Mesothelin-targeting T cells bearing a novel T cell receptor fusion construct (TRuC) exhibit potent antitumor efficacy against solid tumors.

ABSTRACT: T cell Receptor (TCR) Fusion Construct (TRuC®) T cells harness all signaling subunits of the TCR to activate T cells and eliminate tumor cells, with minimal release of cytokines. While adoptive cell therapy with chimeric antigen receptor (CAR)-T cells has shown unprecedented clinical efficacy against B-cell malignancies, monotherapy with CAR-T cells has suboptimal clinical efficacy against solid tumors, probably because of the artificial signaling properties of the CAR. TRuC-T cells may address the suboptimal efficacy of existing CAR-T therapies for solid tumors. Here, we report that mesothelin (MSLN)-specific TRuC-T cells (referred to as TC-210 T cells) potently kill MSLN+ tumor cells in vitro and efficiently eradicate MSLN+ mesothelioma, lung, and ovarian cancers in xenograft mous
