Niacin/Laropiprant Tablet for South and Southeast Asians With Low High-Density Lipoprotein Cholesterol (LDL-C) at Risk for Cardiovascular Disease (MK-0524A-108)
April 27, 2015 updated by: Merck Sharp & Dohme LLC
A 16-Week, Randomized, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Extended Release Niacin/Laropiprant in South and Southeast Asians Not on a Lipid Modulating Agent, With Decreased High-Density Lipoprotein Cholesterol and Low- Density Lipoprotein Cholesterol at or Below NCEP ATP III Goal
The study will evaluate the use of extended release niacin/laropiprant (ERN/LRPT) combination tablets in a primary prevention population currently not taking or eligible for lipid-modifying therapy (LMT); the population will comprise participants with low to moderate risk for coronary heart disease (CHD), low high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) at or below goal level, and normal or mildly elevated triglyceride (TG) levels.
