Amarillo Biosciences Plans a Human Influenza Clinical Trial in Perth, Australia

AMARILLO, TX--(Marketwire - August 2, 2007) - Amarillo Biosciences, Inc. (ABI) (OTCBB: AMAR) today announced that it has agreed to conduct human influenza research with Dr. Manfred Beilharz, Chair of Microbiology and Immunology, School of Biomedical, Bimolecular and Chemical Sciences, The University of Western Australia. "We have been collaborating with Dr. Beilharz for more than 10 years," said Dr. Cummins, CEO of ABI. "During that time, Dr. Beilharz has published 10 scientific papers or abstracts on the low-dose, oral use of interferon. We are pleased to extend our research collaboration with Dr. Beilharz. His exciting discoveries regarding how oral interferon can protect against influenza are critically important as the world prepares for the next influenza pandemic," said Dr. Joseph Cummins.

Recent publications from Freiburg, Germany by scientists (Grimm, et al. Proceeding National Academy of Sciences, April 2007) and from (Tumpey, et al. the Centers of Disease Control (CDC) and Prevention in Atlanta, J Virology, July 2007) report that a single dose of interferon placed in the nose of mice reduces mortality from 50% to 0% (CDC) or 100% to 0% (Germany) in H5N1 ("Bird flu") influenza (CDC) or unique virulent influenza (Germany) infections.

"We published earlier in 2007 that interferon in the mouth protects mice against fatal influenza," said Professor Beilharz. "We used a concentration of interferon similar to that used by CDC and also reported that a dosage 100 times less was also protective against fatal influenza infection in mice. Our goal from new animal research is to determine the optimal dose and timing of administration of oral interferon so we can more carefully design human clinical trials. These human clinical trials will not only address the influenza issue, but will also address a new approach to winter colds and flu-like conditions," said Professor Beilharz.

Perth is a city in Western Australia with 2 million residents. The clinical study will be conducted there in childcare workers, school teachers and hospital workers who will be naturally exposed to infections of influenza and other respiratory pathogens. Some subjects will take placebo daily during the next "flu season" and others will take oral interferon at the dosages covered by ABI's issued U.S. patents. Besides ABI's patented dose formulation, two of ABI's issued U.S. patents have claims which directly apply to the low-dose oral use of interferon for influenza.
