered as one 150-mg tablet by mouth once a day with food.
Administered as two 150-mg tablets by mouth once a day with food.
Administered as one 150-mg matching placebo tablets by mouth once a day with food.
Administered as two 150-mg matching placebo tablets by mouth once a day with food.

Intervention model description
At study entry, participants were randomized 2:1 to oral CVC (Arm A) or oral placebo for CVC (Arm B) once a day. The study treatment was added to the participants' pre-existing antiretroviral treatment (ART) regimens.

|---|---|---|
| Change (Expressed as Ratio to Baseline) in 18-FDG-PET Target-to-background Ratio (TBR) of the Most Diseased Segment (MDS) of the Index (Most-inflamed) Vessel. | Measured at baseline and week 24 | Target-to-Background Ratio (TBR) measures the intensity of inflammation of a target arterial wall (aorta, left carotid, right carotid), relative to its respective blood background. Specifically, it is the ratio of the Standardized Uptake Value (SUV) of 18-FDG-PET in the target vessel to SUV in the blood background. A negative number for the change in TBR means a reduction in the target arterial wall inflammation over time. Index vessel is the vessel with the highest vessel TBR at baseline. The most diseased segment is the approximately 1-cm section of the vessel with the highest activity at baseline. The results are expressed as the ratio of TBR at week 24 to baseline. For the statistical analyses, results for the 6 and 9 missing values in Arm A and Arm B, respectively, were imputed using multiple imputation by regression. |

Outcome results
Change (Expressed as Ratio to Baseline) in 18-FDG-PET Target-to-background Ratio (TBR) of the Most Diseased Segment (MDS) of the Index (Most-inflamed) Vessel.
Target-to-Background Ratio (TBR) measures the intensity of inflammation of a target arterial wall (aorta, left carotid, right carotid), relative to its respective blood background. Specifically, it is the ratio of the Standardized Uptake Value (SUV) of 18-FDG-PET in the target vessel to SUV in the blood background. A negative number for the change in TBR means a reduction in the target arterial wall inflammation over time. Index vessel is the vessel with the highest vessel TBR at baseline. The most diseased segment is the approximately 1-cm section of the vessel with the highest activity at baseline. The results are expressed as the ratio of TBR at week 24 to baseline. For the statistical analyses, results for the 6 and 9 missing values in Arm A and Arm B, respectively, were imputed using multiple imputation by regression.
