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.
About Breast Cancer
According to the American Cancer Society, more than 232,000 women will be diagnosed with breast cancer, and nearly 40,000 will die from the disease, in 2011. For women whose cancer tests positive for increased quantities of the HER2, approved targeted therapies include trastuzumab (Herceptin®; Roche-Genentech). However, only 25% of breast cancer patients have HER2 levels high enough to be eligible for Herceptin. AE37 is positioned initially as an adjuvant therapy for at
