The oncoprotein Bcr-Abl drives aberrant downstream activity through trans-autophosphorylation of homo-oligomers in chronic myelogenous leukemia (CML).(1, 2) The formation of Bcr-Abl oligomers is achieved through the coiled-coil domain at the N-terminus of Bcr.(3, 4) We have previously reported a modified version of this coiled-coil domain, CCmut2, which(More)
In 2012, ponatinib (Iclusig(®)), an orally available pan-BCR-ABL tyrosine kinase inhibitor (TKI) developed by ARIAD Pharmaceuticals, Inc., was approved by the US Food and Drug Administration for use in resistant or intolerant chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL). Ponatinib is the only(More)
Targeted therapy of chronic myeloid leukemia (CML) is currently based on small-molecule inhibitors that directly bind the tyrosine kinase domain of BCR-ABL1. This strategy has generally been successful, but is subject to drug resistance because of point mutations in the kinase domain. Kinase activity requires transactivation of BCR-ABL1 following an(More)
1 recently reviewed the role of ponatinib in chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (Ph+ ALL), yet by the omission of an approved agent within the same class of drugs, provided an inaccurate summary of the current treatment landscape for CML. The authors discussed the evolution of tyrosine kinase(More)
