Trial summary

Opioid overdoses have in the last decade counted for about 230 untimely deaths annually in Norway. The government is currently implementing a strategy for combating this epidemic. Among the actions promoted in this strategy is the distribution of naloxone for intranasal administration. Read more about this study

About this study

Official title: Bioavailability of Nasal Naloxone and Injected Naloxone Compared. A Randomized, Open Label, 4-way Cross-over Study

Opioid overdoses have in the last decade counted for about 230 untimely deaths annually in Norway. The government is currently implementing a strategy for combating this epidemic. Among the actions promoted in this strategy is the distribution of naloxone for intranasal administration. Such administration of naloxone is currently being implemented and tried out around the world, but very little has been done to pharmacologically study this new route of administration of this well known drug, and only 3 open label randomized controlled trials (RCTs) have been conducted. A recent guideline from the WHO on community management of opioid overdoses is a comprehensive review of many of the aspects the investigators cover in our research.

Regarding both dosage, routes of administration of naloxone and care of these patients in the pre hospital setting. The WHO calls for nasal formulations with a higher concentration, as well as focuses on the current wide spread off label use of nasal naloxone as a problem and identifies several research questions of critical importance and very low evidence.The current study, together with our research group's previous and future studies, aims to provide data for the development of a medicinal product with marketing authorisation for use in pre-hospital overdoses. This to contribute to public health measures for opioid users and those around them.

What is being measured

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

  1. Difference in Peak plasma concentration (Cmax)

    Cmax will be compared for single dose IN, IM and IV naloxone

    Measured: 4 days

  2. Difference in systemic exposure: Area under the plasma concentration versus time curve (AUC-0last)

    AUC 0-last will be compared for single dose IN, IM and IV naloxone

    Measured: 4 days

  3. Difference in dose adjusted systemic exposure: Area under the plasma concentration versus time curve (AUC-0inf)

    AUC0-inf will be compared for single dose IN, IM and IV naloxone

    Measured: 4 days

  4. Difference in time at which the Cmax is observed (Tmax)

    Tmax will be compared for single dose IN, IM and IV naloxone

    Measured: 4 days

Secondary outcomes (3)
  1. Dose proportionality

    assessed by comparing systemic exposure (AUC0-last) following one and two doses of 1.4 mg of IN naloxone in the same nostril.

    Measured: 4 days

  2. Absolute bioavailability

    assessed by comparing dose adjusted systemic exposure (AUC0-last) of IN and IV naloxone

    Measured: 4 days

  3. Relative bioavailability

    assessed by comparing dose adjusted systemic exposure (AUC0-last) of IN and IM naloxone

    Measured: 4 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Intranasal (IN) naloxone 1x, Intranasal (IN) naloxone 2 and Intravenous (IV) naloxone in people with Drug Overdose, run by Norwegian University of Science and Technology at 1 site in Norway.

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 11 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 3 Feb 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 Norway. 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 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?

Difference in Peak plasma concentration (Cmax) (time frame: 4 days). The study lists 4 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 3 Feb 2017.
