ImmuneRegen BioSciences Prepares for Department of Health and Human Services RFP for Therapeutics to Treat Acute Radiation Syndrome

June 21, 2005

SCOTTSDALE, AZ – Research and development bio-pharmaceutical company, ImmuneRegen BioSciences, a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTC Bulletin Board: IRBO), announced today that it is preparing to respond to the Department of Health and Human Services (DHHS) Request for Proposals on the general topic of Acute Radiation Sickness (ARS). The DHHS recently announced they anticipate releasing a draft Request for Proposals for industry comment by July 2005. ImmuneRegen plans to include the latest findings on the efficacy of Radilex™ in treating the negative effects of toxic radiation exposure in their response.

"Our response will show that after seven rounds of animal testing for ARS using lethal dosages of radiation and reaching a 50% survival rate, there is little doubt that Radilex™ has incredible potential to save lives in the event of a terrorist attack,” states co-founder and CEO Michael Wilhelm. "We believe we will show our methods of action do not simply neutralize the attacking agent, but actually increase immune system activity, thereby allowing the body's own immune system architecture to repair itself.”

Once issued, ImmuneRegen will file a formal response to the RFP respective to its compound Radilex™ currently in development for treating the negative effects of toxic radiation exposure, including ARS. Recent testing of Radilex™ using Total Body Irradiation (TBI) showed a 50% survival rate among irradiated mice treated with Radilex™ Post Lethal Exposure (PLE).

This RFP is another step under the U.S. Government’s Project BioShield to uncover effective new treatments for ARS. Project BioShield is legislation enacted by Congress and signed into law by the President to provide incentives and dedicated funds to encourage private industry to develop original medical technology to meet the Nation's bio-terrorism defense needs. Under a provision known as an Emergency Use Authorization, the RFP data will be used by DHHS in the procurement of new medical counter-measures for the Strategic National Stockpile, in advance of formal FDA approval. ImmuneRegen BioSciences has begun preparations to produce the compound on a large scale should such potential purchases of Radilex™ occur. The company's current production of Radilex™ is manufactured under GMP standards.
