PHOENIX, AZ--(Marketwire - May 28, 2009) - ImmuneRegen BioSciences, a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTCBB: IRBS), is announcing today the submission of an Investigational New Drug Application (IND) to the U.S. Food and Drug Administration (FDA) to begin human clinical testing of Homspera, an analog of the endogenous neurokinin Substance P. The company plans to evaluate Homspera initially as a treatment for Idiopathic Pulmonary Fibrosis, a condition for which there are no consistently effective drugs approved for human use in the U.S.

"This marks a major milestone in our efforts to explore the molecular mechanisms and capabilities of Homspera and its potential to treat a range of complications arising from damage to the immune system," commented ImmuneRegen BioSciences CEO Michael K. Wilhelm. "We are encouraged by the results of pre-clinical studies of Homspera and look forward to taking our research to this next important level," he added.

Idiopathic Pulmonary Fibrosis is a progressive interstitial lung disease characterized by scarring of lung tissue. Over time, the formation of scars replaces air sacs with fibrotic tissue, preventing the lung from effectively transferring oxygen into the bloodstream. The disease currently afflicts 5 million people worldwide and kills 40,000 annually, though these numbers are believed to be artificially low due to misdiagnosis (http://www.pulmonaryfibrosis.org/ipf.htm). Recent research suggests Pulmonary Fibrosis is a reaction to microscopic injury to the lung resulting from the inhalation of pollutants, radiation exposure, and other insults.

About Homspera

Homspera is an adult stem cell active compound that has been shown in study results to regenerate and strengthen the immune system and enhance wound healing. Originally identified as providing protection from the lethal effects of acute radiation exposure, Homspera has been shown to affect a number of immunological and non-immunological cell types via its receptor-binding activity at the neurokinin-1 receptor (NK-1R). Studies also demonstrate the compound's hematopoietic stem cell stimulatory activity as well as immunomodulatory and anti-inflammatory activity in a number of model systems. To date, the FDA has issued Pre-Investigational New Drug (PIND) numbers to two derivatives of Homspera: one for Radilex® as a potential treatment of acute radiation exposure, and the other for Viprovex® as a potential treatment for novel forms of influenza.
