Positive Clinical Data for PBI-1402 Presented at the Annual Congress of the European Hematology Association

MONTREAL, QUEBEC--(Marketwire - June 14, 2008) - ProMetic Life Sciences Inc. (TSX:PLI) ("ProMetic") today presented results on its orally-active PBI-1402 compound in clinical trial in patients with chemotherapy-induced anemia ("CIA") at the 13th Congress of the European Hematology Association held in Copenhagen, Denmark this week.

Dr. Lyne Gagnon, ProMetic's Director R&D, Biology, presented data on PBI-1402 in a poster entitled "PBI-1402 increases hemoglobin level and red blood cell count in chemotherapy-induced anemia". Results demonstrated that a once daily oral treatment of PBI-1402 induces a significant increase in hemoglobin ("Hb") level, red blood cell ("RBC") count and hematocrit ("Ht") in CIA patients. Furthermore, results suggest that PBI-1402 can reduce the need for RBC transfusion, since only 6% of patients in the clinical trial required transfusion.

"Subsequent positive data compiled from the 28 patients having completed the PBI-1402 CIA clinical trial include the fact that 26 of these patients did not require RBC transfusions while maintaining their full chemotherapy regimen. This data further supports that PBI-1402's current performance is in line with the Food and Drug Administration's ("FDA") recommendation of reducing patient need for RBC transfusions," states Mr. Pierre Laurin, ProMetic's President and Chief Executive Officer. "Additionally, PBI-1402 offers the added advantage of oral dosing which allows for a convenient management of anemia without interference with other treatments received by the CIA patients."

In the March 13, 2008 briefing document, the FDA's Oncologic Drugs Advisory Committee emphasized that the primary objective of treating CIA patients with erythropoiesis-stimulating agents ("ESAs") as being the ability to reduce the need for RBC transfusions. Approximately 50% of anemic patients receiving chemotherapy require RBC transfusions, and 20%-25% of patients treated with ESAs still require RBC transfusions.
