MindMed Announces Constructive End-of-Phase 2 Meeting with U.S. FDA for MM120 in Generalized Anxiety Disorder (GAD)

-Aligned on requirements for Phase 3 clinical development of MM120 for the treatment of GAD-

-Initiation of Phase 3 program remains on schedule to begin in second half of 2024-

NEW YORK, June 20, 2024 – Mind Medicine (MindMed) Inc. (NASDAQ: MNMD) (the “Company” or “MindMed”), a clinical stage biopharmaceutical company developing novel product candidates to treat brain health disorders, today announced the completion of the End-of-Phase 2 (EOP2) meeting with the U.S. Food and Drug Administration (FDA), supporting the advancement of MM120 (lysergic acid diethylamide [LSD] D-tartrate) into pivotal trials for the treatment of adults with GAD.

“Following a constructive End-of-Phase 2 meeting with the FDA, we are pleased to have reached alignment on our Phase 3 development strategy for MM120 in GAD,” said Rob Barrow, Chief Executive Officer of MindMed. “This marks a significant milestone for MindMed and for the millions of individuals affected by GAD. We are on schedule to initiate our Phase 3 clinical program for MM120 oral dissolving tablet (ODT) in GAD in the second half of this year and look forward to sharing additional details on the design of our pivotal program in the coming months.”

The EOP2 meeting was supported by results from MindMed’s completed Phase 2b clinical trial, MMED008. The multi-center, randomized, double-blind, parallel-group, dose-finding study was designed to assess the effect of four doses of MM120 for the treatment of anxiety symptoms in participants diagnosed with GAD. In the trial, MM120 met its primary and key secondary endpoints and demonstrated a rapid, clinically meaningful, and statistically significant improvements on the Hamilton Anxiety rating scale (HAM-A) at Week 4 and Week 12, with a 65% clinical response rate and 48% clinical remission rate sustained to Week 12 in the MM120 100 µg cohort. MM120 was generally well-tolerated in this trial, with most adverse events rated as mild to moderate, transient, and occurring on the dosing day and being consistent with the expected acute effects of the trial drug.

“On behalf of the 20 million people in the U.S. – and millions more worldwide – who are living with GAD, we are incredibly excited for the therapeutic potential that MM120 shows based on the data from the previously completed Phase 2b MMED008 trial,” said Daniel R. Karlin, MD, MA, Chief Medical Officer of MindMed. “Few treatment options have shown robust activity in GAD, with the last new FDA approval occurring in 2007. We are committed to bringing MM120 to people living with GAD and are excited to move into the next phase of our development program.”

About MM120

LSD (lysergide) is a synthetic ergotamine belonging to the group of classic, or serotonergic, psychedelics, which acts as a partial agonist at human serotonin-2A (5-hydroxytryptamine-2A [5-HT2A]) receptors. MindMed is developing MM120, the tartrate salt form of lysergide, for GAD and is exploring its potential applications in other serious brain health disorders.

About Generalized Anxiety Disorder (GAD)

GAD is a common condition associated with significant impairment that adversely affects millions of people. GAD results in fear, persistent anxiety, and a constant feeling of being overwhelmed. It is characterized by excessive, persistent, and unrealistic worry about everyday things. Approximately 10%

of U.S. adults, representing around 20 million people, currently suffer from GAD. This underdiagnosed and underserved indication is associated with significant impairment, less accomplishment at work and reduced labor force participation. Despite the significant personal and societal burden of GAD, there has been little innovation in the treatment of GAD in the past several decades, with the last new drug approval occurring in 2007.
