Generex Provides Update on Antigen Express Phase II AE37 Breast Cancer Vaccine Trial

WORCESTER, Mass. and TORONTO, Feb. 17, 2015 /PRNewswire/ -- Generex Biotechnology Corporation (www.generex.com) (OTCQB: GNBT) today announced that results of the last pre-specified analysis of data from a Phase II study of a novel cancer vaccine designed to reduce the risk of relapse in patients who have had breast cancer corroborate qualitatively prior results from the primary analysis conducted in January of 2014. The Company plans to disclose the latest results from the Phase II clinical trial at this year's American Society of Clinical Oncology (ASCO) Annual Meeting to be held in Chicago from May 29 to June 2, 2015.  The ASCO Annual Meeting is the premier annual oncology symposium, bringing together more than 25,000 oncology professionals from a broad range of specialties.  An abstract in respect of the results of the Phase II trial has been submitted to the ASCO Annual Meeting; per ASCO rules, the contents of those abstracts are embargoed pending the meeting.

The AE37 cancer vaccine is being developed by the Company's wholly-owned subsidiary, Antigen Express, Inc. (www.antigenexpress.com).  It is designed to stimulate a specific immune response against the patient's cancer cells, preventing relapse in patients who have been treated for early stage breast cancer.

The recent analysis is based on data from 301 patients, making this the largest controlled and randomized trial of a breast cancer vaccine conducted to date. Similar to prior analyses, high-risk patients who are ineligible to receive the drug Herceptin (e.g., triple negative breast cancer) appear to benefit from AE37.  Triple negative breast cancer patients in particular represent a population of significant unmet need.

The immunotherapeutic AE37 is designed to work indirectly by stimulating the patient's immune system to recognize and kill cancer cells.  An advantage of AE37 is that it potently activates a subclass of immune cells, known at CD4+ T cells, to recognize the tumor-specific HER2 protein.  This subclass of T cell has been shown to be critical in generating a robust, long-lasting and effective immune response.  AE37 consists of a fragment of the tumor-associated HER2 protein modified by a proprietary platform technology developed by Antigen Express scientists.

The Company has been encouraged by the FDA to submit a protocol for a Phase III study of AE37.  In addition to breast cancer, the Company has also completed a Phase I trial of AE37 in patients with prostate cancer.  Along with cancers of the breast and prostate, a variety of other cancers such as ovarian, colon, and lung cancer similarly express some level of HER2 and may be considered for future AE37 trials.

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.
