About this trial
The overall objective of the trial is to evaluate the effect of the triple therapy consisting of bempedoic acid (BA), ezetimibe (EZE), and high-intensity atorvastatin or rosuvastatin on changes in coronary plaque burden and plaque morphology in patients with coronary atherosclerosis without significant obstructive coronary artery disease and without prior history of an ischemic vascular event.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age ≥18 years
Having provided informed consent for participation in this trial
Lipid-lowering treatment-naïve
Unequivocal atherosclerosis in ≥5 American Heart Association (AHA) coronary segments (corresponding to a risk equivalent of obstructive coronary artery disease) and coronary artery disease - reporting and data system (CAD-RADS) category 1, 2, or 3
Disqualifiers
Known or suspected heterozygous or homozygous familial hypercholesterolaemia or familial combined hyperlipidaemia
Known contraindication for BA, EZE, atorvastatin, and/or rosuvastatin. A participant with a contraindication for atorvastatin, can be assigned to triple therapy with rosuvastatin, and vice versa.
Not expected to remain on a stable dose of high intensity triple therapy for the duration of the trial.
History of myocardial infarction, stroke, or peripheral artery disease (PAD), and/or coronary revascularisation (percutaneous coronary intervention [PCI] or coronary artery bypass grafting [CABG])

Trial outcomes
Primary outcomes
Annualised change in percentage plaque burden (Δ%PB)
This endpoint will evaluate the effectiveness of the triple therapy in reducing plaque burden (PB).
Secondary outcomes
Key Secondary: Annualised change in normalised non-calcified plaque volume (PV)
This endpoint will assess the efficacy of the triple therapy by evaluating changes in plaque composition and morphology.
Percentage of participants with regression in normalised total plaque volume (TPV), normalised non-calcified PV, and normalised low attenuation PV at EoT (i.e., ΔPV and Δnon-calcified PV, and Δlow-attenuation PV)
This endpoint will evaluate the potential impact of the triple therapy on total plaque volume (TPV) regression, non-calcified PV regression, and low attenuation PV regression.
Change in the absolute Agatston coronary artery calcium (CAC) score
This endpoint will evaluate the potential impact of the triple therapy on coronary calcification. CAC measures the total area and density of calcified plaque in the heart's arteries, ranging from 0 to over 400. A score of 0 indicates no plaque, while higher scores indicate increased risk of cardiovascular events, with \>400 indicating extensive disease.
Annualised ΔTotal Plaque Volume (TPV)
This endpoint will evaluate the effectiveness of the triple therapy in reducing TPV.
