About G-CSF and Neutropenia

G-CSF is prescribed to stimulate the production of neutrophils, and is approved for sale in major markets around the world for the treatment of neutropenia associated with myelosuppressive chemotherapy. Worldwide sales in the G-CSF category exceeded $4 billion in 2006. Neutropenia is a severe reduction in the number of neutrophils (mature white blood cells) in the circulating blood, commonly associated with cancer chemotherapy. Patients with neutropenia are at increased risk of developing serious infection. If not treated promptly, neutropenia can be life-threatening.
