Study Endpoints

Primary Endpoints

Number of Participants with Adverse Events (AEs)
Up to approximately 24 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.

Number of Participants Who Discontinue Study Treatment Due to an AE
Up to approximately 24 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.

Number of Participants Who Experience Dose-Limiting Toxicity (DLT)
Up to approximately 28 days

DLT is defined as any drug-related adverse event (AE) observed during the DLT evaluation period that results in a change to a given dose or a delay in initiating the next dose.

Objective Response Rate (ORR)
Up to approximately 24 months

ORR is defined as the percentage of participants who have a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). The percentage of participants who experience CR or PR as assessed by Blinded Independent Central Review (BICR) will be presented.

Number of Participants Who Experience an Adverse Event (AE)
Up to approximately 27 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.

Number of Participants Who Experience Dose Limiting Toxicity (DLT) (Part 1 Only)
Up to approximately 28 days

DLT will be defined as any drug-related AE observed during the DLT evaluation period that results in a change to a given dose or a delay in initiating the next dose.

Number of Participants Who Discontinued Study Intervention Due to an AE
Up to approximately 24 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.
