Pharmacotherapy for Alcohol Dependence in Convicted Drinking Drivers

April 1, 2014 updated by: Bernard Le Foll, Centre for Addiction and Mental Health

A Multi-site Study to Disseminate and Evaluate Pharmacotherapy for Alcohol Dependence in Convicted Drinking Drivers

This pilot study will explore the ways to link Ontario's remedial system for convicted drinking drivers to medical intervention, assess the receptiveness of the Back on Track client population to effective medical interventions, and assess the feasibility of a full-scale trial of pharmacotherapy for convicted drinking drivers.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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.

Detailed Description

Many individuals with Alcohol Dependence do not receive treatment, despite effective treatments being available. A significant healthcare challenge is to find ways to bring people who have alcohol dependence into treatment programs. Drinking drivers are a group that has been shown to have high rates of alcohol dependence. In Ontario, all convicted drinking drivers who want to obtain a drivers license must complete Ontario's remedial program for convicted drinking drivers called Back on Track (BOT). In this program, those with more serious alcohol-related problems are assigned to a group treatment program. While it is likely that many of the individual in this group are experiencing alcohol dependence, currently there is no formal linkage to any medical services for these problems. In this study, the investigators will provide those in the BOT treatment group with information about a 24-week study assessing the effectiveness of naltrexone vs. placebo. This study will also assess the feasibility and level of interest among this population to obtain treatment for alcohol dependence.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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 to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders 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.
Outcome Measure
Measure Description
Time Frame
Participation rate
Time Frame: 2 years
We will determine what percentage of subjects will participate in the preliminary medical screening and what percentage of subjects with a diagnosis of alcohol dependence will participate in the trial.
2 years

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
Effect of naltrexone on drinking patterns and drinking related measures
Time Frame: At baseline and six-month follow-up
Clinical trial data of naltrexone vs. placebo will assess the effectiveness of the study intervention on alcohol related outcomes. Outcomes will include percent days abstinent, time to first heavy drinking day and alcohol craving. BOT program data for all participants will also be assessed including measures of drinking behaviour and measures of other drug use and consequences resulting from substance use. Ministry of Transportation data will be used to determine the long term effect on relevant outcomes such as collisions and charges associated with alcohol use.
At baseline and six-month follow-up
