Multiple Dose Study for a New Medication to Potentially Treat Liver Diseases

Who May Qualify: - Considered eligible based on the medical history, physical examination, and the results of vital signs, electrocardiogram and clinical laboratory tests performed during the screening visit, as judged by the investigator. - Male or female (of non-childbearing potential) aged 18-64 years (both inclusive) at the time of signing the willing to sign a consent form. - Body mass index (BMI) 25.0 to 39.9 kilogram per square meter (kg/m\^2) (both inclusive) at screening. - Liver fat content measured by magnetic resonance imaging - estimated proton density fat fraction (MRI-PDFF) greater than or equal to (\>=) 10 percent and liver stiffness greater than 8 kilopascal (kPa) as measured by FibroScan® (vibration-controlled transient elastography \[VCTE™\]). Additional inclusion criteria for participants in the open-label liver biopsy cohort apply: - Alanine aminotransferase (ALT) in men greater than (\>) 30 units per liter (U/L), women \> 19 U/L - Liverstiffness, measured by FibroScan® (VCTE) \> 8 kPa and less than (\<) 12 kPa - willing to sign a consent form obtained at screening for a liver biopsy to be performed at baseline and post-treatment. Note: Participants with confirmed metabolic dysfunction-associated steatohepatitis (MASH), based on a prior liver biopsy, can be included in the open-label cohort. Who Should NOT Join This Trial: - Any disorder, which in the investigator's opinion might jeopardise participant's safety or compliance with the protocol. - Any laboratory safety parameter, at screening, outside the extended laboratory ranges, and considered clinically significant per the principal investigator (see laboratory provided reference ranges for specific values). Of note, re-screening or re-sampling is NOT allowed if the individual has failed one of the exclusion criteria related to the following laboratory parameters: - ALT \>= 3 × upper limit of normal (ULN) - Aspartate aminotransferase (AST) \>= 3 × ULN - Bilirubin \> 1.5 × ULN ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
