ProMetic's PBI-4050 Anti-Fibrotic Effect Confirmed on Human Kidney Cells

LAVAL, QUEBEC--(Jun 1, 2015) - ProMetic Life Sciences Inc. (TSX:PLI) (OTCQX:PFSCF), ("ProMetic" or the "Corporation") presented new data at the European Renal Association (ERA) annual meeting in London, UK. The new data confirms that PBI-4050's anti-fibrotic effect demonstrated in the kidney in several different animal models has been successfully reproduced in human kidney cell lines during in vitro experiments.

The data presented at the ERA annual meeting summarizes the effect of PBI-4050 on Normal Human Dermal Fibroblasts ("NHDF") and Human Epithelial Proximal Tubule Cells (HK-2) ("human kidney cells") in in vitro experiments designed to simulate fibrosis. PBI-4050 was found to regulate the pro-fibrotic growth factors and the remodeling enzymes in both the NHDF and human kidney cells in the same manner as observed in animals.

"This is very important data because it confirms that the anti-fibrotic mechanism of action of PBI-4050 is similar in humans and in animals", commented Dr. John Moran, Chief Medical Officer of ProMetic. "These results provide further support for our belief that the efficacy of PBI-4050 demonstrated in multiple preclinical models will translate into clinical benefit in patients suffering from fibrotic diseases such as idiopathic pulmonary fibrosis or chronic kidney disease associated with diabetes".

Dr. Lyne Gagnon, Head of R & D, Preclinical Research at ProMetic confirmed: "Our data correlates the regulation activity of PBI-4050 on key fibrotic biomarkers and the resulting improved kidney function. In fact, we have observed this in all major organs including the pancreas, liver, lungs and heart".

PBI-4050 is currently in phase II clinical trials in patients suffering from IPF, and in patients with metabolic syndrome and type 2 diabetes. ProMetic will commence a phase II clinical trial in the second half of 2015 with PBI-4050 in patients suffering from chronic kidney disease associated with diabetes.

More on PBI-4050

PBI-4050 is an orally active lead drug candidate with excellent safety and efficacy profiles confirmed in several in vivo experiments targeting fibrosis. Fibrosis is a very complex process by which continuing inflammation causes vital organs to lose their function as normal tissue is replaced by fibrotic scar tissue. The proof of concept data generated to date confirms our lead drug candidates' anti-fibrotic activity in several key organs including the kidneys, the heart, the lungs and the liver.
