Objective Response Rate (ORR)

The ORR was defined as the percentage of participants achieving complete response (CR) or partial response (PR) as assessed by the Investigator per Response Evaluation Criteria in Solid Tumors (RECIST) (version1.1), where CR=Disappearance of all target lesions. Any pathological lymph nodes must be \<10 millimeters (mm) in the short axis, PR=At least a 30 percent (%) decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters. Primary Analysis Population comprised of participants who received 3 or 4 prior lines of therapy (LOT), had homologous recombination deficiency positive (HRDpos) tumors, had platinum-sensitive disease, and were poly(adenosine 5'-diphosphate \[ADP\]-ribose) polymerase inhibitors (PARPi) naïve.

Duration of Response (DoR)

DoR was defined as the time from first documentation of CR or PR until the time of first documentation of disease progression (PD) as assessed by the Investigator per RECIST (version1.1). DoR was analyzed using Kaplan-Meier (KM) method.

ORR by HRD Status and Breast Cancer Gene (BRCA) Status

The ORR was defined as the percentage of participants achieving CR or PR as assessed by the Investigator per RECIST (version1.1), where CR=Disappearance of all target lesions. Any pathological lymph nodes must be \<10 mm in the short axis. PR=At least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters. ORR was evaluated for participants with following characteristics: HRD status (positive, negative and unknown) and BRCA status (mutation positive, wild-type and unknown).

Disease Control Rate (DCR)

Disease control rate was defined as the percentage of participants achieving CR, PR, or stable disease (SD) as assessed by the Investigator per RECIST (version1.1). The exact (Clopper-Pearson) method was used to calculate 95% confidence interval.

Progression Free Survival

Progression-free survival was defined as the time from the date of first dose to the earlier date of assessment of progression or death by any cause in the absence of progression as assessed by the Investigator per RECIST (version 1.1) or clinical criteria. Progression is defined using RECIST version1.1 as at least a 20% increase in the sum of the diameter of target lesions or unequivocal progression of existing non-target lesions or the appearance of one or more new lesions.

Overall Survival

Overall Survival was defined as the time from the date of the first dose to the date of death by any cause. It was calculated as (Date of Death minus First dose date plus 1) divided by 30.4375.

Up to 3 years

Time to First Subsequent Therapy (TFST)

Time to first subsequent therapy (TFST) was defined as the time from the date of first dose to the date of first subsequent therapy or death, whichever occurs first. It was calculated as (Earlier of \[First dose of first subsequent therapy or death\] minus First dose date plus 1) divided by 30.4375.
