Official title
A PHASE 1, OPEN-LABEL, FIXED SEQUENCE, 2-PERIOD STUDY IN HEALTHY ADULT PARTICIPANTS TO ASSESS THE MASS BALANCE, ABSOLUTE BIOAVAILABILITY, FRACTION ABSORBED, AND PHARMACOKINETICS OF [14C]PF-07799544 USING A 14C-MICROTRACER APPROACH
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
For this study, the study medicine has been specially prepared to contain radiolabeled carbon \[14C\]. \[14C\] is a naturally occurring radioactive form of the element carbon. Adding a low dose of radiation to the study medicine does not change how the medicine works but helps to see how the medicine appears in the blood, urine, and stool after it is given. This type of study is called a radiolabeled study. The purpose of this radiolabeled study is to learn how a certain amount of \[14C\] PF-07799544 is taken up into the bloodstream and removed from the body. The study is seeking participants who are: Male Ages 18 to 55 years of age confirmed to be healthy based on medical and physical tests. Weigh more than 50 kilograms (kg) and have a body mass index of 17.5 to 32 kg per meter squared. The study consists of two parts. In part one, all participants will receive one full dose of \[14C\]PF-07799544 by mouth. Part two will begin at least 14 days after the dose in part one. In part two, participants will receive one full dose of PF-07799544 by mouth and one small dose of \[14C\] PF-07799544 by intravenous (IV) infusion. IV infusion will be directly injected into the veins. To understand how the medicine is processed in the body, samples of blood, urine, feces, and vomit (if any) will be collected after each dose is given. This will help understand: How much PF-07799544 is taken up into the bloodstream when taken by mouth compared to the dose given by IV How the body removes it from the blood steam. Participants will take part in the study for about 7 weeks, including evaluation at the start and follow-up period.
