FYLNETRA (pegfilgrastim-pbbk)
FYLNETRA is a leukocyte growth factor indicated to decrease the incidence of infection, manifested as 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. This medication is not indicated for the mobilization of peripheral blood progenitor cells for hematopoietic stem cell transplantation.
How FYLNETRA Works
FYLNETRA 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. Additionally, the drug triggers end cell functional activation to support the production and activity of white blood cells.
