Dasatinib

Dasatinib, previously known as BMS-354825, is a cancer drug produced by Bristol-Myers Squibb and sold under the trade name Sprycel. Dasatinib is an oral Bcr-Abl tyrosine kinase inhibitor (inhibits the "Philadelphia chromosome") and Src family tyrosine kinase inhibitor approved for first line use in patients with chronic myelogenous leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). It is being evaluated for use in numerous other cancers, including advanced prostate cancer. Dasatinib was developed by collaboration of Bristol-Myers Squibb and Otsuka Pharmaceutical Co., Ltd.

Efficacy

In a Phase I dose escalation study published in June 2006, dasatinib was tested in patients who were resistant to or who could not tolerate imatinib. Complete hematological responses were seen in 37 of 40 patients with chronic-phase CML. Major hematologic responses were seen in 31 of 44 patients with accelerated-phase CML, CML in blast crisis, or Ph+ ALL.
