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

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

Observational Hospices Civils de Lyon · NCT06572735

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.

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.

Who should consider this trial

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.

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.

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 performed: 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.
