Noridian Healthcare Solutions opened a draft local coverage determination for gene tests for heritable thoracic aortic disease per a request from Invitae Corp., of San Francisco, which makes a comprehensive panel test for aortopathy.
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.
Bearish investors dwelling on a single grade 4 liver enzyme elevation seemed to be the cause for Intellia Therapeutics Inc.’s sinking stock Sept. 16, despite the company reporting impressive, though early stage, data for its leading systemically administered CRISPR candidates targeting hereditary angioedema (HAE) and amyloid transthyretin (ATTR) amyloidosis.
Alnylam Pharmaceuticals Inc.’s Amvuttra (vutrisiran), a treatment for the rare disease hereditary transthyretin-mediated amyloidosis, was among medicines recommended for approval by regulators from Europe’s Committee for Medicinal Products for Human Use (CHMP) in a busy sitting.
With Alnylam Pharmaceuticals Inc.’s FDA clearance for Amvuttra (vutrisiran) in the rearview mirror, investors are looking ahead to potentially label-widening phase III data related to another, already approved drug: Onpattro (patisiran).
As the company unveiled 18-month results from the phase III study called Helios-A, Alnylam Pharmaceuticals Inc.’s president of R&D, Akshay Vaishnaw, said “new exploratory data with the cardiac endpoints are extremely encouraging.” The study is testing RNAi therapy vutrisiran in polyneuropathy associated with hereditary transthyretin-mediated (hATTR) amyloidosis, where Helios-A met all secondary endpoints measured at 18 months.
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.
