Brief summary

1. Non-randomized Stage: Dose-limiting toxicity, 2. Non-randomized Stage: Incidence, nature, and severity of physical findings and adverse events, with severity determined according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5 (NCI CTCAE v5.0); for CRS, severity determined according to the American Society for Transplantation and Cellular Therapy (ASTCT) cytokine-release syndrome (CRS) grading criteria, 3. Non-randomized Stage : Change from baseline in targeted vital signs, 4. Non-randomized Stage : Change from baseline in targeted clinical laboratory test results, 5. Non-randomized Stage : Tolerability, as assessed by the incidence of dose interruptions, dose reductions and dose intensity, and treatment discontinuation not due to efficacy events, 6. ORR, defined as the proportion of patients whose best overall response is a PR or a CR during the study., 7. Randomized stage: Cumulative Area under the concentration-time curve (AUC) over Cycles 1-3 (AUCC1-3), 8. Randomized stage: Serum trough concentration at steady state, approximated by Cycle 4 (Ctrough, C4)
