Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: LM-302 Dose Escalation at different dose levels; LM-302 Dose Escalation. 6 dose levels were pre-defined, and the initial accelerated titration followed by the i3+3 design was adopted during phase I.	Drug: LM-302 Injection; LM-302 Injection with dose escalation stage of different dose levels, as well as dose expansion stage with recommended dose level from dose escalation stage.
Experimental: LM-302(RP2D) Dose Expansion; LM-302 Dose Expansion, RP2D will be selected for dose expansion, with the aim to further evaluate the preliminary anti-tumor activity, safety and tolerability, etc.	Drug: LM-302 Injection; LM-302 Injection with dose escalation stage of different dose levels, as well as dose expansion stage with recommended dose level from dose escalation stage.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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
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
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
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 Outcome Measures

Outcome Measure	Measure Description	Time Frame
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)
