Comparative Effectiveness of ECT vs. KETAMINE Over the Lifespan

Phase 4
Conditions
Acute Suicidal Depression (ASD)
Interventions
Device: Electroconvulsive therapy (ECT)
Drug: Subanesthetic dose intravenous ketamine (KET)
Registration Number
NCT06034821
Lead Sponsor
Brigham and Women's Hospital
Brief Summary

This study is a randomized open-label single-blind non-inferiority comparative effectiveness study of ECT vs. KET for the treatment of Acute Suicidal Depression (ASD).

Detailed Description

There is a crisis in the treatment of the imminently suicidal patient. Acute Suicidal Depression (ASD) is a life-threatening illness which requires rapid relief. A number of behavioral programs with varying efficacy are available for prevention of suicide. However, once acute suicidal depression has set in, its treatment is woefully inadequate in the current health system despite availability of efficacious treatments. Patients suffering from ASD are usually admitted as inpatients for safety and started on oral antidepressants (which can take 6 - 12 weeks to have an effect) and given nursing care. They are then discharged from the hospital, usually within 4 -5 days, as soon as immediate safety concerns are ameliorated. Essentially, patients do not receive any specific rapidly acting treatment for their suicidal depression. As The immediate post-discharge period has been shown to be of the highest risk for repeat suicide attempts and completed suicides. One important reason for the inadequate treatment of ASD is the lack of large-scale comparative studies of efficacious treatments such as electroconvulsive therapy (ECT) and subanesthetic dose intravenous ketamine (KET). In the absence of data to guide rational treatment choice, neither treatment is being used adequately. Clinicians are less likely to recommend these treatments in the absence of evidence to base their decision regarding which treatment to give first and under what circumstances. Patients are reluctant to choose between these treatments due to uncertainty regarding efficacy and apprehension regarding side effects and social stigma. Finally, in the absence of effectiveness data, hospital administrators and third-party payers are reticent about committing material and financial resources for these services leading to inaccessibility. Hence, there is a critical need for a large-scale comparative effectiveness trial of ECT vs. intravenous ketamine for rapid reversal of ASD to provide rational guidance for all stakeholders.

This study will address this significant clinical dilemma by conducting a large scale (N = 1500) non-inferiority randomized comparative effectiveness trial of ECT vs. KET for rapid treatment of acute suicidal major depression (ASD) across the lifespan.

Primary Outcome Measures
NameTimeMethod
Scale for Suicidal Ideation (SSI)Six weeks

The Scale for Suicidal Ideation (SSI is excellent in terms of test construction and psychometrics (validity and reliability). It has been shown that a SSI score \>6 has been found to be predictive of suicide within 6 months of discharge from hospital. At the end of treatment, patients will be assessed for remission of suicidality which is defined as a SSI score \<4 i.e. no clinically significant suicidal ideation70. A stringent criterion for remission was chosen as ASD is a life-threatening illness and full remission should be the treatment goal.
