Relapsed Ovarian Cancer

ACTOv will compare standard 3-weekly carboplatin (AUC5), to carboplatin delivered according to an AT regimen. The AT regimen will modify carboplatin dose according to changes in the clinical-standard serum biomarker CA125 as a proxy measure of total tumour burden and an individual patient's response to the most recent chemotherapy treatment. AT could prolong sensitivity to carboplatin and extend tumour control, while simultaneously reducing chemotherapy dose and drug-induced toxicity. Carboplatin is a low cost and low toxicity drug that has an enduring and central role in ovarian cancer treatment.

This study is a Phase II single-arm, open label, multicenter study to access the effects and tolerability of fluzoparib combined with apatinib for maintenance treatment in platinum-sensitive relapsed ovarian carcinoma .

This study aims to carry out a multi-center, randomized controlled study on patients with recurrent ovarian cancer after PARPi maintenance, to explore the clinicopathological and molecular characteristics of patients with recurrent ovarian cancer after PARPi maintenance, and to clarify whether patients with recurrent ovarian cancer after PARPi maintenance for more than 6 months are sensitive to platinum drugs, and the value of secondary tumor cell reduction in such treatment, In order to provide evidence-based medicine basis for the standardized treatment mode of recurrent ovarian cancer after PARPi maintenance treatment.

This study is a Phase II randomized, open label, controlled, multicenter study to access the effects and tolerability of fluzoparib combined with apatinib versus fluzoparib monotherapy for maintenance treatment in platinum-sensitive relapsed ovarian carcinoma (including patients previous treated with a PARP inhibitor).
