EU Approves Ionis Pharmaceuticals' DAWNZERA for Hereditary Angioedema Prevention

Ionis Pharmaceuticals Inc. and Otsuka Pharmaceutical Co., Ltd. announced that the European Commission has approved DAWNZERA™ (donidalorsen) for the routine prevention of recurrent attacks of hereditary angioedema $(HAE)$ in adults and adolescents aged 12 years and older in the European Union. The approval is based on positive results from the Phase 3 OASIS-HAE and OASISplus studies, where DAWNZERA demonstrated a significant reduction in HAE attack rates. Otsuka holds exclusive rights to commercialize DAWNZERA in Europe and Asia Pacific. With this approval, Ionis is eligible for a milestone payment of $15 million and tiered royalties up to 30% on net product sales.
