入选标准
- •Adults ≥ 21 years of age at Screening
- •Diagnosis of Major Depressive Disorder (MDD)
- •Score of at least 12 (symptomatic depression) on administration of the Montgomery Asberg Depression Rating Scale (MADRS)
- •Score of at least a 3 on question 8 on the MADRS evaluating loss of interest and ability to feel at both Screening and Baseline Visit 1
- •The participant's Major depressive disorder meets the criteria for being treatment-resistant, defined as not experiencing a 50% improvement to two or more antidepressant treatments for adequate duration (6 weeks minimum) within the current episode, as determined by the Antidepressant Treatment Response Questionnaire (Desseilles et al., 2011; Posternak et al., 2004)

A person of childbearing potential is anyone born female who has experienced menarche and who has not undergone surgical sterilization (eg, hysterectomy, bilateral salpingectomy, bilateral oophorectomy) or has not completed menopause. Menopause is defined clinically as 12 months of amenorrhea in a person over age 45 in the absence of other biological, physiological, or pharmacological causes.

- •Ability to abstain from caffeine and nicotine for 2 hours prior to fMRI scan visits
排除标准
- •Unstable medical conditions or serious abnormalities of complete blood count, chemistries, or EKG that in the opinion of the study physician would preclude safe participation in the trial. Some examples include:
- •Congestive heart failure
- •Clinically significant arrhythmias (e.g. ventricular fibrillation, torsades) or clinically significant EKG abnormality (i.e. QTC interval > 450)
- •Recent acute myocardial infarction or evidence of ischemia
- •Malignant hypertension
- •Congenital long QT syndrome
- •Acute renal failure
- •Severe hepatic impairment
- •Respiratory failure
- •Risk for hypertensive crisis defined as Screening, Baseline, and Medication Session (prior to dosing) Blood Pressure >140/90 mmHg.
- •High resting heart rate defined as Screening, Baseline, and Medication Session (prior to dosing) heart of rate of >90 BPM
- •Significant CNS pathology as determined by self-report and confirmed by a history and physical examination and review of medical records. Current and historical psychiatric disorders will be determined by the MINI. Specific examples include:
- •Primary or secondary cerebral neoplasm
- •History of stroke
- •Cerebral aneurysm
- •h. Current or lifetime primary psychotic disorder, bipolar affective disorder, affective disorder with psychotic features. Some examples include: i. Schizophrenia spectrum disorders j. Schizoaffective disorder k. Bipolar I or Bipolar II disorder l. History of mania m. Major depressive disorder with psychotic features
- •Family history of first-degree relative with psychotic or serious bipolar spectrum illnesses. Examples include first-degree relative with:
- •Schizophrenia spectrum disorders
- •Schizoaffective disorder
- •Bipolar I disorder with psychotic features
- •High risk of adverse emotional or behavioral reaction based on investigator's clinical evaluation. Examples include:
- •Violent behavior
- •Active SUDs evaluated by the MINI and defined as: DSM-5 criteria for moderate or severe alcohol or drug use disorder (excluding caffeine and nicotine) within the past year
- •Extensive use of serotonergic hallucinogens (e.g. LSD, psilocybin) defined as:
- •Any use in the last 6 months
- •>25 lifetime uses

- •History of severe suicide attempt requiring hospitalization in the past year
- •Have any suicidal ideation or thoughts, in the opinion of the study physician or PI, that presents a serious risk of imminent suicidal or self-injurious behavior
- •Use of drugs or dietary supplements that per the discretion of the study team, have a mechanism of action that would interfere with procedures of study or have an adverse interaction with the study drug. Examples include direct agonists/antagonists of serotonin receptors such as those listed below. Selective Serotonin Re-uptake Inhibitors and Serotonin Norepinephrine Re-uptake Inhibitors are allowed at the discretion of the PI. Individuals need to be off all non-allowed drugs for a period of 5 half-lives prior to the baseline visit.
- •Antipsychotics
- •Cyproheptadine
- •Mirtazapine
- •Flibanserin
- •Tricyclic antidepressants
- •Monoamine oxidase inhibitors
- •Serotonergic dietary supplements including St. John's Wort, L-tryptophan and 5-Hydroxytryptophan (5-HTP)
- •Psychiatric condition judged to be incompatible with establishment of rapport with therapy team and/or safe exposure to psilocybin based on investigator's clinical evaluation
- •Have an allergy or intolerance to any of the materials contained in either drug product

- Change from baseline in self-reported anhedonia scores on the Snaith-Hamilton Pleasure Scale (SHAPS).(One week and eight weeks post-dosing)
- Change from baseline in response bias for the high reward condition on the Probabilistic Reward Task (PRT)(One and eight weeks post-dosing)
- Change from baseline in nucleus accumbens neural activation during expectation of reward versus expectation of non-reward during the Monetary Incentive Delay Task (MID).(One week post-dosing)
- Change from baseline in depression scores as measured by self-report on the Quick Inventory of Depressive Symptomatology (QIDS-SR-16).(One, four, and eight weeks post-dosing)
