Director, Medical Communications

Definium Therapeutics is a late-stage clinical biopharmaceutical company and our mission is to forge a new era of psychiatry by applying scientific rigor to psychedelics, with the goal of developing accessible treatments that unlock healing at scale.

Our lead product candidate, lysergide tartrate (our proprietary orally disintegrating tablet form of lysergide (LSD) D-tartrate), represents a highly differentiated, potential best-in-class opportunity for patients suffering from generalized anxiety, major depressive disorder, and posttraumatic stress disorder. Our early stage pipeline includes DT402, the R-enantiomer of MDMA and is under development to target the core symptoms of autism spectrum disorder (ASD), specifically addressing social communication challenges.

Guided by the recognition that patients deserve more than better, Definium is relentlessly advancing a new generation of therapeutics intended to address the underlying causes of psychiatric and neurological disorders. By turning evidence into impact, Definium aims to change the trajectory of today’s mental health care crisis and enable a healthier future. Headquartered in New York, Definium Therapeutics trades on Nasdaq under the symbol DFTX.

Together we are moving psychiatry forward—beyond better, into a boundless future. Join us!
