A CCTA Imaging Trial to Evaluate the Effect of Obicetrapib/Ezetimibe on Coronary Plaque (REMBRANDT)

April 6, 2026 updated by: NewAmsterdam Pharma

A Placebo-controlled, Double-blind, Randomized, Phase 3 Study to Evaluate the Effect of Obicetrapib/Ezetimibe Fixed Dose Combination Daily on Coronary Plaque Characteristics in Participants With Atherosclerotic Cardiovascular Disease on Coronary CT Angiography (REMBRANDT Trial)

This placebo-controlled, double-blind, randomized, Phase 3 study is being conducted in adult participants with high-risk atherosclerotic cardiovascular disease (ASCVD) who are not adequately controlled by their maximally tolerated lipid-modifying therapy, to assess the impact of the obicetrapib 10 mg + ezetimibe 10 mg FDC daily on coronary plaque and inflammation characteristics, evaluated using cardiovascular computed tomography angiography (CCTA).
