Primary Outcome Measures :
- Continuous abstinence rate in each group (baclofen or placebo) during 20 weeks of treatment, from Day 29 to Day 168. [ Time Frame: Day 168 ]
Secondary Outcome Measures :
- Continuous abstinence rate from the first intake of study treatment (Day 1) to the end of the maintenance dose period (Day 168), i.e. 24 weeks [ Time Frame: Day 168 ]
- Continuous abstinence rate from the first intake of study treatment (Day 1) to the end of 4-week post treatment follow up period (Day 210), i.e. 30 weeks [ Time Frame: Day 210 ]
- Continuous abstinence rate during 20 weeks of treatment (Day 29 to Day 168), according to the severity of alcohol dependence [ Time Frame: Day 168 ]
- Continuous abstinence rate during 20 weeks of treatment (Day 29 to Day 168), according to the level of drinking before withdrawal (Time Line Follow Back calendar/ World Health Organization criteria for risk of consumption) [ Time Frame: Day 168 ]
- Drinking characteristics for patients having a relapse between Day 1 and Day 210 [ Time Frame: Day 210 ]Time to relapse (Day 1 to first drinking day) Time to relapse to first high risk drinking day (>60g for a male, > 40g for a female) Percentage of drinking days from Day 1 to Day 210 Mean number of standard drinks per drinking day and classification according to World Health Organization criteria for the risk of consumption Percentage of high risk drinking days during the maintenance period at the target dosage (Day 50 to Day 168) compared to the percentage of high risk drinking days during the preceding 4 weeks of the withdrawal Percentage of drinking days during the maintenance period at the target dosage (Day 50 to Day 168) compared to the percentage of drinking days during the preceding 4 weeks of the withdrawal
- Change in craving, addiction and Quality of Life scales [ Time Frame: Day 210 ]Clinical Global Impression (CGI), Alcohol dependence Quality of Life (AlQoL9), Obsessive Compulsive Drinking Scale (OCDS), Hospital Anxiety and Depression Scale (HAD), Visual Analogue Scale (VAS) craving scores and liver biomarkers
- Recording of safety data [ Time Frame: Day 210 ]Adverse events, vital signs, biological parameters, ECG and urinary pregnancy test
