Spots Global Cancer Trial Database for CD70 Targeted CAR-T Cells in CD70 Positive Advanced/Metastatic Solid Tumors

Study Description

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).

Detailed Description: Currently, CAR-T cell therapy has already achieved tremendous success in the treatment of hematological malignancies,however, it remains a severe challenge to treat solid tumors due to multiple obstacles,such as absence of tumor specific antigens, complex immunosuppressive tumor microenvironment, and tumor heterogeneity. CD70 is a member of the tumor factor superfamily and has been found to be highly expressed on the surface of several solid and hematological tumors, correlating with inferior prognosis.Targeting CD70 has emerged as potential novel immunotherapeutic strategy. Investigators have developed CD70-CAR-T cells that could effectively expand and survive，producing strong anti-tumor effects in animal models. Based on the preclinical data, we conduct this clinical trial in order to test the the safety profiles and anti-tumor activities of CD70-CAR-T cells in vivo. In dose escalation period, at least 12 eligible patients will be enrolled and receive 3 doses of CD70-CAR-T cell therapy (1 × 10\^6 cells/kg, 3 × 10\^6 cells/kg, 1 × 10\^7 cells/kg) 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 infusion at dose of RP2D, which is determined by data from dose escalation period, including occurrence of dose limiting toxicities (DLT), pharmacokinetics/pharmacodynamics, efficacy and other parameters, to furtherly evaluate the safety and efficacy profiles of CD70-CAR-T cell therapy.
