Pegfilgrastim is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (GCSF) analog filgrastim. It serves to stimulate the level of white blood cells (neutrophils).[2]
Pegfilgrastim treatment can be used to stimulate bone marrow to produce more neutrophils to fight infection in patients undergoing chemotherapy.[3]
Pegfilgrastim has a human half-life of 15 to 80 hours, much longer than the parent filgrastim (3–4 hours).[4][3]
In the United States as of 2015 the branded form costs between $5,327 and $8,191 USD a dose.[5]
Biosimilars
In July 2016 the US FDA rejected a biosimilar application from Sandoz.[6]
In 2016 Coherus BioSciences is running clinical studies on its own pegfilgrastim biosimilar CHS-1701.[6]
