Imatinib (Gleevec) stunned the world with its high cure rate for chronic myeloid leukemia through the inhibition of tyrosine kinase Bcr-Abl. But, BCR-ABL mutations are a common cause of relapse during therapy. Working from imatinib's structure, researchers affiliated with Harvard University and Novartis developed AMN107, which is roughly 20 times as potent as imatinib and active against most imatinib-resistant Bcr-Abl mutations.
AMN107, now known as nilotinib (Tasigna), has completed Phase II clinical trials and is awaiting FDA and EU review as a new drug for chronic myeloid leukemia.
Brian Druker at Oregon Health & Science University in Portland says their use of imatinib's crystal structure in the design process was both interesting and...
