Outcome Measures
Primary Outcomes (4)
Montgomery Asberg Depression Rating Scale (MADRS)
A ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Scoring ranging from 0 to 60, with higher scores indicating greater depressive symptomology.
12 months
fMRI task-evoked brain activation
A method used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which are found to be active at any given time.
At both 1 week and 2 weeks
fMRI resting state
A method aimed at examining intrinsic networks in the brain while no task is performed (rest) in order to estimate correlations between brain regions.
At both 1 week and 2 weeks
EEG functional connectivity change
A method aimed at examining intrinsic networks in the brain to estimate correlations between brain regions.
At both 1 week and 2 weeks
Secondary Outcomes (21)

Study Arms (4)
Full dose COMP360 with active aiTBS rTMS
EXPERIMENTAL25mg of COMP360 with the active accelerated intermittent theta burst (aiTBS) rTMS treatment known as Stanford Neuromodulation Therapy (SNT) and/or Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT) delivered over 10 sessions daily for 5 consecutive days.
Full dose COMP360 with sham aiTBS rTMS
ACTIVE COMPARATOR25mg of COMP360 with sham iTBS delivered over 10 sessions daily for 5 consecutive days.
Low dose comparator with active aiTBS rTMS
ACTIVE COMPARATOR1mg of COMP360 with the active accelerated intermittent theta burst (aiTBS) rTMS treatment known as Stanford Neuromodulation Therapy (SNT) and/or Stanford Accelerated Intelligent Neuromodulation Therapy (SAINT) delivered over 10 sessions daily for 5 consecutive days.
Low dose comparator with sham aiTBS rTMS
SHAM COMPARATOR1mg of COMP360 with with sham iTBS delivered over 10 sessions daily for 5 consecutive days.
Interventions
A psychedelic drug found in certain mushrooms. It will be in a capsule of 25mg psilocybin (COMP360).
A form of non-invasive brain stimulation that delivers a series of quick magnetic pulses to the scalp and a portion of the brain. It will be targeted to a functional magnetic resonance imaging (fMRI) functional connectivity-guided personalized left dorsolateral prefrontal cortex target using neuronavigation and delivered over 10 sessions daily for 5 consecutive days at 90% of coil-to-target depth-corrected resting motor threshold.
A psychedelic drug found in certain mushrooms. It will be in a low-dose form of the experimental dose as a 1mg capsule of psilocybin (COMP360).
The sham version is meant to look and feel like the active SAINT rTMS, but the main difference is that the brain is not being stimulated like the active condition.
Eligibility Criteria
You may qualify if:
- Adults, ages 22-65.
- English language comprehension suitable to understand experimenter instructions and to communicate to study personnel/staff reasonably easily.
- Current major depressive episode (without psychotic features), either as part of recurrent major depressive disorder (MDD) or single episode MDD with current episode present for at least the past 3 months (as determined by the Structured Clinical Interview for DSM-5; SCID-5).
- Montgomery Asberg Depression Rating Scale (MADRS) score of 20 or greater at baseline assessment (at least moderate severity).
- \. Treatment-resistant MDD, defined as either: a) failure to respond to an adequate dose and duration of two or more pharmacological treatments, with at least one failed medication trial occurring in the current major depressive episode; or b) failure to respond to an adequate dose and duration of 2 or more pharmacological treatments of different pharmacological classes in one or more past major depressive episodes. Adequate treatment dose and duration will be determined through the Massachusetts General Hospital Antidepressant Treatment Response Questionnaire (MGH-ATRQ). Augmentation, where an add-on medication is used, will be counted as a second treatment, provided it is approved as an adjunctive treatment of MDD in the country where prescribed.
- Willingness and ability to attend daily, full-day visits to the research site for a period of \~2 weeks and to participate in all study procedures (clinical assessments, treatments, and neurobiological assessments).
- If currently taking an antidepressant medication (an SSRI, SNRI, or atypical antidepressant), antipsychotic, and/or other augmenting medication (e.g., lithium), willingness to discontinue medication(s) over a 2-8 week period with the assistance of study staff and maintain at least a 2-5 week period (5-week period for fluoxetine) off of medications prior to the baseline visit AND willingness to remain off medications for a period of 1 month following the end of the treatment course (approximately 6-8 weeks after the baseline visit).
You may not qualify if:
- Prior history or current diagnosis of a psychotic disorder (including MDD with psychotic features), bipolar disorder, or personality disorder (based on medical history, clinician judgement, SCID-5 and/or SCID for Personality Disorders).
- Current diagnosis of posttraumatic stress disorder, acute stress disorder, obsessive-compulsive disorder, anorexia nervosa, bulimia nervosa, or alcohol or substance-use disorder.
- Having met criteria for an alcohol or substance-use disorder within the past year.
- Use of electroconvulsive therapy, deep brain stimulation, or vagus nerve stimulation during the current major depressive episode.
- Any prior rTMS treatment (10Hz, 5Hz, 1Hz, or conventional intermittent theta burst).
- Current participation in an evidence-based psychotherapy for major depression (e.g., cognitive behavioral therapy, behavioral activation). Ongoing supportive psychotherapy is allowable if maintained at the same frequency throughout the duration of the short-term follow-up clinical endpoint (1 month after treatment cessation) of the study and if no recent change in therapy type or frequency for 1 month prior to enrollment.
- Exhibiting significant suicide risk within the past 12 months, at screening, or at baseline, as evidenced by: a) suicidal ideation with some intent to act but no specific plan (item #4 from the Columbia Suicide Severity Rating Scale57; C-SSRS); b) suicidal ideation with intent to act and a specific plan (item #5 from the C-SSRS); c) suicide attempt or non-suicidal self-injury requiring medical attention in the past 12 months; or d) self-report of significant suicidal ideation with intent or significant non-suicidal self-injury during screening or baseline clinical interview.
- Major depressive episode that is secondary to a medication or a general medical condition, as judged by investigators.
- Any other factors, such as major medical conditions, unstable housing or threatening life circumstances, erratic behavior, etc. that are judged by the investigators to be a significant barrier to participation in the study protocol and/or to establishing therapeutic rapport necessary for safe administration of psilocybin.
- Prior past-year ingestion of a serotonergic psychedelic, e.g., psilocybin, LSD, mescaline, dimethyltryptamine, etc. or more than 5 lifetime ingestions of a serotonergic psychedelic on separate occasions.
- Participant unwillingness to not ingest or use additional serotonergic psychedelics outside the context of study procedures for the duration of the study follow-up period (12 months).
- Ferrous metal, metallic implants, or implanted medical devices that would preclude administration of rTMS and/or participation in MRI procedures, including but not limited to: cochlear implants, implanted brain stimulators, aneurysm clips.
- Past history of seizures or epilepsy (rTMS risk).
- Neurological disorder, including epilepsy, stroke, or history of brain surgery.
- Past penetrating brain injury or any head injury resulting in a loss of consciousness for 30 minutes or more or post-concussive symptoms for more than seven days following a head injury.

Data Sharing
- IPD Sharing
- Will not share
If participants chose to, they can be included in the Department of Psychiatry's Registry (Protocol 2020-04-0046). Participants may elect to be part of this registry, but this is not required as part of the participation in the current study. No other plans for sharing data outside of a research related inquiry for research purposes is expected. The registry informed consent will be provided to the participant if interested and consent will be obtained per procedures outlined in the registry protocol. De-identified data may be shared with future researchers for scientific purposes. If our lab shares biospecimens with future researchers, it will only be de-identified data. In this case, it will be shared in the form of an aggregated database with no PHI or PII included.
