Generex Announces Podium Presentation on Antigen Express Cancer Vaccine Strategy 2013 Immunotherapies Congress in Boston

WORCESTER, Mass. and TORONTO, Aug. 13, 2013 /PRNewswire/ -- Generex Biotechnology Corporation (www.generex.com) (OTCBB: GNBT) today announced that Dr. Eric von Hofe, Ph.D., President of its wholly-owned subsidiary, Antigen Express, Inc. (www.antigenexpress.com), will be making a presentation at the Emerging Cancer Immunotherapies and Vaccines conference that is being held as part of the 2013 Immunotherapies Congress in Boston August 13-14.  The conference brings together leaders in both academia and industry, focusing on next-generation targets and strategies for cancer immunotherapy.  Using lessons learned from early cancer vaccines and immunotherapeutics, a new wave of programs are underway that promise improved efficacy and safety over a wider range of cancers.  Emerging Cancer Immunotherapies and Vaccines will examine new targets and strategies in this space, along with important studies in preclinical development associated with developing these programs into successful drug products.

The presentation, entitled 'Augmenting Antigen-Specific CD4+ T Cell Activation in Cancer Immunotherapy', will highlight the significance of activating this particular cell type in the context of immunotherapy strategies designed to inhibit immune suppressive effects.  Examples of this strategy include PD-1 inhibitors and the recently approved CTLA4 inhibitor Yervoy®.

"While some approaches focus on taking the brakes off the immune system in a non-specific way, our strategy with AE37 is to step on the gas to specifically target tumor cells," commented Dr. von Hofe.  A wealth of accumulating evidence from both the clinic and research laboratories underscores the importance of specifically activating CD4+ T cells for effective cancer immunotherapy.

The presentation coincides with a conference call on August 14 featuring members of the Antigen Express Scientific Advisory Board, key opinion leaders who will discuss recent advances in cancer immunotherapy relevant to the positioning of the Antigen Express lead product AE37 as well as the proprietary Ii-Key technology platform upon which it is based.

Antigen Express was founded on a proprietary technology platform capable of generating a robust response against nearly any target one desires the immune system to recognize.  The most advanced compound based on this platform, AE37, is currently in a late Phase II clinical trial to establish efficacy in preventing relapse in patients who have had breast cancer. Results from an interim analysis conducted in October of 2011 were highly encouraging.  Based on those results, the Company has been encouraged to submit a Phase III protocol by the FDA.  Primary efficacy data is anticipated this fall.

About Generex Biotechnology Corporation

Generex is engaged in the research, development, and commercialization of drug delivery systems and technologies. Generex has developed a proprietary platform technology for the delivery of drugs into the human body through the oral cavity (with no deposit in the lungs). The Company's proprietary liquid formulations allow drugs typically administered by injection to be absorbed into the body by the lining of the inner mouth using the Company's proprietary RapidMist™ device. Antigen Express, Inc. is a wholly owned subsidiary of Generex. The core platform technologies of Antigen Express comprise immunotherapeutic vaccines for the treatment of malignant, infectious, allergic, and autoimmune diseases. Antigen Express has pioneered the use of specific CD4+ T-helper stimulation technologies in immunotherapy. One focuses on modification of peptides with Ii-Key to increase potency, while a second relies on inhibition of expression of the Ii protein. Antigen Express scientists, and others, have shown clearly that suppression of expression of the Ii protein in cancer cells allows for potent stimulation of T-helper cells and prevents the further growth of cancer cells.
