Outcome Measures
Primary Outcome Measures
- Objective response rate (ORR) by independent central radiological review (IRC) according to RECIST 1.1. [Approximately 1.5 years]
ORR is defined as the proportion of participants with confirmed complete response or partial response by IRC according to RECIST 1.1.
Secondary Outcome Measures
- Duration of response (DOR) [Approximately 1.5 years]
DOR is defined as the time from date of the first objective tumor response (CR or PR) to the first documentation of either Progression of Disease (PD) or death due to any cause, whichever occurs first.
- Time to response (TTR) by IRC according to RECIST 1.1 [Approximately 1.5 years]
TTR is defined as the duration of time between the date of the first dose and the date of first documented response of either CR or PR.
- Progression-free survival (PFS) by IRC according to RECIST 1.1 [Approximately 1.5 years]
PFS is defined as time from the first dose until disease progression or death from any cause, whichever occurs first.
- Disease control rate (DCR) by IRC according to RECIST 1.1 [Approximately 1.5 years]
DCR is defined as the proportion of participants with BOR of CR or PR or stable disease (SD)
- CA19-9 response rate [Approximately 1.5 years]
CA19-9 response rate is defined as the proportion of participants with CA19-9 response (achieving ≥50% decrease in CA19-9 serum levels).
- Overall survival (OS) [Approximately 2.0 years]
OS is defined as time from date of the first dose to date of death due to any cause.
- Number of participants with adverse events [Approximately 1.5 years]
Participants will be assessed for incidence and severity of AEs according to NCI-CTCAE 5.0 criteria
