Prometic’s PBI-4050: Efficacy further evidenced in type 2 diabetic and metabolic syndrome clinical trial

April 26, 2016 Fred Dumais
  • New results from additional patients increase statistical and clinical evidence of efficacy.
  • Reduction of glycated hemoglobin (HbA1c) reaches -0.9% (p=0.0004) in patients with HbA1c ≥ 8% at baseline
  • PBI-4050 continues to improve other physical parameters related to metabolic syndrome (waist circumference, body weight and body mass index)
LAVAL, QUEBEC, CANADA, – April 26, 2016 – ProMetic Life Sciences Inc. (TSX: PLI) (OTCQX: PFSCF) (“ProMetic” or the “Corporation”) announced today that new data including an additional nine patients enrolled in its PBI-4050 phase 2 open label study in patients suffering from type 2 diabetes and metabolic syndrome confirms the efficacy initially reported in the first 11 patients that had completed the treatment period in December, 2015. In these additional nine patients, administration of PBI-4050 resulted in similar pharmacological activity on the diabetic and metabolic parameters, including the decrease in HbA1c as was shown in the original 11 patients.
Dr. Moran, ProMetic’s Chief Medical Officer explained: “This ongoing clinical study enabled us to confirm that PBI-4050 can be safely added to a cocktail of antihyperglycemic drugs in diabetic patients with elevated HbA1c. With results now available from twenty patients, we are also able to see the effect in a larger number of patients with elevated HbA1c levels of > 7.5% or even ≥ 8%, which is the typical inclusion criterion of other diabetic drug clinical trials. In the thirteen patients enrolled with an HbA1c > 7.5%, we observed an average decrease of -0.75% (p=0.0004). This average decrease was -0.9% in seven patients with HbA1c levels of ≥ 8% (p=0.0004). These results compare very favorably with commercially available antidiabetic drugs. We have clear evidence that PBI-4050 provides significant benefit when added to routine therapy with oral antidiabetic agents”, concluded Dr. Moran.
A recent and comprehensive review of randomized controlled clinical trials involving 24,163 patients that studied the effect of commercially approved antihyperglycemic drugs, DPP-4 inhibitors, on HbA1c reported an average reduction of -0.77%, with a mean baseline HbA1c value of 8%.
Dr. Peter Senior, Professor of Medicine and Director of the Department of Endocrinology at the University of Alberta, the principal investigator for the clinical trial, commented: “This drug continues to demonstrate a consistent efficacy and safety profile in patients with Type 2 diabetes. We also noticed that the level of HbA1c rose in most patients within one month after completing the study’s course and ceasing to receive PBI-4050. This rise of HbA1c after “washout” is strong evidence of a true benefit of PBI-4050”.
“PBI-4050’s reduction of HbA1c in our open label trial is a very strong efficacy signal that provides us with very valuable insight for the placebo controlled clinical trial design in patients with Chronic Kidney Disease with diabetes and in patients with metabolic syndrome and diabetes”, commented Pierre Laurin, CEO of ProMetic. “We are very confident about the prospect of PBI-4050’s clinical performance in the other on-going clinical trials and the placebo controlled studies we are initiating”, added Mr. Laurin.
The Corporation previously disclosed the clinical programs of PBI-4050 to include placebo controlled studies in patients with cystic fibrosis and related diabetes, patients with chronic kidney disease and diabetes, patients with scleroderma and patients with idiopathic pulmonary fibrosis. Further updates on the various PBI-4050 clinical programs will be provided during the forthcoming Annual Meeting of Shareholders to be held on May 11, 2016.
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.
