Arialys Therapeutics secures U.S. FDA Fast Track designation for **ART5803**, its first precision therapy targeting **anti-NMDA receptor encephalitis (ANRE)**. The company develops autoimmune neuropsychiatric disease treatments, and ART5803 uses structural biology to block autoantibodies driving ANRE pathology. This designation accelerates clinical development for a rare, severe neurological disorder with limited treatment options.
