Pegfilgrastim Provides Extended Duration for Managing Neutropenia


Pegfilgrastim (Neulasta—Amgen) has been approved to decrease the incidence of infection, as manifested by febrile neutropenia, in patients receiving chemotherapy. While it carries nearly the same indication as the company’s well-known filgrastim (Neupogen) colony-stimulating factor, the pegylated form of the drug has a longer half-life, which permits a single subcutaneous (SC) injection 24 hours after chemotherapy that will stimulate hematopoiesis for up to 14 days.
