WebThe treatment was well tolerated without on-target off-tumor toxicity but did not achieve objective clinical responses. Abstract The reprogramming of a patient’s immune system through genetic modification of the T cell compartment with chimeric antigen receptors (CARs) has led to durable remissions in chemotherapy-refractory B cell cancers. WebTumor antigen-specific T cells of autoantigens isolated from cancer patients usually have low affinity due to central tolerance. 85 As observed with CAR-T cells, the “on-target, off-tumor” response occurs when TCR-T cells are infused, due to the expression of the same antigen on normal tissue, and the infused TCR-T cells also induce the occurrence of …
