Comparison of the Efficacy, Safety, and Relapse of ECT to ECT Plus Agomelatine for Depressed Patients

A Randomized, Double-blind, Comparison of the Efficacy, Safety, and Relapse of Electroconvulsive Therapy (ECT) to ECT Plus Agomelatine in the Treatment of Patients With Major Depressive Disorder

Our hypothesis is that using antidepressants during the ECT has a better efficacy and longer time to relapse/recurrence to the ECT without antidepressants. The purpose of this study is to compare the efficacy, safety, and time to relapse/recurrence of ECT to ECT plus agomelatine in the treatment of patients with major depressive disorder. Inpatients with major depressive disorder for ECT will be randomly assigned to double-blind treatment with placebo or agomelatine 50 mg/d.

Study Overview

• Status: Completed
• Conditions: Major Depressive Disorder
• Intervention / Treatment: Drug: Placebo; Other: electroconvulsive therapy; Drug: agomelatine

Detailed Description

Objective: Electroconvulsive therapy (ECT) is the safe and the most effective treatment for patients with major depressive disorder. It is still inconclusive whether antidepressants are continued during the course ot ECT. In terms of efficacy and safety, three essential questions arise: 1) does concomitant treatment improve the short-term antidepressant effects of ECT, 2) does concomitant treatment reduce the rate of early relapse/recurrence following ECT, 3) does concomitant treatment has more side effects? The purpose of this study is to conduct a clinical trial to compare the efficacy, safety, and time to relapse/recurrence of ECT to ECT plus agomelatine in the treatment of patients with major depressive disorder.

Methods: This is a prospective study. Inpatients with major depressive disorder for ECT will be randomly assigned to double-blind treatment with placebo or agomelatine 50 mg/d. After the ECT, the patients who meet the response criteria (i.e., at least a 50% reduction in symptom scores) or receive at least 6 treatments (i.e., acute phase) will receive the agomelatine 50 mg/d for 3 months (i.e., follow-up phase). The severity of depression, severity of anxiety, psychosocial functioning and side effects will be measured using the 17-item Hamilton Rating Scale for Depression (HAMD-17), the Clinical Global Impression-Severity (CGI-S), Depression and Somatic Symptoms Scale (DSSS), Zung's Depression Scale (ZDS), Hamilton Anxiety Rating Scale (HAM-A), Global Assessment of Functioning (GAF), Work and Social Adjustment Scale (WSAS), and UKU Side Effect Rating Scale before ECT, after every 3 sessions of ECT, at the end of acute ECT, and monthly during the 3-month follow-up period. Medical Outcomes Study Short-Form 36, Arizona Sexual Experiences Scale(ASEX), MINI Mental State Examination (MMSE), neuropsychological tests, and electroencephalography will be assessed before ECT, after ECT, and after the 3-month follow-up period. Questionnaire for patient attitudes about ECT after acute ECT will be completed. The Pearson chi-square test will be used to compare the response rate and remission (i.e., HAM-17≦7) rate between two groups. Analyses of group differences in efficacy will be performed by generalized estimating equations or ANCOVA. Survival analysis will be used to compare the time to response/remission and time to relapse/recurrence (i.e., HAM-D-17≧14 or CGI-S ≧4 or rehospitalization) after ECT between two groups.

Expected results: The results will provide evidence base for clinicians to decide to use antidepressants during ECT or not.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
17-item Hamilton Rating Scale for Depression (HAMD-17)	The HAMD-17 is widely used in clinical setting to evaluate depression symptoms in the past week. Higher total HAMD-17 scores (ranging from 0 to 52) indicate more severe depression.	up to month 3.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Clinical severity by Clinical Global Impression-Severity (CGI-S)	The CGI-S is developed for use in NIMH-sponsored clinical trials to provide a brief, stand-alone assessment of the clinician's view of the patient's global functioning prior to and after initiating a study medication. The CGI comprises one-item measures evaluating the severity of psychopathology from 1 to 7 and higher scores indicate higher severity.	In acute phase, the CGI-S is rated at baseline, and again at weeks 1, 2, 3, 4, 5 and 6 (or on early termination). In follow-up phase, the CGI-S is rated at months 1, 2, and 3.
Work and Social Adjustment Scale (WSAS)	The Work and Social Adjustment Scale (WSAS) is a 5-item self-rating scale designed to measure psychosocial functional impairment. Each item is scored from 0 (not affected at all) to 8 (severely affected).	In acute phase, the WSAS is rated at baseline, and again at weeks 1, 2, 3, 4, 5 and 6 (or on early termination). In follow-up phase, the WSAS is rated at months 1, 2, and 3.
UKU side effects rating scale	UKU side effects rating scale, with the score of each item ranging from 0 (none) to 3 (severe), is used to measure adverse events during the study period.	In acute phase, the UKU scale is rated at baseline, and again at weeks 1, 2, 3, 4, 5 and 6 (or on early termination). In follow-up phase, the UKU scale is rated at months 1, 2, and 3.
Electroencephalograph (EEG)	The EEG is used to analyze the change of electroencephalogram complexity. EEG The recording lasted about 3 minutes after habituation to environment, and the EEG technician monitored subject vigilance. Recordings are in 19 electrodes (Fp1, Fp2, F7, F3, Fz, F4, F8, T7, C3, Cz, C4, T8, P7, P3, Pz, P4, P8, O1, O2) in the standard 10-20 International placement with mastoid reference. The raw EEG signal is transposed to MATLAB software (MathWorks Inc., Natick, MA, USA) for processing. Each electrode complexity will be calculated.	In acute phase, the EEG is recorded at baseline and again at week 6 (or on early termination). In follow-up phase, the EEG is recorded at month 3.
Medical Outcomes Study Short-Form 36 (SF-36)	The SF-36 is used to assay the quality of life. Scores for the 8 SF-36 subscales range from 0 to 100, with a higher score representing better QOL.	In acute phase, the SF-36 is rated at baseline and again at week 6 (or on early termination). In follow-up phase, the SF-36 is rated at month 3.
Mini Mental State Examination (MMSE)	The MMSE used to assay the cognitive function. It consists of 30 points. Lower scores indicate poorer performance and greater cognitive impairment. The total score ranges from 0 to 30.	In acute phase, the MMSE is administered at baseline and again at week 6 (or on early termination). In follow-up phase, the MMSE is administered at month 3.
Arizona Sexual Experiences Scale (ASEX)	The ASEX is used to assay the sexual dysfunction. The ASEX taps five domains of sexual function using 6-point Likert scales scored from 1 (hyperfunction) to 6 (extreme hypofunction) to yield a total score ranging from 5 to 30.	In acute phase, the ASEX is rated at baseline and again at week 6 (or on early termination). In follow-up phase, the ASEX is rated at month 3.
Depression and Somatic Symptoms Scale (DSSS)	The DSSS, a self-rating scale, is used to assay the severity of depression. The DSSS contains 22 items. Item responses are ranked from 0 to 3, with higher scores corresponding to more severe depression.	In acute phase, the DSSS is rated at baseline, and again at weeks 1, 2, 3, 4, 5 and 6 (or on early termination). In follow-up phase, the DSSS is rated at months 1, 2, and 3.
The Wechsler Memory Scale (WMS).	The WMS is designed to measure different memory functions. Higher scores indicate higher memory functions.	In acute phase, the WMS is administered at baseline and again at week 6 (or on early termination). In follow-up phase, The WMS is administered at month 3.
