Condition or disease | Intervention/treatment | Phase |
---|---|---|
Major Depressive Disorder | Device: Transcranial Direct Current Stimulation Device: Placebo-simulation of transcranial direct current stimulation Drug: Fluoxetine Tablets | Phase 2 Phase 3 |
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 172 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | A multicentric, randomized, clinical trial, phase 2/3 of superiority, with two parallel arms, comparative, controlled with placebo, in which changes in a major depressive disorder scale will be assessed (change in CDI score measured at week 10 compared with initial score) comparing with basal score and between the two groups (>40% measured at 2 weeks, 1,2, 3 months of treatment). |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | In addition some of the personnel (evaluators, data analyst, result analyst) will be blinded in order to increase the internal validity of our study. A blind person is considered by the person that apply the intervention. |
Primary Purpose: | Treatment |
Official Title: | Assessment of Efficacy and Safety of Anodal Transcranial Direct Current Stimulation (TDCS) in Pediatric and Teenage Patients With Major Depressive Disorder During COVID-19 Pandemics |
Estimated Study Start Date : | October 2021 |
Estimated Primary Completion Date : | August 2022 |
Estimated Study Completion Date : | September 2022 |

Arm | Intervention/treatment |
---|---|
Experimental: tDCS arm
Participants receive 10 consecutive sessions followed by 1 session per week 10 weeks of tDCS (30 minutes and 2 mA) + fluoxetine (10 mg daily 2 weeks followed by 20 mg daily).
|
Device: Transcranial Direct Current Stimulation
Participants receive 10 consecutive sessions followed by 1 session per week 10 weeks of tDCS (30 minutes and 2 mA). Anodal stimulation will be applied on F3 according to the intentional 10/20 system, and the cathode will be applied on the contra lateral position (F4).
Other Names:
Drug: Fluoxetine Tablets Every patient will receive 10 mg of fluoxetine daily the first 2 two weeks, followed by 20 mg daily.
Other Name: Antidepressants |
Placebo Comparator: Control arm
Participant receive 10 consecutive sessions followed by 1 session per week 10 weeks of placebo (30 minutes of placebo-simulation tDCS) + fluoxetine (10 mg daily 2 weeks followed by 20 mg daily).
|
Device: Placebo-simulation of transcranial direct current stimulation
Participants receive 10 consecutive sessions followed by 1 session per week 10 weeks of placebo (30 minutes of placebo-simulation tDCS). Placebo will be administered using the same stimulation parameters and the active treatment position of the electrodes, but current wil be aborted 30 seconds after the ascending slope has begun. Drug: Fluoxetine Tablets Every patient will receive 10 mg of fluoxetine daily the first 2 two weeks, followed by 20 mg daily.

- Change of Children Depression Inventory score from the beginning to the end of the study [ Time Frame: At the beginning of the study and at the end of weeks 2, 4, 8, and 12 ]It is one of the most widely used self-applied scales to assess depressive symptoms in children and teenagers. The scale consists of 27 items, each item with 3 response options, where 0= absence of symptoms, 1= moderate symptoms, and 2= severe symptoms. The total score ranges from 0-54. The scale manual contains the psychometric properties reported by the author. It is recommended for use in children from 7-17 years old. a SCORE OF 20 was established as a cut-off point for indicating depression problems
- Change of Columbia-Suicide Severity Rating Scale score from the beginning to the end of the study [ Time Frame: At the beginning of the study and at the end of weeks 2, 4, 8, and 12 ]The C-SSRS is a semi-structured interview which collects the onset, severity and frequency of behavior and thoughts related to suicide during the assessement period. Therefore, 4 constructs are measured.
- Change of Young Mania Rating Scale score from the begining to the end of the study [ Time Frame: At the beginning of the study and at the end of weeks 2, 4, 8, and 12 ]
It is an instrument for quantifying mania symptoms that consist of 11 items, each one with 5 response options, which reflect higher score if great intensity. It is applied by the clinician and is based on the subjective report of the patient during 48 hrs prior to the evaluation, as well as on the observation of the patient's behavior during the interview. The patient selects the intensity level of the symptom for each item with an option from 0 to 4.
The total range of the scale from 0-60 points where higher scores indicate a greater degree of manic characteristics; the minimum score to define new-onset mania or hypomania is 8 points at the end of the weeks 2, 4, 8 and 12 to assess mania or hypomania during the clinical trial.

Ages Eligible for Study: | 10 Years to 17 Years (Child) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Major Depressive Disorder (MDD) diagnosed through the clinical interview based on the Affective Disorders and Schizophrenia Agenda for schoolchildren-current version and for life K- SADS-PL for its acronym in English, with a single or recurrent episode lasting ≥4 weeks.
- The current depressive episode must have a duration of less than 5 years and be at least greater than 2 months in which the patient meets the operational definition of MDD from the DSM-V.
- CID scale with values equal to 17 or higher in the clinical evaluation.
- No use of another medication during the intervention days.
- They should not be taking antidepressants at the beginning of the study (last 4 weeks) or it must have passed the adequate time of "washing"/ clearance of antidepressant drugs established as 5 or more biological half-lifes or 5 days before the randomization.
- To be able and willing to give their informed consent, both, the parent or tutor and the participant who is between the ages of 14-17 years. In the age group of 10-13 years the assent of the patient and the consent of the parent or tutor.

- Does NOT sign or is unable to sign informed consent or legal tutors/parents do not consent.
- Clinical condition or anomaly, which in the researcher's opinion, compromises patient´s safety or data quality.
- Uncontrolled co-existent medical condition, progressive cerebral disorder, severe systemic diseases, symptomatic disease, cardiac disease, skin chronic diseases or damaged scalp which could interfere with tDCS stimulation.
