( - Phase II Results Published in the Jou...)Study Shows Ixabepilone Demonstrated Clear Activity in Patients,with Metastatic Breast Cancer Resistant to Anthracycline, Taxane,,and Capecitabine,Health

NEW YORK, July 06, 2007 /PRNewswire-FirstCall/ -- Results from a Phase II study - which will be published in the August 10, 2007 issue of the Journal of Clinical Oncology (JCO) and are now available as an Early Release Article at www.jco.org - demonstrate that ixabepilone, a Bristol-Myers Squibb Company investigational compound, has activity in patients with metastatic breast cancer whose tumors were resistant to three types of standard chemotherapy (anthracycline, taxane, and capecitabine). Currently, there are few proven treatment options available to patients with breast cancer whose disease has rapidly progressed through or whose disease is not responding to prior treatment with approved chemotherapies. This study was one of five Phase II ixabepilone studies published in this issue of JCO, including three additional studies in metastatic breast cancer and one in non-small cell lung cancer.

"Drug resistance is a major concern in treating patients with advanced disease," said Renzo Canetta, vice president, Oncology Global Clinical Research, Bristol-Myers Squibb. "The results of this study are important as they provide valuable information about this investigational compound and its potential in patients with advanced breast cancer that is no longer responding to any of the current U.S. approved chemotherapy treatments."

The 126 patients enrolled in the single-arm Phase II study (CA163081) had heavily pretreated, advanced metastatic breast cancer, which had progressed through three prior therapies (anthracycline, taxane and capecitabine). The primary endpoint was objective response rate, which is an assessment of the response to treatment as determined by the independent radiology facility (IRF). Secondary efficacy endpoints included duration of response, time to response, progres
