Alnylam Pharmaceuticals, Inc.  announced that the Company will present the latest data from its flagship transthyretin amyloidosis (TTR) franchise at the upcoming Heart Failure 2025 Congress, a scientific congress of the European Society of Cardiology, taking place May 17-20 in Belgrade, Serbia. The latest analyses of the HELIOS-B Phase III study of vutrisiran in patients with ATTR amyloidosis with cardiomyopathy (ATTR-CM), including further outcomes data on cardiovascular hospitalizations and urgent heart failure visits up to 42-months, will be presented as a late-breaking abstract.

Data from the HELIOS-B study supported the recent approvals of  Amvuttra (vutrisiran) for the treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis in adults in the U.S. and Brazil. These data also supported the positive opinion from the Committee for Medicinal Products for Human Use (CHMP) of the EMA recommending approval of vutrisiran for the same indication. 

Details are as follows:
