About this study

Official title: Prevention of Relapse to Opioid Addiction Using Depot Naltrexone

The aim of this project is to conduct a multi-site effectiveness study to determine whether the addition of a monthly injection of depot naltrexone to treatment as usual (TAU) will significantly improve outcome in parolees and probationers with a history of opioid addiction compared to TAU alone. Participants will be randomized to either treatment as usual in community programs or monthly injections of depot naltrexone for six months with treatment as usual in community programs. The effectiveness of depot naltrexone has never been studied in opioid dependent parolees. all parolee subjects will be evaluated at baseline, while in treatment, and at 6, 12 and 18 month post entry time points. The primary study outcomes are retention in treatment, drug use, re-arrests, psychosocial and medical/psychiatric functioning, and economic costs and benefit costs of naltrexone.

What is being measured

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

  1. Relapse

    A relapse event was defined as 10 or more days of opioid use in a 28-day (4-week) period as assessed by self-report or by testing of urine samples obtained every 2 weeks; a positive or missing sample was computed as 5 days of opioid use.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Depot naltrexone and Treatment as Usual (TAU) in people with Opiate Addiction, 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 3 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 23 Oct 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 23 Oct 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?

Relapse (time frame: 6 months). 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 NCT00781898, which also lists 4 linked publications.

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 23 Oct 2017.
