生物活性:
Vutrisiran (ALN-TTRsc02) is a liver-directed, investigational, small interfering ribonucleic acid (siRNA) agent. Vutrisiran can be used for transthyretin (TTR)-mediated amyloidosis research.

体内研究:
In non-human primates, single SC doses of Vutrisiran 0.3 and 1 mg/kg achieved mean maximum TTR reductions (nadirs) of 55% and 96%, respectively, with serum TTR reductions persisting beyond 4 months for the 1 mg/kg dose. In the same study, monthly doses of 1 and 3 mg/kg maintained a reduction of TTR levels at 96%, relative to baseline.

体外研究:
Vutrisiran (previously ALN-TTRSC02) is a second-generation investigational RNAi therapeutic under development for the study of ATTR amyloidosis. Vutrisiran contains an siRNA that targets a sequence within the TTR mRNA which is conserved across wt and all known TTR variants. However, the Vutrisiran siRNA utilizes enhanced stabilization chemistry (ESC) and is conjugated to a triantennary GalNAc ligand, with the aim of enabling infrequent, subcutaneous (SC) dosing.
