Registered outcomes4

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryChange From Baseline in Percent Atheroma Volume at Week 78Baseline and week 78
Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. The extent of atherosclerosis was expressed as percent atheroma volume (PAV) in a ≥ 40 mm segment of one targeted (imaged) coronary artery, calculated as the percentage of the total vessel volume occupied by atheroma.
SecondaryChange From Baseline in Total Atheroma Volume at Week 78Baseline and week 78
Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. Total atheroma volume (TAV) in a ≥ 40 mm segment of the targeted coronary artery was calculated as the average plaque area over the number of images that were evaluated by IVUS multiplied by the median vessel length to compensate for differences in segment length between participants.
SecondaryPercentage of Participants With Regression in Percent Atheroma VolumeBaseline and week 78
Intravascular ultrasound (IVUS) was used to visualize the extent of atherosclerotic plaques in the coronary artery lumen. The extent of atherosclerosis was expressed as percent atheroma volume (PAV) in a ≥ 40 mm segment of one targeted (imaged) coronary artery, calculated as the percentage of the total vessel volume occupied by atheroma. Regression in PAV was defined as any reduction from baseline in PAV.
