ACTION AND CLINICAL PHARMACOLOGY GENERAL STEMGEN ® (ancestim) is recombinant-methionyl human stem cell factor (r- metHuSCF), a homologue of endogenous human stem cell factor (SCF), produced by recombinant DNA technology. 1 Hematopoietic growth factors, including SCF, are glycoproteins, which act on hematopoietic cells by binding to specific cell surface receptors and stimulating proliferation, differentiation, commitment, and/or functional activation. Receptors for SCF are found on a range of early to more mature hematopoietic progenitor cells, as well as mast cells, melanocytes, and germ cells. Endogenous SCF is a multilineage hematopoietic growth factor which is produced by bone marrow fibroblasts. 2,3 In humans, the serum concentration of soluble SCF averages 3.3 ± 1.1 ng/mL. 2,3 PHARMACOLOGIC EFFECTS OF STEMGEN ® (ANCESTIM) IN COMBINATION WITH NEUPOGEN ® (FILGRASTIM) In phase 1/2 studies involving 367 patients with breast cancer, non-Hodgkin’s lymphoma, and ovarian cancer, STEMGEN ® administration over a dose range of 5 to 25 mcg/kg/day in combination with a fixed dose of NEUPOGEN ® resulted in a dose-dependent increase in circulating peripheral blood progenitor cells (PBPC) compared to NEUPOGEN ® alone. 4 The PBPCs included CD34 + cells, granulocyte macrophage colony-forming units (CFU-GM), and erythroid burst- forming units (BFU-E). For patients receiving the cytokine combination, this 3 increase in circulating PBPC resu Llegiu el document complet
