06:30 EDT Thursday, September 26, 2013

LAVAL, QUEBEC--(Marketwired - Sept. 26, 2013) - ProMetic Life Sciences Inc. (TSX:PLI)(OTCQX:PFSCF), ("ProMetic" or the "Corporation") announced today that it has successfully completed the required GLP toxicology studies performed by a certified contract research organization confirming that Prometic's lead drug candidate, PBI-4050, is safe to advance into clinical trial stages.

"These positive results enable us to commence the clinical program to confirm safety in humans" stated Pierre Laurin, President and CEO of ProMetic who added "this is expected to be initially performed in healthy volunteers this year with enrollment of patients expected to begin in early 2014 to demonstrate efficacy".

Preclinical data on PBI-4050 confirms its potential as a novel therapy to inhibit inflammation and fibrosis which underlies progressive chronic renal diseases and pulmonary fibrosis as well as fibrosis in other organs such as the liver and the heart. Additional data will be presented at the forthcoming American Association for the Study of Liver Diseases (AASLD) annual meeting and at the American Society of Nephrology (ASN) annual meeting, both occurring in early November.

Dr. Lyne Gagnon, head of biology at ProMetic commented: "We are very pleased with the fact that the significant anti-fibrotic effect of PBI-4050 has been demonstrated in several different animal models. The new data to be presented at AASLD and ASN will further highlight that PBI-4050's anti-fibrotic activity is not only limited to the kidney and lungs but also extend to the liver and heart".

"ProMetic's investments in this comprehensive preclinical program yielding these positive results increase the probability that the significant therapeutic improvements observed in animals could translate into meaningful clinical benefits in humans" commented Dr John Moran, a member of ProMetic's Board of Directors. "The clinical program will be designed to leverage these findings and apply them to the appropriate patient population taking into account an optimal regulatory pathway ", added Dr Moran.

More on PBI-4050

PBI-4050 is an orally active lead drug candidates with efficacy and high safety profiles confirmed in several in vivo experiments targeting fibrosis. Fibrosis is a very complex process by which inflammation leads to the deposit of fibrous material to repair the damaged area and whereby vital organs gradually lose their functionality as normal and functional tissue is replaced by fibrotic scarring 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. Twenty six million patients in the U.S. alone are diagnosed with chronic kidney diseases ("CKD"). Patients with severe CKD stages (3 and 4) suffer from a gradual and accelerated loss of their renal function (end stage renal disease or ESRD) leading to the need for hemodialysis. Cardiovascular complications for ESRD patients on hemodialysis are a common cause of death.
