Current Primary Outcome Measures  ICMJE
 (submitted: April 4, 2017)
Efficacy: Progression-free survival (PFS). [ Time Frame: At randomization visit and at every 12 weeks (+/- 7 days) until objective radiological disease progression as determined by the investigator or other discontinuation criteria are met. ]
PFS measured from the date of randomisation to the date of investigator assessed disease progression (according to RECIST version 1.1 criteria) or death from any cause (in the absence of progression).
Original Primary Outcome Measures  ICMJE Same as current
Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: April 4, 2017)
  • Efficacy: Overall survival (OS) [ Time Frame: From randomisation till Long-term follow-up (12-weekly beyond 30 days after last dose of study treatment) ]
    OS measured from the date of randomisation to the date of death from any cause.
  • Efficacy: Time to progression by Gynecologic Cancer Intergroup (GCIG) criteria [ Time Frame: At screening (Visit 1) and at every 12 weeks (±7 days), until objective disease progression, based on progressive serial elevation of serum CA-125 according to the GCIG criteria, or until discontinuation for other reasons. ]
    Time to progression measured from randomisation to the earliest of Investigator-assessed disease progression by RECIST or cancer antigen 125 (CA-125), or death (by any cause in the absence of progression).
  • Efficacy: Time to first subsequent treatment commencement (TFST) [ Time Frame: From follow-up i.e. 30 days after last dose of study medication till Long-term follow-up i.e. 12-weekly beyond 30 days after last dose of study treatment. ]
    This will be assessed by checking: - Time from randomisation to first subsequent treatment commencement or death if this occurs before commencement of first subsequent treatment.
  • Efficacy: Time to second subsequent treatment commencement (TSST). [ Time Frame: From follow-up i.e. 30 days after last dose of study medication till long-term follow-up i.e. 12-weekly beyond 30 days after last dose of study treatment. ]
    This will be assessed by checking: -Time from randomisation to second subsequent treatment commencement or death if this occurs before commencement of second subsequent treatment.
  • Efficacy: Time to study treatment discontinuation (TDT). [ Time Frame: From follow-up 30 days after last dose of study medication till long-term follow-up i.e. 12-weekly beyond 30 days after last dose of study treatment. ]
    This will be assessed by checking: - Time from randomisation to study treatment discontinuation or death if this occurs before discontinuation of study treatment.
  • Efficacy: Health-related quality of life (HRQoL) [ Time Frame: At Baseline, and from Day 1 till Long-term follow-up (12-weekly beyond 30 days after last dose of study treatment) ]
    HRQoL of olaparib maintenance retreatment will be compared against matching placebo as measured by the Functional Assessment of Cancer Therapy - Ovarian (FACT-O) Trial Outcome Index (TOI). The Change from baseline, time to deterioration and proportion improved will be recorded.
  • Safety and tolerability: Number of patients with Adverse Events (AEs), and Serious Adverse Events (SAEs). [ Time Frame: At Baseline and from Day 1 till follow-up i.e. 30 days after last dose of study medication. ]
    All AEs/serious adverse events (SAEs)reported during the study will be recorded.
  • Safety and tolerability: Number of patients with Adverse Event of Special Interest (AESI). [ Time Frame: At Baseline and from Day 1 till long-term follow-up i.e. 12-weekly beyond 30 days after last dose of study treatment. ]
    All AESIs reported during the study will be recorded.

Descriptive Information
Brief Title  ICMJE A Study to Examine Olaparib Maintenance Retreatment in Patients With Epithelial Ovarian Cancer.
Official Title  ICMJE A Phase IIIb, Randomised, Double-blind, Placebo-controlled, Multicentre Study of Olaparib Maintenance Retreatment in Patients With Epithelial Ovarian Cancer Previously Treated With a PARPi and Responding to Repeat Platinum Chemotherapy
Brief Summary The OReO study will be a Phase IIIb, randomised, double-blind, placebo-controlled, multicentre study to assess the efficacy and tolerability of Olaparib retreatment, versus matching placebo, in non-mucinous epithelial ovarian cancer (EOC) patients (including patients with primary peritoneal and/or fallopian tube cancer).
Detailed Description The OReO study will investigate the efficacy and safety of Olaparib maintenance re-treatment in patients with relapsed non-mucinous EOC, who have had disease progression following maintenance therapy with a Polyadenosine 5'diphosphoribose [poly (ADP ribose)] polymerisation inhibitor (PARPi) and a complete or partial radiological response to subsequent treatment with platinum-based chemotherapy or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy), and no evidence of a rising CA-125. Patients will be enrolled on the basis of their breast cancer susceptibility gene (BRCA1, BRCA2) status into one of two cohorts (BRCA1/2 [+ve] and BRCA1/2 [-ve]). The BRCA1/2 (+ve) and BRCA1/2 (-ve) cohorts will be randomised separately. Within each cohort, patients will be randomised by prospective allocation in a 2:1 ratio (Olaparib: matching placebo).
