Givosiran  (Synonyms: ALN-AS1)

Givosiran (ALN-AS1) is a small interfering RNA that targets hepatic aminolevulinate synthase 1 (ALAS1) messenger RNA. Givosiran downregulates ALAS1 mRNA and prevents accumulation of neurotoxic δ-aminolevulinic acid and porphobilinogen levels. Givosiran can be used for the research of acute intermittent porphyria^[1][2].

Givosiran is conjugated to a trivalent N-acetylgalactosamine ligand, which binds specifically to the asialoglycoprotein receptor, enabling targeted delivery to hepatocytes^[2].
