Who can take part
You may be able to join if
- Able and willing to understand and sign a written informed consent form (ICF) that must be obtained prior to the initiation of study procedures
- Age >=18 through <=75 years at enrolment
- History or presence of 2 or more of the 5 components of metabolic syndrome per American Heart Association definition
- History or presence of known or suspected MASH
You likely can't join if
- ALT or AST >=5 × upper limit of normal (ULN)
- Phosphatidylethanol (PEth) >=80 nanogram per milliliter (ng/mL) at Screening
- Evidence of infection with any of the following: a. Human immunodeficiency virus; b. Hepatitis B virus (detectable HBsAg at Screening); c. Hepatitis C virus (HCV)
- Chronic liver disease from any other cause including, but not limited to, alcoholic liver disease; evidence of portal hypertension; viral hepatitis, or any history or evidence of cirrhosis; or decompensated liver disease such as clinical ascites, bleeding gastroesophageal varices, hepatorenal syndrome, or hepatic encephalopathy prior to Screening or Day 1.
- Current or history of excessive alcohol intake for >=3 months within the 12-month period prior to Screening
- Total bilirubin (BILI) >=1.3 milligram per deciliter (mg/dL). Individuals with documented Gilbert's syndrome may be enrolled if they experienced an isolated increase in total BILI of >=1.3 mg/dL and direct BILI is <=20% of total BILI; otherwise, the individual will be excluded.
