Clinical Trial Summary

The goal of this clinical trial is to estimate the safety, tolerance and initial efficacy of target IL-13Rα2 or B7-H3 UCAR-T cell injection in the treatment of patients with advanced glioma, as well as the pharmacokinetic characteristics of its metabolites after single and multiple administrations and the biomarkers related to efficacy, safety and drug metabolism.
