Primary Outcome Measures
NameTimeMethod
Number of subjects with dose limiting toxicities (DLTs)During the first three weeks

DLTs will be assessed during the first three weeks of treatment. DLTs are defined as toxicities that meet pre-defined severity criteria, and assessed as having a suspected relationship to study drug, and unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurs within the DLT observation period.

Number of subjects with adverse events (AEs)From the time of informed consent signed through 90 days after the last dose of study drug.

AE refers to any untoward medical occurrence or deterioration of existing medical event after the subject signed the ICF, whether or not considered related to the study treatment.

Objective Response Rate (ORR)Up to 2 years

ORR is defined as the proportion of subjects with CR or PR (based on RECIST Version 1.1).

Secondary Outcome Measures
NameTimeMethod
Overall survival (OS)Up to 2 years

OS defined as the time from the first dose to death from any cause.

Duration of response (DoR)Up to 2 years

Duration of response is defined as the duration from the first documentation of objective response to the first documented disease progression (based on RECIST Version 1.1) or death due to any cause, whichever occurs first.

Time to response (TTR)Up to 2 years

Time to response (TTR) is defined as the time from the start of the treatment to the first objective tumor response observed for patients who achieved CR or PR (based on RECIST Version 1.1).

Progression free survival (PFS)Up to 2 years

PFS is defined as the time from the start of treatment until the first documentation of disease progression or death due to any cause, whichever occurs first (based on RECIST Version 1.1).

Time to progression (TTP)Up to 2 years

Time to progression (TTP) is defined as the time from the start of the treatment to the documentation of disease progression (based on RECIST Version 1.1).

Disease control rate (DCR)Up to 2 years

DCR is defined as the proportion of subjects with CR, PR, or SD (based on RECIST Version 1.1).
