Abstract
Background: The reported benefit of poly (ADP-ribose) polymerase inhibitor (PARPi) maintenance in patients with newly diagnosed and platinum (Pt)-sensitive recurrent ovarian cancer (OC) included in randomized clinical trials needs to be corroborated in a less selected population.
Objective: The aim is to increase the evidence on niraparib in a real-world setting.
Methods: This is a retrospective observational study including women with platinum-sensitive relapsed high-grade serous OC who started niraparib maintenance between August 2019 (marketing data, Spain) and May 2022. Patients received ≥ 2 previous lines of therapy with complete or partial response to prior chemotherapy. Patient characteristics, niraparib dose, adequacy of dose individualization, effectiveness (progression-free survival [PFS] and overall survival), safety, and economic savings with an individualized starting dose (ISD) strategy were assessed.
Results: The study included 217 patients with a median of 8.9 months of niraparib duration: breast cancer gene (BRCA) wild-type OC, 70%; two prior treatment lines, 49%; Research on Adverse Drug Events and Reports (RADAR) criteria, 82% (receiving mainly 200 mg of niraparib, 79%). Median PFS was 10.8 months (95% confidence interval [CI], 8.4-14.8) without statistically significant differences based on starting dose strategy, contrary to what was observed on the basis of prior lines, response to prior chemotherapy, BRCA mutational status, and International Federation of Gynecology and Obstetrics (FIGO) stage at diagnosis. The last three variables also showed a statistically significant predictive prognostic value for effectiveness. Dose interruptions due to toxicity were required in 7% of patients, and dose adjustments in 56% were mainly due to hematologic toxicities. The actual dose of niraparib reveals economic savings versus the theoretical cost.
Conclusion: This large real-world analysis corroborates the tolerability and activity of niraparib maintenance for platinum-sensitive recurrent OC and economic savings.
