Safety and Benefit of MBX-8025 With and Without Commonly Used Statins in Moderately Overweight Patients With High Cholesterol

Total participation for each patient is approximately 16-17 weeks, which may include up to a 2 week screening period, 5 week run-in period, 8 week treatment period, and 2 week follow-up. During the run-in period patients taking statins, statin combination or Zetia will undergo a 'washout'. All patients will be instructed to follow a weight-maintenance diet (i.e., their same diet prior to entering the study). They will be asked to defer initiating any weight loss diets or meaningful changes in their activity level until after they have completed the study. Once randomized into the double blind study, patients will visit the clinic every two weeks thereafter until the end of the study. At the end of the 8-week treatment phase, the double-blind study medication will be discontinued. Patients will attend a follow up visit two weeks after their final dose for safety evaluation.
