A Study for Post-Marketing Surveillance of Niraparib in the Treatment of Adult Participants for Approved Indications in South Korea

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to estimate the cumulative incidence of all adverse events (AEs), including serious adverse events (SAEs), adverse event of special interest (AESI), among participants who have been administered niraparib as per the approved indications.

Detailed Description
-----------------
This is a long-term prospective, observational post-marketing surveillance study of niraparib in participants with ovarian cancer (including fallopian tube, or primary peritoneal cancer) who are in complete or partial response to first-line platinum-based chemotherapy or who had complete or partial response to 2 or more lines of platinum-based chemotherapy or who have been treated with 3 or more prior chemotherapy regimens with either: BRCA mutation irrespective of platinum sensitivity; or platinum-sensitive HRD positive. The study will assess the safety and effectiveness of niraparib for its approved indication with real-world setting in South Korea. The study will enroll approximately 600 participants. The data will be collected prospectively at the study sites will be recorded into electronic case report forms (e-CRFs). All the participants will be assigned to a single observational cohort: • Participants With Ovarian Cancer The multi-center study will be conducted in South Korea. Data collection will be based on routinely scheduled and emergency visits during a 24-month surveillance period or until end of the study whichever occurs first after drug administration. The overall duration of the study will be approximately 6 years.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Participants with Ovarian Cancer<br>Participants diagnosed with ovarian cancer (including fallopian tube or primary peritoneal cancer) who have been prescribed with niraparib for the first time in a real-world setting, and who are in a complete or partial response to first-line platinum-based chemotherapy or who had complete or partial response to 2 or more line of platinum-based chemotherapy or who have been treated with 3 or more prior chemotherapy regimens with either breast cancer susceptibility gene (BRCA) mutation (irrespective of platinum sensitivity) or platinum-sensitive homologous recombination deficiency (HRD) positive will be observed prospectively over 24-month period, or until treatment discontinuation, or until end of study, which occurs first. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants with AEs, SAEs, and AESIs |  | Baseline up to 24 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time-to-Treatment Discontinuation (TTD) | TTD is defined as the time interval from the date of initiation of treatment until discontinuation of treatment, or death due to any cause, whichever occurs first. Participants who have not discontinued treatment, or died, will be censored at the last known time that the participant was on treatment. | From the date of first dose administration until discontinuation or death due to any cause whichever occurs first (up to 24 months) | 
| Progression Free Survival (PFS) | PFS is defined as the time interval from the date of initiation of treatment until objectively documented disease progression, or death due to any cause, whichever occurs first. Participants who do not have disease progression, or have not died, will be censored at the last known time that the participant was progression-free. Progressive disease (PD) is defined as at least a 20 percent (%) increase in the sum of the longest diameter (LD) of lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. The determination of disease progression will be at the Investigators discretion per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria. | From the date of first dose administration until disease progression or death due to any cause whichever occurs first (up to 24 months) |
