Accelerated intermittent theta-burst stimulation for depression with post‑COVID‑19 condition

Pilot Study on the Effects of Intensified Repetitive Transcranial Magnetic Stimulation on Immunological Blood Parameters in Patients With Depression and Comorbid Post-COVID-19 Condition

Not applicable Interventional Max-Planck-Institute of Psychiatry · NCT07197138

This will test whether two different schedules of intermittent theta-burst stimulation (accelerated TMS) reduce depressive symptoms and inflammation in adults aged 18–65 who have depressive disorder plus post‑COVID‑19 condition.

What this trial studies

This monocentric, randomized pilot at the Max Planck Institute of Psychiatry in Munich compares two iTBS schedules delivered to the left dorsolateral prefrontal cortex: a standard schedule (one session per day over six weeks) and an intensified schedule (six sessions per day over five consecutive days), with both arms receiving 30 active sessions at 90% resting motor threshold using a PowerMAG 100 ppTMS. Participants are adults with at least moderate depression (BDI-II ≥ 20) and a comorbid WHO-defined post‑COVID‑19 condition on stable psychotropic medication. Primary outcomes include changes in circulating immunological markers (CRP, TNF, IL-1β, IL-6) and depressive symptoms measured by the BDI-II and clinician-rated Montgomery–Åsberg scale. The trial is a randomized pilot intended to explore biological and clinical signals rather than provide definitive efficacy results.

Who should consider this trial

Good fit: Adults aged 18–65 with at least moderate depressive disorder (BDI-II ≥ 20), a comorbid post‑COVID‑19 condition per WHO criteria, capacity to consent, and a stable psychopharmacological regimen are the intended participants.

Not a fit: People who are pregnant or breastfeeding, have acute suicidality, psychosis, ongoing substance abuse, severe neurological disorders, current benzodiazepine/Z‑drug treatment, cognitive impairment preventing consent, or are outside the 18–65 age range are unlikely to be eligible or to benefit from participation.

Why it matters

Potential benefit: If successful, the approach could offer a faster or more effective TMS schedule that improves depressive symptoms and reduces inflammatory markers in people with post‑COVID‑19 condition.

How similar studies have performed: Accelerated iTBS and other accelerated TMS schedules have shown promising antidepressant effects in prior depression studies, but their immune‑modulating effects and specific use in post‑COVID‑19 condition remain largely novel and untested.
