• Enrollment of Phase I patients to start in Q4 2014
  • Agreement for the proposed Phase II/III clinical program to follow an accelerated approval pathway
  • First PPPSTM generated plasma-derived therapeutic to enter clinical trial stages

ROCKVILLE, MD, USA: LAVAL, Canada October 28, 2014 I ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) (“ProMetic” or the “Corporation”) announced today that the US Food and Drug Administration (“FDA”) has completed its review and has cleared the Investigational New Drug (“IND”) application for ProMetic’s IV plasminogen for the treatment of hypoplasminogenemia, or type I plasminogen deficiency. When approved, this product will provide replacement therapy for patients with this condition, who suffer from a congenital lack of the normal plasminogen protein and/or its functional activity, and are subject to life-long medical problems which currently have no effective treatment.

The FDA has also accepted that ProMetic’s proposed Phase II / III clinical program for the IV Plasminogen provides an adequate surrogate endpoint for licensure using the accelerated approval pathway. To secure an accelerated pathway approval, a drug must treat a serious condition, provide a meaningful advantage over available therapies and demonstrate an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit.

“We are very pleased with the FDA’s decision and welcome their support to bring an innovative and tangible medical solution for patients affected by this severe condition that has no adequate treatment”, declared Mr. Pierre Laurin, President and Chief Executive Officer of ProMetic. “Seeing our first PPPSTM plasma-derived therapeutic enter the clinical trial stages also represents an important milestone achievement for ProMetic as we get ready to proceed with additional plasma-derived products targeting other orphan indications”, added Mr. Laurin.

The Phase I clinical trial is an open label, single ascending dose study that will investigate the safety, tolerability and pharmacokinetics of ProMetic’s plasma purified human plasminogen in 6 patients suffering from hypoplasminogenemia. The Corporation expects enrollment to commence this quarter and to progress to Phase II / III in H1 2015, and to enroll a total of 15 to 18 patients. Under the current program the Corporation expects to be in a position to be ready to file a Biological License Application (BLA) for plasminogen commercialization in Q4 2015.

Dr John Moran, Chief medical Officer of Prometic commented: “This is a significant gain for the patients and their families as it will make available for the first time an effective replacement therapy. We are committed to aggressively progressing our clinical program for the benefit of all stakeholders.”

Hypoplasminogenemia is a rare autosomal recessive disorder that leads to severe clinical manifestations, primarily associated with fibrous depositions on mucous membranes throughout the body. It is a multisystem disease that affects the eyes, ears, sinuses, tracheobronchial tree, genitourinary tract and gums. There is no effective replacement therapy currently available for this disease.

About Plasminogen:

Plasminogen is a naturally occurring protein that is synthesized by the liver and circulates in the blood. Activated plasminogen, plasmin, is an enzymatic component of the fibrinolytic system and is the main enzyme involved in the lysis of blood clots and clearance of extravasated fibrin. Plasminogen is therefore involved in wound healing, cell migration, tissue remodeling, angiogenesis and embryogenesis.

About Hypoplasminogenemia or Type 1 Plasminogen Deficiency:

The most common condition associated with plasminogen deficiency is ligneous conjunctivitis, which is characterized by thick, woody (ligneous) growths on the conjunctiva of the eye, and if left untreated, can lead to blindness. The growths tend to recur after surgical excision, thereby requiring multiple surgeries.

While ligneous conjunctivitis is the best characterized lesion of plasminogen deficiency, hypoplasminogenemia is actually a multisystem disease that can also affect the ears, sinuses, tracheobronchial tree, genitourinary tract, and gingiva. Tracheobronchial lesions including hyperviscous secretions can result in respiratory failure. Hydrocephalus has also been reported children with severe hypoplasminogenemia, apparently related to the deposition of fibrin in the cerebral ventricular system.
