Context-Guided Personalized iTBS for Depression

3. srpna 2026 aktualizováno: Zhi Yang, Capital Medical University

Research on Intelligent Optimization of Neuromodulation for Depression Based on Contextual Neuroimaging

The goal of this randomized clinical trial is to learn whether context-guided personalized intermittent theta burst stimulation (iTBS) works better than standard iTBS for adults with major depressive disorder. iTBS is a noninvasive treatment that uses magnetic pulses to stimulate specific areas of the brain.

Participants will be assigned by chance to one of two treatment groups. The standard treatment group will receive iTBS at a commonly used target in the left dorsolateral prefrontal cortex after watching a neutral video. The personalized treatment group will receive iTBS at an individual brain target selected using magnetic resonance imaging data. Before each treatment session, participants in this group will watch a positive emotional video intended to activate brain functions related to the selected target.

Both groups will receive five iTBS sessions per day for five consecutive treatment days. Participants will continue their stable antidepressant treatment during the study.

The main question is whether context-guided personalized iTBS results in a higher treatment response rate than standard iTBS two weeks after treatment. Treatment response is defined as a reduction of at least 50% from baseline in the 17-item Hamilton Depression Rating Scale score.

Researchers will also compare early changes in depression, anxiety and other clinical symptoms, changes in brain imaging measures, and any side effects. Clinical and brain imaging assessments will be conducted before and after the treatment course, and clinical symptoms will be assessed again two weeks after treatment.

Intervence / Léčba
Experimentální: Context-Guided Personalized iTBS
Participants assigned to this arm will receive context-guided personalized intermittent theta burst stimulation (iTBS). An individualized stimulation target in the left or right dorsolateral prefrontal cortex will be selected based on the participant's functional magnetic resonance imaging data. Before each iTBS session, participants will watch a positive emotional video intended to engage the brain functions related to the individualized target. Participants will receive five iTBS sessions per day, with approximately 50 minutes between sessions, for five consecutive treatment days. Each session will last approximately 10 minutes and deliver 1,800 pulses at 100% of the resting motor threshold.

Popis opatření
Časové okno
Treatment Response Rate at 2-Week Follow-up Based on HAMD-17
Časové okno: At 2 weeks after completion of treatment (Day 21 ± 2 days).
The treatment response rate is defined as the proportion of participants with a reduction of at least 50% from baseline in the total score of the 17-item Hamilton Depression Rating Scale (HAMD-17) at the 2-week follow-up. The HAMD-17 is a clinician-rated scale used to assess the severity of depressive symptoms, with lower scores indicating fewer depressive symptoms. Treatment response rates will be compared between the context-guided personalized iTBS arm and the standard left DLPFC iTBS arm. The HAMD-17 total score ranges from 0 to 52, with higher scores indicating greater depressive symptom severity. Change from baseline is calculated as the post-baseline score minus the baseline score, with negative values indicating improvement.
At 2 weeks after completion of treatment (Day 21 ± 2 days).

Incidence of Adverse Events
Časové okno: From the first treatment session through the 2-week follow-up after completion of treatment
The number and proportion of participants experiencing one or more adverse events will be recorded for each treatment arm. Adverse events may include headache, scalp discomfort, muscle twitching, transient mood changes, or other adverse events occurring during the treatment and follow-up periods.
From the first treatment session through the 2-week follow-up after completion of treatment
Early Treatment Response Rate Based on HAMD-17
Časové okno: Baseline to immediately after completion of the treatment intervention
Early treatment response is defined as a reduction of at least 20% from baseline in the total score of the 17-item Hamilton Depression Rating Scale (HAMD-17) immediately after completion of the treatment intervention. The outcome will be summarized as the proportion of participants meeting this response criterion in each treatment arm. Lower HAMD-17 scores indicate fewer depressive symptoms. The HAMD-17 total score ranges from 0 to 52, with higher scores indicating greater depressive symptom severity. Change from baseline is calculated as the post-baseline score minus the baseline score, with negative values indicating improvement.
Baseline to immediately after completion of the treatment intervention
Change From Baseline in HAMD-17 Factor Scores
Časové okno: Baseline, immediately after completion of treatment, and 2 weeks after completion of treatment
Changes from baseline in the prespecified factor scores of the 17-item Hamilton Depression Rating Scale (HAMD-17) will be assessed at the 2-week follow-up. For each factor, the change score will be calculated as the follow-up score minus the baseline score. A greater reduction indicates greater improvement in the corresponding depressive symptom domain. The HAMD-17 consists of 17 items; 9 items are scored from 0 to 4 and 8 items are scored from 0 to 2. The total score ranges from 0 to 52, with higher scores indicating greater depressive symptom severity. Change is calculated as the post-baseline score minus the baseline score; negative values indicate improvement.
Baseline, immediately after completion of treatment, and 2 weeks after completion of treatment

Časové okno: Baseline, immediately after completion of treatment, and 2 weeks after completion of treatment
Changes from baseline in the total score of the 16-item Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR16) will be assessed immediately after completion of the treatment intervention and at the 2-week follow-up. Lower scores indicate fewer self-reported depressive symptoms. The QIDS-SR16 total score ranges from 0 to 27, with higher scores indicating greater depressive symptom severity.
Baseline, immediately after completion of treatment, and 2 weeks after completion of treatment
Change From Baseline in HAMA Total Score
Časové okno: Baseline, immediately after completion of treatment, and 2 weeks after completion of treatment
Changes from baseline in the total score of the Hamilton Anxiety Rating Scale (HAMA) will be assessed immediately after completion of the treatment intervention and at the 2-week follow-up. The HAMA is a clinician-rated measure of anxiety symptom severity, with lower scores indicating fewer anxiety symptoms. The 14-item HAMA total score ranges from 0 to 56, with higher scores indicating greater anxiety symptom severity.
