European Medicines Evaluation Agency Grants Cell Therapeutics, Inc. Orphan Drug Designation for Pixantrone in Diffuse Large B-Cell Lymphoma (DLBCL)

SEATTLE, Dec. 21 /PRNewswire-FirstCall/ -- Cell Therapeutics, Inc. (“CTI”) announced today that the European Medicines Agency (EMEA) has granted pixantrone orphan drug designation for the treatment of DLBCL which accounts for about 80% of aggressive non-Hodgkin’s lymphoma. CTI expects to file the Marketing Authorization Application (MAA) in Europe for approval of pixantrone in mid-2010 and would be granted 10 year market exclusivity if it is approved. In the U.S., the Food & Drug Administration’s (FDA) Oncologic Drugs Advisory Committee (ODAC) plans to review the New Drug Application (NDA) for pixantrone for the treatment of relapsed/refractory aggressive non-Hodgkin’s lymphoma (NHL) on February 10, 2010. Pixantrone is a fast track designated product in the U.S. and is in review for approval by the FDA, with a Prescription Drug User Fee Act (PDUFA) date of April 23, 2010.

“Orphan drug designation for pixantrone in Europe demonstrates that there is clear unmet medical need for patients with DLBCL,” stated Craig W. Philips, President of CTI. “We will continue to work with the EMEA to move our application forward in Europe expeditiously as we prepare for potential commercial launch of pixantrone in the United States.”
