Official title
Intervention of Ovarian Cancer Based on Engineered Immune Effectors (EIEs)
Overview
This is a single-arm, open-label, phase I/II trial to evaluate the safety and efficacy of ovarian cancer specific cytotoxic lymphocytes (OC-CTLs) in women.
Detailed description
Ovarian cancer is a cancer that forms in or on an ovary. The majority of ovarian cancers arise from the epithelium (outer lining) of the ovary. In 2015 it was reported found in 1.2 million women and resulted in 161,100 deaths worldwide. Among women it is the seventh-most common cancer and the eighth-most common cause of death from cancer. Treatment for ovarian cancer consists of surgery, chemotherapy, immunotherapy and sometimes, radiotherapy. The kind of treatment depends on many factors, including the type of ovarian cancer, its stage and grade, as well as the general health of the patient.
Adoptive immunotherapy with cytotoxic T lymphocytes (CTLs) reactive with specific viral antigens has proven to be effective. Here, the investigators aim to evaluate the safety and efficacy of multiple infusions of ovarian cancer specific cytotoxic T lymphocytes in patients.
Interventions
- Biological OC-CTLs
2 to 4 infusions, once a week, for 1x10\^5\~4x10\^6 CTLs/kg via IV, abdominal cavity or tumor injection each time
Primary outcome measures
- Safety of OC-CTLs in patients using CTCAE version 4.0 standard to evaluate the level of adverse events [Time frame: 6 months]
Secondary outcome measures (2)
- Functional analyses of OC-CTLs in vitro [Time frame: 4 weeks]
- Anti-tumor effects [Time frame: 1 year]
