To evaluate simultaneous targeting of multiple tumor antigens, T cells expressing FL‐CAR were used to target EGFR, HER2, and CD38 expressed on breast cancer (MDA‐MB‐468 and HCC1954), ovarian cancer (OVCAR8), Burkitt Lymphoma (Ramos and Raji), and multiple myeloma (H929) cells (Figure 3A and Figure S9). The gene discussed is EGFR; the disease is neoplasm.
