Spots Global Cancer Trial Database for Clinical Study of Autologous Stem Cell Transplantation + Anti-CD19 CAR T Cells for B-cell Lymphoma

Study Description

Brief Summary: To evaluate the CR rate of B-NHL subjects who achieved PR at intermediate assessment after first-line chemotherapy treated with autologous stem cell transplantation + Anti-CD19 CAR T cells.

Detailed Description: At present, the incidence of malignant hematological diseases represented by leukemia, lymphoma and multiple myeloma is increasing year by year, ranking in the top ten of tumor incidence and mortality, which greatly endangers people's health and social development . B-cell non-Hodgkin's lymphoma (NHL) is a common aggressive malignant lymphoma. Poor response of some patients to traditional first-line chemotherapy is one of the major problems facing this disease. As a result, researchers are using emerging tools such as high-throughput sequencing to further understand the nature of the disease, refine the classification of the disease, and on this basis develop personalized treatments to improve the prognosis of the disease. Lymphoma has a complex immunosuppressive microenvironment that may prevent CAR T from achieving sustained precision tumor killing. As a revolutionary immunotherapy strategy, CAR-T therapy is currently faced with some bottleneck problems such as post-treatment relapse (including antigen loss relapse and antigen positive relapse), CAR-T consumption, off-target effect and so on. At present, autologous stem cell transplantation still plays a pivotal role in high-risk B-NHL. But at the same time, autologous stem cell transplantation is also faced with the age of patients, the influence of minimal residual disease (MRD) status before transplantation, chemotherapy dependence sensitivity, post-transplantation recurrence, post-transplantation granulosis infection and other problems. In this study, we explored the efficacy and safety of autologous stem cell transplantation combined with Anti-CD19 CAR-T cells in the treatment of B-cell NHL in patients with B-NHL who achieved partial response (PR) in the interim assessment after 3-4 courses of first-line therapy.
