Prometic completes patients' enrolment in pivotal plasminogen phase 2/3 clinical trial

  • Patients enrolment for the accelerated regulatory approval pathway completed
  • Filing of Biologics License Application ("BLA") to start in Q4 2016

LAVAL, QC, Aug. 11, 2016 /CNW Telbec/ - ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) ("ProMetic" or the "Corporation") announced today that it has completed enrolment of the congenital plasminogen deficient patients in its pivotal phase 2/3 clinical trial required for the accelerated regulatory approval pathway with the Food and Drug Administration ("FDA").

The FDA has agreed to an accelerated regulatory approval pathway, given the rarity of the condition and the related unmet medical need. 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 timely completion of patients' enrolment in our pivotal plasminogen phase 2/3 trial", said Mr. Pierre Laurin, President and Chief Executive Officer of ProMetic. "The achievement of this important milestone allows us to confidently proceed with the last phase of the plasminogen congenital deficiency clinical program as we get ready to start filing the required BLA modules necessary to secure licensure from the FDA".  

Dr John Moran, Chief Medical Officer of ProMetic commented: "The ongoing clinical trial has enabled us to meet the primary end-point of achieving the targeted increase in plasma concentration of plasminogen and to define the optimal treatment regimen. We have also observed major clinical benefit in patients with long-standing lesions related to their plasminogen deficiency. As in the patients who have been treated outside the trial on an emergency basis, both the rapidity and the magnitude of the improvement has been remarkable, knowing that in many cases the lesions have been present for years".

ProMetic's Plasminogen has received an Orphan Drug Designation by the FDA and the European Commission for the US and the European markets respectively. ProMetic also received a Fast Track Designation by the FDA, a process designed to facilitate the development and expedite review of drugs and biologics intended to treat serious or life-threatening conditions and that demonstrate the potential to address unmet medical needs.

About Plasminogen

Plasminogen is a naturally occurring protein that is synthesized by the liver and circulates in the blood. Activated plasminogen, plasmin, is a fundamental 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 vital in wound healing, cell migration, tissue remodeling, angiogenesis and embryogenesis.

About 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 a multiorgan 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 in children with severe hypoplasminogenemia, apparently related to the deposition of fibrin in the cerebral ventricular system.
