Brief Summary

In this single-center, single-arm,prospective, open-label, phase 1/2 study, the safety and efficacy of autologous CD70 targeted chimeric antigen receptor modified T (CAR-T) cell therapy will be evaluated in patients with CD70 antigen positive advanced/metastatic solid tumors . In this clinical trial, at least 12 eligible patients in dose escalation period will be enrolled to receive 3 doses of CD70-CAR cell therapy according to the "3+3" principle. In dose expansion period, additional at most 21 eligible patients will be enrolled to receive CD70-CAR-T cell therapy at dose of recommended phase 2 dose(RP2D).
