    Biopure Receives FDA Response to Hemopure(R) Marketing Application

    CAMBRIDGE, Mass., Aug. 1 /PRNewswire-FirstCall/ -- Biopure Corporation (Nasdaq:
    BPUR) announced today that the U.S. Food and Drug Administration (FDA) has
    completed its review of the company's biologic license application (BLA) for
    Hemopure(R) [hemoglobin glutamer - 250 (bovine)] and issued a letter requesting
    additional information. The letter focuses primarily on clarification of clinical and
    preclinical data and includes some comments on labeling. It does not request additional
    clinical trials. Biopure has applied to market Hemopure in the United States for the
    treatment of acutely anemic adult patients undergoing orthopedic surgery and for the
    elimination or reduction of red blood cell transfusions in these patients.

    With 30 days remaining in the original BLA review cycle, the issuance of the letter has
    suspended the FDA review clock until Biopure submits a complete response.

    "We're encouraged that the FDA has finished its review and provided comprehensive
    feedback in advance of the formal action due date. By maintaining thirty days on the
    review clock, the FDA is encouraging us to work with them to complete the approval
    process as quickly as possible," said Biopure President and CEO Thomas A. Moore.
    "We'll work with the Agency to address the remaining questions and will provide our
    answers as expeditiously as possible."

    Anemia is a shortage of RBCs in the body that can create an oxygen deficit and lead to
    cell damage, organ dysfunction or, in severe cases, death. Acute anemia, usually
    caused by blood loss, is the primary indication for a RBC transfusion. In 1999,
    approximately 1.4 million RBC units were transfused in 500,000 high blood loss
    orthopedic surgical procedures.* These statistics are expected to increase as the
    population ages.

    Hemopure is an oxygen therapeutic, or drug, consisting of chemically stabilized bovine
    hemoglobin formulated in a balanced salt solution. This stabilized, acellular hemoglobin
    circulates directly in plasma (the fluid part of blood) when administered intravenously,
    increasing oxygen delivery and diffusion. The product is compatible with all blood types,
    is stable for three years at room temperature (2 degrees to 30 degrees Celsius), and is
    purified through patented and proprietary techniques that are validated to remove
    potential contaminants.

    Biopure Corporation

    Biopure Corporation, headquartered in Cambridge, Mass., is the leading manufacturer
    and marketer of oxygen therapeutics, a new class of drugs that are intravenously
    administered to deliver oxygen to the body's tissues for the treatment of acute surgical
    anemia and other potential medical applications. Hemopure(R) [hemoglobin glutamer -
    200 (bovine)] is approved in South Africa for the treatment of acutely anemic surgical
    patients and for eliminating, delaying or reducing the need for red blood cell
    transfusion in these patients. The company's veterinary product, Oxyglobin(R)
    [hemoglobin glutamer - (200 bovine)], is a similar oxygen therapeutic approved in the
    United States and European Union for the treatment of anemia in dogs.

    Statements in this press release that are not strictly historical may be forward-looking
    statements. There can be no assurance that Biopure Corporation will be able to
    commercially develop its oxygen therapeutic products, that necessary regulatory
    approvals will be obtained, that anticipated milestones will be met in the expected
    timetable, that any clinical trials will be successful, or that any approved product will
    find market acceptance and be sold in the quantities anticipated. Actual results may
    differ from those projected in forward-looking statements due to risks and
    uncertainties that exist in the company's operations and business environment. These
    risks include, without limitation, the company's stage of product development, history
    of operating losses and accumulated deficits, and uncertainties and possible delays
    related to clinical trials, regulatory approvals, possible healthcare reform,
    manufacturing capacity, marketing, market acceptance, competition and the availability
    of sufficient financing to support operations. The company undertakes no obligation to

    I saw this today too. This is great news. Almost there. I wonder if the WTS will ever dedicate a QFR to hemoglobin substitutes?

    Suspicious of any new med treatment here, but...

    compatible with all blood types,

    how do they do this? isn't it still transgenic tissue? have they been able to render it inert so as not to trigger rejection/shock/immune issue? If it is inert, will it still carry oxygen?

    purified through patented and proprietary techniques that are validated to remove potential contaminants.

    does this include the prions and protiens implicated in bovine spongiform encephalopathy (mad cow disease) and other pathogens present in cow, undocumented (yet) in humans?

    and finally, in the legal disclaimers:

    Statements in this press release that are not strictly historical may be forward-looking statements. There can be no assurance that Biopure Corporation will be able to commercially develop its oxygen therapeutic products, (...)

    I'm still really skeptical of the treatment efficacy, though the potential is there. How quickly it comes to market is largely a matter of potential profits though. I wonder if there are any uninterested third party write-ups on these trials yet. Interesting subject...

    Odrade,

    how do they do this? isn't it still transgenic tissue? have they been able to render it inert so as not to trigger rejection/shock/immune issue? If it is inert, will it still carry oxygen?

    If my limited medical memory recalls correctly, the "typing" of blood is based on the shell of the actual red blood cell. The hemoglobin carried inside does not have this typing issue. There is something on the shell of the cell which determines if someone is A, B, AB, etc. A little searching on the web would probably give a better detailed description than I could give.

    Do we know for certain that the WTS will approve Hemopure transfusions?

    According to the WTS, it is a conscience decision whether a JW accepts products made from the four major blood components.

    ***

    w00 6/15 p. 29 Questions From Readers ***

    Today, most transfusions are not of whole blood but of one of its primary components: (1) red cells; (2) white cells; (3) platelets; (4) plasma (serum), the fluid part.

    Jehovah’s Witnesses hold that accepting whole blood or any of those four primary components violates God’s law.

    However, since blood can be processed beyond those primary components, questions arise about fractions derived from the primary blood components. How are such fractions used, and what should a Christian consider when deciding on them?

    Plasma also carries such proteins as albumin, clotting factors, and antibodies to fight diseases.

    Or if someone is exposed to certain diseases, doctors might prescribe injections of gamma globulin, extracted from the blood plasma of people who already had immunity

    Just as blood plasma can be a source of various fractions, the other primary components (red cells, white cells, platelets) can be processed to isolate smaller parts.

    And other medicines are coming along that involve (at least initially) extracts from blood components (HEMOGLOBIN-BASED PRODUCTS SUCH AS HEMOPURE my comments). Such therapies are not transfusions of those primary components; they usually involve parts or fractions thereof. Should Christians accept these fractions in medical treatment? We cannot say. The Bible does not give details, so a Christian must make his own conscientious decision before God.

    The above material shows that Jehovah’s Witnesses refuse transfusions of both whole blood and its primary blood components. The Bible directs Christians to ‘abstain from things sacrificed to idols and from blood and from fornication.’ (Acts 15:29) Beyond that, when it comes to fractions of any of the primary components, each Christian, after careful and prayerful meditation, must conscientiously decide for himself.

    Why is it I get a vision of a bunch of Talmudic scholars splitting hairs over issues that really are never addressed in Scripture?
