简要总结
The goal of this clinical trial is to estimate the importance of neuroimaging in accelerated intermittent theta burst stimulation (aiTBS) for depression. Participants will receive aiTBS treatment, but they will not know if their treatment spot was found with neuroimaging or head measurements.
详细描述
Techniques for modulating human brain networks are rapidly evolving. One of the most exciting new developments is accelerated intermittent theta burst stimulation (aiTBS), a transcranial magnetic stimulation (TMS) protocol that involves multiple daily treatments rather than gold standard once daily treatment. A specific accelerated iTBS protocol called Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT) was cleared by the FDA in September 2022 based on two pilot studies in which patients with treatment-resistant depression rapidly and robustly improved with SAINT. Many of these patients had been depressed for decades and had not improved with conventional TMS or electroconvulsive therapy. Despite these promising results, two issues may limit SAINT scalability: 1) SAINT has only been tested at a single site in a small number of patients, 2) SAINT has never been tested without individualized resting state functional connectivity (rsfc) targeting, which is not widely available or covered by insurance. In this pilot trial, patients with treatment-resistant depression (n=40) will be randomized to one of two active treatment arms: 1) Real aiTBS with real individualized rsfc targeting, or 2) Real aiTBS with sham individualized rsfc targeting (i.e. conventional TMS targeting based on scalp landmarks). All patients will receive active stimulation, which will facilitate enrollment and reduce ethical concerns about placebo treatment in a vulnerable population when there is existing evidence of treatment efficacy. Patients and clinicians will be blind to group assignment, and blind integrity will be assessed. All patients will undergo MRI scans immediately before treatment and at one month follow up, which aligns with our clinical outcome measures.

盲法说明
Participants will put on a swim cap and undergo treatment site-marking according to standard protocols. All individuals will get two treatment sites marked: 1) Their individualized target based on resting state functional connectivity data, and 2) Beam F3 target based on head measurements. One group will be treated at target #1, and the other group will be treated at target #2.
Neither group will be able to see the computer screen that shows the neuronavigation in real-time, although they will be able to see their MRI scan on a monitor.

结局指标
主要结局
Montgomery-Åsberg Depression Rating Scale (MADRS)
时间窗: Baseline, one month after treatment
Depression severity rating scale (0-60, higher numbers indicate higher severity). The primary outcome measure was the baseline-adjusted MADRS score one month after treatment. The primary analysis of this primary outcome measure was the effect size of connectivity-based targeting.
Montgomery-Åsberg Depression Rating Scale (MADRS)
时间窗: one month after treatment
Depression severity rating scale (0-60, higher numbers indicate higher severity). The primary analysis of the primary outcome will be the effect size (i.e., Cohen's d) of imaging-guided accelerated TMS relative to scalp-targeted TMS. This outcome has not changed since the original grant application for this study. Actual group differences will be explored in a secondary analysis of this primary outcome measure. Note added May 2025: The description of the primary outcome measure was clarified. The primary outcome remains unchanged.
