SCOTTSDALE, AZ--(Marketwire - April 27, 2010) - ImmuneRegen BioSciences Inc.®, a wholly owned subsidiary of IR Biosciences Holdings Inc. (OTCBB: IRBS), today announced a collaboration and research agreement with the Department of Tumor Immunology of the Radboud University Nijmegen Medical Centre (RUMC), in the Netherlands to commence studies utilizing ImmuneRegen's Homspera. Under the agreement top cancer vaccine experts at RUMC will perform exploratory studies on Homspera relating to its adjuvant and immunomodulatory properties for potential application in experimental cancer vaccines and immunotherapy for cancer.

Homspera has been shown to be effective in enhancing the efficacy of a novel cancer vaccine in an experimental melanoma model, and previous studies have demonstrated efficacy in enhancing immune responses to infectious disease vaccines, such as influenza. The studies to be performed at RUMC are designed to expand on that research, and further define the mechanisms that make Homspera an effective vaccine adjuvant.

The research will be directed by Professor Gosse Adema, Chair and full professor of Molecular Immunology in the Department of Tumor Immunology, Nijmegen Centre for Molecular Life Science. Professor Adema is also Theme Leader for Infection, Immunity and Tissue Repair. Dr. Adema has published over 150 scientific publications on scientific topics ranging from the role of dendritic cells in cancer immunology and cancer vaccines to the identification of cancer specific antigens. Other important RUMC Department of Tumor Immunology researchers who will participate in these studies with ImmuneRegen's Homspera include Dr. Jolanda de Vries and Professor Carl Figdor.

Radboud University Nijmegen Medical Centre is a leading academic centre with expertise in medical science and healthcare in the Netherlands. Scientific expertise plays an essential part in their organization and connects research, education and patient care. More than 8,000 staff and 2,500 students are committed and ambitious, helping to shape the future of healthcare and medical science.

"We are pleased that Professor Adema and his team are interested in evaluating the impact of Homspera in their cancer vaccine models, and hope this is the beginning of a long and fruitful relationship that takes our compound into a number of vaccine adjuvant, and perhaps other, studies," said Hal Siegel, Ph.D., ImmuneRegen's Chief Scientific Officer.
