ProMetic Reports Successful PBI-4050 Pre-IND Meeting with the US FDA for Idiopathic Pulmonary Fibrosis ("IPF")

- ProMetic allowed to proceed with filing of IND for pivotal study ahead of anticipated timelines

- PBI-4050 to be added in combination to commercially available drugs in pivotal study

LAVAL, QUEBEC--(Marketwired - Oct. 1, 2015) - ProMetic Life Sciences Inc. (TSX:PLI)(OTCQX: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 orally active anti-fibrotic lead drug candidate, PBI-4050.

The meeting with the FDA focused on ProMetic's proposed clinical development program for PBI-4050 in patients with IPF, and particularly on an optimal design for the first pivotal clinical trial that will incorporate the current standards of care for IPF in the US. The two drugs commercially available to treat IPF have been shown in clinical trials to slow the progression of the disease, but not to reverse it. Treatment of this devastating condition therefore remains an urgent medical need, and IPF patients could potentially benefit from PBI-4050, either alone or in combination with current therapies. It is notable that in the gold standard preclinical model used to emulate pulmonary fibrosis in humans, PBI-4050 performed favorably compared to these recently approved drugs, and demonstrated synergistic effects when combined with pirfenidone (Esbriet®).

"The outcome of this meeting is that ProMetic will proceed with a placebo-controlled pivotal study in the USA in order to evaluate the combination of PBI-4050 with nintedanib or pirfenidone", commented Dr. John Moran, ProMetic's Chief Medical Officer. "This is an important milestone as it allows us to move forward with this multi-center study sooner than anticipated, and with a clear regulatory path".

The multi-center pivotal study will be a double-blind, placebo-controlled design with IPF patients on pirfenidone or nintedanib randomized to receive either PBI-4050 or a placebo. The study will be powered to demonstrate a statistically significant difference in forced vital capacity ("FVC") changes between the PBI-4050 combination therapies and the current standards of care. The design of the definitive protocol is currently being completed by consultants expert in this field, and ProMetic expects to file its IND with the FDA during the first quarter of 2016.

"To date, PBI-4050 has presented a remarkable safety and tolerability profile throughout our phase I trials and ongoing phase II clinical trial", said Mr. Pierre Laurin, CEO of ProMetic. "The objective of this pivotal trial is to demonstrate that PBI-4050 can safely provide significant additional clinical benefits to IPF patients and we appreciate the input of the FDA regarding the design of the trial".

About Idiopathic Pulmonary Fibrosis ("IPF")

Idiopathic pulmonary fibrosis (IPF) is a chronic, devastating, and ultimately fatal disease characterized by a progressive decline in lung function. It is a specific type of interstitial lung disease in which the small air sacs of the lung, the "alveoli," gradually become replaced by fibrotic (scar) tissue and is the cause of worsening dyspnea (shortness of breath). IPF is usually associated with a poor prognosis. The term 'idiopathic' is used because the cause of pulmonary fibrosis is still unknown. IPF usually occurs in adult individuals of between 50 and 70 years of age, particularly those with a history of cigarette smoking, and affects men more often than women.

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. 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.
