SuicidePhase 2NCT03502551
ED Treatment of Suicidal Patients With Ketamine Infusion
A Phase 2 study testing Ketamine in people with Suicide and Suicidal Ideation, run by University of California, Davis at 1 site in United States.
Trial summary
This study aims to determine if a single intravenous (IV) dose of ketamine given in the emergency department (ED) can provide a long term reduction in suicidal ideation, lower time to ED discharge, and increase discharge to home or voluntary treatment facilities all while being safe.

About this study
This study aims to determine if a single intravenous (IV) dose of ketamine given in the emergency department (ED) can provide a long term reduction in suicidal ideation, lower time to ED discharge, and increase discharge to home or voluntary treatment facilities all while being safe.
Read the detailed description
Suicide has risen to the 2nd leading cause of death in Americans aged 10 to 34, and is the10th leading cause of death overall. Globally, the World Health Organization estimates one person dies of suicide every 40 seconds. Despite its lethality, no recognized acute treatments for suicidality exist. Recently, ketamine, an N-methyl-D-aspartate (NMDA) receptor agonist, has been shown to rapidly reduce suicidality in small studies in psychiatric settings. However, most patients with acute suicidal thoughts are treated initially in Emergency Departments (EDs). Delays in treatment have both short and long term impacts on recovery as patients spend longer time frames in an actively suicidal state.
Identifying a rapid and effective treatment for suicidal ideation that can be administered in the ED would have a profound impact on the emergent management of patients with suicidal thoughts. Ketamine is an FDA approved medication that is commonly used in EDs for multiple indications. EDs have the familiarity, facilities and personnel to safely administer IV ketamine.
Ketamine is regularly used in EDs in high doses for procedural sedation in adults and children. It is also used in high doses as a sedative for acutely agitated patients. In low-doses ketamine is frequently used for its analgesic properties and is considered safe.
Ketamine has also been safely used in the pre-hospital setting. In a recent joint policy statement of the American College of Emergency Physicians recommended the use of low-dose ketamine for pain in control with a safety profile comparable to other intravenous analgesia such as morphine.
Use of Ketamine to rapidly reduce suicidality may facilitate a safe and faster transition of acutely suicidal patients to outpatient treatment. Such treatment potentially shortens these patients' ED and hospital lengths of stay.

What is being measured
The primary outcome is the main question the study is designed to answer.
Suicidal ideation at 24 hours post-infusion
Suicidal ideation as measured by the Montgomery-Asberg Depression Scale (MARDS) will be assessed at 24 hours post-infusion of ketamine. The scale is a series of 10 questions each having a possible score of 0-6. Total scores are reported on a scale from 0-60, with lower numbers indicating less depression and higher numbers indicative of increasing depression.
Measured: 24 hours post-infusion
Incidence of Discharge to Outpatient vs. Inpatient Facilities
The investigators will collect information about what location patients enrolled in this study are discharged to (E.g. home, outpatient crisis residential facility, inpatient psychiatric hospital, admission to general hospital).
Measured: Through ED stay, an average of 53 hours
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]
Patients will be monitored for adverse events during the course of this study.
Measured: 1 week from enrollment.
Secondary outcomes (4)
Overall MARDS score
The MARDS will be administered regularly throughout the study and will serve as a measure of suicidal ideation. The scale is a series of 10 questions each having a possible score of 0-6. Total scores are reported on a scale from 0-60, with lower numbers indicating less depression and higher numbers indicative of increasing depression.
Measured: 1 hour, 3 days, and 1 week post-infusion
MARDS Suicidal Ideation (MARDS-SI) score
The MARDS will be administered regularly throughout the study and will serve as a measure of suicidal ideation. Item 10 on the MARDS serves to specifically measure suicidal ideation with a score of 4 or greater being considered to indicate marked suicidal ideations.
Measured: 1 hour, 3 days, and 1 week post-infusion
Scale for Suicide Ideation-5 (SSI5) score
The Scale for Suicide Ideation (SSI) will be administered regularly throughout the study and will serve as a measure of suicidal ideation. Items 1-5 on the SSI serves to specifically measure suicidal ideation. Each of the five questions on the scale have three possible answers with scores ranging from 0 (no suicidal ideation) to 2 (increased suicidal ideation). To compute the SSI5, the scores from each of the five questions are added together to give an overall score from 0-10, where 0 is no suicidal ideation and 10 is increased suicidal ideation.
Measured: 1 hour, 3 days, and 1 week post-infusion
ED length of stay
The investigators will measure the amount of time that patients in this study remain in the ED before being discharged or transferred.
Measured: Through ED stay, an average of 53 hours

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Ketamine in people with Suicide and Suicidal Ideation, run by University of California, Davis 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 3 inclusion and 11 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: withdrawn, as of the sponsor's last update on 1 May 2019. 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. 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 withdrawn before enrolling participants, so there are no results.
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?
Suicidal ideation at 24 hours post-infusion (time frame: 24 hours post-infusion). The study lists 3 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 NCT03502551, which also lists 20 linked publications.
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 1 May 2019.
