ProMetic confirms PBI-4050's Anti-Fibrotic Effect in Nash Model and on Human Hepatic Stellate Cells

  • Down regulation of fibrotic biomarkers in human hepatic stellate cells (HHSC); key cells involved in liver fibrosis.
  • PBI-4050 significantly reduces liver fibrosis in NASH model.

LAVAL, QC, April 14, 2016 /CNW Telbec/ - ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) ("ProMetic" or the "Corporation") presented today new data at the 2016 European Association for the Study of the Liver (EASL)'s 51st Annual Meeting – The International Liver Congress (ILC) in Spain.

The new data confirms that PBI-4050's anti-fibrotic effect demonstrated in the livers of different animal models has been successfully reproduced in human hepatic stellate cells ("HHSC") during in vitro preclinical experiments designed to simulate fibrogenesis in the liver. PBI-4050 was found to down-regulate key pro-fibrotic biomarkers considered to be driving the fibrotic process in NASH.

Dr. Lyne Gagnon, Vice-President, R&D, Preclinical of ProMetic commented: "It is exciting to see that the anti-fibrotic activity of PBI-4050 observed in a NASH animal model correlates with the down-regulation of fibrotic markers in human HHSC activation, where HHSC is considered as a key player in the fibrogenic process of the liver. It is also very important to note that all key fibrosis biomarkers such as CTFG and αSMA were also down-regulated to their normal respective levels", added Dr. Gagnon.    

 "We continue to build evidence that PBI-4050 works on human cells in a predictable way, entirely in agreement with what we see in standard animal models of fibrosis," stated Dr John Moran, Chief Medical Officer of ProMetic. "This new data follows evidence of efficacy in human kidney and skin cells, and of course our recent statistically significant clinical results in patients with metabolic syndrome and type 2 diabetes. Going forward we will be monitoring very closely the effect of PBI-4050 on the liver, which is an organ particularly affected in patients suffering from Alström syndrome or cystic fibrosis, as well as many more common disease entities."

ProMetic will present two posters at the International Liver Congress; one on its lead clinical drug candidate, PBI-4050, and the other on a follow on compound, PBI-4425, entitled:

MORE ABOUT PBI-4050

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 believed to suffer from chronic kidney diseases ("CKD"). Patients with severe CKD stages (3 and 4) suffer from a progressive loss of their renal function leading to end-stage renal disease and the need for dialysis or kidney transplant. Cardiovascular complications are the most common cause of death in dialysis patients.
