Safety and Efficacy of Nalmefene in Patients With Alcohol Dependence

Phase 3
Completed
Conditions
Alcohol Dependence
Interventions
Drug: Placebo
Registration Number
NCT00811941
Lead Sponsor
H. Lundbeck A/S
Brief Summary

The purpose of the study is long-term safety, tolerability and efficacy of nalmefene in patients with alcohol dependence.

Detailed Description

Alcohol dependence is a maladaptive pattern of alcohol use, leading to clinically significant impairment or distress, as manifested by at least three of a number of criteria such as tolerance, withdrawal symptoms, frequent use of alcohol in larger amounts or over longer periods than was intended, and others. Excessive intake of alcohol reduces the life span by a decade, and alcohol drinking is strongly related to mortality from liver cirrhosis, chronic pancreatitis, certain cancers, hypertension, accidents and violence. This study is planned to evaluate the long-term safety and tolerability as well as to evaluate the efficacy of as needed use of 18.06 mg nalmefene in patients with alcohol dependence.

Primary Outcome Measures
NameTimeMethod
Number of Patients With Adverse Events (AEs)Serious Adverse Events: 52 weeks and a safety follow-up (visit/telephone call) scheduled for 4 weeks after completion of the study or after withdrawal from the study. Other Adverse Events: 52 weeks.

Overview of AEs

Percentage of Patients Who Withdrew Due to Intolerance to TreatmentBaseline to Week 52
Change From Baseline in the Monthly Number of Heavy Drinking Days (HDDs)Baseline and Month 6

Number of HDDs over a month (28 days), where one HDD was defined as a day with alcohol consumption ≥60 grams (g) for men and ≥40 g for women.

Change From Baseline in the Monthly Total Alcohol Consumption (TAC)Baseline and Month 6

TAC was defined as mean daily alcohol consumption in g/day over a month (28 days).

Secondary Outcome Measures
NameTimeMethod
Drinking Risk Level (RSDRL) ResponseMonth 13

RSDRL response was defined as a downward shift from baseline in Drinking Risk Level (DRL); for patients at very high risk at Baseline: a shift to medium risk or below, and for patients at high or medium risk at Baseline: a shift to low risk or below.

Change From Baseline in Clinical Status Using CGI-SBaseline and Week 52

The Clinical Global Impression - Severity of Illness (CGI-S) provides the clinician's impression of the patient's current state of mental illness. The clinician uses his or her clinical experience of this patient population to rate the severity of the patient's current mental illness on a 7-point scale ranging from 1 (Normal - not at all ill) to 7 (among the most extremely ill patients).

Change in Clinical Status Using the CGI-IWeek 52

The Clinical Global Impression - Global Improvement (CGI-I) provides the clinician's impression of the patient's improvement (or worsening). The clinician assesses the patient's condition relative to a baseline on a 7- point scale ranging from 1 (very much improved) to 7 (very much worse).
