Camrelizumab Combined With Apatinib in the Treatment of Epithelial Ovarian Cancer

A Single-arm, Prospective Clinical Study of Camrelizumab Combined With Apatinib Mesylate in the Treatment of Relapsed Platinum-resistant Epithelial Ovarian Cancer

The aim of this study is to explore the effectiveness and safety of camrelizumab combined with apatinib mesylate in the treatment of relapsed platinum-resistant epithelial ovarian cancer

The anti-PD-1 drug camrelizumab combined with apatinib mesylate was used to treat relapsed platinum-resistant epithelial ovarian cancer, and the effectiveness and safety of the treatment plan was evaluated by objective remission rate, progression-free survival, and major safety indicators , so as to provide patients a more beneficial treatment plan.
