Neupogen for Gleevec in CML

Senior man getting his heart beat checked by a doctor


Many chemotherapeutic drugs cause neutropenia and guidelines now uniformly recommend G-CSF(granulocyte growth stimulating factors) prophylactically and therapeutically for chemotherapy. However, non-chemo drugs can also cause neutropenia. Among them are bcr-abl directed drugs used for CML, such as Gleevec. Depending on the stage, up to 70% of the patients treated with imatinib for CML experience an NCI grade 3 or 4 neutropenia or thrombocytopenia during Imatinib therapy. A number of reprots indicate that Neupogen can overcome neutropenia, allowing maintenence of dose and schedule of imatinib. NCCN in version 2.2013 recommends GSCF in combination with imatinib in patients with refractory neutropenia. In Asia beramine is being investigated for this problem.
