Pegfilgrastim

Monoclonal antibody

Pegfilgrastim, sold under the brand name Neulasta among others, is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (GCSF) analog filgrastim.[16] It serves to stimulate the production of white blood cells (neutrophils).[16][18] Pegfilgrastim was developed by Amgen.[19]

Quick Facts Clinical data, Trade names ...

Pegfilgrastim treatment can be used to stimulate bone marrow to produce more neutrophils to fight infection in patients undergoing chemotherapy.[20]

Pegfilgrastim has a human half-life of 15 to 80 hours, much longer than the parent filgrastim (3–4 hours).[21][20]

Pegfilgrastim was approved for medical use in the United States in January 2002, in the European Union in August 2002, and in Australia in September 2002.[19][17][22][23][24] It is on the World Health Organization's List of Essential Medicines.[25]

Medical uses

Pegfilgrastim is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in people with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia; and to increase survival in people acutely exposed to myelosuppressive doses of radiation (hematopoietic subsyndrome of acute radiation syndrome).[16][26][27]
