Plain-language summary
PARP inhibitors are most effective in homologous recombinant (HR) deficient tumors. There are clear indications that besides BRCA1 or BRCA2 mutated EOC, there is an additional group of EOC having deficiencies in HR (i.e. BRCAness) that might benefit from treatment with PARP inhibitors. Assessment of HR in high grade EOC might therefore serve as a better predictive biomarker and allow the identification of a larger group of patients that could benefit most from platinum based chemotherapy and maintenance treatment with a PARP inhibitor. We recently developed a robust ex vivo functional assay (RAD51 assay;) to test HR in viable tumor tissue. In the proposed study, we will evaluate whether the RAD51 assay predicts sensitivity to therapy with olaparib, in patients with recurrent EOC. With the RAD51 assay we aim to identify a larger number of patients who will benefit from treatment with the PARP inhibitor olaparib than patients with a germline or somatic BRCA mutation only. Furthermore, we aim to identify molecular markers (including genomic markers) that are associated with the outcome of the RAD51 assay. Finally, we will explore whether these molecular markers can be measured in liquid biopsies by analysing ctDNA.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
