| E.3 | Principal inclusion criteria |

Trial-related activities are any procedures that are carried out as part of the trial, including activities to determine suitability for the trial, except for protocol described pre-screening activities which require a separate informed consent. 2. Male or female, aged 18-75 years (both inclusive) (for Japan: male or female aged 20-75 years (both inclusive) at the time of signing informed consent.
 3. Histologic evidence of NASH based on central pathologist evaluation of a liver biopsy obtained up to 21 weeks before screening.
 4. A histological NAS > = 4 with a score of 1 or more in each sub-component of the score based on central pathologist evaluation.
 5. NASH fibrosis stage 1, 2 or 3 according to the NASH CRN fibrosis staging system based on central pathologist evaluation.
 
 |  | 
| E.4 | Principal exclusion criteria | 
| 1. Known or suspected abuse of alcohol (> 20 g/day for women or > 30 g/day for men), alcohol dependence* or narcotics. (* = assessed by the Alcohol Use Disorders Identification Test (AUDIT questionnaire)). 2. Diagnosis of type 1 diabetes according to medical records.
 3. HbA1c > 10% at screening.
 4. History or presence of pancreatitis (acute or chronic).
 5. Calcitonin ≥ 50 ng/L at screening.
 6. Family or personal history of multiple endocrine neoplasia type 2 or medullary thyroid carcinoma. Family is defined as a first degree relative.
 7. Body Mass Index (BMI) ≤ 25.0 kg/sqm at the screening visit (visit 1).
 8. Female who is pregnant, breast-feeding or intends to become pregnant or is of childbearing potential and not using an adequate contraceptive method (adequate contraceptive measures as required by local regulation or practice).
