Arius highlighted at AACR-NCI-EORTC 2007 International Cancer Conference

    Selected for oral presentation and two media highlight spots at AACR
    press conference

    TORONTO, Oct. 16 /CNW/ - ARIUS Research Inc., (TSX: ARI), a biotechnology
company discovering and developing the next wave of antibody therapeutics,
today announced that it has been selected to deliver a proffered paper in an
oral presentation on one of the six abstracts it will present at the
AACR-NCI-EORTC 2007 International Conference on Molecular Targets and Cancer
Therapeutics, held on October 22nd-26th in San Francisco. The Company will
deliver presentations that will disclose new findings related to its CD44,
TROP-2, CD59, CD9 and MCSP antibody programs. ARIUS scientists have also been
selected to discuss two of the Company's abstracts at the AACR press
    "The inclusion of six ARIUS abstracts, two media highlight spots and one
oral presentation in this year's AACR-NCI-EORTC conference is an important
accomplishment for our Company, reflecting the high quality of our research
and the scientific community's interest in our programs," said Dr. David
Young, President and CEO. "We are especially proud that our Trop-2 Signal
Transduction Program abstract was one of only 12 selected from more than
900 abstracts for presentation as a proffered paper. Being chosen for an oral
presentation slot at this important conference is a highly-regarded
achievement and will attract greater attention to our cancer drug portfolio."
    ARIUS scientists Dr. Amandine Truong, Ph.D. and Dr. Baldwin Mak, Ph.D.
will discuss the Company's findings for the following two abstracts at the
AACR press conference on Thursday, October 25th at 9:30 a.m. PT.

    Presentation PR12:

    "AR47A6.4.2, a functional naked monoclonal antibody targeting Trop-2,
demonstrates in vivo efficacy in human pancreatic, colon, breast and prostate
cancer models." Proffered Paper Session 3, Thursday, October 25, 2007 from
5:15 - 5:30 p.m. in the Third Floor Ballroom at Moscone Center.
    ARIUS' abstract and accompanying oral presentation examine the mechanism
of action of its Trop-2 targeting antibody. Trop-2 is a protein expressed on
the cell-surface and found in many cancer indications including pancreatic,
colon, breast and prostate cancer. The target is thought to be a key part of
the expansive MAPK pathway. The oral presentation will be delivered by Dr.
Amandine Truong, Ph.D., ARIUS Research Scientist.

    Abstract A70:

    "AR36A36.11.1, a monoclonal antibody targeting CD59, enhances complement
activity and exhibits potent in vivo efficacy in multiple human cancer
models." Session A, Tuesday, October 23, 2007, between 12:30-2:30 p.m. and
5:30-7:30 p.m.
    ARIUS' poster presentation discusses CD59, a widely expressed target in
malignant tumors that allows cancer cells to evade the immune system. ARIUS'
CD59 targeting antibody has the potential to help to activate the immune
system in addition to targeting cells directly. The target has been expressed
in a large number of cancer indications including breast, colon, lung and
