This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study of niraparib as maintenance in platinum sensitive ovarian cancer patients who have either gBRCAmut or a tumor with high-grade serous histology and who have responded to their most recent chemotherapy containing a platinum agent. Niraparib is an orally active PARP inhibitor. Niraparib or placebo (in a 2:1 ratio) will be administered once daily continuously during a 28-day cycle. Health-related quality of life will be measured by the Functional Assessment of Cancer Therapy - Ovarian Symptom Index (FOSI), European Quality of Life scale, 5-Dimensions (EQ-5D), and a neuropathy questionnaire. Safety and tolerability will be assessed by clinical review of adverse events (AEs), physical examinations, electrocardiograms (ECGs), and safety laboratory values.

The primary objective of this study is to evaluate efficacy of niraparib as maintenance therapy in patients who have platinum sensitive ovarian cancer as assessed by the prolongation of progression free survival (PFS).

Progression-Free Survival (PFS) in Cohort With No Germline BRCA Mutation

PFS was defined as the time between randomization and disease progression or death from any cause. Computed tomography or magnetic resonance imaging to assess disease progression was performed at baseline, every 8 weeks through cycle 14, and then every 12 weeks until treatment discontinuation. The objective assessment of disease progression was determined by means of central radiologic and clinical review, according to Response Evaluation Criteria in Solid Tumors (RECIST),version 1.1, which was performed in a blinded fashion.PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study.

Change From Baseline in Functional Assessment of Cancer Therapy-Ovarian Symptom Index in Cohort With Germline BRCA at Cycle 2

Functional Assessment of Cancer Therapy-Ovarian Symptom Index is a validated, 8-item measure of symptom response to treatment for ovarian cancer. Participants respond to their symptom experience over the past 7 days using a 5-point Likert scale score from "not at all" (0) to "very much" (4). The total score was calculated by multiplying the sum of all items scored by 8 and dividing the result by the number of responses. The total symptom index was calculated as the total of the 8 scores, ranging from 0 ("severely symptomatic") to 32 ("asymptomatic"). A positive change from Baseline indicates improvement. Baseline was latest non-missing pre-dose assessment on or before randomization date. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Change From Baseline in European Quality of Life Scale, 5-Dimensions (EQ-5D-5L) in Cohort With Germline BRCA at Cycle 2

EQ-5D-5L is a well-validated, general preference-based, health-related Quality of Life (QoL) instrument. The EQ-5D-5L encompasses 5 domains, asking participants to rate their perceived health state today on the following dimensions: Mobility, Self-Care, Usual Activities, Pain/Discomfort, and Anxiety/Depression. Each domain has 5 possible levels: "no problems" (Level 1), "slight problems" (Level 2), "moderate problems" (Level 3), "severe problems" (Level 4), and "extreme problems" (Level 5). Responses for 5 dimensions together formed a 5-figure description of health state (e.g.11111 indicates no problems in all 5 dimensions). Baseline was latest non-missing pre-dose assessment on or before randomization date. Change from Baseline was calculated by subtracting the Baseline value from the post-dose visit value.

Number of Participants With Response to Neuropathy Questionnaire in Cohort With Germline BRCA at Baseline

A Neuropathy Questionnaire measures the participant's symptom experience over the past 7 days using a 5-point Likert scale of "not at all" (0) to "very much" (4). There are 2 items that ask if the participant's feet (item 1) or hands (item 2) feel numb or have prickling/tingling feelings. The Neuropathy Questionnaire was used to determine the chemotherapy-induced peripheral neuropathy (CIPN) status of each participant as well as provide an anchor for interpreting the impact of CIPN on participant's QoL. Two thresholds were used. For the first, a participant was determined to have CIPN if a score greater than 0 ("not at all") was recorded for either item. For the second, CIPN was assigned if a participant recorded a score greater than 1 ("a little bit"). Baseline was latest non-missing pre-dose assessment on or before randomization date.

Number of Participants With Response to Neuropathy Questionnaire in Cohort With Germline BRCA at Cycle 4

A Neuropathy Questionnaire measures the participant's symptom experience over the past 7 days using a 5-point Likert scale of "not at all" (0) to "very much" (4). There are 2 items that ask if the participant's feet (item 1) or hands (item 2) feel numb or have prickling/tingling feelings. The Neuropathy Questionnaire was used to determine the chemotherapy-induced peripheral neuropathy (CIPN) status of each participant as well as provide an anchor for interpreting the impact of CIPN on participant's QoL. Two thresholds were used. For the first, a participant was determined to have CIPN if a score greater than 0 ("not at all") was recorded for either item. For the second, CIPN was assigned if a participant recorded a score greater than 1 ("a little bit").

Number of Participants With Non-serious Adverse Events (AEs) and Serious AEs (SAEs)

An AE is any untoward medical occurrence that occurs in a participants or clinical investigation participant administered a pharmaceutical product, and which does not necessarily have to have a causal relationship with this treatment. A SAE is defined as any untoward medical occurrence that at any dose which results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, is an important medical event(s) as per medical and scientific judgment. Adverse events which were not serious adverse events were considered as non serious adverse events. Data presented for this outcome measure is based on the data cut-off date of 31-March-2021, which aligns with the time of the study unblinding.
