About this study

The overall is aim of this pilot study is to give a preliminary estimation of key parameters of the pharmacokinetics of a proper formulation of intranasal naloxone. These data will be used to design a well justified protocol for the final estimation of these parameters:

  • Preliminary estimation of bioavailability of this intranasal naloxone in human, healthy volunteers
  • Preliminary estimation of the maximum serum concentration (Cmax) of this formulation
  • Preliminary estimation of the time to maximum serum concentration (Tmax) of this formulation
  • Safety of the formulation
Conditions
Drug Overdose
Being tested
naloxone intranasal, naloxone intravenous

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • naloxone intranasalDrug

    If bioavailability is 20% or 50 %, the dose will be equivalent to the clinical range 0.4 - 1.0 mg given parenterally

  • naloxone intravenousDrug

    The parenteral dose reflects clinically used doses for overdoses (0.4 - 1.0 mg). A washout period of at least 3 days between each intervention. IV naloxone (Naloxone B. Braun 0.4mg/ml) administered slowly over 1-2 min in the recumbent position

What is being measured

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

  1. preliminary bioavailability of nasal naloxone

    measured as ratio of area under the time concentration curve for nasal over intravenous naloxone x 100. Plasma concentration data will be analyzed by non-compartmental techniques.

    Measured: 2 weeks

Secondary outcomes (2)
  1. time to maximum concentrations

    Measured: 2 weeks

  2. maximum concentration

    Measured: 2 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing naloxone intranasal and naloxone intravenous 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 2 inclusion and 4 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 Nov 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 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 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 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?

preliminary bioavailability of nasal naloxone (time frame: 2 weeks). 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 NCT01939444, 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 3 Nov 2021.
