About

The goal of this observational study is to learn about the treatment effectiveness of physician's choice of chemotherapy and the immune checkpoint inhibitor (ICI)-based therapy in patients with relapsed/refractory ovarian clear cell carcinoma (OCCC), and compare the treatment response with the phase II, single-arm clinical trial INOVA to investigate the efficacy of combinational therapy of sintilimab plus bevacizumab. The main questions it aims to answer are:

  • What is the efficacy of physician's choice of chemotherapy in relapsed/refractory OCCC patients in the real world?
  • Is ICI-based therapy more effective than physician's choice of chemotherapy in real-world for relapsed/refractory OCCC patients?
  • Dose the combinational regimens of sintilimab plus bevacizumab in Sintilimab Plus Bevacizumab in Recurrent/Persistent Ovarian Clear Cell Carcinoma (INOVA) trial more effective than physician's choice of chemotherapy?

Participants will be respectively retrieved and extracted de-identified, longitudinal electronic health records (EHR)-derived data.
