Drugs approved for treatment of liver cancer

Chimeric antigen receptor (CAR) T-cells that specifically target Fibroblast Growth Factor Receptor 4 (FGFR4), a surface tyrosine receptor that is extensively expressed in rhabdomyosarcoma (RMS), are now undergoing clinical research. However, the effectiveness of these CAR T-cells may be hindered by tumor heterogeneity and inadequate activation. In this study, we present a method to enhance the co-stimulatory and targeting characteristics of a FGFR4 CAR through an optimization process. We substituted the hinge and transmembrane domain of CD8 as well as the 4-1BB co-stimulatory domain with the corresponding domains of CD28. The CARs produced exhibit heightened anti-tumor efficacy in multiple RMS xenograft models, with the exception of the RMS559 cell line, which is known for its aggressive nature.
