About this trial

This is an interventional treatment trial for Nonalcoholic Steatohepatitis focused on measuring Nonalcoholic Steatohepatitis, NASH, L-Alanine

Eligibility Criteria

18 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Males and females, age between 18 and 75
  • Histological diagnosis of steatohepatitis with or without fibrosis made within one year of entry
  • Transaminase levels (ALT or AST) more than 1.5 times the upper normal limit on at least two occasions with one assessment in three months or more prior to treatment of this study
  • Previous and current alcohol consumption less than 20g per day by patient-provided information.
  • Written informed consent specific for this protocol available prior to entry.
  • Patients with diabetes and on stable medical management for six months prior to entry and an anticipated stable program throughout the study will be eligible. Medications that may be used include insulin, biguanides and sulfonylureas.
  • Patients with congestive heart failure, hypertension and arrhythmia controlled by medications and without cardiac episodes during the past 6 months will be eligible.

Exclusion Criteria:

  • Any causes for liver disease other than nonalcoholic steatohepatitis that are confirmed by patient history, laboratory data, or histological data

  • Any previous experimental treatment of NASH within the past 3 months such as betaine, thiazolidinediones, α-tocopherol, or UDCA
  • Pre-existing diseases/situations that could interfere with the results or the completion of this trial.
  • Uncontrolled diabetes mellitus meeting following criteria in previous 3 months

    1. Fasting blood sugar >200 mg/dl

  • Chronic pulmonary disease such as COPD requiring corticosteroid therapy in previous 3 months
  • Active autoimmune or immunologically mediated diseases including systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel diseases in previous 12 months
  • Previous (in three years) or present malignant disease except for non-melanoma skin cancer
  • Untreated hyperthyroidism and hypothyroidism
  • Substance abuse of oral, I.V., or inhaled drugs.
  • If patients with history of substance abuse are considered as participants in this trial, patients must have abstained from using the abused substance for at least one year.
  • Patients receiving methadone within the past 6 months are also excluded.
  • Any other conditions that would make the patients unsuitable for enrollment in the opinion of the investigator in terms of interference in completing the trial and/or results of trial.
  • Pregnant women
  • Unwillingness of patients and /or partner to use contraceptive during treatment and for 3 months after discontinuation of treatment.
