About this trial
The goal of this clinical trial is to learn if MLS101 (psilocybin) is a possible treatment for women with Premenstrual Dysphoric Disorder (PMDD). The main question it aims to answer is:
• Test the safety and tolerability of the study drug, MLS101 in premenopausal women (ages 18-50 inclusive) with PMDD.

Menstrual cycle duration of 24-35 days (inclusive) reported at Screening
Disqualifiers
Currently meets DSM-5 criteria for MDD, GAD, Panic Disorder, OCD, Anorexia, Bulimia, Binge Eating Disorder, Borderline Personality Disorder, or Anti-Social Personality Disorder, based on M.I.N.I.

Treatment groups
Trial outcomes
Primary outcomes
Number of participants with treatment-related adverse events as assessed by CTCAE v6.0
Safety and tolerability of MLS101 and placebo from baseline through Visit 11/Final Telehealth Visit (Day 44 ± 5) as assessed by type, frequency, severity, timing, and relationship to MLS101 of any adverse events (AEs), adverse events of special interest (AESIs) serious adverse events (SAEs)
Secondary outcomes
No change from baseline to end of study in mitral valve leaflet thickness as measured by transthoracic echocardiogram
Baseline transthoracic echocardiogram to measure mitral valve leaflet thickness. Mitral valve leaflet thickness of \< 3 mm is normal, whereas \>3 mm in mitral valve leaflet thickness is considered abnormal in an echocardiogram.
Change in Maximum Plasma Concentreation (Cmax)
Blood samples will be collected at 30 minutes, and 1, 2, 3, 4, 6, and 8 hours after a single dose of study drug to determine the change in Cmax
Change in subjective psychedelic experience from pretreatment to 8 hours after treatment
The Acute Subjective Effects Scale (ASES) is a visual analog scale from 0-10 with 0 being no psychedelic experience and 10 being the most intense. Participants will have to score less than or equal to 2 to be considered recovered from treatment effects.
Participant reported drug liking
Drug liking will be assessed using the drug Liking Visual Analog Scale (VAS) which is a scale from 0 which indicates strong dislike to 100 which indicates strong liking and a score of 50 is neutral.
