DCR is defined as the percentage of participants with BOR of CR, PR, or stable disease (SD) based on investigator assessment using RECIST v1.1.

Duration of Response (DOR)Up to approximately 5 years and 10 months

DOR is defined as the time from the date of the earliest documented CR or PR (that is subsequently confirmed) to disease progression or death due to any cause, whichever occurs earlier, based on investigator assessment using RECIST v1.1. Only responders will be included in the assessment.

Progression Free Survival (PFS)Up to approximately 5 years and 10 months)

PFS is defined as the time (months) from the date of the first dose of combination treatment to disease progression or death due to any cause, whichever occurs first, based on investigator assessment using RECIST v1.1

Overall Survival (OS)Up to approximately 5 years and 10 months

OS is defined as the time from the date of the first dose of combination treatment to death due to any cause.
