Quigley Pharma Inc. Announces Continued Progress In Natural Broad Spectrum Anti-Viral For Use In Preventing Spread Of Avian Flu In Poultry Stocks

DOYLESTOWN, Pa. July 19 /PRNewswire-FirstCall/ -- Quigley Pharma, a wholly-owned subsidiary of The Quigley Corporation , announced today that it has obtained positive results that support Quigley Pharma's continued progress in developing the natural broad spectrum anti-viral QR-441(a) for use in preventing the spread of avian flu in poultry stocks. The results of the healthy chicken medical feed study confirm that food or water dose forms provide an opportunity for potential commercialization if the compound demonstrates efficacy within these dose forms.

The results clearly showed that the chickens tolerated and consumed all concentrations of QR-441(a) in the medicated feed. They also tolerated and consumed the low concentration of drug in the medicated water. Dr. Timothy Cummings, MS DVM, ACPV, Clinical Poultry Professor, College of Veterinary Medicine, Mississippi State University conducted the trial.

The Company is preparing to test QR-441(a) in chickens infected with H5N1 in challenge studies. These studies will center on the well-tolerated medicated food and water although other dose forms or delivery systems may be considered. To that end, the Company has developed challenge study protocols and has entered into preliminary agreements with several international research facilities that are qualified to conduct challenge testing with such highly infective pathogens. These proposed studies are in support of a previously assigned FDA INAD No. 011427 that allows Quigley Pharma to conduct further in-vivo chicken challenge studies.

"Follow up efficacy challenge studies will be conducted internationally for two reasons, primarily due to the fact that there are few domestic facilities willing to conduct chicken challenge studies with this highly infective pathogen, and secondly, to facilitate the broadest possible distribution in the event of positive results and an eventual outbreak," stated Dr. Richard Rosenbloom, COO, Quigley Pharma.

Should an outbreak of H5N1 occur in the United States, the federal and local government, working in conjunction with the poultry industry, will likely establish a hot zone where all poultry will be slaughtered. Immediately outside the hot zone will be a buffer zone perimeter in which poultry will be at a greater risk of infection by H5N1 than those further outside the hot zone. QR-441(a) is designed specifically for use in the buffer zone perimeter.

The Quigley Corporation makes no representation that the U.S. Food and Drug Administration or any other regulatory agency will allow the aforementioned Investigational New Drug to be marketed. Furthermore, no claim is made that the potential medicine discussed here is safe, effective, or approved by the Food and Drug Administration.
