About ulotaront (SEP-363856)

Ulotaront (SEP-363856) is an amine-associated receptor 1 (TAAR1) agonist with serotonin 5-HT1A agonist activity, jointly developed by Sunovion and PsychoGenics Inc, which is a small molecule oral agent that does not bind to dopamine D2 or serotonin 5-HT2A receivers. Sunovion discovered ulotaront in collaboration with PsychoGenics using its in vivo phenotypic SmartCube® platform and associated artificial intelligence algorithms. The results of the phase 2 study confirmed efficacy in treating both positive and negative symptoms of schizophrenia while demonstrating a side effect profile with notable similarities to placebo with regard to extrapyramidal symptoms, weight gain, lipid and glycemic disorders and elevation of prolactin. The full results of the study have been published in the New England Journal of Medicine (NEJM) in April 2020.

The agent is currently in phase 3 studies for schizophrenia in the United States and in phase 2/3 global clinical studies in Japan and China, with further indications under study. The United States Food and Drug Administration (FDA) granted breakthrough therapy designation to ulotaront for the treatment of schizophrenia in May 2019.

About SEP-4199

SEP-4199 is an oral small molecule agent with a non-racemic enantiomeric ratio of amisulpride developed by Sunovion. Sunovion discovered that the pharmacology of amisulpride is enantiomer-specific and that increasing the R-amisulpride / S-amisulpride ratio increases the potency of 5-HT serotonin.7 dopamine D receptors2 receivers. SEP-4199 was designed with an 85:15 ratio of R-amisulpride to S-amisulpride to increase serotonin 5-HT levels7 activity to improve the effectiveness of antidepressants and produce reduced levels of D2 receptor occupation appropriate for the treatment of bipolar depression. In September 2021, Sunovion launched a global Phase 3 clinical study, which is a randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study for the treatment of bipolar I depression in the United States. Japan will join this global clinical phase 3 study.

About SEP-378614

SEP-378614, jointly discovered by Sunovion and PsychoGenics, is a small molecule oral agent that acts on the central nervous system. Sunovion discovered SEP-378614 in collaboration with PsychoGenics using its in vivo phenotypic SmartCube® platform and associated artificial intelligence algorithms. The results of preclinical studies suggest that it may have rapid-onset and long-lasting antidepressant-like activity and improve neuroplasticity.
