Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Log CAC Volume Score From Baseline to Week 52 for the Combined Dose Groups vs Placebo
Time Frame: Baseline (Week 1, Day 1) and Week 52
|
Coronary Artery Calcification (CAC) Volume Score is a calculation to quantify the calcification of coronary artery calcium without factoring in the calcium density as measured by the CAC Agatston Score. The CAC Score was log-transformed and the primary outcome measure was the change in Log CAC Volume Score from Baseline to Week 52 for the combined dose groups vs placebo. The primary analysis used an ANCOVA model with the change in log volume score (log 52-week volume score - log baseline volume score) as the dependent variable and with a fixed effect term for the combined randomized treatment groups and log CAC volume score at baseline as a covariate. The least squares means for the treatment groups was estimated and back transformed. A smaller change from baseline to follow up is a better outcome. |

Coronary Artery Calcification (CAC) Agatston Score is a semi-automated tool to calculate a score the reflects the extent of coronary artery calcification as detected by an unenhanced CT scan.
Scores range from 0 to >1000 Agatston units where higher scores indicate an increased amount of calcification and an increased risk for a major adverse cardiac event.
This secondary outcome measure was the change in Log CAC Agatston Score from Baseline to Week 52 for each dose group and the treated arms combined vs placebo.
The analysis used an ANCOVA model with the change in log score (log 52-week score - log baseline score) as the dependent variable and with a fixed effect term for each randomized treatment groups and log CAC score at baseline as a covariate.
The least squares means for each of the treatment groups separately and combined was estimated and back transformed.

Agatston score is a semi-automated tool to calculate a score that reflects the extent of coronary artery calcification as detected by an unenhanced CT scan.
Scores range from 0 to >1000 Agatston units where higher scores indicate an increased amount of calcification and an increased risk for a major adverse cardiac event.
Change in Agatston Score values from baseline to Week 52 were calculated as a percentage of change (progression or worsening of calcification).
The number of subjects with <15% progression were counted.
