NCIt synonyms : Recombinant Dimeric G-CSF Fusion Protein F627; Rh G-CSF Fc Fusion Protein F-627;
NCIt definition : A recombinant dimeric fusion peptide of the human granulocyte colony-stimulating factor
(G-CSF; filgrastim), with immunomodulating and hematopoietic activities. Efbemalenograstim
alfa binds to the cell surface G-CSF receptors (G-CSFRs) inducing receptor dimerization
and activation of signaling cascades such as the Jak-STAT and mitogen-activated protein
kinase pathways. This stimulates neutrophil progenitor proliferation and differentiation.
Compared to other preparations of monomer recombinant G-CSF, dimeric filgrastim may
allow for stronger activation of G-CSFRs and a faster myeloid precursor response thus
enhancing neutrophil recovery upon myelosuppressive therapy.;
