Amarillo Biosciences Supplies Oral Interferon for Australian Human Influenza Study

AMARILLO, TX--(Marketwire - April 15, 2009) - Amarillo Biosciences, Inc. (AMAR) (OTCBB: AMAR) today announced that the company shipped clinical supplies to Perth, Australia to be used in a human clinical study conducted by Associate Investigator Dr. Manfred Beilharz, Chairman of the Department of Microbiology and Immunology, School of Biomedical, Biomolecular and Chemical Sciences, The University of Western Australia . Healthy adult volunteers will be screened and enrolled this month and will given oral interferon or placebo starting May 4. This date was selected to allow up to 200 volunteers to start treatment prior to the June-August peak cold and flu season in Perth. The treatment will continue daily for 4 months. The study will determine if oral interferon supplied by AMAR will help reduce the incidence, duration and severity of naturally occurring colds and flu.

Dr. David Smith, Principal Investigator, said, "Interferon had been used as a treatment for respiratory viruses for many years but the Perth trial will use a lower dose that will be given orally rather than as a nasal spray or injection. This is a pioneering trial and the idea is that it gives a broad protection against a range of respiratory infections because it's aimed at boosting immunity rather than being directed at a specific virus. If we get the promising results expected, we'll be looking at this as a springboard for a larger trial that could change the way we look at preventing infections, and add a new weapon in our fight against a range of respiratory illnesses."

Dr. Beilharz said, "This important clinical trial was implemented because of the published reports that oral or intranasal interferon prevents and/or treats influenza in humans, mice, guinea pigs and ferrets. Since influenza virus is able to develop resistance against the anti-viral drugs on the market, we need to determine if this natural protein, interferon, in low oral doses, is an inexpensive non-toxic alternative to oseltamivir (Tamiflu) and other anti-viral drugs."

Dr. Joseph Cummins, President and CEO of AMAR, said, "A recent publication in the Journal of Virology reported that human interferon administered once a day (on days -1, 0, 1, 3, 5 and 7 after infection) in the nose of guinea pigs will block or reduce replication of flu virus in the upper airways and result in less severe pneumonia. This publication is additional compelling evidence that our low-dose interferon may offer a reasonable alternative to expensive, toxic antiviral drugs for influenza."
