Bendamustine is a nitrogen mustard drug indicated for use in the treatment of chronic lymphocytic leukemia (CLL) and indolent B-cell non-Hodgkin lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen. Bendamustine is a bifunctional mechlorethamine derivative capable of forming electrophilic alkyl groups that covalently bond to other molecules. Through this function as an alkylating agent, bendamustine causes intra- and inter-strand crosslinks between DNA bases resulting in cell death. It is active against both active and quiescent cells, although the exact mechanism of action is unknown.
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.
