Summary

This early-stage study tests a new experimental drug, PF-08103402, for the first time in people. It includes healthy adults and adults with mild-to-moderate asthma to check safety, how the drug moves through the body, and whether food affects its absorption. Participants take the drug by mouth as a liquid or tablet, with some groups receiving it daily for up to 14 days. The study also looks at how the drug interacts with another medicine and how it is broken down and eliminated.
