- Number of participants who experienced dose-limiting toxicities (DLTs) in Part 1 [ Time Frame: Up to ~2 cycles (6 weeks) ]The CTCAE, Version 5.0 will be used to grade the severity of AEs in this study. DLTs will be reported for Part 1 of this study.
- Number of participants who experienced an adverse event (AE) [ Time Frame: Up to ~6 months ]An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The number of participants who experienced an AE will be reported.
- Number of participants who discontinued study treatment due to an AE [ Time Frame: Up to ~6 months ]An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The number of participants who discontinued study treatment due to an AE will be reported.
- PFS [ Time Frame: Up to ~36 months ]PFS, defined as the time from randomization to the first documented disease progression per Lugano response criteria as assessed by BICR or death due to any cause, whichever occurs first will be presented.
- Overall survival (OS) [ Time Frame: Up to ~36 months ]OS, defined as the time from randomization to death due to any cause will be reported.
- Objective response rate (ORR) [ Time Frame: Up to ~36 months ]ORR, defined as the percentage of participants who achieve a complete response (CR) or partial response (PR) per Lugano criteria as assessed by BICR will be presented.
- Duration of response (DOR) [ Time Frame: Up to ~36 months ]DOR, defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first, will be reported.
