- Alnylam Pharmaceuticals recently presented new clinical and real-world data at the 2026 European Society of Cardiology Congress showing that its RNAi therapy AMVUTTRA (vutrisiran) maintained clinical benefits across ATTR amyloidosis patient groups, while investigational agent zilebesiran delivered enhanced blood pressure reductions in high-risk patients with uncontrolled hypertension.
