Clinical Trial Summary

The goal of this randomized controlled trial is to he effectiveness of two different TMS techniques in TRD, repetitive TMS (rTMS) and deep TMS (dTMS). The main questions it aims to answer are:

type of study: clinical trial participant population/health conditions : Major Depressive Disorder To assess the superiority of dTMS over rTMS in TRD To evaluate the predictive capacity of scalable candidate biomarkers Participants will be randomly allocated to one of the two intervention groups (rTMS or dTMS).

Description:

The primary aim of this trial is to compare the effectiveness of two different TMS techniques in TRD, repetitive TMS (rTMS) and deep TMS (dTMS). Compared to rTMS, dTMS delivers a broader magnetic field, which in turn reduces coil positioning error and maximizes the probability of optimal cortical stimulation. A past RCT comparing both approaches found a greater depression score decrease and response/remission rates for dTMS, but was short of reaching significance for remission rates (primary outcome). Critical components of this RCT were suboptimal, including too few treatment sessions and insufficient statistical power, both of which could have obscured an actual difference between modalities. Proof of a more effective type of TMS over another would translate into increased odds of improvement for TRD patients who live with a chronic and disabling illness.

Eligibility

Inclusion Criteria:

• Diagnosis of Major Depressive Disorder, at least moderate intensity, single or recurrent episode

• HRSD-17 score of at least 18

• No improvement to at least two adequate courses of antidepressants (based on the ATHF) or were unable to tolerate at least two separate trials of antidepressants of inadequate dose and duration

• On a stable antidepressant regimen for the past four weeks before screening

Exclusion Criteria:

• Having previously received TMS;

• Substance use disorder within the last three months

• Diagnosis of bipolar or psychosis spectrum disorder
