Pegfilgrastim, sold under the brand name Neulasta among others, is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (GCSF) analog filgrastim. [19] It serves to stimulate the production of white blood cells (neutrophils). [19] [21] Pegfilgrastim was developed by Amgen. [22]
Pegfilgrastim treatment can be used to stimulate bone marrow to produce more neutrophils to fight infection in patients undergoing chemotherapy. [23]
Pegfilgrastim has a human half-life of 15 to 80 hours, much longer than the parent filgrastim (3–4 hours). [24] [23]
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. [22] [20] [25] [26] [27] It is on the World Health Organization's List of Essential Medicines. [28]
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). [19] [29] [30]
In January 2025, the CHMP adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Dyrupeg, intended to shorten the duration of neutropenia and help prevent febrile neutropenia after cytotoxic chemotherapy. [31] The applicant for this medicinal product is CuraTeQ Biologics s.r.o. [31] Dyrupeg is a biosimilar medicinal product. [31] It is highly similar to the reference product Neulasta (pegfilgrastim), which was authorized in the EU in August 2002. [31]
