August 12, 2024 updated by: Organon and Co

A Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate Efficacy and Safety of Adding Ezetimibe 30 mg to An Ongoing Regimen of Ezetimibe 10 mg in Patients Homozygous Sitosterolemia

This is a 6-month study with patients who have the rare disease, sitosterolemia which may result in heart-related diseases. These patients have unusually high absorption of non-cholesterol sterols, resulting in heart-related diseases.
