CEL-SCI Developing Immune-Based Treatment Against Swine and Other H1N1 Flu Viruses Using Proprietary L.E.A.P.S. Technology

VIENNA, Va. May 26 /PRNewswire-FirstCall/ -- CEL-SCI Corporation
(NYSE AMEX: CVM) announced today that it is developing an
immune-based treatment for the "swine flu and related H1N1" flu
viruses, utilizing its proprietary L.E.A.P.S.(TM) (Ligand Epitope
Antigen Presentation System) vaccine technology. The Company plans
to utilize the expertise and knowledge it has gained from
developing protective and therapeutic vaccines utilizing L.E.A.P.S.
to develop a therapeutic treatment based upon the technology for
people infected with the swine and H1N1 flu viruses. CEL-SCI has
already commenced pre-clinical testing. Previously, CEL-SCI
announced that its CEL-1000 peptide, which is derived from the
L.E.A.P.S. technology, showed adjuvant activity when used with a
peptide based malaria vaccine and a DNA based malaria vaccine in
animal challenge studies as part of a Cooperative Research
arrangement with the Naval Medical Research Center, Silver Spring,
MD. In both cases, the addition of CEL-1000 to the vaccines
resulted in significant increases in the protection of the animals.
In addition, several different L.E.A.P.S. conjugates induced
protection and/or improvement in diseases as diverse as rheumatoid
arthritis, malaria, TB and herpes simplex viruses. This shows that
the L.E.A.P.S. technology can be successfully applied to many
different diseases and these results further suggest that
L.E.A.P.S. has the potential to be used either alone as a therapy
or as an adjuvant to vaccines under development for the treatment
of H1N1 related flu viruses. Adjuvants are designed to improve the
effectiveness of vaccines. "We believe that our L.E.A.P.S.
technology platform offers strong potential to address the current
swine and H1N1 flu viruses," said Dr. Daniel Zimmerman of CEL-SCI,
the inventor of the technology. "With the swine flu currently
creating major global health problems despite it occurring outside
of the traditional windows for the flu, we are working diligently
to provide a solution as it is expected that the disease may become
even more virulent later this year during the traditional flu
season." The reason why the L.E.A.P.S. technology lends itself to
creating a much more effective immune therapy against the H1N1 flu
virus is because the L.E.A.P.S. conjugates induce an effective and
powerful immune response without causing excessive amounts of
pro-inflammatory cytokines. In the case of prior pandemic
influenza, such as the "Spanish Influenza" and more recently the
"Avian Flu", patients with stronger immune systems had a greater
chance of dying because their immune response was too strong (too
many pro-inflammatory cytokines). This is called a cytokine storm.
While normally many cytokines play a key role in preventing and
treating swine flu, in some cases excessive cytokine amounts may
exacerbate the disease as it appears that, unlike the normal flu
which affects the very young and very old most severely, swine flu
may be more like the avian flu which hits people in their prime
more severely. In addition, LEAPS conjugates may be used to
potentially overcome the virus' mutations by focusing on more
conserved and common epitopes critical for critical viral function.
The L.E.A.P.S. technology is a novel T-cell modulation platform
technology that enables CEL-SCI to design and synthesize
proprietary immunogens. Any disease for which an antigenic sequence
has been identified, such as infectious, parasitic, malignant or
autoimmune diseases and allergies, are potential therapeutic or
preventive sites for the application of L.E.A.P.S. technology. Each
L.E.A.P.S. construct is composed of a T cell binding ligand (TCBL)
which has previously demonstrated the ability to induce and elicit
protective immunity and antigen specific antibody production in
animal models. The concept behind the L.E.A.P.S. technology is to
directly mimic cell/cell interactions on the dendritic and T-cell
surface with synthetic peptides. The L.E.A.P.S. constructs
containing the antigenic disease epitope linked to an Immune/T-cell
binding ligand (I/TCBL) can be manufactured by peptide synthesis or
by covalently linking the two peptides. Depending upon the type of
L.E.A.P.S. construct and I/TCBL used, CEL-SCI is able to direct the
outcome of the immune response towards the development of T-cell
function with primarily effector T-cell functions (T Lymphocyte;
helper/effector T lymphocyte, type 1 or 2 [Th1 or Th2], cytotoxic
[Tc] or suppressor [Ts]). The L.E.A.P.S. vaccine constructs are
chimeric peptides which combine antigen specificity with immune
response modulation. CEL-SCI Corporation is developing products
that empower immune defenses. Its lead product is Multikine which
is being readied for a global Phase III trial. The Company has
operations in Vienna, Virginia, and Baltimore, Maryland. When used
