Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Olaparib
Treatment: Drugs - Cediranib

Experimental: Olaparib and Cediranib - Patients will receive oral olaparib 300mg twice daily and oral cediranib 20mg once daily.
Patients will attend hospital for a 2 weekly review for the first 8 weeks, then 4 weekly for year 1 and 8 weekly for year 2 onwards until discontinuation of all trial drugs. Treatment may continue beyond progression until the next line of treatment if the patient is deemed to still be deriving clinical benefit. Quality of life instruments will be collected at baseline, every clinic visit and continue to be completed after relapse.

Active Comparator: Olaparib - Patients will receive oral olaparib 300mg twice daily.
Patients will attend hospital for a 2 weekly review for the first 8 weeks, then 4 weekly for year 1 and 8 weekly for year 2 onwards until discontinuation of all trial drugs. Treatment may continue beyond progression until the next line of treatment if the patient is deemed to still be deriving clinical benefit. Quality of life instruments will be collected at baseline, every clinic visit and continue to be completed after relapse.

Treatment: Drugs: Olaparib
Olaparib is a PARP inhibitor, targeting DNA repair processes.

Treatment: Drugs: Cediranib
Cediranib is an inhibitor of vascular endothelial growth factor-A (VEGF), targeting angiogenesis.

Strategies to monitor adherence to the intervention or active comparator include participant diaries.

Usual therapy would consist of observation therefore the experimental and active comparator arms are in addition to usual therapy.

Minimisation will be used to allocate patients to either treatment arm, with stratification factors as follows:
1. 6-12 versus >12 month progression free interval (defined by the time following completion of first line platinum based chemotherapy)
2. Surgery versus no surgery at relapse prior to chemotherapy
3. Prior bevacizumab therapy
4. BRCA status (germline and/or somatic)

Statistical methods / analysis
The primary endpoint is progression-free survival (PFS). For the primary analysis, assuming 48 months recruitment and 12 months additional follow-up, an estimated 247 events are required in 286 randomised patients to detect HR=0.70 with 80% power and two-sided 5% significance level. In total, 330 patients will be randomised (1:1) to account for potential dropout and data maturity, registrations will continue until this target is reached. The sample size for the ANZ patients will be 110 randomisations. Registrations will continue until this target is reached.

The primary analysis of PFS will be performed using a stratified log-rank test, along with Kaplan-Meier curves. This will be measured from the date of randomisation to the date of objective disease progression (investigator assessed using RECIST v1.1) or date of death from any cause (in the absence of progression). Patients without an event would be censored at the date they were last seen in clinic (for those who were alive and had not progressed known to be alive).

Multivariable Cox proportional hazards regression will also be used to estimate the effect size and to adjust for the randomisation stratification factors.

If the non-proportional hazards assumption is clearly violated, with a test for non-proportionality of p=0.01, we will use an analysis of restricted mean survival times as measures of treatment effect.
