Spectral announces publication demonstrating Toraymyxin(TM) significantly reduces mortality from sepsis in prospective controlled trial
Date:6/18/2009

TORONTO, June 18 /PRNewswire-FirstCall/ - Spectral Diagnostics Inc. (TSX:SDI), a company developing products for the treatment of sepsis, today announced that findings demonstrating the Toraymyxin(TM) cartridge, a blood purification device that absorbs endotoxin from the bloodstream, when added to conventional therapy, significantly improved hemodynamics and organ dysfunction and reduced 28-day mortality in patients with severe sepsis and septic shock. The article entitled "Early Use of Polymyxin B Hemoperfusion in Abdominal Septic Shock: The EUPHAS Randomized Controlled Trial," was published in the Journal of the American Medical Association (JAMA). Spectral has exclusive rights to Toraymyxin(TM) in the United States and plans to initiate a trial in the U.S. in the latter half of 2009.

"The degree of reduction in mortality demonstrated by Toraymyxin(TM) in the EUPHAS trial is an unprecedented result for sepsis therapies and indicates that this product has the potential to fulfill an unmet need for the approximately 100,000 patients that develop severe sepsis or septic shock in the U.S. each year," said Dr. Paul Walker, President and CEO of Spectral Diagnostics. "Our Endotoxin Activity Assay (EAA(TM)) has the ability to identify patients who could benefit from this therapy and monitor its effect. Together, this diagnostic and therapeutic have the potential to provide a more effective treatment for patients with severe sepsis and septic shock caused by endotoxemia."

The objective of this study was to determine whether Toraymyxin(TM), when added to conventional medical therapy, improves clinical outcomes and mortality compared with conventional therapy alone, in a targeted patient population with severe sepsis and/or septic shock associated with intra-abdominal infections.

    -   28 day mortality was 32% (11/34 patients) in the Toraymyxin(TM) group
        and 53% (16/30 patients) in the conventional therapy group.
    -   Mean Arterial Pressure (MAP) increased (76 to 84 mm Hg;
        P = 0.001) in the Toraymyxin(TM) group but not in the
        conventional therapy group (MAP, 74 to 77 mm Hg; P =
        0.37).
    -   Vasopressor requirement decreased (inotropic score, 29.9 to 6.8; P
        (less than) 0.001) at 72 hours in the Toraymyxin(TM) group but not in
        the conventional therapy group (inotropic score, 28.6 to 22.4; P
        = 0.14).
    -   Sequential Organ Failure Assessment scores improved in the Toraymyxin
        (TM) group but not in the conventional therapy group (change in SOFA,
        -3.4 vs -0.1; P (less than) 0.001).

    About Spectral Diagnostics

Spectral is a leader in the battle against sepsis. Spectral's lead product is its Endotoxin Activity Assay (EAA(TM)), the only FDA cleared assay for the measurement of endotoxin. With the growing awareness for the role of endotoxemia in sepsis and the increasing number of therapies being developed for this indication, Spectral is well-positioned to drive the adoption of the EAA(TM), which can be used to identify patients, enable therapeutics and monitor treatment. In March 2009, Spectral obtained the exclusive development and commercial rights in the U.S. for Toraymyxin(TM), a therapeutic for the treatment of sepsis that removes endotoxin from the bloodstream. Spectral will seek FDA approval for Toraymyxin(TM) and intends to commercialize the product together with EAA(TM). Spectral is listed on TSX under the symbol SDI.
