Parcel-guided rTMS for Major Depressive Disorder

December 17, 2025 updated by: Soterix Medical

Phase-2 Trial of Parcel-guided rTMS for Major Depressive Disorder

Study comparing standard repetitive transcranial magnetic stimulation (rTMS) for Depression to a novel targeting approach using brain surface parcellation to locate a specific brain target.

Study Overview

Detailed Description

Standard rTMS treatment often uses the "Beam-F3" targeting approach to locate a brain region known as the left dorsolateral prefrontal cortex (lDLPFC). However, Beam-F3 does not take into account interindividual variation in brain anatomy. Researchers as Columbia University have found a more accurate and personalized approach that uses MRI-based brain surface parcellation to locate the specific subregion of the lDLPFC most ideal for rTMS treatment. Our study is comparing standard rTMS (Beam-F3) to parcel-guided rTMS for patients with treatment resistant depression.

  • Meets criteria for claustrophobia
  • Recent drug or alcohol use disorder with DSM-5 specifier of moderate or severe within 6 months, or mild within 2 months; or lifetime history of IV drug use A- ctively suicidal, as defined by expressive ideation with a plan or with suicidal ideation that requires immediate medical or treatment intervention.
  • Neurological or neuromuscular disorder
  • Requires medications for a general medical condition that contraindicate the TMS treatment
