Pamiparib Plus Surufatinib in Patients With Platinum-resistant Ovarian Cancer

A number of studies suggest that the combination of PARP inhibitors and antiangiogenic agents produce synergistic activities. Pamiparib is a small molecule inhibitor selectivity for both PARP1 and PARP2. Surufatinib is a novel small-molecule inhibitor that simultaneously targets tumor angiogenesis (via Vascular Endothelial Growth Factor Receptor \[VEGFR\]1, VEGFR 2, VEGFR3 and Fibroblast Growth Factor Receptor 1 \[FGFR1\]) and immune evasion (via Colony Stimulating Factor 1 Receptor \[CSF1R\]). In this trial, we aimed to evaluate the efficacy, safety and tolerability of pamiparib in combination with surufatinib in patients with platinum-resistant ovarian cancer who received prior PARP inhibitors.
