- Brief Summary
Ovarian cancer is the seventh most common cancer in women worldwide and is the leading cause of gynecologic cancer deaths in high-income countries.
Standard treatment for newly diagnosed advanced ovarian cancer consist of cytoreductive surgery and platinum-based chemotherapy with or without concurrent and maintenance bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor.
A majority of women with epithelial ovarian cancer respond well to first-line platinum-based chemotherapy. There is however a high rate of relapse/recurrence (disease progression ranging from 10 to 26 months).
Poly ADP ribose polymerase inhibitors (PARPi), a new class of therapeutic molecules have recently revolutionized this paradigm, demonstrating progression-free survival (PFS) advantages in several trials.
The PARPi molecule Niraparib has obtained its market authorization after the NOVA trial as second maintenance treatment line, irrespectively of patients' BRCA-mutated gene or HR status.
Since, results of the Phase III trial PRIMA, have demonstrated that Niraparib can also provided a significant PFS increase as first line maintenance treatment, for adult patients with platinum-sensitive, relapsed, high grade serous epithelial ovarian cancer who are in response (complete response or partial response) to platinum-based chemotherapy, irrespectively of their BRCA-mutated gene or HR status.
However, despite its high therapeutic potential, Niraparib at standard dose (200 or 300mg/day) is known to lead to hematologic toxicity and/or nephrotoxicity. This was demonstrated during the NOVA trial (the dose of Niraparib having to be reduced in 80% of the patients to reduce toxicity).
A retrospective study of the NOVA trial indicates that 2 predictive factors leading to hematologic toxicity were a weight \<77kg and an initial platelet count \<175 G/L. However, it seems more complex as 50% of patients with an initial weight between 58 and 77kg have not reported thrombocytopenia. Same for platelet count. Creatinine clearance below 60ml/min and an hypoalbuminemia \<35 g/l have also been identified in another study as predictive factors to thrombocytopenia.
The inter-individual heterogeneity in terms of toxicity regarding Niraparib is high and still not well understood.
The aim of our study is therefore to better identify which clinical, biological and pharmacokinetic metrics can be considered as toxicity induction causes when Niraparib is used as maintenance treatment (200 or 300mg/day) for ovarian cancer patients.

Group Intervention Description Pharmacokinetics, Dosage of Niraparib Pharmacokinetics, Dosage of Niraparib Patients received 3 cycles of Niraparib (200 mg or 300 mg/day). Each cycle lasts 28 days. Serum niraparib assays will be performed for all patients over 3 courses immediately prior to treatment (Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1). Close-up kinetic measurements will also be taken at 1 Hour, 2 Hours, 4 Hours, 6 Hours and 24 Hours at Cycle 1 Day 15.
- Primary Outcome Measures
Name Time Method Identification of metrics (clinical, biological, pharmacokinetic) that are considered as toxicity induction causes (hematological toxicity or nephrotoxicity) Month 10; after all the blood sample collection is achieved for all included patients. Blood will be sampled at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and based on the obtained results, it will be seek if a link can be established between the clinical, biological and pharmacokinetic metrics and the observed toxicity.
- Secondary Outcome Measures
Name Time Method Relationship between the quality of life and the observed toxicity assessed by the "EORTC OVARIAN" questionnaire Month 10, after last patient enrolment. Analysis of quality of life by "QLQ OV28" questionnaire score collected at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and observed toxicity.
Relationship between the pharmacokinetic metrics and the PFS at 24 months. Month 34; after last patient inclusion (Month 10) + 24 months. Blood will be sampled at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and based on the obtained results, it will be determined if a link can be established between the pharmacokinetic metrics and the PFS at 24 months
Relationship between the quality of life and the observed toxicity assessed by the "Charlson Score" questionnaire Month 10, after last patient enrolment. Analysis of quality of life by "Charlson Score" questionnaire score collected at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and observed toxicity.
Relationship between the quality of life and the observed toxicity assessed by the "Assessment of polymedication" questionnaire Month 10, after last patient enrolment. Analysis of quality of life by "Assessment of polymedication" questionnaire score collected at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and observed toxicity.
Relationship between the quality of life and the observed toxicity assessed by the "Recording of food intake and monitoring of eating habits" questionnaire Month 10, after last patient enrolment. Analysis of quality of life by "Recording of food intake and monitoring of eating habits" questionnaire score collected at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and observed toxicity.
Determination of the average pharmacokinetic metrics observed in our study panel patients. Month 10; after all the blood sample collection is achieved for all included patients.. Blood will be sampled at Cycle 1 Day 1, Cycle 1 Day 15, Cycle 2 Day 1 and Cycle 3 Day 1 and based on the obtained results, the average metrics of pharmacokinetic parameters will be determined.
