We are a late-stage clinical biopharmaceutical company developing novel product candidates to treat brain health disorders. 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. We are developing a pipeline of innovative product candidates targeting neurotransmitter pathways that play key roles in brain health disorders. This specifically includes pharmaceutically optimized product candidates derived from the psychedelic and empathogen drug classes including DT120 (previously referred to as MM120), and DT402 (previously referred to as MM402), our lead product candidates.

Our first lead product candidate, DT120 ODT, is a proprietary, pharmaceutically optimized form of lysergide D-tartrate that we are developing for the treatment of adults with generalized anxiety disorder and major depressive disorder. In December 2023, we announced positive topline results from our Phase 2b clinical trial of DT120 for the treatment of GAD. The trial met its primary endpoint, with DT120 demonstrating statistically significant and clinically meaningful dose-dependent improvements on the Hamilton Anxiety Rating Scale ("HAM-A") compared to placebo at Week 4. In March 2024, we announced that the U.S. Food and Drug Administration ("FDA") granted breakthrough designation to our DT120 program for the treatment of GAD.
