The discovery of imatinib, a signal transduction inhibitor, towards the end of the last century revolutionized the treatment of Chronic Myelogenous Leukemia (CML). Excellent haematological response as well as cytogenetic response made imatinib the standard of care in CML. It is and belongs to the category of EGFR-tyrosine kinase inhibitors.
