Description of intervention(s) / exposure
A phase 2 study, single group assignment.
Participants have been categorised into two cohorts upon registration into the study. Each cohort is defined as the following:
- Cohort 1: Participants registered to the study who have had most recent treatment with substrate-PARPi. Patients n=20
- Cohort 2: Participants registered to the study who have had most recent treatment with chemotherapy. Patients n=20
Experimental drug is Pamiparib (BGB-290)
60 mg of Pamiparib (3 capsules of 20mg) will be administered orally twice a day, once in the morning and once in the evening continuously in 28 day cycles.
Patients will remain on treatment until progressive disease, unacceptable toxicity, patient discontinuation/withdrawal or at the discretion of the investigator. Patients who discontinue treatment due to progressive disease will be followed for survival only and patients who discontinue treatment for other reasons will be followed for progression and survival.
Patients can be on treatment continuously until 3 years after the last patient has commenced treatment. This equates to an average of 3 to 5 years for the purpose of this study
A patient diary will be used to monitor adherence to the study drug Pamiparib.

Summary
Brief summary
Ovarian cancer is the deadliest gynaecologic cancer in Western women.
The purpose of this study is to test the effect of a new drug called Pamiparib in patients with high grade serous ovarian cancer with BRCA1/2 mutations who have progressed on PARPi or chemotherapy.
Who is it for?
You may be eligible for this study if you are aged 18 or over and have a diagnosis of high grade serous ovarian cancer or carcinosarcoma of the ovary (including primary peritoneal cancers and Fallopian tube cancers).
Study details
All participants in this study will take three capsules (60mg) of the medication Pamiparib every morning and evening continuously and will have hospital visits for assessments every 28 days for the first 8 months, then every 3 months thereafter, 28 days is defined as 1 treatment cycle. Participants will be asked to provide blood samples, biopsy tissue for analysis and allow access to medical records. Treatment with pamiparib will continue until disease progression, unacceptable toxicity for the participant, or participant discontinuation/withdrawal from the study.
It is hoped this research will demonstrate the sensitivity of high-grade serous ovarian cancer and carcinosarcoma of the ovary to this new medication, expanding treatment options for patients with these cancer types.
