Prometic announces the addition of Scleroderma to PBI-4050’s targeted indications

  • Significant reduction of overproduction of collagen and fibrosis in a scleroderma preclinical model confirmed at Vanderbilt University
  • Upcoming double-blind, placebo controlled phase 2 clinical trial to focus on fibrosis reduction in skin and affected organs

LAVAL, QUEBEC, CANADA – March 15, 2016 – ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) (“ProMetic” or the “Corporation”) today announced that it will be initiating a double-blind, placebo-controlled phase 2 clinical trial in patients suffering from scleroderma.

There is no cure for scleroderma, a chronic disorder characterized by an overproduction of collagen and abnormal growth of connective tissue. This collagen accumulation causes scarring (fibrosis) of the skin, and in the case of systemic scleroderma, also affects internal organs such as the lungs, the kidneys and gastrointestinal system. Scleroderma affects approximately 300,000 individuals in North America alone and varies in severity.

“PBI-4050 has been shown to significantly reduce fibrosis in several of the key organs in various preclinical models, irrespective of the cause of the injuries or whether acute or chronic in nature”, stated Dr. Lyne Gagnon, VP of R&D preclinical at ProMetic. “The most recent results have shown that even in mice genetically programmed to develop scleroderma, PBI-4050 prevented the over production of collagen and the formation of fibrotic scarring”, added Dr. Gagnon.

Dr. John Moran, Chief Medical Officer of ProMetic commented: “This accumulated data is very promising for patients affected by scleroderma in that, even though we do not understand the cause or causes of their condition, PBI-4050 addresses the underlying pathological process leading to the scarring of tissues and organs. This double-blind, placebo-controlled phase 2 clinical trial will investigate whether PBI-4050 can prevent or even reverse fibrosis in the skin and key target organs such as the lungs”.

“ProMetic is focused on and committed to targeting unmet medical needs where fibrosis is the underlying process leading to the medical complications”, stated Pierre Laurin, President and Chief Executive Officer of ProMetic who added, “We are merely leveraging PBI-4050’s proven ability to downregulate the excessive production of scarring tissue, which in the case of systemic scleroderma, is often life threatening”.

More about scleroderma (1):

Derived from the Greek words “sclerosis” meaning hardness and “derma” meaning skin, scleroderma literally means hard skin. Scleroderma, also known as systemic sclerosis, is a progressive and chronic connective tissue disorder. Some unknown factor triggers the over-production of collagen (body protein) causing thickening, hardening and scarring of the skin and internal organs. Normally collagen keeps the skin soft, but the overproduction makes the affected tissue thick and hard. This, in turn, affects the amount of blood the small vessels carry to many parts of the body.

The most characteristic feature of scleroderma is the presentation of hard, hide-bound thickening of the skin. Less visible but of major importance are the lesions that occur in small blood vessels (vascular lesions), which may involve major organs.

The natural history, or course of scleroderma, varies widely from that of a mild nuisance to a severe multi-system disease. Forms of the disease that primarily affect the skin without major organ involvement, have better long-term outlook. Those forms of scleroderma that involve major organs, such as the heart and kidney, are potentially more severe with possibly less desirable long-term outcomes.

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.
