DASATINIB . FDA approves additional medical indication for Sprycel

The U.S. Food and Drug Administration today approved a new indication for Sprycel (dasatinib) for the treatment of a rare blood cancer when it is first diagnosed. The cancer, called Philadelphia chromosome positive chronic phase chronic myeloid leukemia (Ph+ CP-CML), is a slowly progressing blood and bone marrow disease linked to a genetic abnormality.

Sprycel, an oral kinase inhibitor, is believed to inhibit the activity of certain proteins responsible for the growth of cancer cells. The action allows bone marrow to begin reproducing normal red and white blood cells.

In June 2006, the FDA granted accelerated approval for Sprycel to treat adults with CP-CML with resistant disease or who were intolerant to prior therapy, including Gleevec (imatinib). The agency converted Sprycel to a regular approval in May 2009, after 24-month follow-up data from earlier clinical studies confirmed the treatment’s safety and effectiveness.

Other FDA-approved drugs to treat various forms of CML include Gleevec, approved in May 2001, and Tasigna (nilotinib), approved in October 2007.
