Administering niraparib to patients with recurrent ovarian cancer after a complete response (CR) or partial response (PR) to platinum-based chemotherapy may allow patients to continuously maintain their quality of life (QOL) during treatment, according to a study presented at the European Society for Medical Oncology (ESMO) 2017 Congress.
The ENGOT-OV16/NOVA trial (ClinicalTrials.gov Identifier: NCT01847274) previously demonstrated that niraparib significantly prolonged progression-free survival (PFS) in patients with recurrent ovarian cancer following CR or PR.
Study authors analyzed patient-reported outcomes (PROs) associated with QOL, and the Functional Assessment of Cancer Therapy-Ovarian Symptoms Index (FOSI) and European Quality of Life Scale 5-Dimensions (EQ-5D-5L) were used to evaluate individual patient-reported symptoms in the niraparib and placebo groups.
A mixed-effect growth-curve adjusted for 3 stratification factors and baseline demographics was formed to reflect the relationship between the PRO scores and treatment for each measure. Health status and PRO associations were determined by a cross-sectional analysis of adjusted EQ-5D-5L health utility index (HUI) scores.
Results of the study showed no significant difference in mean PRO scores between the niraparib and placebo arms. The adjusted HUI scores were comparable at baseline in both study arms, but average adjusted HUI scores prior to progression trended higher for the niraparib arm (0.812 vs 0.803 in gBRCAmut cohort; 0.845 vs 0.828 in non-gBRCAmut cohort).
Patients’ overall health utility was not negatively impacted by hematologic toxicities.
