MONTREAL, QUEBEC--(Marketwire - June 9, 2010) -

• Comparative data with erythropoietin in various cancer models

• Clinical data in oncology patients developing anemia under chemotherapy

ProMetic Life Sciences Inc. (TSX:PLI) ("ProMetic") will present data on its orally-active PBI-1402 compound at the 15th Congress of the European Hematology Association held in Barcelona, Spain, June 9 – 13, 2010. Clinical and preclinical results will be presented about the management of side effects induced by chemotherapy and the treatment of certain cancers such as lung and pancreatic cancers, and certain forms of leukemia.

In addition, an oral presentation will be made regarding the positive clinical data generated in patients that developed anemia as a result of their chemotherapy.

PBI-1402 is a first-in-class candidate drug with clinical data that demonstrated a reduction in the need for blood transfusions in chemotherapy-induced anemic patients. Furthermore, the trial indicated that the level of hemoglobin and red blood cells never exceeded recommended levels even when the drug was used at high dose. This, combined with anti-cancer activity demonstrated in numerous cancer models, supports the potential use of PBI-1402 to address unmet medical needs in oncology.

"The data accumulated through our latest research distinguishes PBI-1402 from all other ESAs and has suggested additional applications. Furthermore, the identification of follow-on analogues resulted from this work," stated Mr. Pierre Laurin, ProMetic's President and Chief Executive Officer. "Not only did the findings allow us to define clear regulatory pathways for PBI-1402; our scientists have also discovered new and proprietary compounds that regulate fibrosis via a novel mechanism of action. Fibrosis is part of the inflammatory process that leads to a loss of functionality in vital organs such as kidney, heart, liver and lungs in certain chronic diseases that affects hundreds of millions of patients. This is exciting because the understanding of how PBI-1402 works has considerably expanded the value of the drug portfolio," added Mr. Laurin.

Among the studies to be presented:

June 11, 2010 at 17:45 (CEST) - Poster session

"Comparative studies between erythropoietin (EPO) and PBI-1402, a new erythropoiesis-stimulating agent (ESA), on murine cancer models"

June 13, 2010, at 08:30 (CEST) - Oral presentation

"PBI-1402: A first-in-class ESA which reduces the need for blood transfusion in chemotherapy-induced anemic patients"
