Each clinical study has its own guidelines for who may participate, called eligibility criteria. These factors can include your age, sex, overall health, type and stage of disease, and personal treatment history. However, only the research study staff can determine if you qualify to enroll in the study.

Group 4 only: screening seated systolic blood pressure ≥140 mm Hg or diastolic blood pressure ≥90 mm Hg
Group 1, 2 \& 3 only: Hepatic carcinoma or hepatorenal syndrome or limited predicted life expectancy (defined as <1 year in Groups 2 \& 3 and <6 months for Group 1 only).
Group 1, 2 \& 3 only: a diagnosis of hepatic dysfunction secondary to any acute ongoing hepatocellular process that is documented by medical history, physical exam, liver biopsy, hepatic ultrasound, CT scan, or MRI.
Group 1, 2 \& 3 only: history of gastrointestinal hemorrhage due to esophageal varices or peptic ulcers less than 4 weeks prior to screening.

Groups 1, 2 \& 3 only: ALT or AST >5x upper limit of normal on clinical laboratory tests at screening.

Study overview

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.
