Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Dose limiting toxicity (DLT)	DLT is defined as a toxicity (adverse event at least possibly related to LM302) occurring during the DLT observation period	Cycle 1 of each cohort. Duration of one cycle is 21 days
Primary	Adverse Events and Serious Adverse Events	The safety profile of LM-302 will be assessed by monitoring the adverse events (AE) per the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0	From signing the ICF until 28 days after EOT or accept other anti-cancer therapy
Primary	Recommended Phase II Dose (RP2D)	The RP2D will be determined during the dose expansion stage of the study. RP2D will be determined using available safety and efficacy data	up to 21 days following first dose
Primary	Maximum Tolerated Dose (MTD)	The MTD is defined as the dose of which the toxicity rate during the DLT observation period (21 days after the first administration in cycle 1 on day 1).	up to 21 days following first dose
Secondary	Area under plasma concentration vs time curve (AUC) for LM-302	changes in AUC over time in participants with LM-302	Up to finished cycle 5 (each cycle is 21 days)
