About this study
Official title: Naltrexone and Psychosocial Treatments for the Treatment of Cocaine Dependence Complicated by Alcohol Dependence
The purpose of this study is to see whether naltrexone is safe and useful in preventing alcohol relapse, as well as in decreasing craving for alcohol in people with a diagnosis of alcohol and cocaine dependence. Naltrexone is approved by the Food and Drug Administration (FDA) for the treatment of alcohol dependence. However, the medication was not approved as yet at the dosage we will use in this study. The dosage we will use for the study (150 mg), is greater than the recommended dosage from the Physician's Desk Reference (50mg). Unlike other medicines (like Antabuse) useful in the treatment of alcohol dependence, naltrexone will not make you sick if you drink alcohol. Rather, people who are taking this medication have reported that it helps decrease the pleasure associated with drinking for them. This study is being conducted because the medication (Naltrexone) has not been well studied in people with both alcohol and cocaine dependence, so it is still investigational.
We believe that if we can reduce alcohol consumption through naltrexone and psychotherapy, this may lead to reduced cocaine use. We are also conducting this study to test two different types of psychotherapy as a method for reducing cocaine and alcohol use. One type of psychotherapy is designed to help people learn to cope with situations that put them at high risk for relapse to cocaine and/or alcohol use. The other type of psychotherapy we will use focuses on strengthening motivation to recover from cocaine and/or alcohol use, and on developing techniques to handle possible barriers to recovery. We seek to enroll 300 patients in the study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to see whether naltrexone is safe and useful in preventing alcohol relapse, as well as in decreasing craving for alcohol in people with a diagnosis of alcohol and cocaine dependence. Naltrexone is approved by the Food and Drug Administration (FDA) for the treatment of alcohol dependence. However, the medication was not approved as yet at the dosage we will use in this study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Naltrexone in people with Cocaine Dependence and Alcoholism, run by University of Pennsylvania 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 6 inclusion and 10 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 28 Feb 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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.
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 28 Feb 2018.
