Group Intervention Description Prexasertib Cohort 1 Prexasertib Participants received 105 milligram per square meter (mg/m²) prexasertib as an approximately 60 (+10) minute IV infusion on Day 1 and 15 of a 28-day cycle. Participants were with platinum-resistant disease, breast cancer susceptibility gene (BRCA) negative and have received ≥3 lines of prior therapy. Prexasertib Cohort 2 Prexasertib Participants received 105 mg/m² prexasertib as an approximately 60 (+10) minute IV infusion on Day 1 and 15 of a 28-day cycle. Participants were with platinum-resistant disease, BRCA negative and have received \<3 lines of prior therapy. Prexasertib Cohort 3 Prexasertib Participants received 105 mg/m² prexasertib as an approximately 60 (+10) minute IV infusion on Day 1 and 15 of a 28-day cycle. Participants were with platinum-resistant disease, BRCA positive and received a prior poly ADP ribose polymerase (PARP) inhibitor. Prexasertib Cohort 4 Prexasertib Participants received 105 mg/m² prexasertib as an approximately 60 (+10) minute IV infusion on Day 1 and 15 of a 28-day cycle. Participants were with platinum refractory disease, BRCA positive or negative, no restriction on number of lines of prior therapy.
- Primary Outcome Measures
Name Time Method Percentage of Participants Who Achieve Complete Response (CR) or Partial Response (PR): Overall Response Rate (ORR) Baseline through Disease Progression (Up to 6 months) Overall response rate is the best response of complete response (CR) or partial response (PR) as classified by the independent central review according to the Response Evaluation Criteria In Solid Tumors (RECIST v1.1). CR is a disappearance of all target and non-target lesions and normalization of tumor marker level. PR is an at least 30% decrease in the sum of the diameters of target lesions (taking as reference the baseline sum diameter) without progression of non-target lesions or appearance of new lesions. Overall response rate is calculated as a total number of participants with CR or PR divided by the total number of participants per cohort with at least 1 measurable lesion, multiplied by 100.
- Secondary Outcome Measures
Name Time Method Pharmacokinetics (PK): Maximum Plasma Concentration (Cmax) of Prexasertib Cycle 1, Cycle 2, Cycle 4, Cycle 6 (Day 1 (End of prexasertib infusion (+15 min), 1-2 hours following end of prexasertib infusion), Cycle 2, day 1(Prior to start of prexasertib infusion) Pharmacokinetics(PK): Maximum Plasma Concentration of Prexasertib. The same dose was administered to Cohort 1, 2, 3 and 4 and were combined for analysis.
Disease Control Rate (DCR): Percentage of Participants With a Best Overall Response of CR, PR, or Stable Disease (SD) for at Least 4 Months Baseline through Disease Progression (up to 6 months) DCR is defined as the number of participants who achieve a best overall response of CR, PR or SD for ≥4 months as determined by per RECIST version 1.1. CR is the disappearance of all target and non-target lesions; PR is a ≥30% decrease in sum of longest diameter of target lesions without new lesion and progression of non-target lesion; SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease. Disease control rate is calculated as a total number of participants with CR or PR or SD divided by the total number of participants treated, then multiplied by 100.
Duration of Response Date of CR or PR to Date of Disease Progression or Death Due to Any Cause (up to 20 months) Duration of response is defined as the time from the date measurement criteria for CR or PR (whichever is first recorded) are first met until the first date that disease is recurrent or objective progression is observed, per RECIST 1.1, or the date of death from any cause in the absence of objectively determined disease progression or recurrence. Participants known to be alive and without disease progression will be censored at the time of the last adequate tumor assessment.
Percentage of Participants With at Least a 50% Reduction in CA-125 Levels From Baseline Baseline, 4 Weeks CA-125 response is defined as ≥50% reduction in CA-125 levels from a pretreatment sample. The response must be confirmed and maintained for ≥28 days according to GCIG criteria. Participants must have a pretreatment sample that is ≥2 times the upper limit of the reference range and obtained within 2 weeks before starting the treatment.
Progression-Free Survival Baseline to Disease Progression or Death from any Cause (Up to 22 months) Progression-Free Survival (PFS) is defined as the time from the date of enrollment until the first occurrence of documented disease progression per RECIST 1.1, or death from any cause in the absence of progressive disease (PD). Participants known to be alive and without disease progression will be censored at the time of the last adequate tumor assessment.
Overall Survival Baseline to Date of Death from Any Cause (Up to 26 months) Overall survival (OS) is defined as the time from the date of enrollment until death from any cause. If the participant is alive, lost to follow-up or withdrawn from study at the time of data analysis, OS data will be censored on the last date the participant is known to be alive.
