The overall purpose of this study is to explore the safety and therapeutic effect of CD30-targeted chimeric antigen receptor T(CAR-T) cells in the treatment of Refractory/Relapsed lymphocyte malignancies.
Chimeric antigen receptor (CAR)-modified T cells (CAR-T cells) have the capabilities to recognize tumor associated antigen and kill tumor cells specifically. CD30 is originally described as a marker of Hodgkin's and R-S cells in Hodgkin's lymphoma. CD30 antibody has been applied to treat lymphocyte derived malignancies. To explore the potency of CD30 in CAR-T therapy, this trial is designed and conducted to test the safety and efficacy of CD30-targeted CAR-T in Refractory/Relapsed lymphocyte malignancies.

RECRUITINGNumber of participants with adverse events
Therapy-related adverse events were recorded and assessed according to the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE, Version 4.0).
Time frame: 3 years
One-month remission rate
Response to CAR-T therapy was assessed on day 30 (±2), against the National Comprehensive Cancer Network (NCCN, Version 1.2015).
Time frame: 1 month
Overall survival
OS was calculated from the first CAR-T cell infusion to death or last follow-up (censored).
Time frame: 3 years
Event-free survival
EFS was calculated from the first CAR-T cell infusion to death, progression of the disease, relapse or gene recurrence, whichever came first, or last visit (censored).
Time frame: 3 years
Relapse-free survival
RFS was calculated from the first CAR-T cell infusion to relapse or last visit (censored).
Time frame: 3 years
Quantity of anti-CD30 CAR-T cells in bone marrow cells and peripheral blood cells
In vivo (bone marrow and peripheral blood) quantity of CAR-T cells were determined by means of flow cytometry.
Time frame: 3 years
Quantity of anti-CD30 CAR copies in bone marrow cells and peripheral blood cells
In vivo (bone marrow and peripheral blood) quantity of anti-CD30 CAR copies were determined by means of qPCR.
Time frame: 3 years
