A Novel Pharmacotherapy for Alcoholism and Alcohol Liver Disease
Completed · Phase 2
Conditions studied: Alcoholism,, Alcoholic Liver Disease
In brief
It is proposed to test metadoxine (MTDX) that it is hypothesized to be significantly beneficial for the treatment of alcoholism and ALD. Metadoxine is currently approved in Europe for acute and chronic alcohol intoxication but has never been tested in the US. Furthermore, MTDX is used in Europe to treat ALD. Preliminary evidence shows that MTDX reduces alcohol consumption in AD individuals. If the role of MTDX in reducing alcohol consumption and improve liver function is confirmed by a rigorous study design, then MTDX might represent a truly innovative pharmacotherapy for AD, given the potential to be used for AD individuals with ALD. However until this proposal, MTDX has never been investigated as a treatment for AD able to reduce both alcohol consumption and improve alcohol-related liver damage via a double-blind placebo-controlled study. This project therefore proposes to conduct a 12-week (followed by a 3-month follow-up), double-blind, placebo-controlled, between-subject randomized clinical trial with MTDX (500mg t.i.d.) in AD individuals.

You may qualify if…
- age ≥18;
- females must be post-menopausal for ≥1 year, surgically sterile, or practicing a birth control before entry and throughout the study; have a negative urine pregnancy test at screening and before randomization;
- current DSM-IV diagnosis of alcohol use disorder (or if relevant at study start-DSM-V) with current (i.e. past 90 days prior to screening) "at-risk" drinking defined as an average overall consumption of ≥28 drinks/week for men and ≥21 drinks/week for women;
- desire abstinence;
- evidence of alcoholic liver disease (ALD) based on a thorough history, physical examination, and laboratory tests (i.e. the De Ritis ratio of AST:ALT ratio \~2:1), which is characteristic of ALD.
You may not qualify if…
