CAR-T Immunotherapy Targeting CD19- ALL

Summary

This study will evaluate safety and efficacy of a combination of 4th generation chimeric antigen receptor gene-modified T cells targeting CD19 negative ALL that express CD22, CD123, CD38, CD10, CD20 and TSLPR, as many patients developed CD19-negative disease after CD19 CART immunotherapy. Clinical response and development of a standardized lentiviral vector and cell production protocol will be investigated. This is a phase I/II trial enrolling patients from multiple clinical centers.

4. The KPS score over 80 points, and survival time is more than 1 month.
5. Greater than Hgb 80 g/L.
