Multi-Centre Observational Study of Maintenance Niraparib in Treatment of Ovarian CanceR

This is a multi-centre, observational (non-interventional) study, designed to follow patients with advanced ovarian fallopian tube and primary peritoneal cancer, who are receiving Niraparib as maintenance treatment, according to the Niraparib access criteria (via TESARO patient access programme, EMA licence and NHS pending NICE assessment due 2018) including assessment of tolerability to Niraparib therapy. These pathways will include patients who have been registered and not prescribed drug. In these cases, the reason for patients not receiving Niraparib will be recorded. Up to 16 centres will be involved in the study. Centres will be selected based on interest in or experience of prescribing Niraparib and geographical location in order to give a representative picture of the management of Niraparib in the UK.

Cohort 1: Retrospective Cohort

This cohort will include:

• Patients who have previously commenced maintenance Niraparib prior to the MONITOR study opening at the site and are still receiving Niraparib but in whom quality of life data are not available.

• Patients who have previously commenced Niraparib prior to the MONITOR Study opening at the site but are now deceased but will be eligible for retrospective data collection without the need for informed consent.

• Patients who have previously commenced maintenance Niraparib prior to the MONITOR study opening at the site but have discontinued treatment.

• Data in respect of AEs, SAEs, ADRs and AESIs will be recorded in Case Report Forms and be identified via the patient's medical records. There is no requirement to complete trial specific SAE reporting forms in this cohort.

Cohort 2: Prospective Cohort

This cohort will include:

• Patients who have previously commenced maintenance Niraparib prior to the MONITOR study opening at the site and are still receiving Niraparib and in whom quality of life data is available.

• Patients who are due to commence maintenance Niraparib treatment.

The collection of QoL data, using EQ-5D-5L and EORTC QoL-OV28, FACT-O questionnaires will be mandatory. For patients continuing on Niraparib, data will be collected retrospectively to the point they sign the consent form, and prospectively. Going forward QoL data will not be collected for these patients unless available as part of routine clinical care and baseline QoL is available.

The collection of data relating to adverse events will be mandatory. The scope of adverse events to be recorded includes AEs, SAEs, ADRs and AESIs - see section 5.3.1 for definitions of these events. Details in respect of AEs and SAEs, ADRs and AESIs will be recorded during routine clinic visits or via standard of care contact with the patient.

No additional visits will be required, no study medication will be administrated, and no additional procedures will be performed outside the local routine practice as part of the trial. Patients will be managed and followed up according to routine practice. Only data available in the patient's medical record will be collected. Patients consented to cohort 2 will be asked to complete validated QoL tools; EQ-5D-5L, FACT-O and EORTC QOL-OV28. Approximately 350 patients will be enrolled with an estimated 100 in the retrospective cohort and 250 in the prospective cohort.
