STIMUFEND (pegfilgrastim-fpgk)
Stimufend is a leukocyte growth factor indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in patients with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs. It is also approved to increase survival in patients acutely exposed to myelosuppressive doses of radiation, a condition known as Hematopoietic Subsyndrome of Acute Radiation Syndrome. The drug is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.
How STIMUFEND Works
Stimufend is a colony-stimulating factor that acts on hematopoietic cells by binding to specific cell surface receptors. This binding process stimulates the proliferation, differentiation, and commitment of these cells. Furthermore, the mechanism facilitates the functional activation of end cells to support the immune system.
