SIM0505 mono dose escalationEXPERIMENTALEvery 21 days is one cycle. Multiple dose levels of SIM0505 will be explored in dose escalation, and determine the maximum tolerated dose.
SIM0505 mono dose optimization - OvarianEXPERIMENTALEvery 21 days is one cycle. 2-3 dose levels of SIM0505 will be explored in dose optimization, and determine the recommended dose (RD) of SIM0505 and evaluate the preliminary anti-tumor activity of SIM0505 in ovarian cancer.
SIM0505 mono dose optimization - RenalEXPERIMENTALEvery 21 days is one cycle. 2 dose levels of SIM0505 will be explored in dose optimization, and determine the recommended dose (RD) of SIM0505 and evaluate the preliminary anti-tumor activity of SIM0505 in renal cancer.
SIM0505 mono dose optimization - USCEXPERIMENTALEvery 21 days is one cycle. 2 dose levels of SIM0505 will be explored in dose optimization, and determine the recommended dose (RD) of SIM0505 and evaluate the preliminary anti-tumor activity of SIM0505 in uterine cancer.
SIM0505 mono dose optimization - NSCLCEXPERIMENTALEvery 21 days is one cycle. 2 dose levels of SIM0505 will be explored in dose optimization, and determine the recommended dose (RD) of SIM0505 and evaluate the preliminary anti-tumor activity of SIM0505 in lung cancer.
