Baclofen for Anxiety and Alcohol Use Disorder (AUD): an Open Label Study (BAC2)

February 14, 2025 updated by: Universitair Ziekenhuis Brussel

Investigating the Efficacy of Baclofen in Patients with Alcohol Use Disorder (AUD) and Comorbid Anxiety Symptoms

The goal of this clinical trial is to determine the efficacy of baclofen for the treatment of alcohol use disorder (AUD) in patients with or without comorbid anxiety symptoms. The main questions it aims to answer are:

  • Do we see more abstinent days after the study period in patients with high anxiety symptoms compared to low anxiety symptoms?
  • Do we observe additional differences between patients with high- and low anxiety symptoms in: any drinking at the end of treatment (yes/no), number of patients who respond to treatment, anxiety score reduction, autonomic responses, craving scores, drinking motives and side effects?

Participants already taking baclofen as part of routine clinical care for treatment of AUD will be asked to answer several questionnaires over a 6 week study period.

Study Overview

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

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.

Enrollment (Estimated)

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Meeting DSM-5 criteria for AUD
  • Able to understand and provide written consent
  • Already receiving baclofen or started with baclofen at start of hospitalization
  • Therapeutic desire towards alcohol abstinence

Exclusion Criteria:

  • Concurrent substance use disorder other than nicotine or cannabis
  • Clinically significant psychiatric illness that requires pharmacotherapy, unless stable and no changes in medication has been made in the last 30 days

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Baclofen
SIngle arm study, investigating baclofen as standard care uptitrated to maximal tolerated dosage upon clinical judgment and not part of the trial. The active intervention involves questionnaires.
Other: Questionnaires
Questionnaires include: the Alcohol Use Disorder Identification Test (AUDIT), Composite Autonomic Symptom Score (COMPASS-31), Depression Anxiety Stress Scale (DASS-21), Drug Desire Questionnaire (DDQ), Drinking Motives Questionnaire short form (DMQ-SF), Mini International Neuropsychiatric Interview (MINI), PROMIS-alcohol, Timeline Follow Back (TLFB) and Visual Analog Scale for craving (VAS).

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
Number of days abstinent
Time Frame: Weekly during 6 week study period
Number of days abstinent during baclofen treatment between AUD patients with and without comorbid anxiety, as measured by the TLFB.
Weekly during 6 week study period

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
Any drinking
Time Frame: After 6 week study period
Any drinking (i.e. drinking yes or no at the end of treatment) between AUD patients with and without comorbid anxiety, as measured by the TLFB.
After 6 week study period
Treatment response
Time Frame: After 6 week study period
Number of individuals who respond to baclofen treatment, defined as reducing their alcohol use by more than 30% over the 6 week study period, as measured by the TLFB.
After 6 week study period
Autonomic symptom responses
Time Frame: At start and after 6 week study period
Autonomic symptom responses measured by the COMPASS-31 assessing 6 domains of autonomic symptoms: orthostatic intolerance, vasomotor, secretomotor, gastro-intestinal, bladder and pupillomotor.
At start and after 6 week study period
Craving scores
Time Frame: Weekly for the VAS and bi-weekly for the DDQ during the 6 week study period
Craving scores measured by self-report VAS for craving and the DDQ.
Weekly for the VAS and bi-weekly for the DDQ during the 6 week study period
Anxiety score reduction
Time Frame: At start and after 6 week study period
