Summary

This is a multicenter, randomized, double-blind, placebo-controlled study in participants with primary hypercholesterolemia or mixed dyslipidemia, and elevated low density lipoprotein-cholesterol (LDL-C) to assess the efficacy and safety of extended release (ER) niacin/laropiprant \[ERN/LRPT (MK-0524A)\] when added to the following ongoing lipid-modifying therapy (LMT): simvastatin, atorvastatin, rosuvastatin monotherapy, ezetimibe/simvastatin fixed dose combination (FDC), or any statin co-administered with ezetimibe. The study is based on the hypothesis that ERN/LRPT 2 g daily will be superior to placebo at lowering LDL-C at Week 12 of treatment.

Conditions

• Primary Hypercholesterolemia
• Mixed Dyslipidemia

Interventions

Type	Name	Description
DRUG	Extended-release niacin/laropiprant (ERN/LRPT)	1 oral 1 g tablet of ERN/LRPT to be taken with food in the evening or at bedtime for the first 4 weeks of treatment; then 2 oral 1g tablets of ERN/LRPT to be taken together in the evening or at bedtime with food for the next 8 weeks. Each 1g tablet contains 1g ERN and 20 mg LRPT
DRUG	Placebo	1 oral 1 g tablet of placebo to be taken with food in the evening or at bedtime for the first 4 weeks of treatment; then 2 oral 1g tablets of placebo to be taken together in the evening or at bedtime with food for the next 8 weeks.
