A Study to Learn How the Body Processes the Study Medicine PF-07328948 in People With and Without Reduced Liver Function (NCT07269301)

A PHASE 1, OPEN-LABEL, SINGLE-DOSE, PARALLEL-COHORT STUDY TO EVALUATE THE PHARMACOKINETICS, SAFETY, AND TOLERABILITY OF PF-07328948 IN ADULTS WITH AND WITHOUT VARYING DEGREES OF HEPATIC IMPAIRMENT

๐ŸŸข Recruiting Phase1 ๐Ÿ’Š Investigational Drug / Biologic Sponsor: Pfizer

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The purpose of this study is to understand the effects of decreased liver function on the study medicine (PF-07328948). People with decreased liver function may process the study medicine differently from healthy people. Study is seeking participants who: * Are between 18 and 75 years of age. * Have a BMI (body mass index) of 17.5 to 40 kg/m2, inclusive, and a total body weight of more than or equal to 45 kilograms or 99 pounds. Participants will take the study medicine as a tablet once at the study clinic and then will stay onsite for about 6 days. During this time, the study team will check for the participant's treatment experience and take some blood samples to test the level of PF-07328948. This will help understand if certain level of decreased liver function could affect the study medicine being processed in the body.
