Alnylam Pharma. NDA for Givosiran Filed
FDA has accepted for review an Alnylam Pharmaceuticals NDA for givosiran, an investigational RNAi therapeutic targeting aminolevulinic acid synthase 1 (ALAS1) for treating acute hepatic porphyria. The agency has granted a priority review and set a 2/4/2020 user fee review action target date.
Givosiran is intended to lower induced liver ALAS1 levels and “thereby decrease neurotoxic heme intermediates, aminolevulinic acid (ALA) and porphobilinogen (PBG), towards normal levels,” the company says. “By reducing accumulation of these intermediates, givosiran has the potential to prevent or reduce the occurrence of severe and life-threatening attacks, control chronic symptoms, and decrease the burden of the disease.”
