Overview
Brief Summary
Ovarian cancer is the leading cause of death from gynecologic tumors in the western world. Most patients have relapses, and responses to subsequent therapies are generally short-lived. Currently, the population that can benefit from PARPi is mainly focusing on BRCAm, then homologous-recombination deficiency patients. Limited data revealed the ORR was only 3-4% in homologous recombination proficiency patients with PARPi therapy. New treatments are urgently needed to improve patient outcomes.
To explore the efficacy and safety of Fuzuloparib in combination with Arsenic trioxide therapy in platinum-resistance relapsed Ovarian cancer patients.
Detailed Description
Ovarian cancer is the leading cause of death from gynecologic tumors in the western world. Most patients have relapses, and responses to subsequent therapies are generally short-lived. Currently, the population that can benefit from PARPi is mainly focusing on BRCAm, then homologous-recombination deficiency patients. Limited data revealed the ORR was only 3-4% in homologous recombination proficiency patients with PARPi therapy. New treatments are urgently needed to improve patient outcomes. The investigators' studies have shown that combination therapy with Fuzuloparib and Arsenic trioxide demonstrated a synergistic anti-tumor effect in BRCAness/HR-proficiency ovarian cancer cells: Firstly, CCK8 and clone formation assays showed that the combination of Fuzuloparib and Arsenic trioxide produced notable tumor cell growth inhibition than either single agent in SKOV3 and CAOV3 cells. Further, the combination therapy resulted in significantly increased level of γ-H2AX and decreased level of RAD51 by IF.The investigators also found that combination therapy could remarkably induced cell apoptosis, which is associated with induction of cleave-PARP and reduction of p-AKT, when compared with either single drug. (Data not published) Therefore, the investigators hypothesis is that for those platinum-resistance relapsed patients who have received at least twice platinum-based chemotherapy, patients with combinate therapy will get 25% of ORR. And platinum-resistance in combination with Arsenic trioxide therapy is well tolerated.

Outcomes
Primary Outcomes
ORR
Time Frame: From date of randomization until PD or death from any cause, assessed up to 36 months.
ORR is defined as the rate of CR or PR, as determined by IRC using RECIST v1.1 criteria among patients with at least one target lesion. Activity was also described in women with nontarget lesions only and in women without any tumor lesion but with elevated CA-125 levels before starting treatment.
Secondary Outcomes
- OS(From date of randomization until the date of death from any cause, or date of last follow-up for patients still alive, assessed up to 36 months])
- quality of life assessment(It will be assessed at baseline and before the administration of drugs at each first day of every two chemotherapy cycles, up to 6 cycles,each cycle is 28days.)
- PFS(From date of randomization until the date of first documented progression or death from any cause, whichever occurred first, or last follow-up for patients alive without progression, assessed up to approximately 36 months)
- the incidence and severity of adverse reactions(A summary of adverse events of each cycle,from date of administration of drugs until 30 days after the last chemotherapy or progression,whichever came first,assessed up to 36 months)
