Stellar Biotechnologies' Customer -- More Indications for KLH Use

PORT HUENEME, CA--(Marketwire - June 2, 2010) - Stellar Biotechnologies, Inc. (TSX-V: KLH) ("Stellar") is pleased to announce that its long-term customer, Neovacs SA - Paris (Paris Alternext: ALNEV), recently reached significant milestones in the development of its KLH conjugate vaccines using Stellar KLH as the critical vaccine carrier http://www.cancer.gov/drugdictionary/?CdrID=391254. Neovacs now has two vaccines in clinical trials using Stellar KLH. They have completed recruitment in a Phase I/II trial of a tumor necrosis factor alpha kinoid (TNF-K) in Crohn's disease and have dosed the first patient in a Phase I/II trial of an interferon-alpha Kinoid (IFN-K) in lupus patients http://en.wikipedia.org/wiki/Tumor_necrosis_factors. Neovacs' Kinoids are immunotherapies that stimulate an antibody response from the immune system to an inactivated cytokine http://en.wikipedia.org/wiki/Cytokine. This immune response aims to eliminate excessive levels of the cytokine targeted. Excessive cytokine production is implicated in multiple diseases, including autoimmunity and cancer.

Prior to this news, Neovacs had announced that it had entered Phase II human trials with a Stellar KLH-based vaccine for rheumatoid arthritis. http://www.medicalnewstoday.com/articles/173492.php

Stellar's Executive VP, Business Development & Finance Darrell Brookstein said, "Our customer's success in identifying additional indications that respond to KLH conjugate therapy bodes well for Stellar's plan to increase business development across a broad range of potential therapeutics and diagnostics. Both joint ventures and co-research partnerships will be keys to Stellar's advancement in the future, and we invite interest from companies and academic research centers. Our scientific and engineering team, combined with our long experience and intellectual property in KLH manufacture and source animal maintenance bring further value to our association."
