About this study

This project seeks to identify the acute and longer-term impact of a single dose of intravenous ketamine among suicidal patients referred for psychiatric consultation/liaison in the medical inpatient setting. The investigators will then test whether ketamine's rapid effects can be extended by introducing helpful information delivered by a computer-based training protocol. This work could ultimately lead to the ability to treat suicidality more efficiently and with broader dissemination by rapidly priming the brain for helpful forms of learning.

Read the detailed description

NOTE: In the course of this pilot study, both the primary and secondary outcome measures were supplemented to provide additional, complementary information on the clinical effects of the study interventions, based on confirmation (through study team experience) of the feasibility of acquiring such additional information in the context of our study population, setting, and design.

Why it stopped: Midway through this pilot study, funding was obtained to support a much larger study of the same interventions in this clinical population. Therefore the pilot study was halted so as not to compete with enrollment for the larger study.

Limitations and caveats (from the sponsor): Pilot study leading to small numbers of patients in each treatment arm. Descriptive statistics are reported without statistical analysis to directly compare groups, given the small number of patients within each group leading to low statistical power.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Intravenous ketamine and Cognitive training in people with Suicide, Attempted, run by Rebecca Price at 1 site in United States.

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 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: stopped early, as of the sponsor's last update on 22 Jul 2024. 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 United States. 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. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Montgomery Asberg Depression Rating Scale (time frame: infusion +24 hours). The study lists 12 primary outcomes in all. 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 NCT04154150.

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 22 Jul 2024; AzTrials last refreshed its copy on 6 Nov 2026.
