3 cycles carboplatin + paclitaxel maintenance therapy with niraparib (starting dose 200 mg QD or 300 mg QD); maintenance continues until disease progression and/or death, unacceptable adverse event/s, patient and/or investigator decision, other protocol stopping criteria.

6 cycles carboplatin + paclitaxel and maintenance therapy with niraparib (starting dose 200 mg QD or 300 mg QD); maintenance continues until disease progression and/or death, unacceptable adverse event/s, patient and/or investigator decision, other protocol stopping criteria.

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.

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.

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.

Patients are asked to answer the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 30 (QLQ-C30). Responses of questions 1-28 are based on a 4-point scale (1=not at all; 4=Very much), with a higher score indicating a high degree of symptomatology and must therefore be assessed negatively. Responses of questions 29 and 30 are based on a 7-point scale (1=Very poor; 7=Excellent), with a higher score indicating a better global health status.

Patients are asked to answer the EORTC QoL Questionnaire-Ovarian Cancer (QLQ-OV28). Responses are based on a 4-point scale (1=Not at all; 4=Very much), with a lower score indicating better symptoms.

Patients are asked to answer the short version of the SF-36 Health Survey (SF-12). The questionnaire contains a total of 12 questions with different response options. For questions 1, 8 and 12 there are 5 (1=excellent, 5=bad), for question 2-3 there are 3 (1=yes, very restricted, 3=no, not restricted at all) and for questions 9-11 there are 6 response options (1= always, 6 = never). Questions 4-7 can be answered with "Yes" or "No".

The safety objective is to characterize the safety and tolerability of 3 vs. 6 cycles of chemotherapy followed by maintenance therapy with niraparib in advanced HRDpositive high-grade ovarian cancer patients with no residual tumor mass following primary tumor debulking. The following safety parameters will be analyzed: adverse events and serious adverse events graded per NCI CTCAE, Version 5.0 criteria with time to onset/recovery, causality and outcome; changes in laboratory values, vital signs since baseline, treatment discontinuations and reason for discontinuation, death and cause of death etc. concomitant medications will be collected with time and reasons of use. These are routine safety parameters collected and analyzed in Phase II /III oncology trials.

The objective is to show that less cycles of chemotherapy are as efficient and at the same time less toxic. Additional cycles of chemotherapy significantly increase toxicity and therefore lead to an increase of costs regarding, e.g. in-patient treatment, concomitant medications to treat (S)AEs.
