About

This is a single arm, open-label, uni-center, phase I-II study to evaluate the safety and effectiveness of CAR-T/TCR-T cell immunotherapy in treating with different malignancies patients.

Full description

The study is a multi-target gene-modified immunotherapy. CAR-T/TCR-T cells include four different tumor-specific antibody.They are as following:anti-NY-ESO-1 antibody foresophagus cancer;anti-DR5 antibody for hepatoma;;anti-EGFR vIII antibody for hepatoma and glioma;anti-Mesothelin antibody for gastric cancer.

Enrollment: 50 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
