Origines de la résistance au traitement par imatinib mésylate : un exemple riche d’enseignements

Abstract

For drug development and pharmaceutical research, targeting the molecular abnormalities is considered as a new challenge. A number of diseases including cancer are linked to perturbation of tyrosine kinase (TK). Imatinib (Glivec® or Gleevec®, Novartis), the most potent inhibitor of c-abl TK, was recently developed. This molecule has been approved in the treatment of chronic myeloid leukemia (CML). However, emergence of clinical resistance regarding a low rate of CML patients leads to intensive research. In the current article, we discuss the data and the mechanism of the resistance phenomenon. This review illustrates the important requirement to transfer back the information from patient to laboratory in order to improve future drug design.
