A new self-injectable therapy for polyneuropathy of hereditary transthyretin-mediated amyloidosis (hATTR-PN) will be available in January 2024 now that the U.S. FDA has approved Ionis Pharmaceuticals Inc.’s Wainua (eplontersen), a ligand-conjugated antisense oligonucleotide.
Following an unexpected FDA complete response letter (CRL), Alnylam Pharmaceuticals Inc. said it will no longer pursue an expanded indication for Onpattro (patisiran) in the U.S. The RNAi therapeutic was approved in 2018 to treat polyneuropathy of hereditary transthyretin-mediated (ATTR) amyloidosis and seemed well on its way to snagging a second U.S. indication after the FDA’s Cardiovascular and Renal Drugs Advisory Committee voted 9-3 in September that the drug’s benefits outweighed its risks as a treatment for cardiomyopathy of ATTR amyloidosis. The FDA disagreed with the committee, saying in the CRL that patisiran’s clinical meaningfulness had not been established in the proposed indication.

Alnylam Pharmaceuticals Inc. said the 164-patient Helios-A phase III study with next-generation RNAi drug vutrisiran hit its primary endpoint as well as both secondary goals in the treatment of hereditary transthyretin-mediated amyloidosis with polyneuropathy. The primary endpoint was change from baseline in the modified Neuropathy Impairment Score at nine months as compared to historical placebo data from the Apollo phase III study of Alnylam’s Onpattro, cleared by the FDA for ATTR polyneuropathy in August 2018.
Intellia Therapeutics Inc. is looking to disrupt the transthyretin (TTR) amyloidosis (ATTR) market with NTLA-2001, its CRISPR-based treatment designed to be a potential cure for the disease. The drug, which is delivered via a lipid nanoparticle, edits the patient's DNA in vivo to create a stop codon and eliminate the expression of TTR, the protein that aggregates in ATTR patients' nervous systems and hearts, disrupting their functions.
