NEW YORK--(BUSINESS WIRE)--Apr. 18, 2026--
Definium Therapeutics, Inc. (“Definium” or the “Company”), a late-stage clinical biopharmaceutical company developing a new generation of therapies targeting the underlying causes of psychiatric and neurological disorders, today issued the following statement supporting the newly signed White HouseExecutive Order aimed at accelerating research, development, and responsible access to innovative treatments for serious mental illness, including emerging psychedelic medical treatments:
“Accelerating scientific progress depends on both rigor and urgency, and we thank the Administration and welcome this Executive Order as an important recognition of the persistent unmet treatment needs in serious mental illness,” said Rob Barrow, Chief Executive Officer of Definium Therapeutics. “We applaud the Administration’s recognition that psychedelic medicines may represent meaningful new treatment options for patients. We are advancing a comprehensive clinical development program for DT120 (lysergide tartrate) for millions of patients living with conditions including generalized anxiety disorder (GAD) and major depressive disorder (MDD). A science-driven framework that supports rigorous evaluation, responsible access, and faster translation of innovation into care is essential, and the FDA’s evidence-based approval process provides the most effective path to safely delivering these therapies to patients.”
The Executive Order directs coordinated federal action to prioritize mental health therapies, streamline regulatory pathways, and expand cross-agency collaboration, consistent with the Administration’s policy to accelerate innovative research models and appropriate drug approvals to increase access to psychedelic medicines that could help save lives and address the serious mental health crisis in America. Definium Therapeutics remains committed to advancing rigorous clinical science to develop safe and effective psychedelic treatments and looks forward to continued collaboration with federal agencies, clinicians, researchers, and patient communities to advance evidence-based solutions for mental health disorders.
About DT120 Orally Disintegrating Tablet (ODT)
DT120 ODT (lysergide tartrate) 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). DT120 ODT is Definium’s proprietary and pharmaceutically optimized formulation of LSD. DT120 ODT is an advanced formulation incorporating Catalent’s Zydis® ODT fast-dissolve technology, designed to deliver several unique advantages, including faster absorption and onset of transient cognitive, perceptual, and affective changes, improved bioavailability, and a lower incidence of gastrointestinal side effects. Definium is developing DT120 ODT, 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.
