Trial Outcomes & Findings for rTMS for MDD: 5.5cm Rule vs. F3 Targeting (NCT NCT03378570)

NCT ID: NCT03378570

Last Updated: 2025-02-03

Results Overview

Overall change in total Patient Health Questionnaire 9-Item Assessment score from pre to post-treatment assessment, comparing results of 2 active groups to assess for superiority of one treatment to the other. This assessment measures depression severity at baseline. Total scores of 5, 10, 15, and 20 represent markers for mild, moderate, moderately severe, and severe depression, respectively. All 9 items are summed to compute a total score, ranging from 0-27. Higher scores indicate more severe self-rated depressive symptoms. Negative change from baseline implies a decrease in depressive symptoms.

5.5cm Rule Group
rTMS will be targeted at a left prefrontal target 5.5cm anterior to the primary motor strip identified on the scalp during motor threshold testing. Repetitive transcranial magnetic stimulation: Repetitive transcranial magnetic stimulation will be targeted to a location in the left prefrontal cortex and delivered according to FDA-approved parameters for the treatment of major depressive disorder, specifically high-frequency 10 Hz rTMS for 3000 pulses, 5 days per week for a total number of sessions as deemed clinically appropriate by the patient's clinical TMS treatment team but usually on the order of 20-30 treatments.
F3 Group
rTMS will be targeted at the left prefrontal scalp target identified as F3 according to the 10-20 EEG system. Repetitive transcranial magnetic stimulation: Repetitive transcranial magnetic stimulation will be targeted to a location in the left prefrontal cortex and delivered according to FDA-approved parameters for the treatment of major depressive disorder, specifically high-frequency 10 Hz rTMS for 3000 pulses, 5 days per week for a total number of sessions as deemed clinically appropriate by the patient's clinical TMS treatment team but usually on the order of 20-30 treatments.

Overall change in total Montgomery-Asberg Depression Rating Scale score from pre to post-treatment assessment, comparing results of 2 active groups to assess for superiority of one treatment to the other. This scale assesses depression severity at baseline. Scores of 8, 17, and 34 are cut-off points for mild, moderate, severe depression, respectively. This 10 item scale is summed to compute a total score, ranging from 0-60. Higher scores indicate more severe clinician-rated depressive symptoms.

Change in Montreal Cognitive Assessment scores from baseline to final timepoint. Reported here as the mean difference in total Montreal Cognitive Assessment score from baseline to endpoint. Montreal Cognitive Assessment is used a screen for cognitive impairment, calculated by adding the points from each task, which range from 0-30. Higher scores indicate little to no cognitive impairment 26 or above: Normal cognition 18-25: Mild cognitive impairment 10-17: Moderate cognitive impairment Fewer than 10: Severe cognitive impairment

T Score Changes in National Institutes of Health Toolbox Emotional Battery A T score of 50 corresponds to the population mean. Scores may range from 20-80 with a standard deviation of 10. Higher T scores indicate a higher endorsement of each domain. Here, we present changes in mean score from pre-treatment to post-treatment. In that way, a positive value represents a decrease in average T score, and vice versa.

POST_HOC outcome

Timeframe: Baseline to Weeks 1 through 6, assessed weekly

Population: All randomized participants were included in this analysis. Weekly timepoints have different ns due to dropouts and/or missing data.

An exploratory analysis to investigate between-group differences in trajectory of improvement as measured by group by time interactions. This assessment measures depression severity at baseline. Total scores of 5, 10, 15, and 20 represent markers for mild, moderate, moderately severe, and severe depression, respectively. All 9 items are summed to compute a total score, ranging from 0-27. Higher scores indicate more severe self-rated depressive symptoms. Negative change from baseline implies a decrease in depressive symptoms.

POST_HOC outcome

Timeframe: Baseline to biweekly timepoints

Population: All randomized participants were included in this analysis. Weekly timepoints have different ns due to dropouts and/or missing data.

An exploratory analysis to investigate between-group differences in trajectory of improvement as measured by group by time interactions. This scale assesses depression severity at baseline. Scores of 8, 17, and 34 are cut-off points for mild, moderate, severe depression, respectively. This 10 item scale is summed to compute a total score, ranging from 0-60. Higher scores indicate more severe clinician-rated depressive symptoms. Negative change from baseline implies a decrease in depressive symptoms.

Measure
5.5cm Rule Group
n=42 Participants
rTMS will be targeted at a left prefrontal target 5.5cm anterior to the primary motor strip identified on the scalp during motor threshold testing. Repetitive transcranial magnetic stimulation: Repetitive transcranial magnetic stimulation will be targeted to a location in the left prefrontal cortex and delivered according to FDA-approved parameters for the treatment of major depressive disorder, specifically high-frequency 10 Hz rTMS for 3000 pulses, 5 days per week for a total number of sessions as deemed clinically appropriate by the patient's clinical TMS treatment team but usually on the order of 20-30 treatments.
F3 Group
n=57 Participants
rTMS will be targeted at the left prefrontal scalp target identified as F3 according to the 10-20 EEG system. Repetitive transcranial magnetic stimulation: Repetitive transcranial magnetic stimulation will be targeted to a location in the left prefrontal cortex and delivered according to FDA-approved parameters for the treatment of major depressive disorder, specifically high-frequency 10 Hz rTMS for 3000 pulses, 5 days per week for a total number of sessions as deemed clinically appropriate by the patient's clinical TMS treatment team but usually on the order of 20-30 treatments.

POST_HOC outcome

Timeframe: Baseline to weekly timepoints

Population: All randomized participants were included in this analysis. Weekly timepoints have different ns due to dropouts and/or missing data.

An exploratory analysis to investigate between-group differences in trajectory of improvement as measured by group by time interactions. This assesses anxiety severity as baseline. Scores of 5, 10, and 15 are cut-off points for mild, moderate, and severe anxiety, respectively. All 7 items are summed to compute a total score, ranging from 0-21. Higher scores indicate more severe self-rated anxiety symptoms. Negative change from baseline implies a decrease in anxiety symptoms.
