Sage Therapeutics Announces European Medicines Agency Granted SAGE-718 Orphan Drug Designation for the Treatment of Huntington’s Disease
“Huntington’s disease is a serious, debilitating condition that interferes with daily functioning in the prime years of life and is associated with significant morbidity and early mortality, and yet there are currently no approved therapies for the treatment of HD-related cognitive impairment,” said
Orphan drug designation is reserved for medicines treating rare, life-threatening, or chronically debilitating diseases that meet certain specified criteria. Potential benefits for Sage as a result of this designation include Protocol Assistance or scientific advice specifically designed for orphan medicines, European centralized authorization procedure, if development is successful and a marketing authorization application is filed, and if approved, ten years of market exclusivity and protection from similar medicines with the same indication being approved.
SAGE-718, Sage’s first-in-class NMDA receptor positive allosteric modulator (PAM) and lead neuropsychiatric drug candidate, is in development as a potential oral therapy for cognitive disorders associated with NMDA receptor dysfunction, potentially including HD, PD and AD. Sage is advancing a robust clinical program for SAGE-718 with multiple ongoing placebo-controlled Phase 2 studies across multiple disease areas, including its potential lead indication, cognitive impairment associated with HD, as well as cognitive impairment due to AD and PD. The Company is also conducting a Phase 3 safety extension study in HD cognitive impairment. SAGE-718 has received Fast Track Designation from the FDA for the potential treatment of HD.
