Overview
The purpose of this study is to learn how a certain amount of \[14C\] PF-07320948 is taken up into the bloodstream and removed from the body.
This study is seeking participants who are:
- Male between 18 to 64 years of age
- Deemed to be healthy
This is a 2 Part, 4 Period study where Part 1 has Periods 1 and 2 and Part 2, which is optional, has Periods 3 and 4.
Part 1
- Period 1: The purpose is to see how much of the study medicine PF-07328948 gets into and leaves the body.
- Period 2: The goal is to compare how much PF-07328948 is available in the body when taken by mouth versus by injection into the blood.
Part 2 (Optional)
- Period 3 (optional): If needed, the purpose is to see how PF-07328948 acts after taking it daily until the body reaches a steady level.
- In Period 4 (optional), the goal is to check again how much PF-07328948 is absorbed and leaves the body after daily dosing.
During study clinic stays and study visits, the study team will collect urine and blood samples and perform safety reviews. If only Part 1 is conducted, total time in the study (screening (start) through follow-up (end)) will be about 14 weeks. If both Part 1 and Part 2 are conducted, total time in the study will be about 22 weeks.
