Relative dose intensity of PARP inhibitors in people over 70 with advanced ovarian cancer

Official title: Study on the Relative Dose Intensity of PARP Inhibitors in Real-life on a Population of Patients Over 70 Years With Advanced Ovarian Cancer

Run by Hospices Civils de Lyon · NCT06572735 · Data updated 2026-11-12

This project will see how often people age 70 and older with advanced ovarian cancer can stay on full PARP inhibitor doses and how blood-related side effects lead to dose changes in routine care.

Is this trial a fit for you?

Likely a good fit

People aged 70 or older with histologically or cytologically confirmed advanced (FIGO III or IV) ovarian cancer who are PARP-inhibitor–naive and about to start maintenance oral PARP therapy, able to take pills and attend follow-up, are ideal candidates.

Probably not a fit

Patients previously treated with PARP inhibitors, those unable to take oral tablets or attend required visits, or those with a very short expected survival are unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational study enrolling patients aged 70 or older with FIGO stage III–IV ovarian cancer who are starting maintenance PARP inhibitor therapy for the first time. Participants receive a baseline geriatric assessment (G-CODE), quality-of-life questionnaires, and regular blood tests to monitor hematologic toxicity such as anemia, thrombocytopenia, and neutropenia. Investigators will track dose delays, reductions, discontinuations, and calculate relative dose intensity in real-life practice. The aim is to identify geriatric factors linked to reduced tolerance so clinicians can better tailor monitoring and dosing for older patients.

Why it matters

Potential benefit: If successful, the results could help doctors personalize monitoring and dosing so more older patients stay on effective PARP inhibitor treatment with fewer severe blood-related side effects.

How similar studies have gone: PARP inhibitors are proven effective in advanced ovarian cancer generally, but prospective real-life data on dose intensity and tolerability specifically in patients aged 70 and older are limited.
