ProMetic Life Sciences Inc. (TSX:PLI) (OTCQX:PFSCF), ("ProMetic" or the
"Corporation") presented new preclinical data at the 2013 American Society of
Nephrology ("ASN") annual meeting held in Atlanta on November 7-10, 2013. 


Cardiovascular diseases, in their broad spectrum, are collectively the major
cause of death in patients on dialysis. One of the studies performed was to
determine the effect of a permanent vascular catheter on heart fibrosis and to
investigate the potential protective effect of PBI-4050 on the kidneys and the
heart of 5/6 nephrectomised rats. In this study, the nephrectomised rats with a
catheter had 4 times more heart lesions (fibrosis, necrosis and inflammation)
compared to those who did not have a catheter. The rats with catheter and
treated with PBI-4050 had a significant reduction of heart lesions, fibrosis and
collagen compared to the non-treated animals. The nephrectomised rats treated
with PBI-4050 also displayed a significant improvement of their renal function
and a significant reduction of inflammation and fibrosis in their kidneys
compared to the non-treated rats.


"this study is particularly important because it provides a potential mechanism
for reducing the cardiac injury that many patients who use catheters as a
vascular access while on dialysis may experience", stated Dr Raymond Hakim.


Dr. Lyne Gagnon presented an overview of all the pre-clinical data that
demonstrates the ability of PBI-4050 to reduce fibrosis in the kidney and
overall improve the renal function in various animal models; said models ranging
from the uni-nephrectomised diabetic (db/db) mouse model simulating diabetic
nephropathies (DKD) to the 5/6 nephrectomised rat model emulating chronic kidney
disease (CKD) in humans.


"Patients with advanced CKD conditions, whether or not on dialysis, present a
very complex medical profile often involving hypertension, diabetic and
cardiovascular complications. The pre-clinical data strongly suggests that
PBI-4050 could provide a novel approach to modulate the process that leads to a
gradual loss of the renal function in these patients", commented Dr. Raymond
Hakim. 


"These new findings add significant weight to our ultimate strategic positioning
of PBI-4050 going forward", stated Dr John Moran, who added "any beneficial
clinical effect in diabetic patients with chronic kidney diseases ought to be
part of a new clinical mindset when evaluating the performance of a drug".


The Corporation expects to start enrolling patients in early 2014 to demonstrate
efficacy.
