Ionis initiates pivotal clinical study of novel antisense medicine to treat patients with Alexander disease
ION373 is one of Ionis' wholly owned medicines that the company plans to commercialize as part of its strategy to develop and commercialize rare disease medicines primarily focused on its core neurological and cardiometabolic franchises.
"Initiation of a pivotal study of ION373 marks an important step toward bringing a novel disease modifying therapy to Alexander disease patients afflicted by this devastating disorder. The ability to begin our clinical program with a pivotal study serves as a testament to how Ionis' long-standing collaboration with the patient, medical and research communities can lay the foundation for an aggressive clinical path," said
Alexander disease has been estimated to occur in about one in one million births. ION373 has received orphan drug designation and rare pediatric disease designation from the
The Phase 2/3 study of ION373 is a multi-center, double-blind, placebo-controlled, multiple-ascending dose (MAD) study in up to 58 patients with Alexander disease. Patients will receive ION373 or placebo for a 60-week period, after which all patients in the study will receive ION373 for a 60-week open-label treatment period.

About Alexander disease
Alexander disease is a rare neurological condition characterized as a leukodystrophy, or a disease affecting the myelin sheath (the fatty insulation that protects a nerve fiber and supports signal conduction). It is caused by overproduction and toxic accumulation of GFAP in astrocytes. Clinically, Alexander disease presents with a range of symptoms that may include seizures, motor and cognitive development delay, encephalopathy, weakness, spasticity, pseudobulbar/bulbar symptoms and macrocephaly. Age of disease onset is variable, occurring from birth through young adulthood, with childhood onset generally more severe. There are treatments that can relieve symptoms, but there is no disease modifying therapy yet available to patients.
For more than 30 years, Ionis has been the leader in RNA-targeted therapy, pioneering new markets and changing standards of care with its novel antisense technology. Ionis currently has three marketed medicines and a premier late-stage pipeline highlighted by industry-leading neurological and cardiometabolic franchises. Our scientific innovation began and continues with the knowledge that sick people depend on us, which fuels our vision of becoming one of the most successful biotechnology companies.
