Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 18 to 60 years
- All sexes
- No healthy volunteers
- Adult
Who may be able to join
- Age 18-60.
- Meets DSM-IV criteria for current opiate dependence disorder of at least six months duration, supported by a positive urine for opiates and a positive naloxone challenge test if the diagnosis is unclear. If participating as an outpatient only, recent opiate dependence must be confirmed by clinical history and/or communication with former treatment provider.
- Seeking treatment for heroin dependence.
- Able to give informed consent.
Who cannot join
- Methadone maintenance treatment or regular use of illicit methadone (> 30 mg per week).
- Maintenance on, or regular use of buprenorphine or other long-acting narcotic agonists.
- Pregnancy, lactation, or failure in a sexually active woman to use adequate contraceptive methods.
- Active medical illness which might make participation hazardous, such as untreated hypertension, hepatitis with SGOT or SGPT > 3 times normal, unstable diabetes.
- Active psychiatric disorder which might interfere with participation or make participation hazardous, including DSM-IV schizophrenia, bipolar disorder with mania or psychosis, and depressive disorder with suicide risk or 1 or more suicide attempts within the past year.
- Physiologically dependent on alcohol or sedative-hypnotics with impending withdrawal. Other substance use diagnoses are not exclusionary. Multiple substance use is common in this population, and such an exclusion would rule out a large proportion of the population and limit the generalizability of the study.

- History of allergic reaction to buprenorphine, naltrexone, naloxone, clonidine, or clonazepam.
- Chronic organic mental disorder (e.g. AIDS dementia).
- History of accidental drug overdose in the last 3 years as defined as an episode of opioid-induced unconsciousness or incapacitation, whether or not medical treatment was sought or received.

About this study
Official title: Behavioral Naltrexone Therapy (BNT) for Promoting Adherence to Oral Naltrexone (BNT-oral) vs Extended Release Injectable Depot Naltrexone (Depot-BNT); a Randomized Trial
In pilot study now proposed, we plan to randomly assign 60 opioid dependent patients to the new model, Depot-BNT, or to BNT plus oral naltrexone for a 6-month trial. This will provide initial clinical experience with the new Depot-BNT treatment model, while providing a rigorous test of whether Depot-BNT produces superior treatment outcome, compared to our best behavioral platform for oral naltrexone (BNT).
The following aims will be addressed:
Read more
Specific Aim #1: To test whether Depot-BNT increases retention in treatment and improves drug use outcome (urine-confirmed abstinent weeks) compared to our established model of BNT with oral naltrexone (BNT-Oral), and to explore whether Depot-BNT (vs BNT-Oral) improves key secondary outcomes including dysphoria, HIV risk behavior, and social functioning.
Specific Aim #2: To explore predictors of outcome on Depot-BNT, and mechanisms of attrition, in order to optimize Depot-BNT prior to further testing.
Read the detailed description
The clinical trial now proposed will provide an initial test of the feasibility and efficacy of the newly adapted version of Behavioral Naltrexone Therapy for Depot Naltrexone (Depot-BNT). Treatment-seeking opiate-dependent patients will be admitted for inpatient detoxification and induction onto oral naltrexone. Those who are successfully inducted will be randomly assigned for a six month trial to one of two conditions: 1) Behavioral Naltrexone Therapy for Depot Naltrexone (Depot-BNT) (N = 30), with the first dose of depot naltrexone administered prior to discharge from hospital with monthly doses thereafter; or 2) Behavioral Naltrexone Therapy as previously developed for promoting compliance with daily oral naltrexone (BNT-Oral) (N = 30). All patients in both groups will be asked to attend twice weekly outpatient therapy sessions over a six month course. This design will provide a test of whether Depot-BNT produces superior treatment retention and drug use outcome in comparison to our established behavioral platform for oral naltrexone, while providing experience upon which to base revisions of Depot-BNT prior to embarking upon further Stage 2 testing. Treatment will take place at the same sites as for our prior studies: (1) the General Clinical Research Unit (GCRU) of New York State Psychiatric Institute (NYSPI) and (2) the Substance Treatment and Research Service (STARS) of the Division on Substance Abuse at NYSPI.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
depot naltrexoneDrug
Also called Vivitrol
On the afternoon of Day 7, patients assigned to Depot-BNT receive an intramuscular injection of Vivitrol (380 mg) in one buttock. The patient spends the night of Day 7 in the hospital and is discharged on the morning of Day 8. Each injection contains 192 mg of naltrexone. The double dose (384 mg) is what was found to produce optimal blockade and outcome in preliminary work. During the subsequent 6-month course of outpatient treatment, patients are dosed with two injections (384 mg total) of depot naltrexone at monthly intervals (weeks 4, 8, 12, 16, 20).
Oral NaltrexoneDrug
Also called Revia
For patients assigned to BNT-Oral, administration is clinic-based for at least the first two weeks, and doses are 50mg, 100mg, or 150mg, depending on whether one, two or three days will elapse before the next visit (typically 100 mg on Monday and Wednesday and 150 mg on Friday). The ultimate goal with BNT-Oral is for patients to take naltrexone (50 mg per day) on their own at home under supervision of their significant other/monitor.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing depot naltrexone and Oral Naltrexone in people with Opiate Dependence and Heroin Dependence, run by New York State Psychiatric Institute 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 4 inclusion and 11 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 25 Aug 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. 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?
Yes. Results are posted in the registry (first posted 25 Aug 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?
Treatment Retention (time frame: over the course of 24 weeks or length of study participation). 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 NCT00577408, 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 25 Aug 2017; AzTrials last refreshed its copy on 6 Nov 2026.
