Platino-resistance in Ovarian Cancer

NA · Institut Claudius Regaud · NCT03954171

This study is trying to find out why some people with ovarian cancer don’t respond to standard platinum chemotherapy, by collecting information and samples from patients receiving this treatment.

What this trial studies

This prospective study aims to identify factors contributing to resistance against platinum-based chemotherapy in patients diagnosed with epithelial ovarian cancer at any stage. Participants will receive standard platinum-based chemotherapy while clinical, biological, epidemiological, and therapeutic data will be collected over a five-year period. Biological samples, including blood, tumor biopsies, and ascites, will be collected concurrently with standard care procedures, ensuring no additional invasive procedures are required. The study will help build a comprehensive database to better understand treatment resistance.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with newly diagnosed epithelial ovarian cancer who are eligible for platinum-based chemotherapy.

Not a fit: Patients with non-epithelial ovarian tumors, recurrent disease, or those who have already undergone curative treatment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with platinum-resistant ovarian cancer.

How similar studies have performed: While studies on chemotherapy resistance exist, this specific approach focusing on platinum resistance in ovarian cancer is novel and may provide new insights.
