Study Summary

The purpose of this study is to evaluate the relative bioavailability (rBA) of the Form 2 film-coated tablet of PF-07799933 intended for use in future studies compared to the current Form 1 tablet of PF-07799933 used in Phase 1 studies. Additionally this study will also evaluate the effect of a high-fat meal on the plasma pharmacokinetics (PK), i.e, the rBA compared to overnight fasting, of PF-07799933 and PF-07799544 following concurrent single-dose oral administration of Form 2 film-coated tablet formulation of PF-07799933 with PF-07799544. Finally, this study will also assess the impact of a proton pump inhibitor (a type of acid reducing agent) on PF-07799933 PK of the Form 2 film-coated tablet formulation. These data will be used to inform administration of PF-07799933 and PF-07799544 with food and acid reducing agents in future clinical trials.
