    A single dose of 1.2 mg/kg of atomoxetine administered orally

  • KetamineDrug

    Also called Ketalar

    A single dose of ketamine (approximately 60 mg) administered as an intravenous infusion

  • Cold pressor testOther

    30-45 min cold pressor test of the foot

  • InsulinDrug

    Also called Insulin Actrapid

    Insulin administered as an intravenous infusion to induce hypoglycemia

  • PlaceboDrug

    A single dose of placebo (capsules) administered orally

What is being measured

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

  1. Receptor occupancy

    PET tracer (interventional drug) uptake in the brain is measured for 30 minutes by PET after various pharmacological and physiological pre-treatments.

    Measured: 30 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Atipamezole, Atomoxetine and Ketamine in people with Healthy, run by University of Turku at 2 sites in Finland.

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 5 inclusion and 26 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 18 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Finland. 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?

Receptor occupancy (time frame: 30 minutes). 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 18 Feb 2013.
