The study will conduct dose-finding. The dose-finding will be set as 3+3 design to seek candidates for optimal doses. Patients will receive study drugs to determine the MTD and/or OBD. In this study, OBD is defined as the most reasonable dose considering the benefit/risk ratio from available non-clinical and clinical data. The OBD will be determined based on available safety, PK/PD, and preliminary efficacy data, with a focus on identifying the dose that optimally balances clinical activity and tolerability.
