Outcome Measures
Primary Outcomes (4)
Part A: Objective Response Rate (ORR) According to Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
ORR was defined as the percentage of participants in the analysis population who had a Complete Response (CR: Disappearance of all target lesions) or a Partial Response (PR: ≥30% decrease in the sum of diameters of target lesions) per RECIST 1.1. ORR will be reported.
Up to approximately 24 months
Part B: Number of Participants Who Experience One or More Adverse Events (AEs)
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who experience an AE will be reported.
Up to approximately 27 months
Part B: Number of Participants Who Discontinue Study Intervention Due to an Adverse Event (AE)
An AE is defined as any unfavorable and unintended sign, symptom, disease, or worsening of preexisting condition temporally associated with study treatment and irrespective of causality to study treatment. The number of participants who discontinue study intervention due to an AE will be reported.
Up to approximately 24 months
Part B: Number of Participants Who Experience a Dose Limiting Toxicity (DLT)
A DLT is defined as an event with toxicity including the type, severity, time of onset, time of resolution, and the probable association with study treatment that are not due to pre-existing conditions as defined by the Common Terminology Criteria for Adverse Events Version 5.0 (CTCAE 5.0). Number of participants who experience a DLT per CTCAE 5.0 will be reported.
Up to approximately 3 Weeks
Secondary Outcomes (11)
