SECONDARY outcome

Timeframe: Screening and Week 16

Change in homeostatic model assessment for insulin resistance (HOMA-IR) from screening to end of study. Insulin resistance is a condition in which cells fail to respond to the normal actions of the hormone in the body. The HOMA-IR is calculated using a subject's fasting plasma insulin and glucose levels. The higher the score, the higher the level of insulin resistance.
