This study is an open-label, single-arm, within-subjects design in individuals with mild-moderate Major Depressive Disorder (MDD). All participants will receive a single dose of 25mg of psilocybin in a therapeutic setting. In order to investigate the effects of length of time on SSRI therapy, 30 participants with varying lengths of time on SSRI therapy will be enrolled, stratified into four groups: - Group 1: ≤ 1 year - Group 2: 1 to ≤ 5 years - Group 3: 5 to ≤ 10 years - Group 4: > 10 years

Any other clinically significant cardiovascular, pulmonary, gastrointestinal, hepatic, renal, vascular or any other major concurrent illness that, in the opinion of the Investigator, may interfere with the interpretation of the study results or constitute a health risk for the participant if he/she takes part in the study 10. Cardiovascular conditions: coronary artery disease, stroke, angina, uncontrolled hypertension, a clinically significant ECG abnormality (e.g., atrial fibrillation), prolonged QTc interval (i.e., QTc > 450msec), artificial heart valve, or TIA in the past year 11. Psychoactive substance use within the previous two months. 11a. The following criteria are preferred: lifetime total psychoactive substance use less than 10 times. 12.

Primary | Quick Inventory of Depressive Symptomatology-Self-Report (QIDS-SR-16) | The QIDS-SR16 is a 16-item self-reported rating scale designed to assess severity of depressive symptoms. Scores range from 0 to 27, with higher scores indicating greater depression. | Baseline to end of study (week 12) | |
Secondary | QIDS-SR-16 response | Defined as a reduction in score of >50%. The QIDS-SR16 is a 16-item self-reported rating scale designed to assess severity of depressive symptoms. Scores range from 0 to 27, with higher scores indicating greater depression. | Baseline to end of study (week 12) | |
Secondary | QIDS-SR-16 remission | Defined as a score of =5. The QIDS-SR16 is a 16-item self-reported rating scale designed to assess severity of depressive symptoms. Scores range from 0 to 27, with higher scores indicating greater depression. | Baseline to end of study (week 12) | |
Secondary | Montgomery and Asberg Depression Rating Scale (MADRS) | A clinician-rated interview to assess the severity of depression. Each item has a severity scale from 0 to 6, with higher scores reflecting more severe symptoms. Ratings can be added to form an overall score (from 0 to 60). | Baseline to end of study (week 12) | |
