The highly potent and efficacious activity of SAR444200 in diverse models of GPC3+ tumors and the extremely wide tolerated dose range merits further development of this compound. Furthermore, NANOBODY®-based TCEs developed using an anti-TCRαβ moiety may have specific advantages for the development of TCEs.
Conclusions These preliminary results from the first two DLs suggest that SAR444200 is tolerable at the tested DLs in patients with advanced solid tumors. Dose escalation continues at this time.
