Takeda Pharmaceutical Company presented additional positive results from two pivotal studies (FirstLight and RadiantLight) at SLEEP 2026 for its investigational drug, oveporexton (TAK-861). The oral orexin receptor 2 (OX2R)-selective agonist demonstrated significant improvements in daily functioning, cognitive symptoms, and nighttime sleep for patients with narcolepsy type 1 (NT1). Oveporexton is designed to address the underlying orexin deficiency in NT1 by restoring orexin signaling. These data, combined with previously disclosed Phase 3 results, suggest oveporexton could redefine the standard of care for NT1. The United States — Food and Drug Administration has accepted the New Drug Application and granted Priority Review for oveporexton, with a Prescription Drug User Fee Act (PDUFA) goal date in the third quarter of this calendar year. Regulatory submissions are also under review in China and Japan, with more planned.
