To study the safety and clinical effects of intratumor injecting CpG-ODN and in situ release of tumor antigen by interventional ablation or drug-eluting beads to treat advanced solid tumors.

Tumor infiltration lymphocytes (TILs) have been harvested from advanced cancer patients and constructed to knockout PD1 gene and express scFvs against both PD1 and CTALA4 and CARs against various antigens, followed by transfusion into the patients. The safety, tolerance, and preliminary clinical efficacy of the TILs will be evaluated.

T effector cells and NK cells have mutual compensatory killing functions on various of cancer types. For those cancers that have no available targets for CAR-T cell generations, we established potent T cell-like NK cells (ITNK) with a specific conversion protocol for the T cells from the patient, to perform anti-cancer therapy, especially for those cancers that are lack of MHC-I molecule expression. We have finished pre-clinical investigations for the ITNK cell therapy and scheduled to start a clinical phase I study.
