About

The study is a placebo-controlled, double-blind, randomized, phase 3 study in participants with heterozygous familial hypercholesterolemia (HeFH) and/or atherosclerotic cardiovascular disease (ASCVD) or multiple ASCVD risk factors to evaluate the efficacy, safety and tolerability of obicetrapib 10mg and ezetimibe 10mg fixed dose combination as an adjunct to diet and maximally tolerated lipid-lowering therapy.

Full description

This study will be a placebo-controlled, double-blind, randomized, phase 3 study in participants with heterozygous familial hypercholesterolemia (HeFH) and/or atherosclerotic cardiovascular disease (ASCVD) or multiple ASCVD risk factors to evaluate the efficacy, safety, and tolerability of obicetrapib as an adjunct to diet and maximally tolerated lipid-lowering therapy. The screening period for this study will take up to 14 days. Afterwards patients will be randomized 1:1:1:1 to Obicetrapib 10 mg and ezetimibe 10 mg fixed dose combination, obicetrapib 10 mg, ezetimibe 10 mg or placebo for a 84 day treatment period. After the treatment period, patients will have an end of study follow-up visit.
