Study Summary

The purpose of this study is to learn how different forms of the study medicine called PF-08049820 are absorbed and eliminated in healthy adults. The study will assess whether the study medicine is absorbed differently when taken with or without food. It will also assess absorption when the study medicine is taken with another medicine called rabeprazole. Rabeprazole is an FDA approved medicine that reduces stomach acid. The study has two parts. In Part A, participants will take three forms of study medicine, one after the other. They will take each form either with or without food for a total of five doses. Each dose will be separated by a few days. Participants will stay in the clinic for about two weeks. They will receive a telephone follow-up call about a month after the last dose. In Part B, participants will take three forms of study medicine. They will take each one with or without food, and with or without another medicine called rabeprazole. This means they will take a total of six doses of study medicine. Each dose will be separated by a few days. Participants will stay at the clinic for about three weeks, and about a month after their last dose. They will get a follow-up phone call. Part B may or may not be conducted depending on the results from Part A. The study is seeking participants who: 1. Are males or females, 2. Are at least 18 years of age, 3. Have a body mass index (BMI) 16 to 32 kilograms per meter squared (kg/m2). Have a total body weight of more than 50 kilograms (kg) (110 pounds).

Primary Outcome

Part A: Evaluate the relative bioavailability of different formulations of PF-08049820. Optional Part B: Estimate the effect of rabeprazole on the PK of different formulations of PF-08049820.
