Stimufend® (pegfilgrastim-fpgk), a biosimilar to Neulasta® (pegfilgrastim), has been made available by Fresenius Kabi.

Stimufend, a leukocyte growth factor, is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with nonmyeloid malignancies receiving myelosuppressive anticancer drugs associated with a clinically significant incidence of febrile neutropenia.
