What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression free survival(PFS) by Blinded Independent Review Committee (BIRC) in relapsed ovarian cancer patients	Defined as progression free survival per RECIST 1.1 criteria	up to 2 years
Progression free survival(PFS) by BIRC in relapsed ovarian cancer patients with Breast cancer susceptibility gene(BRCA) mutant	Defined as progression free survival per RECIST 1.1 criteria	up to 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression free survival(PFS) in relapsed ovarian cancer patients	PFS is Progression-Free-Survival per RECIST 1.1 criteria	up to 2 years
Time to progression(TTP) by Gynecological Cancer Intergroup(GCIG) CA 125 criteria	TTP is Time to Progression	up to 2 years
Chemotherapy free interval (CFI) CFI	CFI is the time from last platinum dose until initiation of next anticancer therapy (excluding maintenance therapy if used following the penultimate regimen)	up to 2 years
overall survival(OS)	OS is the time interval from the start of treatment to death due to any reason or lost of follow-up	up to 3 years
Objective Response Rate	Objective Response Rate complete or partial response per RECIST 1.1 criteria	At baseline,at the time point of every 12 weeks, up to 2 years
Adverse Events(AEs) and Serious Adverse Events (SAEs)	assess the safety and tolerability of Fluzoparib maintenance monotherapy in platinum sensitive relapsed ovarian cancer patients by record the number of Participants with of AEs and SAEs, and the proportion of patients with AEs and SAEs, etc.	from the first drug administration to within 30 days for the last treatment dose
