VACCINE USING L.E.A.P.S.(TM) TECHNOLOGY PLATFORM IS DESIGNED TO
ADDRESS MUTATED FORMS OF SWINE INFLUENZA AND CAN ACT AS BOTH
PREVENTATIVE AND THERAPEUTIC VACCINE VIENNA, Va., June 9
/PRNewswire-FirstCall/ -- CEL-SCI Corporation (NYSE Amex: CVM)
announced today that it is expanding the pre-clinical testing of
its flu vaccine, utilizing its proprietary L.E.A.P.S. technology
(Ligand Epitope Antigen Presentation System) to determine its
efficacy against the more dangerous and virulent virus strains that
may arise during the up coming winter flu season. The Company has
begun pre-clinical formulation, evaluation and testing of a new
application of its L.E.A.P.S vaccine, which will allow the
targeting of "mutated" versions of H1N1 swine and other influenza
viruses. It is believed that the influenza virus may mutate and
evolve between now and the winter flu season. In conjunction with
the testing, CEL-SCI has produced several L.E.A.P.S. flu vaccines
that focus on the conserved, non changing epitopes of the different
strains of Type A Influenza viruses (H1N1, H5N1, H3N1, etc.),
including "swine", "avian or bird", and "Spanish Influenza", in
order to minimize the chance of viral "escape by mutations" from
immune recognition. CEL-SCI's L.E.A.P.S. flu vaccine contains
epitopes known to be associated with immune protection against
influenza in animal models. The Company had previously announced
that it had begun pre-clinical testing of swine and H1N1 flu
viruses, which were non-mutated versions of the virus. The use of
L.E.A.P.S. vaccine technology for immunization in animal models has
already been shown to provide protection from viral diseases
without causing an immune response associated with the deadly
"cytokine-storm" seen in many of the victims of influenza. Dr.
Daniel Zimmerman, inventor of the L.E.A.P.S. technology, and
currently a consultant to CEL-SCI, said, "Various L.E.A.P.S.
technology constructs have already been shown to induce protection
in animal challenge models against a variety of diseases such as
malaria and herpes simplex virus and as therapeutic vaccines in two
different autoimmune conditions. Data showed that L.E.A.P.S.
vaccines were able to induce these protective immune responses
without the excessive induction of pro-inflammatory cytokines. This
is thought to be very important in the swine flu, or the avian flu,
since it appears that the excessive production of pro-inflammatory
cytokines during the course of the disease is responsible for and
may lead to the increased number of deaths from these illnesses."
Recently, collaborators at the University of Hawaii reported on
data at the annual American Society for Microbiology in
Philadelphia, PA. This data demonstrates that vaccines utilizing
its L.E.A.P.S. vaccine technology with specificity for particular
Mycobacterium tuberculosis (TB) antigens can elicit immune
responses that would be protective against tuberculosis and have
the potential to treat swine and other H1N1 influenzas. The
investigators presented data that showed that blood and spleen
cells from immunized mice produced gamma interferon in response to
the vaccine, while the cells from mice in the various control
groups did not. 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(R) which is
currently being readied for a global Phase III trial. The Company
has operations in Vienna, Virginia, and Baltimore, Maryland. When
