A Multicenter, Randomized, Double-blind, Placebo-controlled, 3-parallel-group Comparison Trial to Investigate the Effect of Nalmefene on Alcohol Consumption Reduction in Patients With Alcohol Dependence (Phase 3 Trial)

September 3, 2019 updated by: Otsuka Pharmaceutical Co., Ltd.
The efficacy, safety, and dose-response of nalmefene hydrochloride at 10 mg and 20 mg in patients with alcohol dependence will be evaluated in a multicenter, randomized, double-blind, placebo-controlled, 3-parallel-group comparative trial. The superiority of nalmefene hydrochloride at 20 mg to placebo will be verified in terms of reduction of alcohol consumption.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
