Primary outcomePrimary: Part 1: Number of Participants With Treatment Emergent Adverse Events (TEAEs) — 4; 1; 2; 1 Participants

Summary

The purpose of this clinical trial is to learn if the study medicine (called PF-07817883) is safe and how it goes in and out of the body in healthy people. PF-07817883 is for the potential treatment of COVID-19. Participants will take PF-07817883 by mouth up to 2 times a day. This study may also evaluate how much PF-07817883 gets into the body when taken as pill. We may study if people's diets can affect this study medicine. We may also examine how PF-07817883 is processed and removed by the human body. Finally, we may look into if PF-07817883 has potential to interact with midazolam.
