Intervention of Ovarian Cancer With Antigen-specific Engineered Immune Effectors
Interventional Treatment of Ovarian Cancer With Cancer Antigen-specific Engineered Immune Effector T Lymphocytes (OC-EIEs)
Study Overview
Detailed Description
Ovarian cancer (OC) is a cancer that is derived from an ovary. The majority of OC arises from the epithelium (outer lining) of the ovary. In 2015, OC was found in 1.2 million women and resulted in 161,100 deaths worldwide. Among women, OC is the seventh-most common cancer and the eighth-most common cause of cancer death. Treatment for OC consists of surgery, chemotherapy, immunotherapy and radiotherapy. The kind of treatment depends on many factors, including the type of OC, its stage and grade, as well as the general health of the patient.
Adoptive immunotherapy with cytotoxic T lymphocytes (CTLs) reactive with tumor antigens has proven to be effective against many types of cancer. OC has been shown to be highly immunogenic and therefore may respond well to innovative antigen-specific immunotherapy. Here, through cancer antigen screening and careful target antigen evaluation, the investigation aims to evaluate the safety and efficacy of multiple infusions of OC antigen-specific, engineered immune effectors (EIEs) in patients with OC.
