ATC Group: L03AA Colony stimulating factors

Efbemalenograstim alfa is a colony-stimulating factor that acts on hematopoietic cells by binding to specific cell surface receptors, thereby stimulating proliferation, differentiation, commitment, and end cell functional activation.

Eflapegrastim-xnst is a recombinant human granulocyte growth factor that binds to G-CSF receptors on myeloid progenitor cells and neutrophils, triggering signaling pathways that control cell differentiation, proliferation, migration and survival. Eflapegrastim-xnst has been shown to elevate neutrophil counts in healthy subjects and in cancer patients.

Filgrastim causes marked increases in peripheral blood neutrophil counts within 24 hours, with minor increases in monocytes.

Lenograstim belongs to the cytokine group of biologically active proteins which regulate cell differentiation and cell growth. Lenograstim induces a marked increase in peripheral blood neutrophil counts within 24 hours of administration.

Lipegfilgrastim is a sustained duration form of filgrastim due to decreased renal clearance. Lipegfilgrastim binds to human the G-CSF receptor like filgrastim and pegfilgrastim. Human G-CSF is a glycoprotein that regulates the production and release of functional neutrophils from the bone marrow.

Pegfilgrastim is a sustained duration form of filgrastim due to decreased renal clearance. Pegfilgrastim and filgrastim have been shown to have identical modes of action, causing a marked increase in peripheral blood neutrophil counts within 24 hours, with minor increases in monocytes and/or lymphocytes.

Sargramostim is a recombinant human granulocyte-macrophage colony stimulating factor (rhu GM-CSF) produced by recombinant DNA technology in a yeast (S. cerevisiae) expression system. GM-CSF is a hematopoietic growth factor which induces partially committed progenitor cells to divide and differentiate in the granulocyte-macrophage pathways which include neutrophils, monocytes/macrophages and myeloid-derived dendritic cells.
