CARLSBAD, Calif. - Ionis Pharmaceuticals, Inc. (NASDAQ:IONS) has confirmed plans to initiate a Phase 3 study for ION582, a potential treatment for Angelman syndrome (AS), in the first half of 2025. The decision follows a successful meeting with the U.S. Food and Drug Administration (FDA), where they reached an agreement on the final study design.
The Phase 3 trial, dubbed the REVEAL study, aims to enroll roughly 200 children and adults with AS, specifically those with a maternal UBE3A gene deletion or mutation. The primary focus of the study is to assess improvements in expressive communication using the Bayley Scales for Infant and Toddler Development-4 (Bayley-4). This endpoint was chosen as deficits in expressive communication are among the most challenging symptoms for caregivers of individuals with AS.
ION582 will be administered at two different dose levels, with patients receiving the treatment quarterly. After a year of treatment, a primary analysis will be conducted, followed by an open-label long-term extension phase. The study will also monitor several secondary endpoints, including overall disease severity and cognitive and motor functioning.
The upcoming Phase 3 study builds on the promising results from the Phase 2 HALOS trial, where ION582 demonstrated clinically meaningful improvements across various functional domains, including communication and motor function. The data indicated that 97% of participants in the medium and high dose groups experienced an improvement in overall AS symptoms.
ION582 is an investigational antisense medicine designed to inhibit the UBE3A antisense transcript and increase the production of UBE3A protein. Last year, the FDA granted ION582 Orphan Drug and Rare Pediatric Disease designations, recognizing the potential benefits for treating AS, a condition with no approved disease-modifying therapies.
Ionis Pharmaceuticals, a leader in RNA-targeted therapies, has a robust neurology franchise, including approved treatments for spinal muscular atrophy and hereditary transthyretin-mediated amyloid polyneuropathy. The company's pipeline also features investigational medicines for rare diseases like Prion disease and Alexander disease, as well as more common conditions such as Alzheimer's and Parkinson's disease.
The company is expected to share further updates on the ION582 program at the FAST Global Science Summit later this week. This article is based on a press release statement from Ionis Pharmaceuticals.
