Mind Medicine (MindMed (搜索)) Inc. has rebranded as Definium Therapeutics (搜索), marking a strategic transformation as the company prepares for three pivotal Phase 3 data readouts in 2026 that could reshape psychiatric treatment. The rebrand reflects the company's evolution from an early-stage psychedelic research firm to a late-stage clinical leader positioned to bring novel therapies to market.
"Definium Therapeutics (搜索) reflects the core of who we've always been and where we're headed - disciplined execution, scientific leadership, and a vision to develop accessible treatments that can unlock healing at scale," said Rob Barrow, Chief Executive Officer of Definium Therapeutics. The company's shares now trade under the Nasdaq ticker symbol "DFTX."
Three Phase 3 Studies Target Major Psychiatric Markets
Definium is advancing DT120 (搜索) Orally Disintegrating Tablet (ODT) toward FDA submissions in generalized anxiety disorder (搜索) (GAD) and major depressive disorder (搜索) (MDD), which together affect over 50 million people in the U.S. The company's lead candidate has received FDA Breakthrough Therapy Designation for GAD, highlighting its potential clinical significance.

Expanding Pipeline Beyond Core Indications

"We are unwavering in our mission to forge a new era of psychiatry by applying scientific rigor to psychedelics," Barrow stated. "By retracing LSD to its origins, we aim to fully realize its clinical potential as a safe and transformative therapeutic."
Strategic Leadership Addition
To support its transition toward commercialization, Definium appointed Roger Adsett to its Board of Directors. Adsett brings over two decades of biopharmaceutical experience, currently serving as Chief Operating Officer of Insmed, where he has overseen commercial strategy and the successful launches of ARIKAYCE® and BRINSUPRI®.
"Roger is a respected and proven leader with deep experience building high-performing commercial organizations and guiding transformational therapies from launch to meaningful market impact," said Barrow. Adsett previously held senior leadership positions at Shire and AstraZeneca, including roles in the launches of blockbuster therapies Nexium® and Symbicort®.
Mission-Driven Approach to Mental Health
The rebrand to Definium Therapeutics (搜索) emphasizes the company's commitment to developing treatments that address underlying causes of psychiatric and neurological disorders rather than providing transient symptom reduction. According to Chief Corporate Affairs Officer Stephanie Fagan, "'Definio' speaks to our clear sense of direction and scientific precision, and 'infinitum' to being open to what hasn't been done before and the impact we can have on the world."
The company plans to host an Analyst Day in the second quarter of 2026, highlighting its pivotal programs, pipeline, and path to commercialization as it prepares for potential product launches in the world's largest psychiatric markets.
