- No healthy volunteers
- Adult
Who may be able to join
- Each subject must:

- Exhibit current, clinically significant physical disease or abnormality on the basis of medical history, physical examination, or routine laboratory evaluation, including AST or ALT levels greater than 3 times normal or bilirubin levels greater than 110% of normal. Individuals with common medical conditions (e.g., asthma, diabetes mellitus, thyroid disease) that are adequately controlled and who have a relationship with a primary-care practitioner will not be excluded;

- Have a current DSM-IV diagnosis of alcohol dependence that is clinically severe defined by a) a history of seizures, delirium, or hallucinations during alcohol withdrawal, b) a Clinical Institute Withdrawal Assessment scale (Sullivan et al., 1989) score of > 8, c) report drinking to avoid withdrawal symptoms, or d) have had prior treatment of withdrawal.
- Have used opioids or concomitant therapy with any psychotropic drug in the past month, except that subjects who are on a stable dose of a Selective Serotonin Reuptake Inhibitor for at least two months for the indications of Major Depressive Disorder, Premenstrual Syndrome (PMS), or Premenstrual Dysphoric Disorder (PMDD) will not be excluded; SSRIs are allowed due to their safety profile relative to other classes of antidepressants.

About this study
In this study, 140 heavy drinking young adults (aged 18-25) will be provided with brief counseling and either naltrexone, a medication that is FDA-approved for the treatment of alcohol dependence, or placebo over the course of 8 weeks. A novel strategy will be used for administering low-dose naltrexone, in which daily dosing will be combined with targeted dosing in anticipation of high-risk situations. The main hypotheses are that daily + targeted naltrexone will result in greater reductions in frequency of heavy and any drinking compared with daily + targeted placebo.
Read the detailed description
NIAAA has designated underage drinking as a priority research area. Of note, the highest prevalence of problem alcohol use is among young adults ages 18-25. Heavy drinking that occurs during this period can have important immediate and lifelong adverse consequences. Behavioral interventions, notably BASICS (Brief Alcohol Screening and Intervention for College Students), have been developed to help young adults reduce their drinking. Although these interventions are effective, including with college students mandated to treatment and others with minimal motivation to stop drinking, the effect sizes are modest, suggesting that new approaches are needed to enhance these interventions. A promising strategy yet to be tested in young adults is the use of the opiate antagonist naltrexone. In other research, naltrexone has been shown to reduce the amount of alcohol consumed, even in the absence of strong internal motivation to change, and to reduce the frequency of any and heavy drinking in problem drinkers seeking treatment. Thus we propose to conduct an 8 week double-blind placebo-controlled trial to test the combined efficacy of BASICS + naltrexone in 132 young adults aged 18-25 who drink heavily. A novel strategy will be used for administering low-dose naltrexone, in which daily dosing will be combined with targeted dosing in anticipation of high-risk situations. The main hypotheses are that daily + targeted naltrexone will result in greater reductions in frequency of heavy and any drinking compared with daily + targeted placebo. In order to enhance the sensitivity with which we are able to assess naltrexone's effects on drinking, daily ratings will be obtained during treatment. These will permit us to examine alternative measures of alcohol involvement (e.g., reports of subjective intoxication, estimated blood alcohol levels) in addition to the traditional measures based on number of drinks consumed. These data will also be used to examine potential mediators (e.g., craving, subjective effects of alcohol) of treatment response in order to better understand the effects of naltrexone. The durability of treatment effects will be examined at 3, 6 and 12 months after randomization. Demonstration of the efficacy of naltrexone in this population will provide the essential information needed for its adoption by college counseling centers and other health care settings committed to reducing the risk of heavy drinking in young adults.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BASICS counselingBehavioural
Also called brief counseling, brief intervention
Brief Alcohol Screening and Intervention for College Students (BASICS) is a form of counseling that was developed originally for use with undergraduates. It combines three main elements: motivational enhancement strategies, skills for moderating consumption, and provision of individualized feedback.
naltrexoneDrug
Also called ReVia, Depade
Daily + targeted (i.e., taken as needed in anticipation of a high-risk situation) naltrexone, 25mg each for a total possible dose of 50mg (the FDA-approved dose for alcohol dependence) in a given day for a period of 8 weeks.
placebo naltrexoneDrug
Daily + targeted (i.e., taken as needed in anticipation of a high-risk situation) placebo for a period of 8 weeks.

What is being measured
The primary outcome is the main question the study is designed to answer.
Frequency of Heavy Episodic Drinking
Self-reported drinking was primarily obtained through diary data, with the Timeline Follow-Back Interview (TLFB) used to replace missing data at baseline and at each biweekly visit over the 8-weeks.The eight weeks follow-up measure is summarized across all biweekly visits. Frequency of heavy episodic drinking is measured as 5 or more drinks in a day for males, and 4 or more drinks in a day for females. A standard drink was equivalent to 0.6 gm of absolute alcohol (e.g., 12-oz beer, 5-oz wine, or 1.5-oz, 80-proof liquor). Baseline measures captured the prior 4 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing BASICS counseling and naltrexone in people with Alcohol Consumption and Alcoholic Intoxication, run by Yale University 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 9 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 30 Mar 2020. 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 11 Aug 2014). 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?
Frequency of Heavy Episodic Drinking (time frame: Baseline). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00568958, which also lists 1 linked publication.
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 30 Mar 2020.
