Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to evaluate the efficacy, safety, and tolerability of enlicitide decanoate in adult participants with heterozygous familial hypercholesterolemia. The primary hypothesis is that enlicitide decanoate is superior to placebo on mean percent change from baseline in low-density lipoprotein cholesterol (LDL-C) at Week 24.
