Advaxis is based in Princeton, New Jersey. Advaxis focuses on commercializing the innovative vaccine technology developed by Dr. Yvonne Paterson in the Department of Microbiology at the University of Pennsylvania. Advaxis is developing therapeutic cancer vaccines that enhance the immune system's cancer-fighting abilities. Advaxis, through its proprietary Listeria Monocytogenes based system, is utilizing two immunological mechanisms (Innate and Classical Immunity) to develop safer and more effective cancer vaccines. Advaxis is the exclusive licensee of a patented broadly enabling innate immunity platform technology, which is based on the usage of the attenuated bacteria Listeria Monocytogenes, that, when combined with classical antibody and cellular immune mechanisms, can elicit more effective anti-tumor responses. Advaxis' lead vaccine candidate, Lovaxin C, targets cervical and head and neck cancers. Further vaccines in development target breast, ovarian and lung cancers.
