LAVAL, QUEBEC, CANADA, – November 4, 2013 – ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF), ("ProMetic" or the "Corporation") presented new preclinical data at the 2013 annual meeting of the American Association for the Study of Liver Diseases (AASLD) held in Washington on November 2-4 supporting the claims that PBI-4050 anti-fibrotic activity could also be used to address various liver conditions such as nonalcoholic steatohepatitis ("NASH"), a condition affecting 2% to 5% of Americans.
PBI-4050's favorable effect in reducing the progression of fibrosis in liver was demonstrated in two
different "gold-standard" animal models. The first is a diabetic mouse model in which the animals develop liversteatosis. Similar to what is observed in humans, the untreated animals accumulate fat in the liver causing inflammation and leading to permanent damage and scarring, and reducing the ability for the liver to function properly. Diabetic mice treated with PBI-4050 had a significant reduction of liver lesions and steatosis measured by histology as well as a significant reduction in key biomarkers such as including TGFβ-1, Collagen 1, MMP2 and TIMP-1.
In a second model, the liver fibrosis is induced by chronic administration of carbon tetrachloride (CCL4), a chemical which at high chronic dose, causes irreversible damage to the liver and the kidney. Again animals
treated with PBI-4050 displayed a significant reduction of liver lesions as evidenced by histology and relevant biomarkers.
"These results clearly indicates that PBI-4050 anti-fibrotic activity is at the core of the fibrosis regulation pathway affecting multiple organs and tissues", stated Dr. Lyne Gagnon, Head of Biology & Immunology at ProMetic.
Dr. John Moran, a member of ProMetic's Board of Directors stated "Since patients with diabetes are more
likely to develop complications affecting the kidneys and liver, the positive effects observed with PBI-4050 in multiple challenging animal models bodes well for its potential use in this patient population."

More on NASH
Nonalcoholic steatohepatitis or NASH is a common, often "silent" liver disease. It resembles alcoholic liver disease, but occurs in people who drink little or no alcohol. The major feature in NASH is fat in the liver, along with inflammation and damage. Most people with NASH feel well and are not aware that they have a
liver problem. Nevertheless, NASH can be severe and can lead to cirrhosis, in which the liver is permanently damaged and scarred and no longer able to work properly. NASH affects 2 to 5 percent of Americans
