FDA Panel Recommends Navy's Proposed 'RESUS' Phase IIb/III Trauma Trial Not Proceed as Designed; Suggests Phase II Study CAMBRIDGE, Mass., Dec. 15 -- Biopure Corporation (Nasdaq: BPUR - News) announced today that the Food and Drug Administration's (FDA) Blood Products Advisory Committee voted 11 to 8, with one abstention, to recommend against proceeding with the Navy's proposed Phase IIb/III, 1100-patient study of Biopure's oxygen therapeutic HemopureÂ® [hemoglobin glutamer - 250 (bovine)] for the pre-hospital treatment of hemorrhagic shock resulting from traumatic injury. In view of the product's potential benefit in this patient population, committee members suggested that a pre-hospital Phase II/IIb study be designed to provide both safety and efficacy data in a smaller patient population. The recommendation, which is not binding on the FDA, came after a day-long hearing yesterday at which the Naval Medical Research Center (NMRC), which is sponsoring RESUS, and the FDA explained the study's design and discussed preclinical and clinical data. During its deliberations, the committee questioned whether existing data justify a Phase III trial to be conducted under the federal regulation (21 CFR 50.24) allowing for exception to informed consent in patients who are unable to provide adequate consent given the nature of their injuries. "Although the committee advised against RESUS moving forward, we view its comments today as constructive criticism and generally supportive of the product's development for the emergency pre-hospital treatment of trauma patients," said Biopure Chairman and CEO Zafirelis G. Zafirelis. Biopure Corporation Biopure Corporation develops, manufactures and markets pharmaceuticals, called oxygen therapeutics, that are intravenously administered to deliver oxygen to the body's tissues. HemopureÂ® [hemoglobin glutamer - 250 (bovine)], or HBOC-201, is approved for sale in South Africa for the treatment of surgical patients who are acutely anemic. Biopure has applied in the United Kingdom for regulatory approval of a proposed orthopedic surgical anemia indication. The company is developing Hemopure for a potential indication in cardiovascular ischemia, in addition to supporting the U.S. Navy's government-funded efforts to develop a potential out-of-hospital trauma indication. Biopure's veterinary product OxyglobinÂ® [hemoglobin glutamer - 200 (bovine)], or HBOC-301, the only oxygen therapeutic approved by the U.S. Food and Drug Administration and the European Commission, is indicated for the treatment of anemia in dogs.
