The purpose of this pilot study is to learn what study factors are important in designing a large, full-scale study of the effects of TRIA-662 on serum triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) levels. In this study, patients will first enter a Single-blind, dietary-controlled baseline period and receive 1000 mg placebo or active drug three times daily with meals (i.e., breakfast, lunch, and dinner) for 6 - 8 weeks. If the qualify to continue, they will then receive up to 2000 mg of active or placebo drug for an additional 14 weeks. Active drug will be given to 48 patients and placebo drug will be given to 16 patients. However, neither the patients not the clinic staff will know which patients are on active or placebo drug until the end of the study.

The objective of this study is to compare the absorption of a niacin metabolite (1-methylnicotinamide, 1-MNA) from TRIA-662 (1-methylnicotinamide chloride)relative to the production of 1-MNA from Niaspan. The 1-MNA information obtained from this study will be used to adjust the top dose of a planned TRIA-622 efficacy study.

The Purpose of this study is to determine the safety and tolerability of 1-MNA, a drug that is intended to be used in the treatment of elevated levels of blood fats. This study will determine the way that 1-MNA is handled by the body, and will also determine its effect on commonly measured blood fat parameters.
