SEATTLE (July 1, 2013) – Etubics Corporation, a bio-pharmaceutical company with a proprietary vaccine platform that stimulates a long lasting “active” immune response, announced today that it has received a grant of approximately $1.03 million from National Institute of Health (NIH) to research and develop a therapeutic vaccine for HIV/Human Papilloma Virus (HPV) associated oropharyngeal and tonsillar malignancy, or head and neck cancers (Grant#: 2R44DE021973-02).

The grant will support the necessary pre-clinical experiments to allow Etubics HPV immunotherapeutic targeting head and neck cancers to enter into clinical trials. The immunotherapeutic will target E6 and E7 proteins in HPV (HPV-E6/E7) and was shown to improve long-term survival in animal models. W hen used with chemotherapy or radiation, it was shown to statistically enhance the clearance of established HPV cancer in vivo and largely reduced tumor growth as compared with control mice. Etubics HPV-E6/E7 immunotherapeutic utilizes the Etubics Platform, which is stealth to the immune system and has the ability to deliver a long lasting “active” immune response against cancer targets, educating the immune system’s T-cells to act as if the cancer was a simple virus. HPV is responsible for as many as 100,000 cases of head and neck cancer worldwide per year. The majority of these are oropharyngeal and tonsillar cancers. In the United States, prevalence estimates of oropharynx HPV infection ranges from 9.2-18.6%. The incidence of tonsillar cancer in the United States has increased by two to three percent per year from 1973 to 1995. HIV-infected individuals have a two to six fold increase in the risk of developing oropharyngeal and tonsillar cancers.

These grants have helped to further Etubics colon cancer, breast cancer, HPV induced cancer and HIV vaccine programs.
