Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

INTRODUCTION Recent findings from three small studies (total n=59) suggest that three changes in repetitive Transcranial Magnetic Stimulation (rTMS) protocols, called the Stanford Neuromodulation Therapy (SNT) protocol, contribute to extreme high overall remission of 79% in patients with treatment resistant depression (TRD), whereas remission using a standard 10 Hz rTMS protocol is 25%. The improvement using the SNT protocol is achieved by combining 1) accelerated treatment with multiple sessions per day, 2) applying a higher overall pulse dose of stimulation, using intermittent Theta Burst Stimulation (iTBS), and 3) precise targeting of the region in the left dorsolateral prefrontal cortex (DLPFC), using functional MRI guided neuronavigation.

OBJECTIVE To determine if the SNT protocol is more (cost-) effective compared to standard 10 Hz rTMS in patients with TRD, even though the number of pulses given in both protocols is equal, i.e., 90,000.

STUDY DESIGN Multicenter randomized controlled trial comparing SNT with standard 10Hz rTMS with a follow-up of 25 weeks.

STUDY POPULATION 108 Patients with TRD (no response to 2 or more evidence-based treatments).

INTERVENTION 50 sessions using the SNT protocol in 5 days. The region of the left DLPFC most anticorrelated with the subgenual anterior cingulate cortex in each participant will be targeted based on subject-specific functional resting state MRI.

COMPARISON 30 standard daily 10 Hz rTMS sessions in six weeks, targeting the left DLPFC based on standard measurement procedures of the skull.

OUTCOME MEASURES

* Remission, based on the Hamilton depression rating scale
* Cost effectiveness, based on healthcare resource use
* Quality of life and positive mental health
* Tolerability and safety
* Relapse
* Description of opportunities and difficulties with regard to implementation

SAMPLE SIZE The investigators will enrol 108 patients (α=0.05, power is 0.80) including adjustment for attrition.

COST EFFECTIVENESS ANALYSIS SNT is faster and possibly more effective than 10Hz rTMS leading to a total cost reduction of 22 million each year considering less expensive healthcare, reduced illness duration and absence from work.

TIME SCHEDULE Within 36 months, the investigators will recruit and treat 108 patients with TRD: each center will recruit 9 patients per year. After the last follow-up assessments, the investigators will finalise the study within 12 months and report the results.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Rationale: Novel therapies are crucial for patients with unipolar depression since more than 33% of these patients are medication-resistant. As a consequence, there is a high burden of illness for patients with depression, leading to increased suicide rates, inability to maintain proper work and/or social role functions, and reduced quality of life. A promising novel treatment strategy is an intensive five-day course of intermittent Theta Burst Stimulation (iTBS), a form of transcranial magnetic stimulation (rTMS), which could lead to exceptionally high remission rates (79%) in patients with treatment resistant depression. However, it remains unclear whether this novel treatment strategy is more effective in depressed patients when compared to standard 10Hz rTMS (remission 30%).

Hypothesis: 5-day multi daily neuronavigated iTBS sessions (developed by Stanford University and coined, SNT, i.e., Stanford NeuromdulaTion protocol) are more (cost-) effective than standard 10 Hz rTMS in patients with treatment resistant depression.

Objective: To determine remission of depression and cost effectiveness using the SNT protocol, in patients with treatment resistant depression who did not respond to two or more evidence-based treatments.

Study design: This study comprises a multicentre, two-phase, randomized clinical trial. Phase 1 comprises a randomized controlled trial. In Phase 1, participants will be assigned to one of the two active treatment conditions, and will receive either treatment using the SNT protocol (5 days of 10 sessions/day, resulting in 50 sessions in total 90000 pulses) or standard 10 Hz left sided rTMS, provided once daily during 6 weeks (30 sessions in total, 90000 pulses). Phase 2 comprises three follow-up measurements, one at 5 weeks, one at 10 weeks and one at 25 weeks after the last treatment with SNT or 10 Hz standard rTMS. Finally, participants who were allocated to standard 10 Hz rTMS will be offered SNT after the end of the study (e.g., 25 weeks after the last rTMS session). Patients allocated to SNT can obtain 10 Hz standard rTMS after SNT has been completed.

Study population: Adult patients with unipolar depression who did not respond to two or more evidence-based treatments for depression, in the current depressive episode, aged 18 years and over.

Sample size: Sample size calculations based on differences in remission suggest that a well-powered trial should consist of 108 patients (for a 2-sided test at alpha=0.05 and with power=0.80).

Intervention: 50 sessions using the SNT protocol in 5 days. The subregion of the left DLPFC most anticorrelated with the subgenual anterior cingulate cortex (sgACC) in each participant will be targeted based on patient-specific functional resting state magnetic resonance imaging .

Comparison: 30 standard daily 10 Hz rTMS sessions in six weeks, targeting the left DLPFC based on standard scalp-based measurement procedures.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Ability to freely provide written informed consent;
* Current DSM-5 diagnosis of a depressive episode, ascertained by the Mini International Neuropsychiatry Interview (MINI-S).
* A Hamilton depression rating score (HDRS) of \>16 points: this score will be obtained from the SIGH-ADS, a depression rating scale able to determine the HDRS score and a score for atypical depression.
* have a treatment resistant depression, defined according to the criteria of Conway, that is, lack of remission for eight consecutive weeks after two different evidence-based treatments anti-depressant medication has to be adequately dosed(7,24).
* Stable anti-depressant medication 6 weeks prior to study. Benzodiazepines may be used up to a dosage equivalent of 3.0 mg lorazepam, and can be lowered over time during the study based on clinical judgement.

These cut-offs ensure exclusion of patients with (preclinical) dementia.
