Percentage of Participants With Confirmed Objective Response (OR) as Assessed by Blinded Independent Central Review (BICR) |
For participants with solid tumors, except metastatic Castration Resistant Prostate Cancer (mCRPC), OR was defined as a complete response (CR) or partial response (PR) per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1), both confirmed by repeat assessments performed no less than 4 weeks after the criteria for response were first met. For participants with mCRPC, OR was defined as the percentage of participants with a best overall soft tissue response of CR or PR per RECIST v1.1 with no evidence of confirmed bone disease progression per Prostate Cancer Working Group 3 (PCWG3) criteria. Per RECIST v1.1, CR was defined as complete disappearance of all target and non-target lesions with the exception of nodal disease. PR was defined as greater than or equal to 30% decrease under baseline of the sum of diameters of all target measurable lesions. Non-target PR lesions must be non-Progressive Disease (PD), where PD was unequivocal progression of pre-existing lesions. |

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) |
An adverse event (AE) was any untoward medical occurrence in a clinical investigation where participants administered a product or medical device. TEAEs were those events with onset dates occurring during the on-treatment period. A Serious Adverse Event (SAE) was any untoward medical occurrence at any dose that: resulted in death, was life threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, or resulted in congenital anomaly/birth defect. A treatment-related AE was any untoward medical occurrence attributed to the study drug in a participant who received study drug. TEAEs were graded by the investigator using National Cancer Institute Common Toxicity Criteria for Adverse Events (NCI CTCAE) v4.03 as Grade 1 = mild; Grade 2 = moderate; Grade 3 = severe; Grade 4 = life-threatening; Grade 5 = death related to AE. |

On-treatment period was defined as the time from the first dose of study treatment through minimum (30 days + last dose of study treatment, start day of new anti-cancer drug therapy - 1 day). |

Number of Participants With Different Status for Defects in BRCA1, BRCA2 and ATM |
Participants were enrolled in the two cohorts based on BRCA 1/2 and ATM defect status assessed by the local laboratory. The participant BRCA and ATM status was assessed retrospectively by central laboratory, that may differ from the status assessed by the local laboratory. The ATM participants with a negative ATM status per the central laboratory were reported to have a positive ATM status per the local laboratory. Therefore, participants with negative ATM status might have been included in the ATM defect cohort. For defects in BRCA1, BRCA2 and ATM by central laboratory analysis, participants were classified as positive, negative, not analyzable or missing. The number of participants in each category of BRCA 1 defect, BRCA 2 defect, BRCA 1 or BRCA 2 defect and ATM defect were presented. |

The TMB category 'Not analyzable' included participants with available samples but not evaluable. The TMB category 'Missing' included participants with no sample available. The number of participants in each category at only baseline were tabulated. |
