Amarillo Biosciences is a biotechnology firm operating in global partnership with the Hayashibara Group, which also holds 20.6 percent of Amarillo Biosciences shares and has provided more than $16.5 million in loans, grants and equity investments. The company's primary focus is extensive and ongoing research and development into the use of low-dose, orally administered interferon as a treatment for a variety of conditions, including Sjogren's syndrome, Beh et s disease, and opportunistic infections in patients who are HIV positive. In its 20-year history, the company has invested almost $37 million to establish oral interferon as a therapeutic agent. The overwhelming majority of those funds were invested in clinical trials in an effort to achieve Federal Drug Administration approval for interferon.
