ProMetic Reports Successful PBI-4050 Pre-IND Meeting with the FDA

LAVAL, QUEBEC-- (Sep 3, 2014) - ProMetic Life Sciences Inc. (PLI.TO)(PFSCF), ("ProMetic" or the "Corporation") announced today it had a successful Pre-Investigational New Drug ("Pre-IND) meeting with the US Food and Drug Administration ("FDA") for its anti-fibrotic, lead drug candidate, PBI-4050.

This Pre-IND meeting with the FDA focused on ProMetic's proposed phase II clinical program, for PBI-4050, in patients with diabetic kidney disease ("DKD"), other rare diseases as well as the manufacturing and pre-clinical package that ProMetic intends to include in the IND submission.

ProMetic has already completed a Phase I clinical trial in forty (40) healthy volunteers under a Canadian Clinical Trial Application ("CTA") where PBI-4050 was found to be safe and very well tolerated without any serious adverse events reported.

Dr. John Moran, ProMetic's Chief Medical Officer, commented: "Based on this FDA meeting ProMetic now has a clear path forward regarding the design of the clinical trial to be performed in DKD patients. This is an important milestone as we move forward with this multi-center study in Canada and the USA, as we have now received valuable input and favorable comments as to how to proceed from both the FDA and Health Canada".

"As a result of these successful Pre-IND meetings with both the FDA and Health Canada, we now plan to file a series of CTAs and INDs. These will target two orphan indications in addition to DKD. We aim to initiate these trials in the fall", stated Pierre Laurin, President and Chief Executive Officer of ProMetic.

The multi-center study for DKD will be 3-arm, double-blind, placebo-controlled involving 2 different doses of PBI-4050. The trial will be performed at sites already identified across Canada and in the USA. The clinical trials targeting the orphan indications will be open label in order to monitor progress against well-established disease state baselines. The trials will monitor safety and tolerability in patients as well as the effect of PBI-4050 on recognized biomarkers for fibrosis and diabetes in blood and urine.

More on DKD

Diabetic nephropathy is a complication of long-standing diabetes mellitus, of both Type 1 and Type 2. It is increasing in incidence throughout the world, and in many countries, including the United States and Canada, is the leading cause of end-stage renal disease requiring maintenance dialysis and/or kidney transplantation.

More on PBI-4050

PBI-4050 is an orally active lead drug candidate with efficacy and excellent safety 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 gradually 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. 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.
