  • Ryplazim™ is Prometic's Second Orphan Drug Designation (ODD) Granted for IPF by the FDA
  • Two Late Stage Clinical Assets targeting IPF: Ryplazim under BLA review and PBI-4050 entering pivotal Phase 2
    /3 clinical trials.

LAVAL, QC, Dec. 18, 2017 /CNW Telbec/ - Prometic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) (Prometic) announced today that an orphan

drug designation status has been granted to its Plasminogen (Ryplazim™) for the treatment of idiopathic pulmonary fibrosis ("IPF") by the US Food and Drug Administration (FDA).

In a gold-standard animal model proven to emulate pulmonary fibrosis in humans, Prometic's Plasminogen (Ryplazim™) performed favorably compared to recently- approved IPF drugs to treat this condition. Plasminogen (Ryplazim™) significantly reduced tissue scarring in the lungs that was observed in non-treated animals, indicating the potential for providing clinically significant improvement and stabilization in lung function.

"The fibrinolytic systems play a central role in wound healing and tissue repair, a process believed to be abnormal within the IPF affected lung," explained Dr. John Moran, Chief Medical Officer of Prometic.  "Animal models of pulmonary fibrosis have demonstrated an imbalance between thrombosis and fibrinolysis within the alveolar compartment, a finding that is also observed in IPF patients.  We plan to evaluate whether Plasminogen (Ryplazim™) can help lung function of IPF patients during acute exacerbation episodes which would be both complementary to anti-fibrotic chronic therapy and addressing and unmet medical need in the IPF patient population."

Pierre Laurin, President and Chief Executive Officer of Prometic, commented: "We are pleased to have secured a second IPF orphan drug designation from the FDA with our Plasminogen, Ryplazim™, for the treatment of this devastating disease following the initial orphan drug designation received for PBI-4050, our small molecule. This designation supports our decision to aggressively pursue the development of Plasminogen in additional acute care medical conditions where the healing and fibrinolysis process is impaired."

Orphan Drug Designation is granted to drugs or biologics that treat a rare disease or condition affecting fewer than 200,000 patients in the U.S. The designation provides the drug developer with a seven-year period of U.S. marketing exclusivity upon marketing approval for the designated indication, as well as with tax credits for clinical research costs, the ability to apply for annual grant funding, clinical research trial design assistance and the waiver of prescription drug user fees.

More about Idiopathic Pulmonary Fibrosis (IPF) and Acute Exacerbation

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. IPF affects about 130,000 people in the United States, with about 48,000 new cases diagnosed annually. Approximately 40,000 people with IPF die each year, a similar number of deaths to those due to breast cancer. The 5-year mortality rate for patients with IPF is estimated to range from 50% to 70%. Acute exacerbation of IPF (AE-IPF) is defined as a sudden acceleration of the disease or an idiopathic acute injury superimposed on diseased lung that leads to a significant decline in lung function. An AE-IPF is associated with a mortality rate as high as 85% with mean survival periods of a few months.

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.
