08 Nov, 2025 New Analyses from Amyloidosis and Hypertension Programs Presented at the American Heart Association (AHA) Scientific Sessions 2025

New analyses highlight that vutrisiran improved measures of heart structure and function and reduced amyloid burden in some patients.

Further findings show vutrisiran preserved kidney function and reduced the risk of death and cardiovascular (CV) events in patients with advanced chronic kidney disease (CKD).

Results from Cohort B of the KARDIA-3 Phase 2 trial evaluating zilebesiran in patients with uncontrolled hypertension with established or at high risk for CV disease on two or more background medications were also presented as a late-breaking abstract.
