A PHASE 1, OPEN-LABEL, 2-PERIOD, FIXED SEQUENCE STUDY TO INVESTIGATE THE ABSORPTION, DISTRIBUTION, METABOLISM AND EXCRETION OF [14C]PF-07081532 AND TO ASSESS THE ABSOLUTE BIOAVAILABILITY AND FRACTION ABSORBED OF PF-07081532 IN HEALTHY MALE PARTICIPANTS USING A [14C]-MICROTRACER APPROACH
A PHASE 1, OPEN-LABEL, 2-PERIOD, FIXED SEQUENCE STUDY TO INVESTIGATE THE ABSORPTION, DISTRIBUTION, METABOLISM AND EXCRETION OF [14C]PF-07081532 AND TO ASSESS THE ABSOLUTE BIOAVAILABILITY AND FRACTION ABSORBED OF PF-07081532 IN HEALTHY MALE PARTICIPANTS USING A [14C]-MICROTRACER APPROACH
The purpose of this clinical trial is to learn about how much PF-07081532 will be taken up and processed by healthy male participants. The study consists of two parts, called study periods. In Period 1, participants will take one dose of PF-07081532 by mouth. In Period 2, participants will take one dose by mouth and one dose as an injection through a vein at the study clinic.
In Period 1, participants will stay at the clinic site for up to 21 days. In Period 2, they will stay at the clinic site for 7 days. During their stays, participants will have their blood, urine, and feces collected by the study doctors several times. We will measure the level of PF-07081532 in participants' blood, urine, and feces samples. This will help us know how much the study medicine is getting taken in by the body. At the end of the study, participants will be contacted by phone to check in. Participants will be involved in this study for about 12 weeks.
Key Eligibility criteria for this study include, but are not limited to the following:
Inclusion criteria:
Healthy Male participants must be 18 to 60 years of age, inclusive.
Overtly healthy as determined by medical evaluation including medical history, physical examination, blood pressure and pulse rate measurement, standard 12-lead ECG, and laboratory tests.

Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures
Exclusion criteria:
History of irregular bowel movements (eg, irritable bowel syndrome, frequent episodes of diarrhea, or constipation defined by less than 1 bowel movement on average per 2 days) or lactose intolerance
Any condition possibly affecting drug absorption (eg, gastrectomy, cholecystectomy).
Previous administration with an investigational product (drug or vaccine) within 90 days (or as determined by the local requirement) preceding the first dose of study intervention used in this study.
Total 14C radioactivity measured in plasma exceeding 11 mBq/mL.
