NCIt definition : A long-acting, pegylated, recombinant analog of the endogenous human granulocyte colony-stimulating
factor (G-CSF), with hematopoietic activity. Upon administration, mecapegfilgrastim
binds to and activates specific cell surface receptors and stimulates neutrophil progenitor
proliferation and differentiation, as well as selected neutrophil functions. This
may decrease the duration and incidence of chemotherapy-induced neutropenia (CIN).
Pegylation significantly increases the therapeutic half-life.;
