Trial outcomes

Primary outcomes

1

Maximum tolerated dose (MTD)

MTD is defined as the maximum dose level at which ≤1 patient have dose limiting toxicities (DLTs) during the DLT observation period, and it should be determined with 6 evaluable patients.

Time frame
Up to 3 years
2

Number of participants with Dose Limiting Toxicities (DLTs)

Severity of adverse events as assessed by the National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) v5.0.

Time frame
From first dose of study treatment until the end of Cycle 1 (each cycle is 21-days)
3

Number of participants experiencing adverse events (AEs)/serious adverse events (SAEs)

Number of participants with incidence of adverse events and with serious adverse events including changes from baseline in laboratory parameters, vital signs, Electrocardiogram (ECG), and physical examination, etc.

Time frame
From time of information consent to 30 days post last dose, up to 3 years
