ImmuneRegen BioSciences, Inc. Announces First Study of Viprovex(TM) to Explore Adjuvant Capabilities in the Area of Pandemic Inf

GenPhar, a Leader in the Area of Vaccine Development for the Biodefense Industry, to Collaborate on the Studies 


SCOTTSDALE, Ariz., Jan. 4   /PRNewswire-FirstCall/ -- ImmuneRegen BioSciences, a wholly owned subsidiary of IR BioSciences Holdings, Inc. (OTC:IRBO) (BULLETIN BOARD: IRBO) , today announced it has commenced the first study of Viprovex(TM) to explore its adjuvant capabilities in the area of Pandemic Influenza Vaccine.  The study is being conducted in conjunction with privately-held vaccine developer GenPhar, Inc., of Charleston, SC.  GenPhar began its biodefense program in 2000 as one of the first in the industry and now works closely with the Department of Defense.  GenPhar has vaccines for lethal viruses such as Ebola, Marburg, dengue and influenza, with several approaching the final development and testing stages prior to approval.

"We are very happy to announce our relationship with GenPhar which has developed a promising portfolio of vaccines and are excited to begin generating data in this very relevant area.  If we can confirm immunostimulatory adjuvant activity in conjunction with an effective vaccine against Avian Influenza, we can help vaccinate many more Americans helping limited amounts of vaccine provide more effective, perhaps global coverage," said ImmuneRegen's CEO Michael Wilhelm.  "GenPhar's vaccine development program is aggressively achieving milestones against viruses such as HIV, hepatitis B and C virus, influenza, and potential bioterror agents such as the hemorrhagic fevers caused by Ebola and Marburg virus, and dengue fever.  We are very pleased to be working with such a well-established and respected scientific team, and believe that positive results with Viprovex(TM) will also open up the possibilities to include Viprovex(TM) into other vaccines against diseases with great social and economical impacts, such as HIV and hepatitis C and can be followed up with additional studies further demonstrating adjuvant capabilities."

Radilex is the trade name used in referring to formulations of Homspera for potential indications for treatment of exposure to ionizing radiation. Viprovex is the trade name used in referring to formulations of Homspera for potential indications for treatment of viral and bacterial infections. Homspera is a generic name used by the Company to describe the synthetic peptide Sar9, Met (O2)11-Substance P.
