The Effectiveness and Safety of Esketamine in Modified Electroconvulsive Therapy

Early Phase 1
Conditions
Esketamine
ECT
Depression
Interventions
Other: Saline
Registration Number
NCT04777110
Lead Sponsor
First Affiliated Hospital of Chongqing Medical University
Brief Summary

A multicenter, randomized, controlled, single blind clinical trial on the efficacy and safety of esmketamine injection in electroconvulsive therapy

Objective to evaluate the efficacy and safety of esmketamine injection in the treatment of non convulsive electroconvulsive therapy

Participants: Patients with depression receiving MECT

The research drug was esketamine injection

The study design was a multicenter, randomized, single blind, parallel controlled trial

25 mg / kg as the experimental group. The normal saline group was the control group (0.05 ml / kg).

The sample size was estimated according to the main efficacy index (remission rate) of this study. It was assumed that the remission rate of the esketamine injection group was better than that of the control group. The parameters were set as test level α = 0.05, unilateral, β = 0.8, the cut-off value was 6%, the experimental group: the control group was 1:1, according to the results of previous clinical trials and combined with literature, the remission rate of the control group was 69%, 159 cases in each group, considering the 20% shedding rate, 198 cases in the experimental group and 198 cases in the control group were selected.

1. experimental group

The patients were given intravenous injection of 0.25 mg / kg esketamine, 1.5 mg / kg propofol and 1 mg / kg succinylcholine in turn. After anesthesia, the patients were given electroconvulsive therapy

2. In the control group

The patients were given 0.05ml/kg of normal saline, 1.5mg/kg of propofol and 1mg / kg of succinylcholine. After anesthesia, the patients were given electroconvulsive therapy

Efficacy evaluation 1. Main efficacy indicators

Remission rate of depressive symptoms after MECT treatment

Remission was defined as two consecutive hdrs-24 scores ≤ 10 after receiving MECT

Definition rate of remission rate: the proportion of patients with remission of depressive symptoms in this group

GroupInterventionDescription
Saline injection group(0.05ml/kg)SalineThe main anesthesiologist standing on the right side of the patient sequentially injects normal saline (0.05ml/kg), and 1 minute later injects propofol (1.5 mg/kg), the injection time is 30 seconds
Esketamine injection group (0.25mg/kg)EsketamineThe main anesthesiologist standing on the right side of the patient gave successive injections of esketamine (0.25 mg/kg), and 1 minute later, injected propofol (1.5 mg/kg) for 30 s
Primary Outcome Measures
NameTimeMethod
Relief rate of depressive symptoms after MECT treatmentimmediately after the end of each ECT procedure

After the patient received MECT treatment, the HDRS-24 score ≤ 10 points for two consecutive times

Secondary Outcome Measures
NameTimeMethod
Treatment re-ignition ratewithin 4 months of patients in remission

Re-ignition is defined as an increase in HDRS-24 score of ≥ 10 points within 4 months of patients in remission. The re-ignition rate is defined as the proportion of re-ignition patients in remission patients.

Severe suicidal tendency elimination ratethrough treatment completion, an average of 18 days

Severe suicidal tendency is defined as the suicide item score in HDRS-24 ≥ 3 points. The elimination rate of severe suicidal tendency was defined as the proportion of patients with suicide score=0 after treatment in the proportion of patients with severe suicidal tendency

Treatment response ratethrough treatment completion, an average of 18 days

Response is defined as two consecutive HDRS-24 scores ≤ 50% before treatment after receiving MECT treatment. Effectiveness is defined as the proportion of patients in the group that are treated effectively

Treatment recurrence rateup to 4 months

The HDRS-24 score increased by ≥10 points after 4 months for patients whose recurrence is positioned as remission. The recurrence rate is defined as the proportion of relapsed patients in remission.

Changes in cognitive functionImmediately after the end of ECT, four months and six months after the end of the entire treatment course

Montreal Cognitive Scale (MoCA) assessment

HDRS-24 score after each MECTImmediately after the end of ECT, four months and six months after the end of the entire treatment course

HDRS-24 score after each MECT
