About this study

Official title: Placebo Controlled Pilot Study of Dutasteride for the Reduction of Alcohol Use in Male Drinkers

The purpose of this study is to evaluate whether dutasteride is safe and effective for reducing alcohol use in male drinkers who want to stop or reduce their drinking. The investigators hypothesize that at a dosage of 1mg/day, dutasteride will be well tolerated and that, compared to placebo treatment, dutasteride will result in a greater reduction in the amount of alcohol consumed per week. The study sample size is of a pilot scale and is designed to provide additional support for the study hypothesis and provide an estimate of likely effect sizes in order to design a more definitive study.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DutasterideDrug

    Also called Avodart

    dutasteride 4 mg loading dose followed by 1 mg daily for 8-week treatment period

  • PlaceboDrug

    Also called Lactose

    placebo capsules in same number as active drug, daily for 8-week treatment period

What is being measured

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

  1. Change Number of Standard Drinks Per Week.

    Change in Average Standard Drinks (14 gr ethanol) per week: last 2 weeks of treatment (wk 7-8) minus baseline average drinking average from baseline 90 day drinking history

    Measured: Baseline (average weekly drinking for 90 day period prior to screening) vs. End Point (average weekly drinking weeks 7 and 8 of treatment)

Secondary outcomes (1)
  1. Change in Standard Drinks Per Week - Moderation by Genetic Variation

    Moderation of primary outcome measure [change in standard drinks per week from baseline to end point (average weeks 7 and 8 of treatment)] by genetic variation rs12529 in neuroactive steroid biosynthetic enzyme gene AKR1C (AKR1C3*2 C-allele associated with alcohol use disorder)

    Measured: Baseline (average weekly drinking for 90 day period prior to screening) vs. End Point (average weekly drinking weeks 7 and 8 of treatment)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dutasteride in people with Alcoholism and Alcohol Abuse, run by UConn Health 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 5 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 20 Mar 2017. 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 10 Feb 2017). 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?

Change Number of Standard Drinks Per Week. (time frame: Baseline (average weekly drinking for 90 day period prior to screening) vs. End Point (average weekly drinking weeks 7 and 8 of treatment)). 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 20 Mar 2017.
