This is a 105-week clinical study in patients with heterozygous familial hypercholesterolemia on intensive Low Density Lipoprotein-cholesterol (LDL-C) lowering therapy intended to assess the affects of MK0524A on carotid intima media thickening using ultrasound compared to patients taking placebo. There will be 12 scheduled clinic visits involving review of medical history, physical exam, vital signs, laboratory testing, ultrasound imaging, and electrocardiograms.

Condition Intervention Phase
Hypercholesterolemia, Familial Drug: Comparator: niacin (+) laropiprant (MK0524A) Drug: Comparator: placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Worldwide, Double-Blind, Randomized, Placebo-Controlled Study of MK0524A 2g Coadministered With Intensive LDL-C Lowering Therapy Compared to Intensive LDL-C Lowering Therapy Alone on Carotid Artery Intima Media Thickening (cIMT) in Patients With Heterozygous Familial Hypercholesterolemia (heFH)
