ImmuneRegen BioSciences Responds to Department of Defense

Pacific Northwest National Laboratory Collaborates with ImmuneRegen to Propose Universal Protectant Study

SCOTTSDALE, Ariz., Jan. 17 /PRNewswire-FirstCall/ -- Research and development biotechnology company ImmuneRegen BioSciences, Inc. a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTC Bulletin Board: IRBO), today announced it has recently submitted the requested proposal to the Department of Defense (DoD) for the 2006 Medical Science And Technology (S&T) Chemical And Biological Defense Transformational Medical Technologies Initiative (TMTI). ImmuneRegen has submitted for this grant in collaboration with Pacific Northwest National Laboratory. The submission makes a case for the development of Homspera(TM), a proprietary compound, as a Universal Protectant based on a Common Pathogenic Pathway.

"We are encouraged by Pacific Northwest National Laboratory's support in our proposal," says ImmuneRegen CEO Michael Wilhelm. "We believe their unique experience and expertise in the areas of chemical, biological and radiological threats will enhance our research and directly address the objectives of public health and national security. The proposal is further validated by the international recognition of the excellence of the NIH-supported proteomics program at Pacific Northwest National Laboratory (PNNL)."

The collaboration with PNNL will enable ImmuneRegen to perform more in-depth studies on Homspera than were previously unavailable. Homspera is the name for ImmuneRegen's synthetic Substance P analog, Sar(9), Met (O2)(11)-Substance P. Substance P is a naturally occurring neuropeptide that can be found throughout the body, including in the nerves surrounding the airways of humans and several other species. ImmuneRegen's proposal references several past biological studies of Homspera including radiation studies, formalin exposure studies and viral studies, including exposure of experimental animals to Hong Kong influenza virus.

Past testing of Homspera has shown a 50% survival rate among irradiated mice (7.75 gray) treated Post Lethal Exposure (PLE). Additionally, ImmuneRegen researchers have found that Homspera preserves pulmonary structure and function after toxicant exposure and impacts immunomodulatory responses following respiratory virus exposure, decreasing morbidity and mortality in experimental animals.
