Juvaris BioTherapeutics Announces Evaluation
of Products for Biodefense Applications
Juvaris Immunostimulation and Vaccine Technologies
to be Tested in Anthrax and Small Pox Models in Conjunction with
DARPA
Pleasanton, CA - October 5, 2004
Juvaris BioTherapeutics, Inc. announced today that researchers
at the University of New Mexico have begun evaluation of the efficacy
of the JuvImmuneTM immunostimulant platform against Anthrax and
Small Pox infection models. This novel technology is capable of
rapidly activating the innate immune response for the production
of different cytokines including interferons (alpha, beta & gamma)
as well as IL-12 and TNF-alpha. These cytokines are the first-line
of defense against infectious agents and are critical for induction
of subsequent immune responses. Preclinical results from rodent,
canine and non-human primate studies have demonstrated substantial
amplification of immune responses by the JuvImmuneTM immunostimulant.
In addition, the testing will determine the efficacy of the JuvaVaxTM
vaccine platform containing disease-specific antigens as a potential
oral vaccine against Anthrax. JuvaVaxTM vaccines have demonstrated
significant induction of both humoral (antibody) and cellular (cytotoxic
T lymphocytes) antigen-specific immune responses. These balanced
immune responses are essential for preventing and/or reducing the
severity of bacterial and viral infections. This testing is sponsored
by the Defense Advanced Research Projects Agency (DARPA).
"We are pleased that DARPA is interested in evaluating the Juvaris
immunostimulant and vaccine technologies. We believe that these
products have significant military and civilian applications," said
Martin D. Cleary, Co-founder, Chairman and CEO of Juvaris. "In the
case of bioterrorism or bioweapons defense, traditional approaches
such as avoidance, disinfection, and antimicrobial drug prophylaxis
may not be sufficient to prevent widespread physical and economic
injury. Juvaris' therapeutic vaccine platform and products, which
will emerge from this technology, will augment more traditional
approaches to defend against infectious diseases."
About Juvaris
Juvaris BioTherapeutics was created in 2002 to develop an immunotherapeutic
product platform for the treatment of infectious diseases and cancer
using lipid-DNA complexes. Cationic lipids are formulated with non-coding
DNA (plasmid) to create JuvImmuneTM, a single lipid-DNA complex,
which as an immunostimulation product will have utility in a number
of non-antigen immunotherapeutic applications. The DNA in these
complexes does not code for protein, but rather, through a combined
synergistic effect with lipids, strongly stimulates immune responses.
The JuvImmuneTM product has been shown to be at least 50-times
more potent at triggering innate immune activation and interferon
release than current immune stimulants. Juvaris was recently issued
Patent No. 6,693,086 titled "Systemic Immune Activation Method Using
Nucleic Acid-Lipid Complexes" providing broad intellectual property
coverage for the JuvImmuneTM technology.
When combined with disease-specific antigens, the technology creates
JuvaVaxTM vaccines capable of activating substantial antibody- and
cell-mediated immune responses, particularly induction of cytotoxic
T lymphocytes. Immunological responses elicited by the lipid-DNA
complexes have been successfully demonstrated in both prophylactic
and therapeutic settings in a variety of mammals including rodents,
rabbits, cats, dogs and non-human primates. This technology provides
the opportunity to develop many disease-specific vaccine products,
for which there are significant unmet medical needs.
Over the past six months, the Company has announced collaborations
or investigational studies with Cell Genesys, SomaGenics, the University
of California-San Francisco, Penn State University, and now the
Defense Advanced Research Projects Agency (DARPA).
