Inotersen NDA Accepted for Priority Review by FDA

Ionis Pharmaceuticals announced its New Drug Application (NDA) for inotersen has been accepted for Priority Review by the U.S. Food and Drug Administration (FDA). Inotersen is an investigational drug for the treatment of patients with hereditary TTR amyloidosis (hATTR). Priority Review is granted by the FDA to drugs with the potential to address a serious condition and, if approved, would provide a significant improvement in safety or effectiveness of the treatment, prevention, or diagnosis of a serious condition. The FDA has set a Prescription Drug User Fee Act (PDUFA) date of July 6, 2018.

"TTR amyloidosis is a progressive, fatal disease with very limited treatment options. Receiving Priority Review in the U.S. and Accelerated Assessment in the EU for inotersen shows that the regulatory agencies recognize the high unmet need and the urgency to identify effective therapies to treat patients with this devastating disease," said Sarah Boyce, chief business officer of Ionis Pharmaceuticals. "We continue our launch preparations for inotersen and are on track to launch inotersen promptly in the U.S. and EU if approved."
