These data demonstrate that AB-2100 selectively targets tumors co-expressing PSMA and CA9, and can overcome multiple suppressive mechanisms in the TME. These results support the evaluation of AB-2100 in the clinic for the treatment of advanced or metastatic ccRCC.
Conclusions Preclinical data demonstrate that AB-2100 can selectively target antigens that cannot be safely targeted by conventional CARs, and overcome multiple suppressive mechanisms in the tumor microenvironment. These results support the evaluation of AB-2100 in the clinic for the treatment of advanced or metastatic ccRCC.
Furthermore, FAS/TGFBR shRNA containing ICTs demonstrated enhanced anti-tumor activity in multiple xenograft RCC models. Collectively, these results demonstrate that PSMA x CA9 ICT cells can (i) selectively target antigens that cannot be safely targeted by conventional CARs and (ii) overcome multiple suppressive mechanisms in the tumor microenvironment.
