CAMBRIDGE, Mass.– Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), the leading RNAi therapeutics company, announced that the U.S. Food and Drug Administration (FDA) has extended the review timeline of the New Drug Application (NDA) for vutrisiran, an investigational RNAi therapeutic in development for the treatment of transthyretin-mediated (ATTR) amyloidosis, to allow for the review of newly added information related to the new secondary packaging and labeling facility. Alnylam recently learned that the original third-party secondary packaging and labeling facility the Company planned to use for the vutrisiran launch was recently inspected and the inspection requires classification for the FDA to take action on the vutrisiran NDA. The inspection observations were not directly related to vutrisiran. In order to minimize delays to approval, Alnylam has identified a new facility to pack and label vutrisiran and submitted an amendment to the NDA for review by the FDA. The updated Prescription Drug User Fee Act (PDUFA) goal date to allow for this review is July 14, 2022. No additional clinical data have been requested by the FDA.
“We are committed to working with the FDA and the new facility to bring this important treatment option as quickly as possible to patients living with the polyneuropathy of hATTR amyloidosis, an inherited, progressively debilitating, and fatal disease,” said Pushkal Garg, M.D., Chief Medical Officer & EVP, Development and Medical Affairs. “We are confident in our regulatory application and the body of data supporting the efficacy and safety of vutrisiran.”
Vutrisiran is also under review by the European Medicines Agency (EMA), the Brazilian Health Regulatory Agency (ANVISA) and the Japanese Pharmaceuticals and Medical Devices Agency (PMDA). We aim to minimize the impact of this issue on these reviews through timely resolution of the matter or utilization of an alternative facility for one or more of these regions. Vutrisiran has been granted Orphan Drug Designation in the U.S. and the European Union (EU) for the treatment of ATTR amyloidosis, and in Japan for transthyretin type familial amyloidosis with polyneuropathy.
