What Stemgen ® is used for Stemgen ® is a man-made form of a naturally-occurring substance which stimulates the growth of certain blood cells called progenitor cells. These cells are the very early forms of blood cells that mature to become red blood cells, white blood cells and platelets. Stemgen ® is given with another medicine called Neupogen ® as an injection under the skin. This increases the number of progenitor cells in the blood (peripheral blood progenitor cells, PBPCs). These cells are then collected from the blood, stored and given back to you after chemotherapy. This procedure is called a PBPC transplant and helps recovery of blood cells after treatment. There is limited experience with Stemgen ® in children. Your doctor will discuss the risks and benefits of Read the complete document
Stemgen (ancestim) REGISTERED PRODUCT INFORMATION Page 1 of 13 Invida Australia Pty Limited RBQSYD-STEMGENRegPI11MAR10- VER2 NAME OF THE DRUG Ancestim is a human stem cell factor (SCF) produced by recombinant DNA technology. STEMGEN is the Biovitrum AB (publ) trademark for ancestim (recombinant methionyl human stem cell factor, r-metHuSCF). DESCRIPTION STEMGEN is a 166 amino acid protein produced by _Escherichia coli_ (_E. coli_) bacteria into which a gene has been inserted for soluble human stem cell factor. STEMGEN has a monomeric molecular weight of approximately 18,500 daltons and normally exists as a noncovalently associated dimer. The protein has an amino acid sequence that is identical to the natural sequence predicted from human DNA sequence analysis, except for the addition of an N-terminal methionine retained after expression in _E. coli_. Because STEMGEN is produced in _E. coli_, the product is nonglycosylated. STEMGEN is a sterile, white, preservative-free, lyophilised powder for reconstitution and administration as a subcutaneous (SC) injection. Each single-use vial of STEMGEN contains 1.875 mg of ancestim at a specific activity of 0.84 to 1.8 x 10 6 U/mg (as measured by a cell mitogenesis assay). Vials of STEMGEN are reconstituted with 1.2 mL of sterile Water for Injections to yield an ancestim concentration of 1500 µg/mL. Reconstituted STEMGEN is a sterile aqueous solution containing 4.5% mannitol and 0.5% sucrose buffered at pH 6.0 with 5 mM glutamic acid and 10 mM histidine. PHARMACOLOGY PHARMACOKINETICS GENERAL The pharmacokinetics of STEMGEN is dose linear in the range of 5 to 30 µg/kg in bo Read the complete document
