Treatment of Nonalcoholic Steatohepatitis With Metformin

Nonalcoholic Steatohepatitis (NASH) is associated with progressive liver disease, fibrosis, and cirrhosis. Although the cause of NASH is unknown, it is often associated with obesity, type 2 diabetes, and insulin resistance. At present, there are no approved treatments for NASH patients, but an experimental approach has focused on improving their insulin sensitivity. Metformin is one of the most commonly used medications for the treatment of diabetes. The purpose of this study is to determine whether the medical problems of NASH patients, specifically liver damage, improves when their insulin sensitivity is enhanced with metformin. The study will last 3 to 5 years and will enroll up to 30 patients. Participants will undergo a complete medical examination, a series of lab tests, and a liver biopsy. They will then start taking a single 500-mg tablet of metformin once a day for 2 weeks, then the same dosage twice a day for 2 more weeks, if they tolerate the first dosage. The dosage will increase to 1,000 mg twice a day for the remaining 44 weeks of the study. After 1 year, participants will undergo a repeat medical examination and liver biopsy.

1 Interventions

Name: Metformin

Description: After complete medical evaluation and liver biopsy, patients who qualified for therapy were started on metformin in an initial dose of 500 mg once daily. After 2 weeks, the dose was increased to 500 mg twice daily and after 4 weeks to the full dose of 1000 mg twice daily. Subsequent dose reductions were carried out based on tolerance, with particular attention to gastrointestinal upset and abdominal bloating. Patients were seen in the out-patient clinic, had a brief medical history and examination and routine blood tests at 2 and 4 weeks after enrolment and every 4 weeks thereafter. The oral and intravenous glucose tolerance tests were repeated after 40 and 44 weeks respectively and liver biopsy and imaging tests at 48 weeks. Metformin was discontinued after 48 weeks in patients without diabetes on the pre-treatment evaluation.
Type: Drug


Primary Outcomes

Description: Patients under went liver biopsy, metabolic profiling and imaging studies before and at the end 48 weeks of metformin (2000 mg/day) therapy. The primary endpoint is a three point improvement in the histological NASH activity index with a decrease in at least two of the component scores and no worsening of fibrosis or increase in Mallory bodies.

Measure: Change in the Histological NASH Activity Index at 48 Weeks Compared With Baseline (Number of Participants in Each Change Category)

Time: from baseline to 48 Weeks

Secondary Outcomes

Description: Alanine transaminase <42 U/L is considered normal

Measure: Change in Serum Alanine Aminotransferase (ALT) Levels From Baseline (Number of Participants in Each Change Category)

Time: from baseline to 48 weeks

Description: HOMA-IR is calculated from Fasting Glucose and Fasting Insulin

Measure: Change in Insulin Sensitivity (Glucose Tolerance, Homeostatic Model Assessment of Insulin Resistence (HOMA-IR)) From Baseline

Time: from baseline to 48 weeks

Purpose: Treatment
