Trial summary

Current treatments for opioid addiction would benefit by the addition of a non-opioid based treatment medication. Recent behavioral studies have shown that the neurokinin-1 (NK1) receptor is involved in opioid reward and withdrawal. Read more about this study

About this study

Official title: Clinical Laboratory Evaluations of Aprepitant for the Treatment of Opioid Dependence: Inpatient Test

Current treatments for opioid addiction would benefit by the addition of a non-opioid based treatment medication. Recent behavioral studies have shown that the neurokinin-1 (NK1) receptor is involved in opioid reward and withdrawal. This study proposes to study a potential non-opioid treatment, the clinically available, FDA approved, NK1 antagonist aprepitant, in opioid addicted patients. Based on the unique behavioral and pharmacological characteristics of opioid addiction, and what is known of the currently employed treatments, the investigators propose that the therapeutic mechanism of any potential opioid addiction treatment medication must include the ability to reduce opioid withdrawal. This is of particular importance during treatment initiation (eg. detoxification). In addition, for long-term treatment and relapse prevention, it is important to manage drug craving and inhibit the rewarding effects of opioids if patients do experience a slip. Therefore, the investigators propose to study aprepitant using human models of opioid withdrawal, craving and acute opioid reward and reinforcement. The investigators will also include a neuro-economics choice procedure paradigm.

What is being measured

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

  1. Opioid Withdrawal

    On the 4 dosing days, opioid withdrawal will be measured using the Clinical Opiate Withdrawal Scale (COWS) and the Subjective Opioid Withdrawal Scale (SOWS) at the following time points: 30 minutes pre-medication, 150 minutes post medication, 15 minutes post-challenge drug administration, 1 hour post- challenge drug administration, 2 hours post challenge drug administration and 3.5 hours post challenge drug administration

    Measured: 30 minutes pre-medication, 150 minutes post medication, 15 minutes post-challenge drug administration, 1 hour post- challenge drug administration, 2 hours post challenge drug administration and 3.5 hours post challenge drug administration

Secondary outcomes (2)
  1. Opioid Intoxication

    On the 4 dosing days, opioid intoxication will be measured using the Visual Anaglog Scale (VAS)at the following time points: 30 minutes pre-medication, 150 minutes post medication, 15 minutes post-challenge drug administration, 1 hour post- challenge drug administration, 2 hours post challenge drug administration and 3.5 hours post challenge drug administration

    Measured: 30 minutes pre-medication, 150 minutes post medication, 15 minutes post-challenge drug administration, 1 hour post- challenge drug administration, 2 hours post challenge drug administration and 3.5 hours post challenge drug administration

  2. Neuro-economic Choice Procedure

    A neuro-economics collaborative team will perform a neuro-economic choice paradigm procedure at 45 minutes post challenge drug dosing to determine the relative proportion and amount of a further dose of drug at 3.5 hours post challenge drug administration versus receipt of a variable amount of money

    Measured: 45 minutes post challenge drug dosing

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Aprepitant in people with Opioid Dependence, run by NYU Langone Health 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 9 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 Aug 2021. 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 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.

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.

What does the primary outcome measure?

Opioid Withdrawal (time frame: 30 minutes pre-medication, 150 minutes post medication, 15 minutes post-challenge drug administration, 1 hour post- challenge drug administration, 2 hours post challenge drug administration and 3.5 hours post challenge drug administration). 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 23 Aug 2021.
