In this proof of concept study, the investigators plan to administer iv ketamine interleaved with Electroconvulsion Therapy days.
Patients with treatment resistant depression who are deemed to be eligible for ECT treatment will randomly be assigned to either ketamine or active placebo.
Trial DetailsThe study will compare the effects of standard ketamine dosing with an active placebo arm. Hypothesis 1: The investigators hypothesize that interleaved Electroconvulsive Treatment and active ketamine treatment will lead to a meaningful clinical improvement compared to Electroconvulsive Treatment and placebo treatment arm. Hypothesis 2: The investigators hypothesize that interleaved Electroconvulsive Treatment and active ketamine treatment will attenuate cognitive side effects. Methods and Design: Patients with treatment resistant depression who are deemed to be eligible for Electroconvulsive Treatment will randomly be assigned to either ketamine or active placebo Electroconvulsive Treatments: All patients (independent of their depression scores) will receive the same Electroconvulsive Treatment parameters: Bi-frontal brief pulse (0.5 miliseconds) Electroconvulsive Treatment administered by using Thymatron Electroconvulsive Treatment machine. Study blinding: Neither the patients, nor the treating psychiatrist or the nurse will be aware of the patient's assigned arm. The success of blinding will be tested after each ketamine treatment with a questionnaire given to the subject, raters, and treating physician.

Measures UsedHamilton Depression Rating Scale
