Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

The following subjects were recruited:

* males and females;
* of any ethnic group;

* with a responsible relative or caregiver;
* having issued the informed consent.

Exclusion Criteria
