Juvaris and SomaGenics Announce Collaboration
on Combination Products
Group will focus on the synergy of inhibitory
RNA with a directed immune response
Pleasanton, CA - May12, 2004
Juvaris BioTherapeutics Inc., and SomaGenics, Inc., private biotechnology
companies, today announced they have entered into a collaboration
to develop products combining their technologies. This approach
combines the RNA-based gene inhibition technology of SomaGenics
with the immunomodulatory and vaccine technology under development
by Juvaris BioTherapeutics. The effort is directed towards the development
of novel methods for immediate inhibition of pathogenesis, stimulation
of innate immunity, and the development of specific immunity to
disease-related antigens.
The initial focus of this collaboration is a novel immune stimulant
and specific gene inhibitor combination that could be used to elicit
both non-specific and specific protection against anthrax and anthrax
toxin. This combination product was the subject of two recent joint
grant applications by the companies. The Juvaris and SomaGenics
groups envision further collaboration in the areas of infectious
disease and cancer.
In commenting on the collaboration, Juvaris' CEO Martin D. Cleary
stated "The extension of the Juvaris platform to using inhibitory
RNA opens up many interesting product opportunities, which we think
may be of interest to the venture community and potential corporate
partners. We are excited about this opportunity and our new collaboration
with SomaGenics, a recognized leader in the field of inhibitory
RNA."
SomaGenics' CEO Brian Johnston said "SomaGenics is very pleased
to initiate this collaboration with Juvaris. We feel the combination
of gene inhibition and immune stimulation technologies could provide
an important new approach for the treatment of infectious disease
in general and anthrax in particular. We are very impressed with
the Juvaris technology and look forward to the results of our joint
effort."
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 system provides
the opportunity to develop many disease-specific vaccine products,
for which there are significant unmet medical needs.
About SomaGenics
SomaGenics is an innovator in the area of RNA-based gene inhibitors,
a class of molecules that includes siRNAs, ribozymes, and the SomaGenics-proprietary
RNA Lassos. RNA Lassos are catalytic RNA molecules designed to hybridize
to target RNAs and ligate their own ends together, creating a topological
linkage to the target mRNA. Lasso-target complexes can inhibit gene
expression by physically blocking translation of the target RNA,
by preventing RNA processing, or by regulating splicing. RNA Lassos
have been successful in inhibiting gene expression in several model
systems.
Since Lassos, unlike ordinary antisense molecules, are circular
and highly structured, making them relatively resistant to degradation
by nucleases in biological fluids. Lassos can be allosterically
regulated, enabling them to respond to the environment and potentially
making them cell-specific. Lassos can be designed for very high
sequence specificity, responsive to single nucleotide differences.
Finally, Lassos' lack of target cleavage allows them to redirect
splicing, where ribozymes and siRNAs are much less useful since
they cleave all splice variants to which they bind.
To address the problem of identifying the best target sites for
Lasso, antisense, or siRNA action, SomaGenics has developed proprietary
methods for producing libraries of inhibitors, called directed libraries,
which contain all possible sequences of a certain length occurring
within a given gene, gene family, or genome. SomaGenics has developed
efficient plasmid-based and viral vectors for delivering libraries
of inhibitors to cells as well as methods for selection of optimal
inhibitors based on phenotype.
SomaGenics' base technologies, including Lassos and library methods,
are covered by issued and pending patent applications in the major
international markets. The company has been awarded some 20 research
grants and contracts from the NIH, NSF, NASA, and DARPA to help
fund its early-stage research. Current areas of therapeutic development
include autoimmune disease, cancer, and anti-virals.
