Clinical Trial Summary

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.

Outcome

Type Measure Description Time frame Safety issue
Other Biomarkers associated with the response to pamiparib combined with surufatinib To identify the biomarkers, including but not limited to genomic, homologous recombination deficiency (HRD), that predict the efficacy of this study treatment. from the first drug administration up to two years
Primary Maximum tolerated dose (MTD) (Phase Ib) MTD is defined as the highest dose level at which no more than 1 out of 6 subjects experiences a dose limiting toxicity (DLT) during the first cycles. DLT is defined as: grade 3 febrile neutropenia, grade 4 hematologic toxicities, and = grade 3 non-hematologic toxicities that occurred within the first cycle of treatment with pamiparib and surufatinib. first 21 days of treatment
Primary Recommended Phase 2 dose (RP2D) (Phase Ib) Determine the RP2D of the pamiparib and surufatinib combination first 21 days of treatment
Primary Response Rate (ORR) (Phase II) ORR is the proportion of patients with best response of complete response (CR) and partial response (PR) according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. from the first drug administration up to two years
Secondary Progression-free Survival (PFS) Time from the date of first study treatment administration to the date of first documented tumor progression or death due to any cause, whichever occurs first. from the first drug administration up to two years
Secondary Disease Control Rate (DCR) Proportion of patients whose best overall response is either CR, PR, or SD. from the first drug administration up to two years
Secondary Duration of response (DOR) Time from first documented response (CR or PR) until documented disease progression or death, whichever occurs first. from the first drug administration up to two years
Secondary Overall survival (OS) Time from the date of first study treatment administration to the date of death due to any cause. from the first drug administration up to 2 years
Secondary Safety and tolerability Incidence, nature, and severity of adverse events graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v5.0. up to 90 days after last study treatment administration
