About this trial
The purpose of this study is to evaluate whether colchicine can reduce coronary artery inflammation in people living with HIV and high cardiovascular risk. Participants will be randomized 1:1 to receive either colchicine or placebo for 96 weeks in a double-blind, multicenter clinical trial. Neither participants nor researchers will know which treatment is assigned during the study. The primary endpoint is the change in coronary artery inflammation measured by coronary computed tomography angiography (CCTA) after 96 weeks.

Treatments tested in this trial
Colchicine 0.5 mg
DrugColchicine 0.5 mg administered orally once daily for 96 weeks as an anti-inflammatory treatment to reduce coronary artery inflammation in people living with HIV and high cardiovascular risk.
Placebo
DrugMatching placebo administered orally once daily for 96 weeks.
Treatment groups
Trial outcomes
Primary outcomes
Changes in coronary artery inflammation
Percent change from baseline of the mean Fat Attenuation Index (FAI) score for the three main coronary arteries (right coronary artery \[RCA\], left anterior descending artery \[LAD\], and left circumflex artery \[LCX\]). The mean FAI score will be calculated as the average of analyzable FAI scores with valid baseline and post-baseline measurements across the three coronary arteries.
Secondary outcomes
Changes in coronary plaque volume
Change from baseline in total coronary plaque volume assessed by coronary computed tomography angiography (CCTA) at Week 96.
Changes in coronary plaque burden
Change from baseline in coronary plaque burden assessed by coronary computed tomography angiography (CCTA) at Week 96.
Change in non-calcified plaque volume
Change from baseline in non-calcified coronary plaque volume assessed by coronary computed tomography angiography (CCTA) at Week 96.
Change in mixed plaque volume
Change from baseline in mixed coronary plaque volume assessed by coronary computed tomography angiography (CCTA) at Week 96.
Other outcomes
Sex-related differences in inflammatory patterns and treatment response
Difference in the percentage change of Fat Attenuation Index (FAI) between males and females in both treatment groups assessed by coronary computed tomography angiography (CCTA) in week 96.
CYP2D6 genotype-related differences in treatment response
Difference in FAI percentage change according to CYP2D6 metabolizer classification in participants receiving colchicine.
Major adverse cardiovascular events (MACE)
Difference in major adverse cardiovascular events (MACE) between colchicine and placebo groups assessed clinically in week 96.
Cardiovascular risk score
Change from baseline in the CaRi-Heart risk score, including mean absolute change and mean percentage change.
