Chemokine Therapeutics Announces Positive Data Presented at the AACR Annual Meeting on Lead Product Candidate CTCE-9908

Posted on: Wednesday, 23 April 2008, 09:00 CDT

Chemokine Therapeutics Corp. ("Chemokine Therapeutics" or the "Company") (TSX: CTI)(OTCBB: CHKT), a biotechnology company developing chemokine-based therapies to treat cancer, blood disorders, and vascular disease today announced a poster was presented by Dr. Mark Basik, McGill University, at the American Association for Cancer Research (AACR) Annual Meeting held in San Diego, California. The poster showed positive CTCE-9908 data results in the treatment of breast cancer in a preclinical model.

The study by Dr. Basik used a mouse model that spontaneously forms breast cancer. These tumors develop and spread to the lungs at known developmental time points. Such models are prized in cancer research because the tumor is not a foreign tissue that is implanted in the animal. The results of the study showed that CTCE-9908 treatment by itself has an effect on reducing the tumor size in the breast and consistently reduced the number of metastases in the lungs by about one half. Also, adding CTCE-9908 to chemotherapy further inhibited the primary tumor compared to chemotherapy alone and supplementing CTCE-9908 to an anti-angiogenic drug similar to the cancer drug Avastin, further increased the efficacy of that therapy.

"We are excited by the potential of CTCE-9908 to enhance the efficacy of established chemotherapy as well as that of the emerging new generation of targeted cancer therapies on both the primary tumor and the metastatic process," stated Walter Korz, President and Chief Executive Officer of the Company.

The poster is available on the Company website at www.chemokine.net.

About CTCE-9908

CTCE-9908 is a peptide analog of the chemokine SDF-1, and an antagonist of its receptor, CXCR4. SDF-1 is the only known naturally occurring chemokine that binds to CXCR4, which is present on many cancer cells as well as cancer support cells such as cells making up new blood vessels. This binding process is believed to be critical in the SDF-1 induced cell migration. The anti-migration property of CTCE-9908 is pivotal in not only reducing recruitment of support cells that allow survival and growth of the primary tumor, but also metastasis (or spread) of cancer cells to distant locations in the body, where they form secondary tumors. Approximately 90% of cancer deaths are due to metastasis and disease progression. We believe that CTCE-9908 has the potential to shrink the primary tumor and delay the occurrence of new tumors due to its anti-angiogenic properties and anti-metastatic activity.
