Juvaris BioTherpeutics Expands Relationship
With Valentis
The Company Obtains Exclusive License to the DOTIM Lipid-DNA Complex
for Therapeutic Vaccines
Pleasanton, CA - June 4, 2004
Juvaris BioTherapeutics, Inc. announced today that they entered
into an exclusive licensing agreement with Valentis to use Valentis'
proprietary plasmid backbone in conjunction with Valentis' proprietary
DOTIM cationic lipid for the development and commercialization of
therapeutic vaccine products. Under terms of the agreement, Valentis
will receive cash payments from Juvaris and be eligible for future
product development milestones and royalties on sales. Juvaris will
be responsible for the development, manufacturing and commercialization
of products and will bear all related program expenses. Further
terms and financial considerations were not disclosed.
"Juvaris will use this proprietary lipid-DNA complex to up-regulate
the immune system as well as provide a vaccine platform for disease-specific
antigens. Our substantial preclinical data continues to support
this choice," said Martin D. Cleary, Co-founder, President and CEO
of Juvaris, and added "This is also an important step in advancing
our immunotherapeutic product development program. Valentis has
already generated clinical data with this plasmid and lipid and
Juvaris will benefit from the manufacturing, regulatory and related
data generated to date. This know-how will shorten our time to the
clinic and avoid delays in our product development strategy. I am
delighted we were able to come to this exclusive licensing agreement."
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.
