Notably, when treated with multiplexed MAGEA1/PRAME TCR-T, the mice achieved longer lasting tumor control compared to TCR-T targeting a single antigen. Conclusions These findings support the hypothesis that multiplexed TCR-T mimics the natural oligoclonal T-cell response to cancer and has the potential to overcome antigen heterogeneity, which may contribute to the observed lack of durability in monotherapy TCR-T clinical trials.
