Name of IMP
Vutrisiran (ALN-TTRSC02)
Type of IMP
Gene therapy
Pharmaceutical class
Synthetic RNA interference (RNAi) therapeutic molecule
Therapeutic indication
Transthyretin Amyloidosis (ATTR) With Cardiomyopathy
Therapeutic benefit
Vutrisiran utilizes RNAi to prevent the synthesis of both wt and mutant TTR in the liver, the primary source of circulating TTR. TTR reduction with vutrisiran will beneficially impact disease progression in patients with ATTR amyloidosis with cardiomyopathy.
Biospecimen retention
Samples with DNA**
Biospecimen description
Biological specimens will be collected, may include DNA, RNA, or biochemical metabolite assessments as they relate to disease progression, efficacy or safety. The biospecimen repository will also include residual material from routine samples (safety laboratory samples, PK samples, etc.) that are obtained during the study.
