Car T Cell Therapy Ncbi

Factors related to the efficacy and toxicity of car t cell therapy.

Car t cell therapy ncbi. 18 related to targeting malignant and normal b cells via cd19 depletion the following side effects can be observed. Crs ranging from low grade symptoms to life threatening multiorgan failure rarely evolving into hemophagocytic lymphohistiocytosis hlh macrophage activation syndrome mas. Like other technologies car t cell therapy has undergone a long development process and persistent explorations of the actions of the intracellular signaling domain and ma. 1 6 allogeneic hematopoietic cell transplantation allo hct is often offered to all patients to consolidate.

In a phase 1 trial axicabtagene ciloleucel axi cel an autologous anti cd19 chimeric antigen receptor car t cell therapy showed efficacy in patients with refractory large b cell lymphoma after the failure of conventional therapy. As summarized in table 1 car t cell therapy has shown impressive efficacy in b cell malignancies with a complete response cr rate of 81 90 for b all and of approximately 50 for b nhl 15 19 the cellular kinetics of car t cells and tumor burden are two important factors affecting the efficacy of car t cell therapy in. A phase 1 clinical trial of 19 28z car t cells after high dose therapy and autologous stem cell transplantation in 11 patients with relapsed or refractory aggressive b cell nhl showed that 4 of 10 evaluable patients remained alive and progression free from 13 to 21 months posttransplant. Cars are fusion proteins of a selected single chain fragment variable from a specific monoclonal antibody and one or more t cell receptor intracellular signaling domains.

Cd56 car t cell therapy is a safe and effective approach and may be an option for children with solid tumors who are nonresponsive to conventional radiotherapy and chemotherapy or are unsuitable for hematopoietic stem cell. Anti cd19 chimeric antigen receptor car t cell therapy is effective in patients with advanced b cell acute lymphoblastic leukemia b all. Other approaches to using gene therapy to enhance antitumor immunity have been less specific and less effective. However efficacy data is sparse in subgroups of patients with high risk features such as bcr abl tp53 mutation extramedullary disease including central nervous system leukemia or posttransplant relapse.

Car t cell therapy is associated with significant acute toxicities which can be severe or even fatal. Patient was in complete remission at last follow up visit after 3 5 years. Treatment with autologous cd19 specific chimeric antigen receptor t cell car t therapy has shown promising efficacy in patients with relapsed or refractory acute lymphoblastic leukemia all b cell non hodgkin lymphoma nhl and chronic lymphocytic leukemia cll.
