The degree of malignancy of small cell lung cancer is extremely high. About 60% to 70% of patients are diagnosed as extensive. The median survival time of the disease is only 9 to 10 months, and the 2-year survival rate is less than 10%. Fluzoparib is an oral potent, selective poly-ADP ribose polymerase-1 (PARP-1) and PARP-2 inhibitor. Apatinib is an oral selective vascular endothelial growth factor receptor (VEGFR) inhibitor.This open-label, dose finding phase Ib trial studies the tolerability and the best dose of fluzoparib in combination with apatinib as second-line treatment of patients with extensive stage small cell lung cancer. The safety and efficacy of fluzoparib in combination with apatinib will be explored.
This open-label, dose finding phase Ib trial studies the tolerability and the best dose of fluzoparib in combination with apatinib and to see how well these two drugs work together as second-line treatment of patients with extensive stage small cell lung cancer. The safety and efficacy of fluzoparib in combination with apatinib will be explored. Both dose escalation and dose expansion parts are included in this study.
