Mind Medicine (MindMed) Inc. (NASDAQ: MNMD), (the "Company" or "MindMed"), a late-stage clinical biopharmaceutical company developing novel product candidates to treat brain health disorders, today reported financial results for the third quarter ended September 30, 2025 and provided business updates.

“2025 continues to be a year of strong execution, and our recent $258.9 million financing further strengthens our position as we prepare for a transformational 2026,” said Rob Barrow, Chief Executive Officer of MindMed. “Enrollment across all three pivotal MM120 ODT trials remains on track. Given faster than expected enrollment in Emerge, our first Phase 3 study in MDD, we have accelerated guidance for topline data readout which is now expected in mid-2026. We plan to initiate Ascend, our second Phase 3 study in MDD, in mid-2026 and remain focused on advancing toward FDA submissions in both generalized anxiety disorder (GAD) and major depressive disorder (MDD). We are also excited to advance our pipeline with the start of a Phase 2a study of MM402 in ASD. With multiple anticipated Phase 3 topline data readouts ahead, 2026 is set to be the most significant year in our history to date, as our team works to bring new treatment options to both providers and patients.”

Business Updates

• On October 31, 2025, the Company completed an underwritten public offering of 21,131,250 common shares of the Company for gross proceeds of $258.9 million. Net proceeds from the offering were approximately $242.8 million, after deducting underwriting discounts and commissions and other estimated offering expenses payable by the Company.
  
  
  
  
• The Company published full study results in JAMA from its randomized, placebo-controlled Phase 2b trial evaluating a single dose of MM120 across four dose levels in patients with moderate to severe GAD. The Phase 2b study demonstrated a statistically significant dose-response relationship at the primary endpoint following a single administration of MM120 across four dose levels, with improvements sustained throughout the 12-week observation period. MM120 100 µg was determined to be the optimal dose, meeting its primary and key secondary endpoints, demonstrating a clinically and statistically significant improvement vs. placebo, and a 65% clinical response rate and 48% clinical remission rate at Week 12. MM120 was well-tolerated with mostly mild-to-moderate adverse events that were limited to the dosing day and consistent with the mechanism of action of lysergide D-tartrate (LSD). These results represent a substantial improvement over currently approved therapies for GAD, which led to MM120 being granted Breakthrough Therapy Designation (BTD) from FDA in March 2024.

Program Status and Anticipated Milestones

MM120 ODT (lysergide D-tartrate) for GAD

• Enrollment is on track in the Phase 3 Voyage study of MM120 ODT for the treatment of GAD. Voyage is expected to enroll approximately 200 participants in the U.S. who will be randomized 1:1 to receive MM120 ODT 100 µg or placebo. Topline data from the 12-week double-blind period (Part A) is anticipated in the first half of 2026.
  
  
  
  
• Enrollment is on track in the Panorama study, the Company’s second Phase 3 study of MM120 ODT for the treatment of GAD. Panorama is expected to enroll approximately 250 participants (randomized 2:1:2 to receive MM120 ODT 100 µg, MM120 ODT 50 µg control, or placebo) in the U.S. and Europe. Topline data from the 12-week double-blind period (Part A) is anticipated in the second half of 2026.

MM120 (lysergide D-tartrate) for MDD

• Enrollment in the Phase 3 Emerge study of MM120 ODT for the treatment of MDD has progressed faster than previously expected and topline data from the 12-week double-blinded period (Part A) is now anticipated in mid-2026 (previously 2H 2026). Emerge is expected to enroll approximately 140 participants (randomized 1:1 to receive MM120 ODT 100 µg or placebo).

• The Company plans to initiate Ascend, its second Phase 3 study in MDD, in mid-2026. Similar to Emerge, Ascend will consist of two parts: Part A, a 12-week, randomized, double-blind, placebo-controlled, parallel group assessing the efficacy and safety of MM120 ODT versus placebo, and Part B, a 40-week open-label extension period. The primary endpoint will be the change from baseline in Montgomery Åsberg Depression Rating Scale (MADRS) score at Week 6 between MM120 ODT 100 µg and placebo. The trial is expected to enroll approximately 175 participants (randomized 2:1:2 to receive MM120 ODT 100 µg, MM120 ODT 50 µg control or placebo).

MM402 (R(-)-MDMA) for Autism Spectrum Disorder (ASD)

• Following the completion of its single-ascending dose Phase 1 study of MM402 in adult healthy volunteers, the Company plans to initiate a Phase 2a study in the fourth quarter of 2025. This study will be a single-dose, open-label study to assess early signals of efficacy of MM402 in treating core socialization and communication symptoms of ASD in up to 20 adult participants. The objectives and endpoints of the study are designed to characterize the pharmacodynamics and clinical effects of MM402 in adults with ASD, including on multiple functional biomarkers.

Third Quarter 2025 Financial Results

Cash, Cash Equivalents and Investments. As of September 30, 2025, MindMed had cash, cash equivalents and investments totaling $209.1 million compared to $273.7 million as of December 31, 2024. Based on the Company’s current operating plan and anticipated milestones, the Company believes that its cash, cash equivalents and investments as of September 30, 2025, along with the net proceeds of $242.8 million from the recently completed offering, will be sufficient to fund the Company’s operations into 2028.

Research and Development (R&D). R&D expenses were $31.0 million for the quarter ended September 30, 2025, compared to $17.2 million for the quarter ended September 30, 2024, an increase of $13.8 million. The increase was primarily due to increases of $11.7 million in MM120 program expenses, $2.5 million in internal personnel costs reflecting expanded research and development capabilities, and $0.2 million in preclinical and other program expenses, partially offset by a $0.6 million reduction in MM402 program expenses.

General and Administrative (G&A). G&A expenses were $14.7 million for the quarter ended September 30, 2025, compared to $7.6 million for the quarter ended September 30, 2024, an increase of $7.1 million. The increase was primarily due to increases of $3.0 million in personnel-related expenses, $2.0 million in commercial-preparedness related expenses, $1.6 million in corporate affairs expenses and $0.5 million in other miscellaneous administrative expenses.

About MM120 Orally Disintegrating Tablet (ODT)

MM120 ODT (lysergide D-tartrate or LSD) is an ergoline derivative belonging to the group of classic serotonergic psychedelics which acts as a partial agonist at specific serotonin receptors (human serotonin-2A (5-HT2A) receptors). MM120 ODT is MindMed’s proprietary and pharmaceutically optimized formulation of LSD. MM120 ODT is an advanced formulation incorporating Catalent’s Zydis® ODT fast-dissolve technology, which is designed to deliver several unique advantages, such as faster absorption and faster onset of transient cognitive, perceptual, and affective changes, improved bioavailability, and lower incidence of gastrointestinal side effects. MindMed is developing MM120, the tartrate salt form of lysergide, for generalized anxiety disorder (GAD), major depressive disorder (MDD), and is exploring its potential applications in other serious brain health disorders.

About MM402

MM402 is the Company’s proprietary form of R(-)-MDMA (rectus-3,4-methylenedioxymethamphetamine), being developed for the treatment of core symptoms of autism spectrum disorder (ASD). MDMA is a synthetic molecule that is often referred to as an empathogen because it is reported to increase feelings of connectedness and compassion. Preclinical studies of R(-)-MDMA demonstrate its acute pro-social and empathogenic effects, while its diminished dopaminergic activity suggest that it has the potential to exhibit less stimulant activity, neurotoxicity, hyperthermia and abuse liability compared to racemic MDMA or the S(+)-enantiomer.
