Nalmefene, Baclofen and Impulsivity in Subjects With Alcohol Use Disorder and Healthy Control Subjects

October 28, 2020 updated by: Prof. Daniele Zullino

Effects of Nalmefene and Baclofen on Impulsivity in Subjects With Alcohol Use Disorder and Healthy Control Subjects: A Randomized, Placebo-controlled Study

Impulsivity is a central feature of addiction. Nalmefen is an authorized treatment for alcohol addiction. Baclofen has empathically been advocated to have some efficacy in this indication. The aim of the present study is to test the effect of Nalmefene and Baclofen on impulsivity.

Primary study objective: To examine the effect of Nalmefene and Baclofen on impulsivity (as measured by the Stop Signal Task) in subjects with alcohol use disorder and healthy control subjects.

Main secondary study objectives: To examine the effect of Nalmefene and Baclofen on risk taking (as measured by the Balloon Analogue Risk Task) and on the preference for small immediate rewards over large delayed rewards (as measured by the Delay Discounting Task). To compare subjects with alcohol use disorder and healthy control subjects on these tasks.

Primary study outcome: Stop-signal reaction time in the Stop-Signal Task Main secondary study outcomes: Equivalence point in the Delay-Discounting Task and Average number of pumps delivered in the Balloon Analogue Risk Task

Study Design: Randomized, placebo control, cross-over, single-dose

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

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.
Outcome Measure
Measure Description
Time Frame
Change in "Stop-signal reaction time" in the Stop-Signal Task
Time Frame: 0 and 2 hours post-dose
Before-drug/after-drug difference of the stop-signal reaction time in the Stop Signal Task at Visit 2, Visit 3 and Visit 4.
0 and 2 hours post-dose

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.
Outcome Measure
Measure Description
Time Frame
Change in "Equivalence point" in the Delay-Discounting Task
Time Frame: 0 and 2 hours post-dose
Before-drug/after-drug difference of the Equivalence point" in the Delay-Discounting Task at Visit 2, Visit 3 and Visit 4.
0 and 2 hours post-dose
Change in "Average number of pumps" delivered in the Balloon Analogue Risk Task
Time Frame: 0 and 2 hours post-dose
Before-drug/after-drug difference of the "Average number of pumps" delivered in the Balloon Analogue Risk Task at Visit 2, Visit 3 and Visit 4.
0 and 2 hours post-dose
