In-vivo CAR Ts for myeloma are going to come fast and furious. These products are engineering marvels.
ESO-T01 (EsoBiotec) is an anti-BCMA in-vivo CAR T that:
1) Delivers the CAR transgene to endogenous T-cells, reprogramming them to CAR T cells in situ
2) Overexpress CD47 to reduce phagocytosis
3) MHC class I knocked out to reduce GVHD
4) Once transformed to CAR T, has anti-BCMA variable domain (nanobody derived), CD8 hinge and transmembrane domain, 4-1BB costim domain, and CD3-zeta activation domain.
5) No lymphodepletion needed off-the-shelf
