PORT HUENEME, CA--(Marketwire - October 13, 2010) - (TSX-V: KLH) (PINKSHEETS: SBOTF) -- Stellar Biotechnologies, Inc. ("Stellar" or "the Company") has been advancing on several fronts over their first quarter as a public company, and expects to achieve new milestones before year end. The Company would like to comment on the recent, featured CBS Evening News report (see video link below) by Dr. Sanjay Gupta on a KLH-based glioblastoma vaccine in development by Celldex Therapeutics that they have received inquiries about.

On October 4th CBS Evening News with Katie Couric featured Dr. Sanjay Gupta in a story about a KLH-based brain cancer vaccine being tested in patients at Duke University for Celldex Therapeutics (the 3 minute video is available here: http://www.cbsnews.com/video/watch/?id=6927121n&tag=related;photovideo, a short article here: http://www.acsh.org/factsfears/newsID.1920/news_detail.asp).

John S. Sundsmo, Ph.D., Stellar's VP of Research & Intellectual Property Management, said, "Molecular biology is identifying genetic modifications in certain cancer cells that constitute targets for cancer vaccines. Dr. Sanjay Gupta discusses the initial successes observed with glioblastoma multiforme (GBM), normally a rapidly progressing form of brain cancer. The cancer vaccine in the report was produced by Celldex Therapeutics by coupling a cancer-specific protein onto the immune carrier protein KLH. The very early stage results for some patients show signs in MRIs that their tumors may have decreased. While the immune system is highly effective in protecting us against bacteria, cancer cells are extremely difficult to kill and effective killing is mediated by a specialized class of killer T-cells. In this respect, KLH, the hemocyanin protein from the giant keyhole limpet, can be seen as rather unique. KLH stimulates highly effective cell-mediated immunity that results in the production of cancer-killing T-cells. This is offering new hope for patients with previously incurable cancers." Discussions between Celldex and Stellar have been underway.
