Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Remission
Clinical outcome is remission, which is defined as a score of 7 or lower on the clinician-rated HDRS-17 (17-itemHamilton Depression Rating Scale, scores 0-52 with higher score indicating worse outcome) measured one week after the last treatment session.
After 1 week.
Secondary Outcomes (5)
Health-related quality of life
After 1-, 5-, 10- and 25-weeks.
Self-rated depressive symptoms
After 1-, 5-, 10- and 25-weeks.
Relapse
After1-, 5-, 10- and 25-weeks.
Side-effects
After 1- and 6- weeks.
Remission
5-, 10- and 25-weeks after the last treatment session.

Eligibility Criteria
You may qualify if:
- years of age or older;
- Sufficient level of spoken and written Dutch;
- 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.
You may not qualify if:
- \- Bipolar disorder.
- Current psychotic disorder¸ including psychotic depression, assessed by treating psychiatrist.
- Active suicidal thoughts and intent to act on it, assessed at the baseline interview and before the start of the trial. This assessment is based on the Columbia suicide severity rating scale, i.e., question 5 is answered positive "Have you started to work out or worked out the details of how to kill yourself? Do you intend to carry out this plan?" (26).
- Metallic devices implanted above the neck, assessed at the baseline interview.
- Patients diagnosed with epilepsy, by a neurologist, assessed at the baseline interview.
- Substance abuse 4 weeks prior to the study, including high dosage of benzodiazepine, a dosage equivalent higher than 3.0 mg lorazepam, assessed at the baseline interview.
- Inability to understand or comply with study requirements as judged by the investigators, assessed at the baseline interview.
- Pregnancy
