Stellar Biotechnologies -- Independent KLH Toxicity & Immunogenicity Tests Complete

PORT HUENEME, CA--(Marketwire - November 30, 2010) -  Stellar Biotechnologies, Inc. (TSX-V: KLH) (PINKSHEETS: SBOTF) www.StellarBiotechnologies.com announces completion of preclinical toxicity and immunogenicity testing of Stellar KLH/SUBUNIT and Stellar KLH/IMG by independent laboratory, WuXi AppTech of St. Paul, MN (a wholly owned subsidiary of WuXi PharmaTech) in two preclinical studies, setting the stage for use of Stellar KLH/IMG in human studies.

Dr. Herbert Chow, VP Product Development, said, "Use of Stellar KLH as a potent adjuvant for immune stimulation, must be accomplished without causing increased susceptibility to infections, autoimmune reactions or immune suppression. The assessment of immunogenicity and immunotoxicity are therefore important steps for demonstrating safety in preclinical studies. In two separate pre-clinical studies, we have confirmed that Stellar KLH products, both our IMG and SUBUNIT forms, possess potent immune stimulatory effects with no observed safety or immunotoxicity problems. The data demonstrate the superiority of Stellar KLH/IMG as a dynamic adjuvant, and will support the regulatory filings leading to testing it in human studies."
