New Landmark Study Shows the Use of a BiovaxID Formulation Improves Disease Free survival in 80% of Patients Whose Cancer has Relapsed after Chemotherapy Administered With or Without Rituxan

TAMPA, Fla.--(HSMN NewsFeed)--Accentia Biopharmaceuticals Inc. (NASDAQ:ABPI ) reports that a new study by Dr. Susana Inoges and colleagues at the University of Navarra (Journal of the National Cancer Institute, 98:1292-1301, Sept 20, 2006) has shown that the administration of a BiovaxID(TM) formulation given to patients with relapsed Follicular Non-Hodgkins Lymphoma following chemotherapy, with or without concomitant Rituxan(TM)(1), can induce complete long-lasting remissions. Moreover, these second remissions are uniquely characterized by a duration that exceeds the duration of the first remission (P less than .0001). In the study, 80% of patients achieved an immune response to the Biovaxid formulation, and among these responders, the median time of complete tumor remission has not been reached after 33 months of mean follow-up.

In an accompanying editorial, Idiotype vaccination in follicular lymphoma: knocking on the doorway to a cure, Dr. Dan Longo, National Institutes of Health, characterized the results as "remarkable". "Among the 20 immunologic responders, the median duration of the second complete response has not been reached after nearly 3 years of follow-up (durations range from 20+ to 51+ months) and in every case, the second remissions have been longer than the initial remissions," commented Dr. Dan Longo. "By contrast, all five immunologic non-responders have relapsed, and in every case their second remission was shorter than their first. Long second remissions do not occur at this rate, even after high-dose therapy and autologous hematopoietic stem cell transplant" (Journal of the National Cancer Institute, 98:1263-1265, Sept 20 , 2006).
