Study Endpoints
Primary Endpoints
Percentage of Participants with a Dose Limiting Toxicity (DLT)
Up to approximately 21 days

A DLT is defined as the occurrence of protocol-specified toxicities if assessed by the investigator to be possibly, probably, or definitely related to study intervention administration, excluding toxicities clearly not related to the drug.

Percentage of Participants who Experience at Least One Adverse Event (AE)
Up to approximately 84 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.

Percentage of Participants who Discontinue Study Intervention Due to an AE
Up to approximately 84 months

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention.

Objective Response Rate (ORR) per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 as assessed by Blinded Independent Central Review (BICR)
Up to approximately 84 months

ORR is defined as the percentage of participants with Complete Response (CR: disappearance of all target lesions) or Partial Response (PR: at least a 30% decrease in the sum of diameters of target lesions) per RECIST 1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented.

Secondary Endpoints
Duration of Response (DOR) per RECIST 1.1 as assessed by BICR
Up to approximately 84 months
Progression Free Survival (PFS) per RECIST 1.1 as assessed by BICR
Up to approximately 84 months
Overall Survival (OS)
Up to approximately 84 months
