AE37 is a novel Ii-Key Hybrid-based HER-2/neu Peptide Vaccine designed to train the immune system, independent of HLA-type, to track down cancer cells throughout the body and destroy them. The positive interim Phase 2b results, building upon completed pre-clinical and Phase I breast cancer studies, enables Antigen Express to move up the timing of key development and regulatory plans. In particular, the company will organize an End-of-Phase 2 meeting with the
Importantly, the majority of women with loco-regional breast cancer have low to moderate expressing HER2 tumors and currently are treated with chemotherapy and radiotherapy only. There is no approved targeted HER2 therapy for these women.
"We are excited and committed to move the AE37 cancer vaccine through the appropriate scientific and regulatory steps," commented
Phase I studies clearly identified the potential for AE37 to induce the immune system to focus on the HER2 protein through helper (CD4) and cytotoxic (CD8) immune cells in patients. The HER2 protein is expressed on a high percentage of cancers in the breast, prostate, ovaries, gastro-intestinal tract, and lung. In two Phase I trials, AE37 has demonstrated a good safety profile in both breast and prostate cancer patients.
The AE37 cancer vaccine has also completed a Phase 1 trial in prostate cancer demonstrating appropriate dosing and immune activation similar to that seen in the breast cancer trials. The Phase 2b breast trial results add to AE37's database on tolerability and safety and have raised the possibility of using AE37 early in prostate cancer therapy. With the Phase 2b breast cancer trial suggesting immune activation by AE37 could control breast cancer and seeing similar immune activation in the Phase I prostate trial, the Company is encouraged to move AE37 cancer vaccine more rapidly into larger clinical trials in men with newly diagnosed HER2 positive prostate cancer. These Phase 2 trials are being designed with leading oncologists in prostate cancer.
About AE37 and Ii-Key Hybrid Platform Technology
Antigen Express is a platform technology and product-based company developing proprietary vaccine formulations for large, unmet medical needs. The Company's Ii-Key Hybrid technology platform entails the modification of fragments of antigens to increase their potency in stimulating critical members of the immune response, known as CD4+ T helper cells. Incorporating the Ii-Key modification along with tumor-associated antigens can greatly enhance the immune system's ability to recognize and destroy cancer cells bearing any of the targeted antigens as well as increasing immunological memory.
The first product candidate utilizing the Company's novel Ii-Key Hybrid technology platform is a HER-2/neu Peptide Vaccine (AE37). This "off-the-shelf" cancer immunotherapy product candidate is easier and less costly to produce than comparable cell-based approaches. AE37 is derived from a peptide fragment of the human epidermal growth factor receptor 2 (HER2) oncoprotein, which is expressed in a variety of tumors including 75-80% of breast cancers as well as a high percentage of prostate, ovarian and other cancers. AE37 represents the only HER2-based peptide vaccine currently being studied in a randomized trial and its use is not restricted to patients with a particular type of human leukocyte antigen (HLA) peptide.

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.
