Design and Validation of Plasma Proteins and Cytokine Panels to Identify Markers Associated With Response to Niraparib as Maintenance Treatment After First-line Platinum-based Regimen in Patients With Advanced Ovarian Cancer

PARPi inhibitors have been incorporated into managing first-line advanced ovarian cancer with different approvals depending on homologous recombination (HR) status. Niraparib has received approval independent from HR status. Although the benefit is more remarkable in HR-deficient patients, there is no biomarker to predict sustained response to niraparib at the start of treatment helping the clinician to make decisions among the different treatment options.
