Evaluation of the Efficacy of Sodium Oxybate in the Long-term Maintenance of Abstinence in Alcoholic Patients — GATE2  

Alcohol Dependence Clinical Trial

Official title:
Multinational, Multicentre, Double-blind, Placebo-controlled Evaluation of the Efficacy of GHB in the Long-term Maintenance of Abstinence in Alcoholic Patients After the Initial Weaning Phase, Stratified by Lesch's Taxonomy (GATE 2)

Clinical Trial Summary

Additional pharmacotherapies in the treatment of alcohol dependence are needed. Sodium oxybate showed efficacy in the maintenance of abstinence in alcohol-dependent patients in several small randomized trials of short duration. The aim of the present phase III/IV study is to confirm in a randomized-controlled study the efficacy and safety of oral sodium oxybate in the maintenance of abstinence.

Clinical Trial Description

Alcohol dependence (AD) is the most severe form of alcohol use disorder. It occurs in 2.6% of people aged 15+ years worldwide and can result in a reduction of life-expectancy by several years as compared with the general population. Currently, disulfiram, acamprosate and naltrexone are the main medicinal products registered for the maintenance of abstinence in AD patients. Although effective on the group level, effects sizes are limited, and many AD patients fail to respond to these medications. Therefore, additional pharmacological treatments are needed. Sodium oxybate 50mg/kg/day showed evidence of efficacy compared to placebo and naltrexone in the maintenance of abstinence in AD patients in a series of open label and blinded randomized controlled trials (RCTs). However, studies were generally small and did not investigate the sustainability of the Sodium oxybate effect post-treatment. The present phase III/IV RCT (GATE 2) aimed to confirm the efficacy and safety of oral Sodium oxybate in the maintenance of abstinence. Secondary aims included the assessment of sustained SMO effects during the 6-month medication free period immediately following the 6-month treatment period and monitoring the risk of Sodium oxybate dependence. ;
