LAVAL, QC, June 13, 2016 /CNW Telbec/ - ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) ("ProMetic" or the "Corporation") reported today that the U.S. Food and Drug Administration (FDA) has granted a Fast Track designation to ProMetic for its plasminogen drug candidate, currently in a phase 2/3 clinical trial in patients suffering from congenital Plasminogen deficiency.
Fast Track designation is a process designed to facilitate the development and expedite the review of drugs to treat serious conditions that fill an unmet medical need, with the main objective of getting important new drugs to the patient earlier. To gain Fast Track designation, Plasminogen therapy demonstrated a strong rationale for its use as a treatment for a serious, often morbid and potentially fatal, condition as well as for treating an unmet medical need which previously largely relied on repeated surgeries to remove recurring obstructive and debilitating lesions.
"To date, our plasminogen therapy has been well tolerated and initial compassionate use treatments have shown a rapid response in lesion resolution and have helped avoid the need for surgery", said Mr. Pierre Laurin, ProMetic's CEO. "This was recently evidenced with a patient who, under an expanded access protocol, avoided an 8th surgery to his kidney by opting for ProMetic's plasminogen infusion therapy instead. Fast Track designation is an important milestone and we continue to work closely with the FDA to expeditiously bring our Plasminogen to patients with congenital Plasminogen deficiency", added Mr. Laurin.
In addition to allowing for more frequent meetings with the FDA to discuss the drug's development plan and ensure collection of appropriate data needed to support drug approval, a drug that receives a Fast Track designation is also eligible for a Rolling Review of the Biologic License Application (BLA) by the FDA, allowing the review to proceed more efficiently and facilitating earlier drug approval and access by patients.
ProMetic's Plasminogen was also granted Orphan Drug Designation by the FDA and the European Commission for the US and the European markets respectively. As an orphan drug designated product, ProMetic's Plasminogen is also eligible for priority review of the BLA, which reduces the standard review period by 6 months and so also speeds the time to availability of this important medicine on the market.
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 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.
More about Fast Track Designation
The Food and Drug Administration Modernization Act of 1997 (FDAMA) includes Section 112, "Expediting study and approval of fast track drugs." This section mandates the Agency 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. Fast track adds to existing programs, such as accelerated approval, the possibility of a "rolling review" for an application. An important feature of fast track is that it emphasizes the critical nature of close early communication between the FDA and sponsor to improve the efficiency of product development.
Rolling Review means that a drug company can submit completed sections of its Biologic License Application (BLA) for review by FDA, rather than waiting until every section of the BLA is completed before the entire application can be reviewed. BLA review usually does not begin until the drug company has submitted the entire application to the FDA.
