About

The purpose of this study is to evaluate the effect of SCH 497079 on metabolic parameters and to determine the influence of race/ethnic origin on therapeutic response.

Full description

This study includes two parts, each part includes three consecutive 28-day treatment periods. Part 1 (to be conducted in the United States): each participant will receive the following treatments for 28 days in each of three treatment periods in an order determined by a random code: SCH 497079, or matching placebo, or metformin. Part 2 (to be conducted in India): this part of the study will be conducted after completion of Part 1 and an analysis indicates a clinically significant decrease in blood glucose in participants with type 2 diabetes mellitus (T2DM) compared to placebo. The same procedures conducted in Part 1 will be conducted in Part 2.
