Gelatinase B Involved Early in Septic Shock, May Be Therapeutic Target

NEW YORK (Reuters Health) Sept 13 - The pathophysiology of endotoxin shock is mediated early in the disease process by gelatinase B, results of a new study indicate. This finding suggests that early blockade of this enzyme, also known as matrix metalloproteinase (MMP)-9, may ameliorate the course of septic shock syndromes.
According to their report in the European Journal of Immunology for August, Dr. Ghislain Opdenakker of the University of Leuven in Belgium and associates generated gelatinase B-knockout mice and compared their response to Escherichia coli lipopolysaccharide (LPS) with that of wild-type mice.
Before and after they treated the animals with LPS, MMP-mRNA expression (except for MMP-9) was similar in the knockout mice and their wild-type counterparts. Levels of tissue inhibitor of MMP (TIMP) and varius cytokines were also similar.
Leukocytes collected from control mice 1 hour after LPS bolus were found to be maximally degranulated, and serum levels of gelatinase B increased. This activity was ablated in the mutant mice, the researchers report.
Survival after injection of 300 g LPS was significantly longer in MMP-9-negative mice than wild-type animals older than 8 weeks (p = 0.025). The difference was even more pronounced in mice younger than 4 weeks (p = 0.01). "Gelatinase B inactivation was thus found to protect against morbidity and mortality in endotoxin shock, and our data illustrate that this enzyme is a key pathogenic factor," Dr. Opdenakker's group writes.
The authors note that, at a later stage in endotoxemia, gelatinase B is also induced by tumor necrosis factor-alpha. However, by the time this pathway might be interrupted by TNF-alpha blockade, MMP-9 would already have induced significant pathology.

ProMetic Life Sciences and AM-Pharma Announce Achievement of First Milestone in Sepsis Venture

MONTREAL, Canada, Sept. 27 /CNW/ - ProMetic Life Sciences (TSX: PLI) and
AM-Pharma Holding BV, announced today the achievement of their first milestone
in the development of new therapeutic approaches for the treatment and
diagnosis of sepsis and septic shock.
The first milestone of this program - the identification of affinity
ligands based on Prometic's proprietary Mimetic Ligand(TM) technology which
display the required affinity and selectivity for use in the isolation of
alkaline phosphatase from different sources, has been successfully achieved.
This work was conducted at Prometic's research & development facility based in
Cambridge, U.K.
According to Dr. Steve Burton, Vice President R&D, Prometic BioSciences
Ltd, a wholly-owned subsidiary of Prometic, "The completion of this first
milestone is very significant since it opens the way to a commercial process
for the manufacture of highly purified alkaline phosphatase suitable for use
in the treatment of sepsis". Dr. Burton added, "once again, Prometic's ability
to develop specific binding ligands according to agreed specifications and
timelines has been demonstrated. In common with most Mimetic Ligands(TM)
compounds, the molecules Prometic has identified are very robust synthetic
compounds which are ideally suited to use in downstream process applications
and for the development of stable diagnostic products."
PharmAAware Sepsis BV, a subsidiary of AM-Pharma Holding BV was first to
identify alkaline phosphatase as a promising therapeutic agent for the
treatment of sepsis. In the initial stages of sepsis, the immune system
recognizes foreign endotoxin molecules (lipopolysaccharide (LPS)) on the
surface of infecting bacteria and mounts an exaggerated inflammatory response,
which leads to septic shock and possibly, death. The body normally produces
low levels of alkaline phosphatase, which inactivates LPS present in the
blood. However, normal physiological concentrations of alkaline phosphatase
are not sufficient to prevent septic shock, making a purified, therapeutic-
grade alkaline phosphatase a very attractive therapeutic approach.
Under the terms of a previously released licensing agreement, both
parties committed to a two-year program to develop highly purified,
therapeutic-grade alkaline phosphatase for use in the treatment and diagnosis
of sepsis. The Company expects these therapeutics to enter the clinics
shortly.

ABOUT SEPSIS
Sepsis is a major challenge in medicine. Particularly in elderly, immuno-
compromised and critically ill patients, sepsis is a major cause of morbidity
and mortality in intensive care units worldwide (Friedman, 1998, Balk, 2000).
In the US, it is estimated that more than 700,000 cases of severe sepsis,
hypoperfusion or shock occur per year (Linde-Zwirble, 1999), which when
extrapolated to a global population represents several million cases of severe
sepsis annually worldwide. Data also shows that sepsis is the leading cause of
death in non-coronary ICU patients (Sands 1997), and data collected by the
Centers for Disease Control in 1998 shows that it was the 11th leading cause
of death overall. The CDC warned that the incidence was increasing, citing the
aging of the US population and the increased prevalence of human
immunodeficiency virus (HIV) infection as contributing factors. Also, the
widespread use of broad-spectrum antibiotics has increased the rates of both
antibiotic resistance and nosocomial infections of sepsis. A recent study
published in Crit. Care. Med. (2001) Vol. 29, No.7, clearly demonstrates the
ongoing increase of these conditions that are frequently fatal and expensive
for the healthcare system.

This press release contains forward-looking statements that involve risks
and uncertainties, including, but not limited to the Company's ability to
develop, manufacture, and successfully commercialize value-added
pharmaceutical products and to obtain contracts for its products and services
and commercial acceptance of advanced affinity separation technology.
Shareholders are cautioned that these statements are predictions and these
actual events or results may differ materially from those anticipated in these
forward-looking statements.
