ARIUS announces cancer stem cell antibody program successfully completes first toxicology study
Date:10/23/2007

-Lead antibody targeting novel epitope of CD44 found in breast colon, and

prostate cancers-

TORONTO, Oct. 23 /PRNewswire-FirstCall/ - ARIUS Research Inc., (TSX: ARI), a biotechnology company discovering and developing the next wave of antibody therapeutics, today announced that the lead drug candidate from its CD44 Cancer Stem Cell program has successfully completed its first toxicology study and has shown good efficacy in animal models. ARIUS' program targets a novel epitope of CD44 that has been found in a number of cancer indications including breast, colon, and prostate cancers. Two humanized versions of the CD44 targeting antibody have been generated in preparation for the initiation of human clinical trials in 2008.

"To be effective against cancer, a treatment must eliminate the cancer stems cells that at the heart of the disease that are driving tumor growth and seeding new tumors," said Dr. David Young, President and CEO. "Our CD44 targeting antibody is one of the most advanced drug candidates to target cancer stem cells. CD44 is considered an especially attractive target for anti-tumor drug discovery and development because it has been identified as a cancer stem cell marker in breast, prostate and colon cancers. Having now successfully completed our initial CD44 toxicology study, we look forward to moving our CD44 antibody toward human clinical trials in 2008."

Toxicology Presentation

ARIUS has demonstrated that its antibody targets a novel epitope of CD44 that is present on the majority of human tumors. A dose-ranging pilot toxicology study in non-human primate models demonstrated no dose-limiting toxic effects at doses up to 95 mg/kg. Effects observed in healthy animals were minor and transient.

Additional information can be found at AACR-NCI-EORTC 2007 International Conference on Molecular Targets and Cancer Therapeutics in San Francisco at the following location and times: Abstract B41: "Toxicology and pharmacokinetics of chimeric ARH460-16-2, a therapeutic monoclonal antibody targeting CD44." Session B, Wednesday, October 24, 2007, between 12:30-2:30 p.m. and 5:30-7:30 p.m.

Efficacy Presentation

ARIUS' CD44 targeting antibody has demonstrated significant tumor growth inhibitory activity in in vivo animal models of breast, prostate, liver, and AML cancers. In breast cancer models, the antibody demonstrated tumor regression with increased survival at all doses. Two humanized versions of the antibody have been generated and their affinity is comparable to that of the chimeric and murine antibodies. The results of this study have also demonstrated the potential for the antibody to target the cancer stem cell antigen in breast cancer. The potency of the two humanized antibodies on tumor growth inhibition has been demonstrated in established tumor models in preparation for human clinical trials in 2008.

Session A, Tuesday, October 23, 2007, between 12:30-2:30 p.m. and 5:30-7:30 p.m.
