Outcomes Module

Primary Outcomes

Measure	Description	Time Frame
Number of participants with adverse events and serious adverse events	The safety profile of LM061 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 screening up to 1 year
Dose-limiting toxicities (DLT)	DLT is defined as a toxicity (adverse event at least possibly related to LM061) occurring during the DLT observation period (the initial 21 days)	: Cycle 1 of each cohort. Duration of one cycle is 28 days
Change in Vital Signs-ear temperature	Change in vital signs-ear temperature will be measured after the subject has been fully rested.	Baseline (Week 0) through approximately 1 year after first administration of LM061
Change in Vital Signs-pluse rate	Change in vital signs-pluse rate will be measured after the subject has been fully rested.	Baseline (Week 0) through approximately 1 year after first administration of LM061
Change in Vital Signs-blood pressure	Change in vital signs-blood pressure will be measured after the subject has been fully rested.	Baseline (Week 0) through approximately 1 year after first administration of LM061
Change in Electrocardiogram (ECG)-RR interval	RR interval of 12-lead ECG will be performed in the supine position after the patients are fully rested at each timepoint for once. RR is the standard heart rate which calculated by 60 divided by heart rate.

Secondary Outcomes

Measure	Description	Time Frame
7. Area under the serum concentration versus time curve within one dosing interval (AUCtau)	To determine the pharmacokinetics (PK) profile of LM061 Single dose: pre-dose (within 30 minutes before administration), and 1 h, 3 h, 6 h, 8 h, 10 h, 12 h, 24 h, 36 h, 48 h, 72 h, 96 h after administration on C0D1; Multiple dose: pre-dose (within 30 minutes before administration) on C1D1, C1D8, and C1D15; pre-dose (within 30 minutes before administration), and 1 h, 3 h, 6 h, 8 h, 10 h, 12 h, 24 h after administration on C1D22; The timepoints of PK sample may be adjusted base on the human PK data. The blood samples for PK analysis will be collected as much as possible if the subjects end of treatment/early withdraw.
