ION373: The first drug for AxD in clinical trial.

Drug Development

Ionis Pharmaceuticals, Inc. develops treatments target-focused on RNA. Ionis previously developed a drug to successfully treat SMA, a neuro-muscular disorder, and they have developed a new drug, ION373, for AxD, that uses the same intrathecal delivery method.

European Medicines Agency (EMA) has granted orphan drug designation to ION373 for the treatment of people with Alexander Disease. This designation provides regulatory and financial incentives to develop therapies for life threatening or chronically debilitating conditions affecting not more than five in 10,000 people in the European Union (EU) and for which there is no satisfactory method of diagnosis, prevention or treatment. Upon approval, drugs that have been granted orphan designation by the EMA receive market exclusivity for 10 years in the EU.
