Effect of an Investigational Compound on Tolerability of Extended Release Niacin (0524A-023)(COMPLETED)

A Worldwide, Multicenter, Double-Blind, Randomized, Parallel, Study to Evaluate the Efficacy of MK0524 to Improve Tolerability of Extended Release Niacin

This is a 12-week clinical trial in lipid clinic patients for whom niacin therapy is appropriate to evaluate the efficacy of MK0524 to improve the tolerability of extended-release niacin. There will be 6 scheduled clinic visits and 3 treatment arms.

• Non-diabetic patients with 2 or more risk factors for coronary heart disease and no ischemic cardiovascular disease must have LDL-C <160 mg/dL at V1
• Patient has TG <500 mg/dL (5.65 mmol/L) at V1
• A patients historic serum or plasma lipid values measured within 6 months from Visit 1 may be used to meet lipid inclusion criteria
• ALL OTHER PATIENTS DO NOT REQUIRE SPECIFIC LIPID ENTRY CRITERIA
