ION582 is an investigational RNA-targeted antisense medicine designed to inhibit the expression of the UBE3A antisense transcript (UBE3A-ATS) and increase production of UBE3A protein. The FDA and European Medicines Agency (EMA) have already granted Orphan Drug designation to ION582, and the FDA has also granted Fast Track and Rare Pediatric designations to the drug [1].
The orphan drug designation for ION582 comes as the company continues to expand its pipeline in neurology, cardiometabolic disease, and other areas of high patient need. Ionis has five marketed medicines, including SPINRAZA® (nusinersen) for spinal muscular atrophy, WAINUA® (eplontersen) for hereditary transthyretin-mediated amyloid polyneuropathy, and QALSODY® (tofersen) for SOD1-ALS [1].
Ionis' progress with ION582 underscores the company's commitment to developing innovative treatments for rare and serious diseases. The company's forward-looking statements indicate that it remains focused on advancing its pipeline and delivering life-changing advances for patients [1].
