This Phase 1, single-arm, open-label, multi-center, dose-escalation and -expansion study will evaluate the safety and tolerability of LYL797, ROR1-targeting CAR T cells, in adults with relapsed and/or refractory ROR1+ triple negative breast cancer (TNBC) and non-small cell lung cancer (NSCLC). The dose-escalation phase includes TNBC and NSCLC patients, and will investigate 4 dose levels to determine the recommended Phase 2 dose (RP2D). The dose-expansion phase will enroll both TNBC and NSCLC patients at the RP2D.
This study will evaluate the safety and tolerability of LYL797, a ROR1-targeted CAR T-cell therapy, in patients with ROR1+ relapsed or refractory triple negative breast cancer (TNBC) or non-small cell lung cancer (NSCLC). The first part of the study will determine the safe dose for the next part of the study, and will enroll TNBC and NSCLC patients. The second part of the study will test that dose in additional TNBC and NSCLC patients.
