Basic Information

• Recruitment Status: RECRUITING

• Study Completion Date: 2026-03-23

Brief Summary

The REACH-tDCS study will evaluate the safety and efficacy of a noninvasive, at-home self-administered Sooma tDCS brain stimulation treatment for Major Depressive Disorder. The study uses randomized, blinded, placebo controlled design. The participants are assessed with video interviews and self-reports during the study, which lasts for 10 weeks followed by an optional continuation period.

Detailed Description

The study stages include: screening, eligibility evaluation, randomization to active or sham arm (1:1), the first treatment period (weeks 1-10) with sham-control and the optional open-label phase (weeks 11-20) where all treatments will be in active mode.

Conditions

Major Depressive Disorder (MDD)

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: QUADRUPLE

Study Groups

Active treatment

Group Type: EXPERIMENTAL

Transcranial direct current stimulation

Intervention Type: DEVICE

In tDCS treatment session electrical current (2 mA) is applied for 30 minutes through two electrodes placed on top of scalp to modulate neural activity.

Sham treatment

Group Type: SHAM_COMPARATOR

Sham transcranial direct current stimulation

Intervention Type: DEVICE

Sham treatment mimics the active device use and the experiences from the active stimulation while minimizing active effects.
