Neurotransmitters and Hormones • Monoamine release and reuptake inhibition • Serotonin (5-HT) • Norepinephrine (NE) • Dopamine (DA) • Greatest effects are on serotonin release • Elevates plasma concentrations of a number of hormones: • Oxytocin • Vasopressin • Cortisol • Prolactin • Dehydroepiandrosterone (DHEA) • Adrenocorticotropic hormone (ACTH) • Wolff, et al.

“Before, I knew the path was through a battlefield, but I could not get through it. During MDMA therapy, I knew I could walk through it and I wasn’t afraid. MDMA gave me the ability not to fear.” Donna, a patient in the US pilot study 6
Positive Safety Profile • Phase 1 & Phase 2 clinical trials > 800 people • No unexpected unexpected drug-related serious adverse events in medical research settings using pure MDMA • Adverse Events are generally mild to moderate and self limited • Neurocognitive function –RBANS and PASAT • No change pre and post MDMA or placebo • Changes in Vital signs during sessions similar between MDMA and Placebo Group 7
More common with MDMA: Decreased concentration Jaw Clenching Dizziness Dry mouth Feeling cold Impaired Balance Anxiety Common Side Effects More common with inactive placebo: • Anxiety • Drowsiness • Insomnia Jerome L.

Toxicity in Recreational Users • Rare cases of Serious acute toxicity in recreational users • Neurotoxicity in animals at high, repeated IV doses, not relevant to doses used in human studies • PET scans- no change in estimated serotonin transporter binding sites 4 weeks after a clinically relevant dose of MDMA • Moderate abuse potential • Jerome L.

Benefits of MDMA • Enhances psychotherapy, not taken as ongoing medication • Desirable effects on brain activity, neurochemistry and hormones • Positive Risk/Benefit Ratio • Attenuates the fear response and decreases defensiveness without blocking access to memories while encouraging a deep and genuine experience of emotion (Metzner et al. 1988). 10

“After the MDMA took effect, my soul sparked back to life. I felt connected to a vibrant life force, and I awakened to a childlike curiosity and inner power. I learned that I shape my reality and control my destiny with how I perceive and how I act. Now I feel that my true strength is facing my weaknesses and fears, and moving on from there. I am not perfect, but I have learned a lot about myself. If something gets the fear going, I can see it as something I can learn from.” 16
