MindMed named Brandi L. Roberts chief financial officer effective June 2, 2025, with inducement awards of an option on 500,000 shares and 125,000 performance share units. The awards sit outside the company's equity plans, and the lead drug's pivotal trials have not yet reported.
The company refinanced its K2 HealthVentures term loans with a $42.0 million first tranche, cut the interest rate and gave lenders the right to convert up to $7.0 million into shares. Up to $120.0 million is available in total, but the filing reports only the first tranche as funded.
The amendment allows up to $120.0 million of term loans, with a $42.0 million first tranche that refinanced existing loans. Interest carries a floor of 10.25%, lenders can convert up to $7.0 million into shares, and the 8-K gives no cash balance or net loss.
What Definium Therapeutics does
Definium Therapeutics is a late-stage clinical biopharmaceutical company developing product candidates for brain health disorders, drawn from psychedelic and empathogen drug classes. Its lead candidate, DT120 ODT, is a pharmaceutically optimized form of lysergide D-tartrate in development for generalized anxiety disorder (GAD) and major depressive disorder (MDD). After a Phase 2b trial in GAD met its primary endpoint, the FDA granted breakthrough designation to the DT120 program for GAD in March 2024. Its Phase 3 program for GAD consists of two trials, Voyage and Panorama, and a Phase 3 trial in MDD, Ascend, had sites activated in the first quarter of 2026. Its Voyage trial is expected to report Part A topline results in early third quarter 2026. DT402, also referred to as R(-)-MDMA, is being developed for autism spectrum disorder. The company completed a first clinical trial of DT402 in adult healthy volunteers in October 2024 and initiated a Phase 2a trial in autism spectrum disorder in the fourth quarter of 2025. The company says it applies scientific rigor to psychedelics with the goal of developing accessible treatments for brain health disorders.
