Clinical Trial Summary

Serosal cavity metastases of malignant tumor seriously affects the quality of life and survival time of patients with cancers in advanced stage. VEGFR1 is frequently expressed in breast cancer, ovarian cancer, lung cancer, gastric cancer and other malignant tumors and their metastases. The VEGFR1/PD-L1 dual-targeting CAR-T will be investigated in cancer patients with serosal cavity metastases.


Description:

In this study, VEGFR1 will be used as the general target of serosal cavity metastasis of malignant tumor, and the dual-targeting CAR-T of VEGFR1/PD-L1 will be injected in to pleural or peritoneal cavity of patients with advanced serous cavity metastases, such as ovarian cancer, breast cancer, lung cancer and gastric cancer, who had nearly no response to standard treatment. The safety and effectiveness will be evaluated. The safety evaluation standard refers to the standard of CTCAE 5.0. The evaluation standard of effectiveness refers to the evaluation standard of solid tumor curative effect RECIST 1.1 to evaluate the curative effect. There are two part of this study, the first is dose escalation part, 18 patients with malignant tumor (failure of standard treatment will be enrolled at least, patients with peritonea cavity metastases are planned to be enrolled in the cohort 1, and those with pleural cavity metastasis are enrolled in the cohort 2. The second is dose expansion part, the curative effect has observed in the first part, and after the DLT observation period of the related dose group was finished, the PI will decided whether to conduct the dose expansion research finally. It was planned to enroll 40 patients with serous cavity metastases , two cohorts were divided the same as mentioned above in dose escalation part.

Patients have used immunosuppressive agents for a long time after organ transplantation, except for recent or current inhaled corticosteroid therapy; 11. The existing medical history or mental state history or laboratory abnormalities may increase the risk associated with participating in the study or the administration of the study drug from the point view of PI; 12.
