Patient description: A 22-year-old Caucasian man came to the Clinic with a history of tremors since a year ago. The tremor was first in his right hand while holding something. Later the tremor became continuous and extended to both hands and legs and even at rest. The Kayser-Fleischer' ring was detected in the ophthalmologic exam. The physical exam revealed jaundice, hepatosplenomegaly and hypotonia of the upper limbs. He had a constant smile on his face, however, he has aggressive behavior according to his parents' explanation. His laboratory study was significant for a low serum caeruloplasmin (0.05 g/l), and a raised 24 hour urine copper excretion (120 μg/24 h). Wilson disease was confirmed by high liver copper concentration (305 μg/g dry weight of liver).

Clinical trial eligibility criteria: eligible ages (years): 18.0-75.0,  Non-alcoholic Fatty Liver Disease Clinical evidence of NASH defined as a. histological evidence of NASH (no more than 3 years prior to screening) OR b. clinical imaging results suggestive of NASH (no more than 3 years prior to screening) OR within the screening phase, imaging procedures performed as per local standard) i. evidence of hepatic steatosis >5% measured by the MRI-PDFF) or assessed as moderate to severe steatosis (raised echogenicity of the liver parenchyma) by ultrasound AND ii. evidence of liver fibrosis defined as mean stiffness > 3.64 kPa as measured by the MRE protocol or mean stiffness > 7.2 kPa as measured by ultrasound based transient elastography (Fibroscan®) Increased ALT defined as a. ALT >1.5 ULN at screening and ALT >1.25 ULN in a local lab within 1 week to 3 months prior screening OR b. Historic ALT > 1.25 ULN more than 3 months prior to screening and two consecutive ALT > 1.5xULN must be confirmed at least 1 week apart within the screening period Age ≥ 18 and ≤75 years at screening BMI ≥25kg/m2 and <45kg/m2 at screening Stable body weight defined as less than 5% change in body weight in the 3 months prior to screening while being treated with the standard of care and not treated with anti-obesity medication at screening Treatment with Antidiabetic concomitant medication including any insulin regimen needs to be stable for 3 months, and treatment with vitamin E needs to be stable for 6 months prior to informed consent and expected to be stable throughout the trial. All other concomitant medication has to be stable for at least 4 weeks prior screening. Concomitant medications taken to treat acute conditions (e.g. headache, sinusitis) for a short period (< 7 days) are permissible, if not otherwise prohibited For female patients: Women of childbearing potential* can be randomized after a negative pregnancy test and under adequate contraception with two methods, of which at least one is highly effective, during the trial.* A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods hysterectomy, bilateral salpingectomy and bilateral oophorectomy. Tubal ligation is NOT a method of permanent sterilisation. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause Signed and dated written informed consent in accordance with GCP and local legislation prior to admission to the trial  Current or history of significant alcohol consumption (defined as intake of >210g/week in males and >140g/week in females on average over a consecutive period of more than 3 months) or inability to reliably quantify alcohol consumption based on investigator judgement Prior participation in an interventional NASH trial 6 months before baseline or 5 times halflife of the investigational drug, whichever is longer Prior or planned bariatric surgery during study conduct, except gastric-band surgery more than 2 years prior to screening (including adjustments) with a stable body weight within the last 12 months Use of drugs historically associated with liver injury, hepatic steatosis or steatohepatitis in the 4 weeks prior to screening History of liver cirrhosis (fibrosis stage 4), or hepatic decompensation (e.g. ascites, hepatic encephalopathy, variceal bleeding, etc.) or history of other forms of chronic liver disease (for example Hepatitis B, Hepatitis C, autoimmune liver disease, primary biliary sclerosis, primary sclerosing cholangitis, Wilsons disease, hemochromatosis, A1At deficiency, history of liver transplantation) Active known chronic or relevant acute infections, such as HIV (Human Immunodeficiency Virus), \viral hepatitis, or tuberculosis. QuantiFERON® TB test and HBs Ag test will be performed during screening. Patients with a positive test result may participate in the study if further work up (according to local practice/guidelines) establishes conclusively that the patient has no evidence of active infection Solid liver lesions other than haemangiomas. - Suspicion or diagnosis or history of hepatocellular carcinoma (HCC) eGFR <60ml/min/1.73m2 at screening (CKD-EPI formula) ALT >5.0 ULN at screening
