ImmuneRegen BioSciences, Inc. Demonstrates That Viprovex Is a Potential Treatment for Avian and Other Influenzas
SCOTTSDALE, Ariz., January 09, 2007 /PRNewswire-FirstCall/ -- ImmuneRegen BioSciences, a wholly owned subsidiary of IR BioSciences Holdings, Inc. , today announced results from tests conducted using Viprovex(TM), its proprietary compound, in a severe influenza treatment study. Tests evaluating ImmuneRegen's Viprovex(TM) as a measure in the possible treatment of influenza virus infection were conducted at Virion Systems, Inc. (VSI), a Maryland biotechnology corporation. Influenza studies were performed using a cotton rat (Sigmodon hispidus) model system with the influenza A/Wuhan/359/95 (H3N2), a robust, peer-reviewed model system for studying human influenza.
Management believes that preliminary results of Viprovex treatment of cotton rats infected with the H3N2/Wuhan human influenza virus provided indications that Viprovex may have positive effects on enhancing immunity against influenza infection and supports ongoing development of Viprovex as a potential treatment for seasonal influenza.
Viprovex treatment reduced nasal and lung titers one- to two- logs (90+ %) compared to infected but untreated controls. In addition, treated animals appeared to lose less weight than untreated infected animals and appeared to regain normal body weight more rapidly. Additionally, Viprovex treated animals appeared to have less change in body temperature then untreated animals.
Company officials believe that the preliminary data suggests that Viprovex could have positive effects in the treatment of influenza infection perhaps through the modulation of cytokine activation and in the enhancement of innate immunity to influenza. Additional studies are presently underway in this and other influenza model systems to confirm and expand these results.
