Comparing treatments for ovarian clear cell carcinoma patients

A Comparative Study of the Treatment of Real-world Patients With Clear Cell Carcinoma of the Ovary

Observational Tongji Hospital · NCT06279104

This study is testing whether chemotherapy chosen by doctors or a new immune therapy works better for patients with relapsed ovarian clear cell carcinoma.

What this trial studies

This observational study aims to evaluate the effectiveness of physician's choice of chemotherapy versus immune checkpoint inhibitor (ICI)-based therapy in patients with relapsed or refractory ovarian clear cell carcinoma (OCCC). It will compare real-world treatment responses to those observed in a previous phase II trial involving sintilimab and bevacizumab. The study seeks to answer key questions about the efficacy of these treatment options in a real-world setting, focusing on patient outcomes and survival rates.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 to 75 with a histological diagnosis of ovarian clear cell carcinoma who have undergone at least one line of platinum-containing chemotherapy.

Not a fit: Patients with non-ovarian clear cell carcinoma or those who do not meet the inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into more effective treatment options for patients with ovarian clear cell carcinoma.

How similar studies have performed: Previous studies have shown promise in using immune checkpoint inhibitors for ovarian cancer, but this specific comparative approach is novel.
