Brief summary

1. PFS by BICR, defined as the time from the date of randomization until the earliest date of disease progression as determined by BICR per RECIST v1.1, or death due to any cause, whichever occurs first, 2. OS, defined as the time from the date of randomization until death due to any cause.

Detailed description

Key Secondary 1. Objective response by BICR, defined as having a best overall response of CR or PR, as determined by BICR per RECIST v1.1., Secondary 2. DOR by BICR, defined as the time from the earliest date of CR or PR until the earliest date of disease progression, as determined by BICR per RECIST v1.1, or death due to any cause, whichever occurs first., Secondary 3. PFS by investigator, defined as the time from the date of randomization until the earliest date of disease progression, as determined by investigator assessment per RECIST v1.1, or death due to any cause, whichever occurs first., Secondary 4. Objective response by investigator, defined as having a best overall response of CR or PR, as determined by investigator assessment per RECIST v1.1., Secondary 5. DOR by investigator, defined as the time from the earliest date of CR or PR until the earliest date of disease progression, as determined by investigator assessment per RECIST v1.1, or death due to any cause, whichever occurs first., Secondary 6. AEs, assessed by physical examinations, evaluating changes in vital signs and ECGs, and through clinical laboratory blood sample evaluations., Secondary 7. Treatment interruptions, dose reductions, and discontinuation of study treatment due to AEs., Secondary 8. HRQoL, assessed by changes from baseline in EORTC QLQ-C30, EORTC QLQ-OV28, and EQ-5D-5L questionnaire scores
