Actual Primary Completion Date : October 10, 2011
Estimated Study Completion Date : December 30, 2022

Arm Intervention/treatment
Experimental: 1

Olaparib is available as a film-coated tablet containing 150 mg or 100 mg of olaparib. Subjects will be administered study treatment orally at a dose recommended by Investigator.

Full dose: 300 mg twice daily (bid) or Reduced doses: 200 mg twice daily (bid) or 100 mg twice daily (bid).

The planned dose of 300 mg bid will be made up of two x 150 mg tablets twice daily, with 100 mg tablets used to manage dose reductions.

Drug: olaparib
Tablets Oral BID
Other Name: Lynparza

Drug: paclitaxel
175mg/m2 iv for up to 6 cycles (18 weeks)

Drug: Drug: carboplatin
AUC4 iv for up to 6 cycles (18 weeks)

Active Comparator: 2
paclitaxel iv and carboplatin iv
Drug: paclitaxel
175mg/m2 iv for 6 cycles (18 weeks) day 1 of 21 day cycle
Other Name: Taxol

Drug: carboplatin
AUC6 iv for 6 cycles (18 weeks) day 1 of 21 day cycle

Primary Outcome Measures :
  1. Progression Free Survival (PFS) [ Time Frame: Radiologic scans performed at weeks 9 and 18 (+/-1 week) and every 12 weeks thereafter relative to the date of randomisation until the primary analysis (approximately 20 months) ]
    PFS (based on independent central review) was defined as the time from randomisation until objective disease progression as defined by Response Evaluation Criteria In Solid Tumours (RECIST) v1.1 (≥20% increase in the sum of the diameters of target lesions from minimum, clinically significant progression in non-target lesions or the presence of a new lesion) or death (by any cause in the absence of progression).

Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Following disease progression, patients will be contacted every 12 weeks to assess survival status until the final analysis (approximately 50 months) ]
    OS was defined as the time from randomisation until death by any cause. Patients who had not died at the time of analysis were censored at the last date the patient was known to be alive.

  2. Percentage Change in Tumour Size [ Time Frame: Week 9 (+/- 1 week) ]
    The total tumour size was defined as the sum of the longest diameters of the target lesions. At week 9, the percentage change in tumour size was calculated as [(week 9 sum of target lesions - baseline sum of target lesions)/baseline sum of target lesions]*100 for each patient. Imputations were used for missing data where possible.
