Background: Pegfilgrastim is a long-acting recombinant human granulocyte colony-stimulating factor biologic that is indicated to reduce the incidence of infections, manifested by febrile neutropenia, in patients receiving myelosuppressive anti-cancer drugs and to increase survival in patients acutely exposed to myelosuppressive doses of radiation. Due to the high cost of biologic therapy and the scarcity of biosimilar alternatives, there is an unmet medical need for targeted biologics.
Objective: This comparative analytical investigation aimed to confirm the similarity of biosimilar Stimufend® (pegfilgrastim-fpgk) to reference product Neulasta® (pegfilgrastim).
