Early use of rTMS vs an SSRI for non-treatment resistant depression

Official title: Repetitive Transcranial Magnetic Stimulation (rTMS) as an Early Intervention in Major Depression (MD) Compared to Antidepressant Selective Serotonin Reuptake Inhibitor (SSRI) Medication (Early-TMS)

Run by University Hospital Tuebingen · NCT06545474 · Data updated 2026-11-12

This study compares four weeks of bilateral theta burst stimulation (rTMS) to a four-week SSRI for adults with a first-episode, non-treatment-resistant major depressive disorder to see which works better and has fewer side effects.

Is this trial a fit for you?

Likely a good fit

Adults 18–65 with moderate to severe, DSM-5 major depressive disorder, no prior antidepressant treatment, MADRS ≥ 20, episode duration 2 weeks to 2 years, and no exclusionary comorbidities.

Probably not a fit

Patients with treatment-resistant depression, psychotic features, significant comorbidities, or contraindications to rTMS or SSRI therapy may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, multicenter phase 2 trial enrolling adults with moderate to severe major depressive disorder who have not previously received antidepressants. In stage I, participants are randomly assigned to 4 weeks of bilateral theta burst stimulation or an SSRI antidepressant. After stage I, therapy response guides stage II, which may continue the same treatment as maintenance, switch to the other treatment, or tailor based on remission and patient preference. The primary outcome compares treatment arms on response status using the MADRS after 4 weeks. The study aims to determine if 4 weeks of bilateral TBS is not inferior to standard SSRI treatment in efficacy and tolerability. Safety and tolerability data will also be collected throughout the trial.

Why it matters

Potential benefit: If successful, this approach could offer an effective non-drug option or a viable alternative for early treatment of depression with potentially different side effect profiles.

How similar studies have gone: Prior non-invasive brain stimulation studies have shown potential benefits, but direct non-inferiority data to SSRIs in this specific early-treatment, non-TRD population are limited.
