Healthy Volunteers
Conditions
Brief summary
The purpose of this study is to determine whether concentrations of the study drug (evacetrapib) in the blood stream is the same or is different when the person is also taking gemfibrozil (a drug used to lower lipid levels). Each participant will receive gemfibrozil alone, evacetrapib alone, and both drugs in combination. There is no washout period between doses. The safety of both of the study drugs given together will be evaluated. Information about any side effects that may have occurred will also be collected. This study will last approximately 36 days.
