Givosiran

Givosiran is a small interfering RNA (siRNA) directed towards 5-aminolevulinic acid synthase, a critical enzyme in the heme biosynthesis pathway. It is manufactured by Alnylam Pharmaceuticals and was first approved for use in the United States in November 2019 for the treatment of adults with acute hepatic porphyria, a genetic disorder in which the overproduction of toxic heme intermediates leads to neuro-, nephro-, and gastrotoxicity. Givosiran represents an important step forward in the treatment of acute hepatic porphyria as it is the first approved pharmacotherapy for the prevention of acute attacks - previous strategies involved non-therapeutic measures (e.g. trigger avoidance), intravenous hemin for the treatment of attacks, and liver transplantation in refractory cases. Givosiran is the second-ever FDA-approved member of the siRNA drug class (the first being patisiran), a new class of drugs promising an important and exciting step forward in the treatment of genetic disorders.
