Run by University of Alberta · NCT05570344 · Data updated 2026-11-12

This study is testing if adding supportive text messages to a brain treatment can help adults with tough-to-treat depression feel better compared to just the brain treatment alone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older diagnosed with major depressive disorder who have failed at least two standard antidepressant treatments.

Probably not a fit

Patients under 18 or those with certain neurological or psychotic disorders may not benefit from this study.

What this trial studies

This multicenter pilot trial investigates the effectiveness of repetitive transcranial magnetic stimulation (rTMS) combined with a supportive text messaging program called Text4Support compared to rTMS alone in treating patients with treatment-resistant depression (TRD). Participants aged 18 and older, who have not responded to at least two standard antidepressant treatments, will be randomly assigned to one of the two treatment arms. The study will involve six weeks of active treatment followed by observation periods at one, three, and six months. The primary outcome will be measured using the Patient Health Questionnaire (PHQ-9) to assess changes in depression severity.

Why it matters

Potential benefit: If successful, this approach could provide a novel and effective treatment option for patients suffering from treatment-resistant depression.

How similar studies have gone: While the combination of rTMS and supportive text messaging is a novel approach, previous studies have shown rTMS to be effective for depression, suggesting potential for success.
