The U.S. Food and Drug Administration (FDA) approved Alnylam Pharmaceuticals’ ALNY  lead drug candidate AMVUTTRA (Vutrisiran) for the treatment of the polyneuropathy of hereditary transthyretin-mediated (hATTR) amyloidosis in adults.

During the Phase 3 clinical trial, Vutrisiran met primary and all secondary endpoints, with Significant Improvement in Polyneuropathy, Quality of Life and Gait Speed Relative to External Placebo.
