Longitudinal look at how lasting TMS benefits can be predicted for depression

Official title: Longitudinal Study on the Sustainability of Transcranial Magnetic Stimulation Protocols - Biomarkers

Run by Hospital Center Guillaume Régnier · NCT07684911 · Data updated 2026-11-12

This study follows people with major depressive disorder who responded to prior rTMS to see what factors predict how long their response lasts.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with treatment-resistant unipolar or bipolar depression who previously responded to an rTMS course and can participate in MRI assessments and French-language questionnaires.

Probably not a fit

Patients who have not previously responded to rTMS or cannot complete MRI-based assessments may not benefit from this study.

What this trial studies

This observational study aims to identify biomarkers and factors associated with the durability of response to repetitive transcranial magnetic stimulation (rTMS) in adults with unipolar or bipolar depression. Participants are adults who previously benefited from a course of high-frequency rTMS and will undergo ongoing assessments, potentially including MRI, to track response durability over time. There are specific inclusion criteria around prior response, language, and capacity to consent, with safety exclusions for active suicidality or unstable medical conditions. The study seeks to inform personalized treatment planning and resource allocation by elucidating predictors of long-term rTMS efficacy. No interventional therapies are assigned beyond standard rTMS practice within the observational framework.

Why it matters

Potential benefit: findings could help tailor future rTMS plans to individuals likely to maintain benefit over time.

How similar studies have gone: Earlier work suggests neurophysiological and imaging biomarkers may relate to rTMS response, but durable prediction remains an area of active research with limited validation.

Inclusion Criteria:

* Patients aged 18 or older.
* Patients who have experienced treatment-resistant unipolar or bipolar depression and responded to a previous TMS course (response defined by a 50% reduction in MADRS score).
* Sufficient command of French to complete questionnaires and follow instructions during MRI assessments and TMS treatments.
* Willingness to comply with all study procedures, including availability for the duration of the study, and to communicate with study staff about adverse events and other clinically relevant information.
* Patients who have expressed their informed written consent to participate in the study.
* Person affiliated with a social welfare scheme or other scheme.

Non-inclusion Criteria:

* Current psychiatric comorbidity (suicidal risk, psychotic episode).
* Unstable somatic pathology: active cancer, unstabilized endocrinological pathology, untreated sleep apnea.
* For neuroimaging: Contraindications to magnetic resonance imaging (MRI) such as ferromagnetic metal in the body or severe claustrophobia
* Adults under legal protection (legal guardianship, conservatorship, trusteeship), persons deprived of their liberty
