Ambit Biosciences presents data evaluating FLT3 inhibitor in AML at the 51st ASH meeting

Ambit Biosciences Corporation announced today that there will be multiple presentations evaluating AC220, a novel second generation FLT3 inhibitor, in AML at the 51st American Society of Hematology Annual Meeting (ASH) to be held in New Orleans, LA ,December 5-8, 2009. An oral presentation will highlight results from an ongoing clinical Phase I monotherapy safety study in adults with acute myeloid leukemia (AML). Additionally, non-clinical data will be presented evaluating the effect of AC220 monotherapy and in combination with chemotherapy.

"AML continues to be a disease with a significant unmet medical need and new therapies are urgently needed," said M. Scott Salka, Chief Executive Officer of Ambit Biosciences. "The Phase I clinical data we've seen for AC220 in AML are extremely encouraging and supports the further development of this highly selective second-generation FLT3 inhibitor."

Data Highlights for AC220 include:
