About this study

Official title: A Double-Blind, Randomized, Placebo-Controlled Trial of Acamprosate in Alcohol-Dependent Individuals With Comorbid Bipolar Disorder

To conduct a double-blind, randomized, placebo-controlled outpatient clinical trial of acamprosate in individuals with alcohol dependence and bipolar disorder who are also receiving mood stabilizing medication. The study will assess the safety and efficacy of acamprosate in alcohol-dependent bipolar patients as measured by its effects on alcohol use and mood symptoms relative to placebo.

The primary hypothesis to be tested is whether individuals with comorbid bipolar disorder and alcohol dependence who receive acamprosate plus mood stabilizer will have greater improvement in alcohol-related outcomes than those who receive mood stabilizer alone. A secondary hypothesis that will be explored is that alcohol-dependent bipolar individuals treated with acamprosate will have greater mood stability as compared to those treated with mood stabilizers alone.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time to First Drink (Days)

    Number of days after randomization until consumption of first alcoholic beverage per self-report.

    Measured: 8 weeks

Secondary outcomes (8)
  1. Percent Days Abstinent

    Percentage of days in trial with no alcohol consumption

    Measured: 8 weeks

  2. Percent Heavy Drinking Days

    Percentage of drinking days that are heavy drinking days (5 or more standard drinks/day for males, 4 or more standard drinks/day for females)

    Measured: 8 weeks

  3. Percent Carbohydrate-deficient Transferrin

    Measured level of validated serum alcohol biomarker

    Measured: 8 weeks

  4. Gamma-glutamyltransferase

    Measured levels of validated serum alcohol biomarker

    Measured: 8 weeks

  5. Obsessive Compulsive Drinking Scale Score

    Higher scores indicate worse outcome; minimum score = 0, maximum score = 40

    Measured: 8 weeks

  6. Montgomery Asberg Depression Rating Scale Score

    MADRS scores at study endpoint. Higher scores indicate a worse outcome. Minimum score = 0, maximum score = 60.

    Measured: 8 weeks

  7. Young Mania Rating Scale Score

    YMRS scores at study endpoint. Higher scores indicate a worse outcome. Minimum score = 0, maximum score = 60.

    Measured: 8 weeks

  8. Clinical Global Impression Scale Score

    Higher values indicate worse outcomes; minimum value = 1, maximum value = 7

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Acamprosate in people with Alcohol Dependence and Bipolar Disorder, run by Medical University of South Carolina at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time to First Drink (Days) (time frame: 8 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Dec 2018.
