Personalized rTMS for Resistant Depression

September 22, 2025 updated by: University Hospital, Strasbourg, France

Validation of Personalized Antidepressant Treatment by Neuromodulation - Pilot Study

The investigators hypothesize that personalizing the rTMS targets using functional MRI will increase its efficacy. The most dysfunctional regions or the most dysfunctional network will be stimulated homogeneously. Individualized rTMS will be compared to traditional rTMS procedure and to trans-cranial direct current stimulation (tDCS) in a randomized cross-over trial.

In this pilot study the primary outcome measure will be the correction of the MRI anomalies. Symptoms reduction and the proportion of remitters will be secondary outcome measurements.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Individualized rTMS (transcranial magnetic stimulation)

The target region will be defined by comparing the rCBF scan of the patient to a control population (n = 38). rCBF will be measured using the QUIPS2 arterial spin labeling sequence on a Siemens 3T Verio.

The therapeutic protocol will be design to correct the rCBF anomaly first by defining each point where to deliver the stimulation than the stimulation protocol for each point (180% of active motor threshold, 4-second 10 Hz train duration, with 26-second intertrain interval for a total of 3000 pulses). The whole target will be homogeneously stimulated.

The active motor threshold will be assessed. The procedure will be repeated twice a day for 10 days over 2 weeks.

Procedure consisting in personalizing the rTMS targets and stimulation pattern based on functional magnetic resonance imaging
Active Comparator: Classical rTMS (transcranial magnetic stimulation)
rTMS will be performed as usual using a figure-eight coil: Defining the active motor threshold. For each session positioning the coil on F3, stimulating at 180% of active motor threshold (10 Hz, 4-second train duration, and 26-second intertrain interval) for 37.5 minutes (3000 pulses per session), twice a day for 10 days over 2 weeks.
Procedure consisting in personalizing the rTMS targets and stimulation pattern based on functional magnetic resonance imaging
Active Comparator: Classical tDCS (transcranial direct current stimulation)
tDCS will be performed as usual: After controlling for skin healthiness, the anode and the cathode will be respectively placed over F3 and right shoulder. A commercial devices (MagStim), will deliver a constant current of 2 mA through 25 cm2 saline-soaked rubber sponges for 20 min per session. The procedure will be repeated twice a day for 10 days over 2 weeks.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change of rCBF anomalies
Time Frame: Difference between before (assessed once between D-7 to -1) and after (assessed once between D+15 to +21) each therapeutic protocol (D = day of the beginning of the protocol)

The target region will be defined by comparing the rCBF scan of the patient to a control population. rCBF will be measured using the average of 2 ∙ 3 (=6) measures of rCBF using QUIPS2 arterial spin labeling sequence on a Siemens 3T Verio. rCBF change of the target region will be compared before & after therapeutic protocol between the different procedures (ANOVA).

Functional connectivity map of the target region will be performed by extracting its average temporal course and looking at the region(s) which activity is correlated. Contrast map of each patient will be compared to the one of a control population submitted to the same analysis. Change in the number of above threshold voxels (F-test, p < 0.05 uncorrected, extension > 1 cm3) will be compared before & after therapeutic procedure (ANOVA). rCBF's change of the target region will be compared before & after therapeutic protocol between the different procedures (ANOVA).
