Ionis treatment for Alexander disease granted orphan drug status from EMA

February 11, 2020 at 7:05 AM EST

CARLSBAD, Calif., Feb. 11, 2020 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (NASDAQ: IONS), the leader in RNA-targeted therapeutics, announced today that the European Medicines Agency (EMA) has granted orphan drug designation to ION373 for the treatment of people with Alexander disease, a severe, progressive and debilitating condition that can eventually result in death due to loss of control over autonomic functions like breathing. Infants and young children who develop the condition rarely survive beyond their teenage years or young adulthood.

Orphan drug designation by the EMA 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.

Alexander disease affects approximately 500 people in the EU. It is caused by a mutation in a protein that creates overproduction of glial fibrillary acidic protein (GFAP) in the brain. ION373 is designed to stop the mutated gene from producing excess GFAP.

"We look forward to working closely with European regulators, clinical investigators, Alexander disease patients and their families to advance this important medicine and make it available to those who need it," said Brett P. Monia, Ph.D., Ionis' chief executive officer. "Receiving orphan drug status reflects the urgent need for ION373, which is among a number of wholly-owned, novel drugs in the Ionis pipeline that we are prioritizing."
