Additional positive 9-month results from subgroup analyses and exploratory endpoints of the HELIOS-A Phase 3 study of vutrisiran, an investigational RNAi therapeutic in development for the treatment of transthyretin-mediated (ATTR) amyloidosis with polyneuropathy, were presented at the 3rd EU-ATTR Amyloidosis Meeting. Subgroup analyses and exploratory endpoints demonstrated that vutrisiran improved important areas of patient health and function compared with placebo at 9 months. Additional analyses showed similar improvements in progression of neuropathy and quality of life measures with vutrisiran compared with placebo, regardless of prior TTR stabilizer use.
