ProMetic Updates Hematology and Cancer Programs: "First in Class" New Compounds in Preclinical Development

- PBI-3941 for neutropenia - PBI-1737 for prostate cancer

MONTREAL, QUEBEC--(CCNMatthews - Feb. 1, 2007) - ProMetic Life Sciences Inc. (TSX:PLI) ("ProMetic") today provided an update on its therapeutic unit, ProMetic BioSciences Inc., which focuses on the development of synthetic drugs in hematology and cancer. This work has given rise to a number of compounds from which the latest compounds, PBI-1737 and PBI-3941, have been selected respectively for preclinical testing in cancer and neutropenia.

Pierre Laurin, President and Chief Executive Officer of ProMetic stated, "Our objective is to create a pipeline composed of compounds with the potential to produce drugs for treating cancer and hematological disorders. I am pleased to say that we have continued to test and discover more compounds, which expands our knowledge base and augments our pipeline."

HEMATOLOGY PROGRAM

ProMetic's hematology program is focused on hematopoiesis. PBI-1402 is ProMetic's lead clinical compound in hematopoiesis; it targets anemia caused by chemotherapy and renal diseases by promoting the formation of red blood cells from bone marrow.

The mechanism of action is distinct from the current drug of choice for the treatment of anemia, EPO. PBI-1402 does not bind to the same cell surface receptor as EPO, and therefore offers three potential uses for PBI-1402 to treat anemic patients: as a stand alone treatment, in patients not responsive to EPO and in combination with EPO.

PBI-1402 is being tested in three Phase Ib/II trials for anemia. They include two chemotherapy induced anemia trials in Canada and Europe and recently, the Company received regulatory approval in Canada to treat anemic patients with Chronic Kidney Disease.

ProMetic anticipates that it will develop a next generation version of PBI-1402 for anemia, which is intended to exploit different activities of the lead drug candidate.

PBI-3941 is ProMetic's lead preclinical hematopoiesis compound. It targets neutropenia, a condition where white blood cell counts are lower than normal. Mr. Laurin commented, "In animal studies, PBI-3941 demonstrated an increase in neutrophil count, thus confirming that ProMetic scientists have homed in on a new class of compounds that can provide the discovery of many 'first in class' drugs for various hematological disorders. These potential drugs have the advantage of reduced cost in comparison with recombinant protein drugs currently on the market."

CANCER PROGRAM

ProMetic's cancer program is focused on synthetic compounds which target a wide range of cancers. PBI-1393 is ProMetic's lead clinical compound in cancer. It functions as an activator of cytotoxic T-lymphocytes (CTLs) and will soon be tested in a Phase Ib/II trial for advanced cervical cancer. In addition to cervical cancer, ProMetic scientists believe that PBI-1393 will be a valuable drug for the treatment of other cancers, such as metastatic melanoma, breast, colon and pancreatic cancers, which are sensitive to the action of CTLs.

Other compounds in ProMetic's preclinical cancer pipeline include: PBI-1737 for prostate cancer; PBI-1668 for breast and lung cancer and PBI-1308 for acute leukemia. Mr. Laurin said, "This is a very encouraging discovery program which has led to a diversified pipeline of compounds for the treatment of cancer and hematological disorders."
