IRBS IR BioSciences Holdings Inc New (CE)

ImmuneRegen BioSciences Inc.®, a wholly owned subsidiary of IR Biosciences Holdings Inc. (OTCBB: IRBS), ends 2009 with a significantly deeper understanding of the mechanisms underlying the demonstrated immunostimulatory activity of its development candidate Homspera®, and additional partners and advisory members who strengthen the Company's efforts to bring Homspera into human testing.

Relationships forged over the past 3 calendar quarters have included those with investigators at the University of Rochester and the University of Pittsburgh, and the Company has entered into a joint licensing agreement with the latter in the area of cancer vaccine adjuvants. Both investigators have subsequently joined the Company's Advisory Board and continue to support the Company's research and grant submission activities.

With the support of those investigators as well as others, multiple grant submissions have been made to NIH and BARDA (Biomedical Advanced Research and Development Authority) , as well as through the Armed Forces Institute of Pathology and Walter Reed Army Medical Center through their Combat Wound Initiative Program. NIH-funded studies in areas related to Idiopathic Pulmonary Fibrosis, where the Company has filed its first IND (Investigational New Drug application) with the U.S. Food and Drug Administration (FDA), are being pursued at the University of Rochester. Also, additional studies in Avian Influenza (H5N1) as well as the currently pandemic Swine-originated Influenza A virus (H1N1) have shown Homspera's efficacy in animal models in reducing the impact of infection with these potentially debilitating viruses.

Successful research studies have garnered the interest of potential partners, among them the world-renowned peptide manufacturer Bachem Inc., at which Homspera is being manufactured in compliance with current Good Manufacturing Practice (cGMP) standards. This material will be used in the necessary safety studies that will be submitted to FDA to support advancement of Homspera into initial human testing, which is planned to begin in late 2010.

"We are quite pleased with the company's progress over the past 12 months. Our team has worked extremely diligently to advance our work with Homspera with the hope this translates to great value for our shareholders," said ImmuneRegen CEO Michael Wilhelm.
