ACT-539313 is an orexin antagonist medication which is under development for the treatment of binge eating disorder and was previously under development for the treatment of anxiety disorders.[4][5][6][7][1][2] It is an orally active small-molecule compound with an elimination half-life of 3.3 to 6.5 hours and acts as a selective orexin OX1 receptor antagonist (1-SORA).[4][1][2] As of May 2022, the drug is in phase 2 clinical trials for binge eating disorder.[4] Following negative efficacy results of a phase 2 trial of ACT-539313 for binge eating disorder, Idorsia (the developer of ACT-539313) signaled in May 2022 that it would not pursue further development of the drug for this indication.[8]
