ARIUS Receives Six Key US Patents

Strengthens Intellectual Property Portfolio on Lead Programs and Antibody
Assets

TORONTO, Nov. 28 /CNW/ - ARIUS Research Inc. ("ARIUS" or the "Company")
(TSX: ARI) announced today that it has received Notices of Allowance from the
United States Patent and Trademark Office for patents on their lead antibody,
ARH460-16-2, targeting the CD44 antigen implicated as markers of cancer stem
cells in breast and prostate cancer plus separate patents covering antibodies
to the CD63, CD59 and MCSP antigens.
These patents are important additions to the ARIUS Intellectual Property
portfolio that underlie the value of existing partnerships and ongoing
business development and licensing activities. ARIUS has licensing and
collaboration agreements with leading biotechnology and pharmaceutical
companies such as Genentech, Takeda and PDL Biopharma with a global potential
value to ARIUS of approximately $400 million plus royalties on sales. ARIUS
will be eligible for these milestone fees based on research activities,
clinical milestones, regulatory approvals and 1st commercial sales. The terms
include $10.7 million in upfront payments, equity investment and research
support funding.
These new patents cover the antibody molecules and various uses of each
antibody and other similar antibodies to treat cancers such as ovarian,
prostate and breast cancer. In addition, ARIUS has patent claims covering
epitopes or specific parts of a cancer antigen target. This patent approach
represents a large step up in value over more general target coverage because
it is the epitope that determines what a cell will do when an antibody binds
to it. In ARIUS' case, functional antibodies bind to epitopes that signal a
cancer cell to die.
ARIUS has over 80 additional patents pending that will continue to
enhance the value of the Company and the strength of upcoming deals. The
Company actively applies for patents on additional technology, products, and
uses of products on an ongoing basis.
"Patents are crucial to being able to extract the value from the work
that we do and are one of the main reasons we are an attractive partner for
both large pharmaceutical and biotechnology companies," said Dr. David S.
Young, President and Chief Executive Officer of ARIUS. "Some of these current
patents represent a novel approach to cancer targets that is derived directly
from our FunctionFIRST(TM) Platform."
ARIUS has undergone a transformative year in 2006 with $28.5 million in
financing from leading life sciences investors such as Orbimed Advisors, Xmark
Opportunity Funds, and Efficacy Capital and graduated its listing to the
Toronto Stock Exchange. ARIUS is growing substantially and has augmented its
management and scientific team with leaders and experts in their fields.
ARIUS' proprietary FunctionFIRST(TM) technology platform uniquely creates
functional anti-cancer monoclonal antibodies that belong to a class of
revolutionary cancer drugs. ARIUS' functional antibodies are cytotoxic to
cancer cells but are non-toxic to their normal cell counterparts and are
validated through a number of commercial partnerships.
