A Prospective, Randomized, Open Label Trial of Two Doses of Oral Betaine in Patients With Non-alcoholic Fatty Liver Disease (NAFLD) and Elevated Alanine Aminotransferase (ALT)

Betaine (trimethyglycine) is a food supplement that is approved for sale in the United States
without a prescription. In this study, betaine will be provided to patients as a powder that
can be mixed with aqueous solutions and consumed orally.

This is a prospective, unblinded, randomized study of oral betaine in diabetic and
non-diabetic patients who have a clinical diagnosis of NAFLD and an ALT≥ 50 IU/mL. A clinical
diagnosis of NAFLD is based on the presence of risk factors for NAFLD (such as overweight and
insulin resistance) and the exclusion of other causes of liver disease, such as alcohol or
viral hepatitis.

Two cohorts of patients will be studied: Cohort 1 (diabetic) will consist of patients with a
clinical diagnosis of non-insulin dependent type II diabetes mellitus; Cohort 2
(non-diabetics) will consist of patients without a clinical diagnosis of type 2 diabetes
mellitus. 24 patients will be enrolled in each cohort (total of 48 patients enrolled in the
study) with an anticipated drop out of 4 subjects per cohort.

Patients will be given dietary instructions and advice on exercise appropriate for the
management of NAFLD (NIDDK and liverfoundation.org handouts). Patients will be prescribed 4
grams of betaine/day (2 grams PO BID) for the first 4 weeks of the study. After 4 weeks,
patients in each cohort (NIDDM and non-diabetic) will be randomized (1:1) to continue
receiving betaine 4 grams per day or increase to 8 grams per day for an additional 8 weeks.
All patients will be seen in clinic on a monthly basis during treatment, and again 4 and 12
weeks after completion of betaine treatment. The total duration of the study is 24 weeks (12
weeks of betaine treatment and 12 weeks of follow-up).

The primary outcome is change in ALT during 12 weeks of betaine treatment (i.e., ALT at week
12 compared with ALT at baseline (entry). Secondary outcomes include safety, efficacy of
betaine in each cohort, and are changes in laboratory tests related to NAFLD.
