Fazirsiran

(Synonyms: ARO-AAT)

Fazirsiran (ARO-AAT) is a second-generation RNAi agent. Fazirsiran consistes of a cholesterol-conjugated RNAi trigger (chol-RNAi) to selectively reduce Alpha1-antitrypsin (AAT) synthesis and a melittin-derived peptide conjugated to N-acetylgalactosamine (NAG) formulated as the excipient EX1 to promote endosomal escape of the chol-RNAi in hepatocytes. Fazirsiran can be used in the study of Alpha-1 Antitrypsin Deficiency (AATD) liver disease. Alpha-1 antitrypsin deficiency (AATD) is caused by mutations in the alpha-1 antitrypsin (SERPINA1) gene.

The free form of the compound is prone to instability, it is advisable to consider the stable salt form (Fazirsiran sodium) that retains the same biological activity.
