Design outcomes

Primary

MeasureTime frame
Main Objective: To evaluate the effect of alirocumab on coronary atherosclerotic burden in terms of the change in percent atheroma volume (PAV) by means of atherosclerotic plaque quantification and virtual histology of the coronary tree based on the analysis of coronary computed tomography (CCTA) on asymptomatic FH patients receiving optimized and stable treatment with maximum tolerated doses of statins in combination or not with other lipid-lowering drugs.;Secondary Objective: - To evaluate the effect of alirocumab on the change of the normalized atheroma total volume (ATV) - To determine the percentage of patients that showed plaque regression - To evaluate the effect of alirocumab on the architecture and composition of the coronary wall - To evaluate the prevalence of basal aortic valve calcification and progression of calcification along the study - To evaluate the changes on lipid profile and Lp(a) levels along the study - To evaluate the security profile of alirocumab on daily practice - To evaluate the incidence and types of cardiovascular events during alirocumab treatment;Primary end point(s): Change in percent of atheroma volume (PAV) of the coronary tree between baseline (before the initiation of alirocumab) and 18 months after the beginning of alirocumab, based on angio CT images, analyzed with QAngio TC software;Timepoint(s) of evaluation of this end point: Baselline and 18 months after the beginning of treatment

Secondary

MeasureTime frame
Secondary end point(s): - Change on normalized VTA, based on ACT images at baseline and at 18 months after the beginning of alirocumab - Percentage of patients presenting atherosclerotic plaque regression 18 months after the beginning of alirocumab, based on percentage of patients showing PAV reduction or any VTA reduction from baseline - Changes in composition and architecture of atherosclerotic plaque, based on volume and percentage of fibrotic plaque, fibrofatty plaque, necrotic plaque and calcified plaque, form baseline to 18 months - Percentage of patients with aortic valve calcification and changes on calcium score, based on cuantitative measure of calcium in the aortic valve using Agatson method, based on coronary CT images without contrast administration, form baseline to 18 months - Change on cLDL and Lp(a) levels from baseline to 18 months after the beginning of alirocumab treatment - Safety profile of alirocumab, based on the development of adverse events in patients form baseline to final visit, including anomalous laboratory values, anomalies on examination or clinical AE - Incidence and type of cardiovascular events which have taken place during alirocumab treatmen, including death for ischemic cardiopathy, myocardial infarct, stroke, hospitalization for unstable angina or unplanned revascularization;Timepoint(s) of evaluation of this end point: Baseline, 3, 12 and 18 months
