Brief Summary
This study is being done to learn more about an investigational medicine called PF-08653944. The goal is to understand how the body handles the medicine and to check its safety after a single dose. The study includes adults with normal liver function and adults who have mild, moderate, or severe liver problems. By comparing these groups, researchers want to understand whether liver function changes how the medicine behaves in the body. People who join the study will receive one injection of the study medicine. They will stay at the study clinic for a short time and return for follow-up visits so doctors can do blood tests, physical exams, and safety checks. This study is not expected to provide direct medical benefit to participants. The information collected will help researchers develop future treatments and understand how this medicine may be used safely in people with liver disease.
