Mind Medicine (MindMed) Inc. (NASDAQ: MNMD), (NEO: MMED) (the "Company" or "MindMed"), a clinical stage biopharmaceutical company developing novel products to treat brain health disorders, today announced first patient dosing in its Phase 2b dose-optimization trial of MM-120, a pharmaceutically optimized form of lysergic acid diethylamide (LSD), for the treatment of Generalized Anxiety Disorder (GAD).

"The initiation of our Phase 2b clinical trial, the largest well-controlled clinical trial of LSD ever conducted, represents a major milestone for MindMed and for the many patients suffering from GAD," said Robert Barrow, Chief Executive Officer and Director of MindMed. "This exciting next step in the advancement of LSD builds on the positive topline data presented by our partners at University Hospital Basel in May 2022, which demonstrated the rapid, durable, and statistically significant effects of LSD and its potential to safely mitigate symptoms of anxiety and depression. The results of our Phase 2b trial will guide the dose selection and development strategy for our pivotal Phase 3 clinical trials, as we continue our efforts to bring a new potential treatment to the millions of people living with GAD."

The Phase 2b trial in patients diagnosed with GAD is a multi-center, parallel, randomized, double-blind, placebo-controlled, dose-optimization study. The trial plans to enroll 200 participants who will receive a single administration of up to 200 µg of MM-120 or placebo. The primary objective is to determine the reduction in anxiety symptoms 4 weeks after a single administration of MM-120, compared across the five treatment arms. Key secondary objectives, measured up to 12 weeks after the single administration, include assessments of safety and tolerability as well as quality of life. More information about the trial is available on our website (mindmed.co) or on clinicaltrials.gov (identifier NCT05407064).

About Generalized Anxiety Disorder (GAD)

GAD is a chronic, often debilitating mental health disorder that affects approximately 6% of U.S. adults in their lifetimes. Symptoms of GAD include excessive anxiety and worry that persists for over six months, which can lead to significant impairments in social, occupational and other functioning, according to the National Institute of Mental Health (NIMH). While there is substantial diagnostic overlap between GAD, Major Depressive Disorder (MDD) and other major mental health disorders, there has been very little innovation focused on the treatment of GAD in the past several decades.
