About this study

Healthy adult men who abuse opioids and are physically dependent on them will be invited to participate in a study to examine the ability of NT-814, a neurokinin (NK) antagonist at the 1 and 3 receptor subtypes, to alter the abuse liability of oxycodone.

Read the detailed description

After completing the screening process, participants will be scheduled for admission onto the General Clinical Research Unit on 5-South for a 13-week study. During Week 1, participants will be detoxified from opioids. During Week 2 after the detoxification period, participants will be randomized to receive one of four maintenance doses of NT-814. During Weeks 3-4 participants may receive oxycodone during laboratory sessions and will complete a cue exposure session involving presentation of neutral and drug cues. Participants then will have the opportunity to self-administer drug by making clicks on a computer mouse. Weeks 2, 5, 8, and 11 will be medication stabilization weeks following by testing during Weeks 3-4, 6-7, 9-10, and 12-13. At the conclusion of the study, participants will be given an exit interview during which the study will be described. Those who are interested in treatment for their drug use at the end of the study will be offered referrals to studies at our Substance Treatment and Research Service or other treatment providers.

What is being measured

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

  1. Percentage of oxycodone choices

    Percentage of drug (versus money) choices in each study arm will be our primary outcome measure.

    Measured: 1 week

  2. Average visual analog scale ratings of "I like the choice"

    Average ratings of oxycodone liking in each study arm will be obtained.

    Measured: 1 week

Secondary outcomes (1)
  1. Average visual analog scale ratings of "I want heroin"

    Average ratings of "I want heroin" in each study arm will be obtained.

    Measured: 1 week

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing NT-814 50 mg, NT-814 100 mg and NT-814 200 mg in people with Opioid Use Disorder, 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 7 inclusion and 5 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 Aug 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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Percentage of oxycodone choices (time frame: 1 week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

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 4 Aug 2020.
