Adult B Acute Lymphoblastic Leukemia
Conditions
Brief summary
This is an open, single-arm, phase I/phase II clinical study to evaluate efficacy and safety of chimeric antigen receptor T cell immunotherapy (CAR-T) in the treatment of Relapsed Refractory (R/R) adult acute lymphoblastic leukemia bridging allogeneic hematopoietic stem cell transplantation.
Detailed description
This trial openly recruited 50 patients into the group and were given CAR-T treatment. Patients participating in clinical trials will be tested and evaluated in terms of treatment safety, efficacy, and response duration. As assessed by clinicians, adult B-ALL patients who meet the enrollment criteria, after adequate communication, the patient or family members voluntarily join the clinical study, and are willing to bridge allogeneic hematopoiesis within 3 months after enrollment using CAR-T therapy。
Interventions
CD19 CAR-T infusion for patients with CD19 positive tumor cells
CD22 CAR-T infusion for patients with CD22 positive tumor cells
CD19+CD22 CAR-T infusion for patients with CD19 positive and CD22 positive tumor cells
25mg/㎡ for D-4、D-3 and D-2
500mg/㎡ for D-3 and D-2
