About this study
Official title: Pilot Study Probing the Antidepressant Effects of 0.5 mg/kg Intravenous Ketamine in Drug-resistant Depressed Patients (Unipolar Depression): Efficacy, Safety, Brain Function
Targeting the glutamatergic system to treat depression is a new and promising strategy based on studies at the molecular, synaptic, and neuronal level but also on results of studies conducted in animal models and first clinical studies involving depressed patients.Ketamine has been proposed as a novel approach to induce rapid antidepressant response. In this pilot project the investigators aim to introduce this novel and promising approach into clinical practice. Besides the assessment of clinical efficacy, the investigators will put a special emphasis on the assessment of ketamine-associated effects on brain function using fMRI and cognitive testing.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Ketamine in people with Major Depression, run by Markus KOSEL at 1 site in Switzerland.
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 13 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: stopped early, as of the sponsor's last update on 7 Dec 2015. 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 Switzerland. 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 was stopped early (reason given: End of funding of study). Results are not available in the source record.
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 of the MADRS score at baseline and after ketamine injection (time frame: 40, 80, 110, 230 min, 1, 2, 3, 6, 7, 10 d after ketamine 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 7 Dec 2015; AzTrials last refreshed its copy on 27 Oct 2026.
