What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Part 1: Number of Participants With Dose-limiting Toxicities (DLTs)	Any adverse event that ws at least possibly related to study treatment and met protocol-specified criteria was classified as a DLT. For the purpose of dose finding, decisions on dose were based on DLTs observed during the first 21 days of treatment.	up to 3 weeks
Part 1: Number of Participants With Any Treatment-emergent Adverse Event (TEAE)	An adverse event (AE) was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. An AE therefore could have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as an AE that was either reported for the first time or the worsening of a pre-existing event after the first dose of either study drug until 104 days after the last dose of study treatment or the start of new anticancer therapy.	up to approximately 1 year
Part 1: Number of Participants With TEAEs Leading to a Dosing Modification (Treatment Interruption, Dose Reduction, and Permanent Discontinuation of Either Study Drug)	An AE was defined as any untoward medical occurrence associated with the use of a drug in humans, whether or not it was considered drug related. An AE therefore could have been any unfavorable or unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study treatment. A TEAE was defined as an AE that was either reported for the first time or the worsening of a pre-existing event after the first dose of either study drug until 104 days after the last dose of study treatment or the start of new anticancer therapy.	up to approximately 1 year
Part 2: Objective Response	Objective response was defined as the percentage of participants with a best overall response (BOR) of complete response (CR) or partial response (PR) by investigator assessment per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 (v1.1). CR: disappearance of all target and non-target lesions and no appearance of any new lesions. Any pathological lymph nodes (whether target or non-target) must have a reduction in the short axis to <10 millimeters (mm). PR: complete disappearance or at least a 30% decrease in the sum of the diameters of target lesions, taking as a reference the baseline sum diameters, no new lesions, and no progression of non-target lesions.	up to 2 years
