NCIt definition : A biosimilar of pegfilgrastim, a long-acting pegylated form of recombinant human granulocyte
colony-stimulating factor (G-CSF) filgrastim, with hematopoietic activity. In a similar
manner to G-CSF, pegfilgrastim biosimilar LA-EP2006 binds to and activates specific
cell surface receptors, stimulating neutrophil progenitor proliferation and differentiation
and selected neutrophil functions. Therefore, this agent may prevent the incidence
and shorten the duration of chemotherapy-induced neutropenia. Conjugation of the cytokine
with a branched polyethylene glycol molecule significantly increases this agent's
therapeutic half-life compared to filgrastim.;
