What is being measured

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

  1. Pharmacokinetic parameter [maximum serum concentration - Cmax]

    The primary endpoints of the study are the pharmacokinetic parameter, maximum serum concentration [Cmax], of naltrexone and naloxone when administered and in combination.

    Measured: 12 days

  2. Pharmacokinetic parameter [area under the plasma concentration time curve - AUCO-t]

    The primary endpoints of the study are the pharmacokinetic parameter, area under the plasma concentration time curve [AUCO-t] of naltrexone and naloxone when administered and in combination.

    Measured: 12 days

  3. Pharmacokinetic parameter [area under the plasma concentration curve from zero to infinity - AUCO-inf]

    The primary endpoints of the study are the pharmacokinetic parameter, area under the plasma concentration curve from zero to infinity [AUCO-inf] of naltrexone and naloxone when administered and in combination.

    Measured: 12 days

Secondary outcomes (6)
  1. Adverse Events

    To assess and document any adverse events measures

    Measured: 15 days

  2. Vital Sign - Heart Rate

    To assess and document heart rate before and after intranasal dosing

    Measured: 12 days

  3. Vital Sign - Blood pressure (diastolic)

    To assess and document blood pressure (diastolic) before and after intranasal dosing

    Measured: 12 days

  4. Vital Sign - Blood pressure (systolic)

    To assess and document blood pressure (systolic) before and after intranasal dosing

    Measured: 12 days

  5. Vital Sign - Respiration Rate

    To assess and document respiration rate before and after intranasal dosing

    Measured: 12 days

  6. Electrocardiogram

    Twelve-lead ECGs performed according to standard procedures that will assess P wave, PR interval, QRS complex, ST segment, T wave and QT interval.

    Measured: 12 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Naltrexone, Naloxone and Naltrexol in people with Opioid-use Disorder, run by National Institute on Drug Abuse (NIDA).

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 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: finished, as of the sponsor's last update on 14 Sep 2020. Status can change between updates, so confirm with the study contact before making plans.

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 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?

Pharmacokinetic parameter [maximum serum concentration - Cmax] (time frame: 12 days). The study lists 3 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 14 Sep 2020.
