FLAME: A Study to Characterize the Outcomes of Olaparib Maintenance Monotherapy in Newly Diagnosed BRCAwt Ovarian Cancer
Study Details
Study Description
Brief Summary
This study will collect the data from existing patient medical records at US cancer centers. The study will include patients with BRCAwt ovarian cancer who have been prescribed first line (1L) olaparib maintenance treatment.

Detailed Description
This is a United States (US) based multicenter, retrospective, observational cohort study with data abstracted from patient medical records.
In this observational study, it is planned to include approximately 150 US female patients with newly diagnosed advanced ovarian cancer (AOC) who were tumor biomarker tested between first diagnosis with AOC and first prescription of 1L olaparib maintenance monotherapy as tumor breast cancer gene wild type (BRCAwt) with a known homologous recombination deficiency (HRD) status.
This retrospective cohort study will include patients with first olaparib prescription between Jan 2017 and Dec 2021. All data collection will be retrospective. Data will be collected from the date of first olaparib prescription (index date) with a follow-up period of at least 18 months post index date.

Outcome Measures
Primary Outcome Measures
- Clinical and Demographics characteristics [At Index date - first olaparib prescription (Jan 2017 to Dec 2021)]
Clinical and Demographic characteristics including disease/FIGO stage, histology and tumor grade at initial Ovarian Cancer diagnosis, cancer antigen 125 (CA-125) level, Eastern Cooperative Oncology Group (ECOG) or other performance status, number and type of chemotherapy cycles, cytoreductive/debulking surgery type and outcomes, and selected comorbidities at index date will be described. Summary statistics will be used to describe the Demographics and clinical characteristics. The outcome will be measured for HRD+ patients.
Secondary Outcome Measures
- Real-world time to first subsequent treatment or death (rwTFST) [Jan 2017 to Jun 2023]
rwTFST is defined as the time from the index date to the earliest of the date of death or commencement of first subsequent anticancer treatment. The outcome will be measured for HRD+ patients.
- Real-world time to treatment discontinuation or death (rwTTD) [Jan 2017 to Jun 2023]
rwTTD is defined as the time from the index date to the earliest of the date of death or discontinuation of olaparib. The outcome will be measured for HRD+ patients.
- Number of patients with clinical event of interest (CEI) [Jan 2017 to Jun 2023]
To summarize the real-world safety and tolerability profile based on pre-specified CEIs of 1L olaparib maintenance monotherapy in BRCAwt newly diagnosed AOC patients regardless of HRD status.
