Profile
Develops psychedelic- and empathogen-derived drug candidates for psychiatric and neurological disorders, led by Phase 3 lysergide tablet DT120 ODT for anxiety and depression and early-stage R(-)-MDMA candidate DT402 for autism. With no approved products or product sales, the business depends on clinical and regulatory success under controlled-substance rules.
Develops investigational medicines derived from psychedelic and empathogen drug classes for psychiatric and neurological disorders. The pipeline centers on DT120 ODT, an orally disintegrating form of lysergide tartrate in Phase 3 programs for generalized anxiety disorder and major depressive disorder, with a posttraumatic stress disorder study planned. Positive topline results have been reported from pivotal anxiety and depression studies; additional studies in both conditions continue.
Also advances DT402, a proprietary R(-)-MDMA candidate in an early-stage autism spectrum disorder study. Operations are centered in the United States, with global headquarters in New York. No product is approved or generating sales, making the business dependent on clinical results, regulatory approval and commercialization. Both lead compounds are controlled substances, adding registration, handling and scheduling requirements.
