NYPOZI

FILGRASTIM-TXID
Oncology Approved 2024-06-28

NYPOZI (filgrastim-txid) is a leukocyte growth factor used to manage neutropenia and reduce the risk of associated infections in several patient populations. It is indicated for patients with nonmyeloid malignancies receiving myelosuppressive or myeloablative chemotherapy, as well as those with acute myeloid leukemia or chronic forms of neutropenia. Additionally, the drug is used to mobilize hematopoietic progenitor cells for collection and to increase survival following acute exposure to myelosuppressive doses of radiation.

How NYPOZI Works

NYPOZI functions as a colony-stimulating factor that binds to specific cell surface receptors on hematopoietic cells. This binding stimulates the proliferation, differentiation, and activation of neutrophil progenitors within the bone marrow. By mimicking endogenous G-CSF, the drug specifically regulates the production of neutrophils and enhances their functional abilities, such as phagocytosis and antibody-dependent killing, with minimal effect on other cell lineages.
