INOVA: Sintilimab Plus Bevacizumab in Recurrent/Persistent Ovarian Clear Cell Carcinoma
Study Details
Study Description
Brief Summary
Ovarian clear cell carcinoma (OCCC) is one of the rare subtypes of ovarian cancer, yet its prognosis is extremely poor. Previous studies indicate that both bevacizumab and PD-1 inhibitor have clinical benefits for OCCC patients. And the combination of bevacizumab and PD-1 inhibitor has shown preliminary safety and clinical activity. Therefore, this study aims to investigate the potential benefit of combination therapy for patients with OCCC.
