Summary

Multicenter, randomized, open label study including patients with advanced HRDpositive high-grade ovarian cancer, fallopian tube cancer, primary peritoneal cancer and clear cell carcinoma of the ovary with no residual tumor mass following primary tumor debulking to determine recurrence free survival in patients treated with 3 cycles carboplatin + paclitaxel and maintenance therapy with niraparib vs. 6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib.

Detailed description

This is a multicenter, randomized, open label study including patients with advanced (FIGO stage IIIA, IIIB, IIIC, or IV of the 2014 FIGO classification) HRDpositive high-grade ovarian cancer, fallopian tube cancer, primary peritoneal cancer and clear cell carcinoma of the ovary with no residual tumor mass following primary tumor debulking. The main scope of the trial is to determine recurrence free survival in patients treated with 3 cycles carboplatin + paclitaxel and maintenance therapy with niraparib vs. 6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib. Patients will be randomized 1:1 to receive either 3 cycles carboplatin + paclitaxel maintenance therapy with niraparib (Arm A) or 6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib (Arm B). Randomization will be performed according to the results of the NGS analysis and stratified either to BRCAm independent of LOH or LOHhigh/ BRCAwt, FIGO stage III vs. IV, and countries. In both of the arms, tumor assessments (CT or MRI) will be performed 9-12 weeks after the start of therapy (after 3rd cycle of chemotherapy), after another 9-12 weeks (during maintenance therapy in Arm A and after the 6th cycle of chemotherapy in Arm B) and every 6 months thereafter. The tumor marker CA-125 will be assessed every 12 weeks in both arms. During chemotherapy treatment, clinical visits (blood cell counts, detection of toxicity) occur at least every 3 weeks (depending on the chemotherapy regimen). Serum pregnancy tests for WOCBP occur at least every 4 weeks. During maintenance therapy with niraparib, clinical visits (blood cell counts, detection of toxicity) occur every 4 weeks for the first 11 months and every 12 weeks thereafter. Serum pregnancy tests for WOCBP occur at least every 4 weeks. Complete physical examinations will take place every 12 weeks. Safety will be monitored continuously by careful monitoring of all adverse events (AEs) and serious adverse events (SAEs). About 60 sites in 6 European countries will participate in this study to recruit 640 patients in 36 months.

Conditions

Interventions

Type	Name	Description
DRUG	3 cycles chemotherapy instead of 6 cycles chemotherapy	We hypothesise that recurrence free survival in patients receiving 3 cycles of chemotherapy followed by maintenance with niraparib is not inferior to 6 cycles of chemotherapy followed by niraparib in advanced HRDpositive high-grade ovarian cancer patients with no residual tumor mass following primary tumor debulking.
DRUG	6 cycles chemotherapy	Standard chemotherapy as comparator
