Generex Biotechnology Presented Data at The Endocrine Society's Annual Meeting

Study Demonstrates Value of Human Insulin Therapy

WORCESTER, MA, June 19, 2008 (PRIME NEWSWIRE) -- Generex Biotechnology Corporation (NasdaqCM:GNBT, www.generex.com), the leader in drug delivery for metabolic diseases through the inner lining of the mouth, made a podium presentation of data from a company-sponsored study at The Endocrine Society's 90th Annual Meeting (ENDO, www.endo-society.org <http://www.endo-society.org/> ) in San Francisco on June 18, 2008.

Doctor Jaime Guevara-Aguirre of the Institute of Endocrinology IEMYR, Quito, Ecuador, made a podium presentation of an abstract entitled, "Human Insulin Therapy is Safe, Efficacious, and Less Costly Than Insulin Analogs in the Treatment of Type-1 Diabetes." The abstract was co-authored by Doctor Jaime Guevara-Aguirre and Doctor Marco Guevara-Aguirre, both of the Institute of Endocrinology IEMYR; Professor Arlan L. Rosenbloom of the University of Florida; and Dr. Gerald Bernstein, the company's Vice-President for Medical Affairs.

The one-year study compared the efficacy and safety of analog versus human insulins. The study showed that human insulin administered as basal injection and with meals as orally absorbed regular insulin (Generex Oral-lynT, the company's proprietary oral insulin spray product) attained lower pre-meal glucose, HbA1c, and fructosamine concentrations when compared with a regimen using basal and pre-prandial insulin analogs in Type-1 diabetes. The cost of insulin analogs, basal and pre-prandial, is greater than that of recombinant human insulin, but this greater expense has been considered justified by therapeutic advantages. The study concluded that human insulin, when delivered through the buccal mucosa, is not inferior to analogues in the long-term treatment of Type-1 diabetes and could be used as a less costly alternative.

The company also made a poster presentation of an abstract entitled, "Serum Fructosamine Measurement is Adequate for Monitoring Long-Term Metabolic Control in Type-1 Diabetes." The abstract was co-authored by Doctors Jaime Guevara-Aguirre, Marco Guevara-Aguirre, and Jeannette Saavedra, all of the Institute of Endocrinology IEMYR, Quito, Ecuador; Edward Vidgen of the University of Toronto; Professor Arlan L. Rosenbloom of the University of Florida; and Dr. Gerald Bernstein, the company's Vice-President for Medical Affairs.
