Conditions: PD-1 Antibody; CAR-T Cells; Advanced Malignancies

Summary: to evaluate the safety and effectiveness of cell therapy using herincar-pd1 cells to treat advanced cancer. individuals greater than or equal to 18 years of age and less than or equal to 70 years of age who have been diagnosed with relapsed or refractory cancer that has not responded to or has relapsed after standard treatment.

a total of 20 patients may be enrolled over a period of 1-2 years.
