A Study to Learn How Different Amounts of the Study Medicine Called PF-07976016 Are Tolerated and Act in The Body in Healthy Adults
Study Details
Study Description
Brief Summary
The purpose of this clinical trial is to learn if the study medicine (called PF-07976016) is safe and how it goes in and out of the body in healthy people. The study may also explore if PF-07976016 has the potential to interact with another medicine called midazolam. In addition, the study may explore how PF-07976016 goes into the body of people who have obesity.
