Summary

This study will look at a study drug called PF-08642534 in people with obesity (have too much body weight) to see: if participants can take different amounts (doses) of the study drug in a safe way and how adults with obesity tolerate it, and how the body handles the study drug (for example, how the study drug is absorbed and removed from the body). People who want to join the study will first go through a screening period of up to 4 weeks. Doctors will check if each person meets the study conditions, including age, body weight, and general health.
