FDA Advisory Committee To Consider U.S. Navy's Proposed 'RESUS' Trauma Trial At July 2006 Meeting

CAMBRIDGE, Mass., May 26 /PRNewswire-FirstCall/ -- Biopure Corporation announced today that it has been notified by the Food and Drug Administration (FDA) that the FDA's Blood Products Advisory Committee will meet on July 14, 2006 to discuss the Navy's proposed RESUS clinical trial of the company's investigational oxygen therapeutic Hemopure(R) [hemoglobin glutamer - 250 (bovine)] for out-of-hospital treatment of hemorrhagic shock resulting from traumatic injury. FDA has invited the Naval Medical Research Center (NMRC) and Biopure to present at the meeting. As previously announced, NMRC's investigational new drug application (IND) for RESUS is on clinical hold at FDA.

"We believe that the product holds promise as an emergency pre-hospital treatment until patients can receive blood or other standard treatment at a hospital, and we look forward to presenting our data," said Biopure Chairman and CEO Zafiris G. Zafirelis.

The Blood Products Advisory Committee reviews and evaluates available data concerning the safety, effectiveness, and appropriate use of blood products derived from blood and serum or biotechnology which are intended for use in the diagnosis, prevention, or treatment of human diseases, and, as required, any other product for which FDA has regulatory responsibility, and advises the Commissioner of Food and Drugs of its findings regarding the safety, effectiveness, and labeling of the products, on clinical and laboratory studies involving such products, on the affirmation or revocation of biological product licenses, and on the quality and relevance of FDA's research program which provides the scientific support for regulating these agents.

In order for the proposed RESUS trial to proceed, FDA must lift the clinical hold and the Department of Defense and the institutional review boards of participating hospitals in the communities where the study would take place must provide final authorization.
