ProMetic Further Confirms Performance of Prion Capture Resin at the Recovery of Biological Products Conference



    MONTREAL, June 25 /CNW Telbec/ - ProMetic Life Sciences Inc. (TSX:PLI)
("ProMetic") announced today that it has further confirmed the efficacy of the
prion capture resins developed by Pathogen Removal and Diagnostic Technologies
Inc. ("PRDT")' in the removal of prions from different solutions, including
mixtures of proteins containing high concentrations of specific proteins such
as 25% albumin and 3% immunoglobulin solutions without affecting the
concentration of the proteins. Plasma-derived albumin and immunoglobulin
proteins are commonly used as therapeutics. Furthermore, proteins such as
albumin are also regularly used as non-active stabilizing ingredients in the
formulation of biopharmaceutical products.
    "This has far reaching implications for the biopharmaceutical industry.
It offers the opportunity to provide an additional safety element by including
prion-depleted human blood-derived or animal-derived products in the
formulation and manufacture of some of these high-value therapeutics," stated
Mr. Pierre Laurin, ProMetic's President and Chief Executive Officer.
    In addition, the evaluation of PRDT resins established their ability to
efficiently remove infectious prion protein from whole human plasma, a complex
mixture of hundreds of different proteins, and demonstrated that the ligands
developed by PRDT targets the prion protein, and can bind that compound even
under the competition of several proteins, without significantly binding any
of the proteins vital for plasma.
    This corroboration of the PRDT resins' performance follows on the
June 10th announcement of Octopharma AG's recent implementation of PRDT's
prion removal resin into their manufacturing process of Octaplas(R). For
additional information on this announcement, please visit ProMetic's Newsroom
at www.prometic.com/en/news.htm.
    Dr. Patrick Gurgel, ProMetic's Senior Research Scientist addressed the
information on the PRDT resins in a poster titled "Removal of prion
infectivity from plasma-derived products" during the Recovery of Biological
Products 13 Conference held in Quebec City, Quebec from June 22 - 27, 2008.
The poster is available on ProMetic's website at
