Arm Intervention/treatment
Experimental: 1/OLAPARIB
olaparib 300mg oral tablets; twice daily
Drug: OLAPARIB
300 mg olaparib tablets taken orally twice daily. All patients should continue to receive study treatment until objective radiological disease progression as per RECIST 1.1 as assessed by the investigator or the patient experiences unacceptable toxicity or they meet any other discontinuation criteria.

Active Comparator: 2/CHEMOTHERAPY
Physician's choice single agent chemotherapy
Drug: Single agent chemotherapy
Treatment of relapsed disease with single agent chemotherapy based on physician's choice of weekly paclitaxel, topotecan, pegylated liposomal doxorubicin, or gemcitabine. All patients should continue to receive study treatment until objective radiological disease progression as per RECIST 1.1 as assessed by the investigator or the patient experiences unacceptable toxicity or they meet any other discontinuation criteria




Primary Outcome Measures :
  1. Objective Response Rate (ORR) [ Time Frame: Maximum of 45 Months ]

    Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria was used by a Blinded Independent Central Review (BICR) to assess participant response to treatment

    Objective Response Rate (ORR) is the number of participants with Complete Response (CR) or Partial Response (PR) in the Measurable Disease Analysis Set (MDAS). Complete response is declared when all lesions have disappeared or all lesions have disappeared and all nodal disease is < 10 mm each. Partial response is declared when there is a decrease in sum of diameters of target lesions ≥ 30%.



Secondary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Maximum of 45 Months ]
    RECIST 1.1 criteria was used to assess participant response to treatment. PFS was defined as the time from randomization until the date of objective radiological disease progression according to RECIST 1.1 or death (by any cause in the absence of disease progression) regardless of whether the participant withdrew from randomized therapy or received another anti-cancer therapy prior to disease progression (i.e., date of RECIST progression/death or censoring - date of randomization +1).

  2. Time From Randomisation to Second Progression (PFS2) [ Time Frame: Maximum of 45 Months ]
    Time from randomization to PFS2 was defined as the time from the date of randomization to the earliest of the progression events subsequent to first progression or death. The date of second progression was recorded by the investigator and defined according to local standard clinical practice, and could involve objective radiological, clinical, cancer antigen-125 (CA-125) progression or death. CA-125 progression was assessed per Gynecological Cancer Intergroup (GCIG) criteria.

  3. Overall Survival (OS) [ Time Frame: Maximum of 45 Months ]
  4. Time To Earliest Progression By RECIST 1.1 Or Cancer Antigen (CA) -125 Or Death [ Time Frame: Maximum of 45 Months ]
    Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria was used to assess participant response to treatment. CA-125 progression was assessed per Gynecological Cancer Intergroup (GCIG).

  5. Time From Randomization To First Subsequent Therapy Or Death (TFST) [ Time Frame: Maximum of 45 Months ]
    TFST was defined as the time from the date of randomization to the earlier of first subsequent therapy start date or death.

  6. Time From Randomization To Second Subsequent Therapy Or Death (TSST) [ Time Frame: Maximum of 45 Months ]
    TSST was defined as the time from the date of randomization to the earlier of second subsequent chemotherapy start date following study treatment discontinuation, or death.

  7. Time From Randomization To Study Treatment Discontinuation Or Death (TDT) [ Time Frame: Maximum of 45 Months ]
    TDT was defined as the time from randomization to the earlier of the date of study treatment discontinuation or death.

  8. Duration of Response (DoR) [ Time Frame: Maximum of 45 Months ]
    Duration of response is the time from the first documentation of complete response (CR) or partial response (PR) until the date of progression or death, or the last evaluable RECIST assessment for participants that do not progress or progress after 2 missed assessments. Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria was used to assess participant response to treatment.

  9. Time to Response (TTR) [ Time Frame: Maximum of 45 Months ]
    TTR was defined as the time from randomization until the date of first documented response by Blinded independent central review (BICR) assessment.

  10. Mean Change From Baseline In Trial Outcome Index (TOI) Score [ Time Frame: Baseline (Day 1) to Week 48 (±1 week) ]
    The TOI score was derived from the sum of the scores of the 25 items included in the physical well-being (7 items), functional well-being (7 items), and additional concerns ovarian cancer subscale (11 items) of the FACT-O questionnaire Version 4. A negative change in score from baseline indicated a worsening in symptoms.

  11. Number of Participants Who Show an Improvement in TOI Score [ Time Frame: Baseline (Day 1) to Week 48 (±1 week) ]
    The TOI score was derived from the sum of the scores of the 25 items included in the physical well-being (7 items), functional well-being (7 items), and additional concerns ovarian cancer subscale (11 items) of the FACT-O questionnaire Version 4. TOI score ranges from 0 to 100, a higher score indicates a higher health-related quality of life (HRQoL). A change in at least 10 points was considered clinically relevant.

  12. Objective Response Rate (ORR) in Breast Cancer Susceptibility (BRCA) Gene Population by Blinded Independent Central Review (BICR) [ Time Frame: Maximum of 45 Months ]

    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).

    The number of participants with complete or partial response per Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria. Partial response is declared when there is a decrease in sum of target disease ≥ 30%. Complete response is declared when all lesions have disappeared or all lesions have disappeared and all nodal disease is < 10 mm each.


  13. Number of Participants Who Experienced Disease Progression or Death in BRCA Gene Population by Blinded Independent Central Review (BICR) [ Time Frame: Maximum of 45 Months ]

    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).

    Progressive disease was defined as at least 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum of study. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.


  14. Number of Participants Who Experienced Second Progression or Death (PFS2) in BRCA Gene Population [ Time Frame: Maximum of 45 Months ]
    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).

  15. Overall Survival (OS) in BRCA Gene Population [ Time Frame: Maximum of 45 Months ]

    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).

    OS in BRCA gene population was measured by the number of participants who died due to any cause.


  16. Number of Participants Who Discontinued Study Treatment or Died in BRCA Gene Population [ Time Frame: Maximum of 45 Months ]
    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).

  17. Number of Participants Who Received Subsequent Chemotherapy or Died in BRCA Gene Population [ Time Frame: Maximum of 45 Months ]
    BRCA gene population includes participants identified as having a deleterious or suspected deleterious variant in either of the BRCA genes using variants identified with current and future BRCA mutation assays (eg, gene sequencing and large rearrangement analysis).
