About this study
Official title: Buprenorphine/Naloxone Treatment for Opioid Dependence-Experiment I(2)
The purpose of this study is to compare the clinical efficacy of daily vs. 3-day (MWF) buprenorphine/naloxone combination tablet administration and determine whether outcomes are improved when using a 3-day schedule in which all doses are ingested at the clinic vs. one in which take-home doses are given on intervening days.
Read the detailed description
Mon/Wed/Fri dosing with the 8 mg buprenorphine/naloxone tablet is as safe and effective as daily dosing and is preferred by patients to daily dosing. Multiple doses of the combination tablet (e.g. 16mg, 24mg) are well tolerated by patients. A 3 day schedule with take-outs is as effective as a 3-day schedule in which all medication is ingested at the clinic

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 1 inclusion and 1 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The record says: withdrawn, as of the sponsor's last update on 4 May 2017.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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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The study was withdrawn before enrolling participants, so there are no results.
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?
Drug use. The study lists 5 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 NCT00000327, 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 4 May 2017; AzTrials last refreshed its copy on 8 Nov 2026.
