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).

Interventions

Olaparib 300mg Olaparib tablets taken orally twice daily (except where this dose and formulation was previously not tolerated) until objective radiological disease progression as per RECIST 1.1 or as long as in the Investigator's opinion they are benefiting from treatment and they do not meet any other discontinuation criteria.

DRUGPlacebo

Placebo 300mg placebo tablets taken orally twice daily (except where this dose and formulation was previously not tolerated) until objective radiological disease progression as per RECIST 1.1 or as long as in the Investigator's opinion they are benefiting from treatment and they do not meet any other discontinuation criteria.

Primary

MeasureTime frameDescription
Efficacy: Progression-free Survival (PFS)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 (assessed upto 3.8 years)PFS (per RECIST 1.1) was defined as the time from randomisation until the date of Investigator assessed objective radiological disease progression or death (by any cause in the absence of disease progression). Objective progression (per RECIST 1.1) is defined as at least a 20% increase in the sum of the diameters of the target lesions and an absolute increase of \>5 mm, or an overall non-target lesion assessment of progression or a new lesion. Patients who have not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST assessment.

MeasureTime frameDescription
Efficacy: Time to Progression by Gynecologic Cancer Intergroup (GCIG) CriteriaAt 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 (assessed upto 3.8 years)Time to progression by RECIST or CA-125 or death is defined as the time from randomisation to the earlier date of RECIST progression or CA-125 progression or death by any cause. Patients without a CA-125 progression or a RECIST progression who are still alive at the time of analysis will be censored at the time of their last evaluable RECIST assessment and/or their last available CA-125 measurement, whichever is the earliest at the time of analysis. Patients that do not have any evaluable RECIST assessments or any CA-125 results post-randomisation will be censored at the date of randomisation
Efficacy: Time to First Subsequent Treatment Commencement (TFST)From follow-up i.e. 30 days after last dose of study medication till end of study (assessed every 12 weeks upto 3.8 years)TFST was assessed as time from randomisation to first subsequent treatment commencement or death if this occurs before commencement of first subsequent treatment. Any patient not known to have had a further subsequent therapy or death was censored at the last known time to have not received subsequent therapy
Efficacy: Time to Second Subsequent Treatment Commencement (TSST)From follow-up i.e. 30 days after last dose of study medication till end of study (assessed every 12 weeks upto 3.8 years)TSST was assessed as time from randomisation to second subsequent treatment commencement or death if this occurs before commencement of second subsequent treatment. Any patient not known to have had a further second subsequent therapy or death was censored at the last known time to have not received second subsequent therapy
Efficacy: Overall Survival (OS)From randomisation till Long-term follow-up (12-weekly beyond 30 days after last dose of study treatment) assessed upto 3.8 yearsOS was defined as the time from the date of randomisation until death due to any cause.

HRQoL was analysed using the FACT-O tool by mixed model for repeated measures (MMRM) analysis of the change from baseline in TOI score. FACT-O TOI is scored from O to 100 with higher scores denoting better quality of life. The higher the score, the better the HRQoL.

Outcome results

Primary

Efficacy: Progression-free Survival (PFS)

PFS (per RECIST 1.1) was defined as the time from randomisation until the date of Investigator assessed objective radiological disease progression or death (by any cause in the absence of disease progression). Objective progression (per RECIST 1.1) is defined as at least a 20% increase in the sum of the diameters of the target lesions and an absolute increase of \>5 mm, or an overall non-target lesion assessment of progression or a new lesion. Patients who have not progressed or died at the time of analysis were censored at the time of the latest date of assessment from their last evaluable RECIST assessment.

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 (assessed upto 3.8 years)

Efficacy: Change From Baseline in Health-related Quality of Life (HRQoL)

Health related quality of life (HRQoL) of Olaparib maintenance retreatment compared to placebo as measured by the Functional Assessment of Cancer Therapy - Ovarian (FACT-O) Trial Outcome Index (TOI) was determined. HRQoL was analysed using the FACT-O tool by mixed model for repeated measures (MMRM) analysis of the change from baseline in TOI score. FACT-O TOI is scored from O to 100 with higher scores denoting better quality of life. The higher the score, the better the HRQoL.
