Inclusion and exclusion criteria

Inclusion Criteria

1. Provision of informed consent prior to any study specific procedures
2. Age 18 years or over
3. Patients with platinum sensitive relapsed high grade (serous or endometrioid) epithelial ovarian cancers (including primary peritoneal and/or fallopian tube cancer)
-Platinum sensitive disease is defined as disease progression ≥6 months after completion of their last dose of platinum based chemotherapy
4. Patients should have received at least 2 previous lines of platinum containing therapy prior to enrolment:
-For the last chemotherapy course immediately prior to enrolment on the study, patients must be, in the opinion of the investigator, in response (partial or complete radiological response according to RECIST 1.1 criteria) and no evidence of a rising CA-125, following completion of this chemotherapy course.
5. Have availability of 10 ml blood for germline BRCA testing and tumor sample for sBRCA and HRRm testing: paraffin-embedded archived tumor tissue block (preferred) or, if a block is not possible, it would be better to have qualified 15 5-μm unstained sections.
6. Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined below:
-Haemoglobin ≥ 10.0 g/dL with no blood transfusions in the past 28 days
-Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
-Platelet count ≥ 100 x 109/L
-Total bilirubin ≤ 1.5 x institutional upper limit of normal (ULN)
-Aspartate aminotransferase (AST) (Serum Glutamic Oxaloacetic Transaminase (SGOT)) / Alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) ≤ 2.5 x institutional upper limit of normal unless liver metastases are present in which case they must be ≤ 5x ULN
-Patients must have creatinine clearance estimated using the Cockcroft-Gault equation of ≥51 mL/min:
Estimated creatinine clearance =[(140-age [years]) x weight (kg)]/[serum creatinine (mg/dL) x 72] (x F)a
a: where F=0.85 for females and F=1 for males.
7. Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
8. Patients must have a life expectancy ≥ 16 weeks.
9. Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test within 28 days of study treatment and confirmed prior to treatment on day 1.
Postmenopausal is defined as:
-Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments
-Luteinizing hormone (LH) and Follicle stimulating hormone (FSH) levels in the post menopausal range for women under 50
-radiation-induced oophorectomy with last menses >1 year ago
-chemotherapy-induced menopause with >1 year interval since last menses
-surgical sterilisation (bilateral oophorectomy or hysterectomy)
10. Patients is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations.

Exclusion Criteria

1. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site)
2. Previous enrolment in the present study
3. Participation in another clinical study with an investigational product during the most recent chemotherapy course
4. Any previous treatment with PARP inhibitor, including olaparib
5. Other malignancy within the last 5 years except: adequately treated non-melanoma skin cancer, curatively treated in situ cancer of the cervix, ductal carcinoma in situ (DCIS), Stage 1, grade 1 endometrial carcinoma, or other solid tumours including lymphomas (without bone marrow involvement) curatively treated with no evidence of disease for ≥5 years. Patients with a history of localised triple negative breast cancer may be eligible, provided they completed their adjuvant chemotherapy more than three years prior to registration, and that the patient remains free of recurrent or metastatic disease
6. Resting ECG with QTc > 470 msec on 2 or more time points within a 24 hour period or family history of long QT syndrome
7. Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment
8. Concomitant use of known strong CYP3A inhibitors (eg. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (eg. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is 2 weeks.
9. Concomitant use of known strong (eg. phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John’s Wort ) or moderate CYP3A inducers (eg. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is 5 weeks for enzalutamide or phenobarbital and 3 weeks for other agents.
10. Persistent toxicities (>Common Terminology Criteria for Adverse Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia.
11. Patients with myelodysplastic syndrome/acute myeloid leukaemia or with features suggestive of MDS/AML.
12. Patients with symptomatic uncontrolled brain metastases. A scan to confirm the absence of brain metastases is not required. The patient can receive a stable dose of corticosteroids before and during the study as long as these were started at least 4 weeks prior to treatment. Patients with spinal cord compression unless considered to have received definitive treatment for this and evidence of clinically stable disease for 28 days.
13. Major surgery within 2 weeks of starting study treatment, or patients have not recovered from any effects of any major surgery.
14. Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to, uncontrolled ventricular arrhythmia, recent (within 3 months) myocardial infarction, uncontrolled major seizure disorder, unstable spinal cord compression, superior vena cava syndrome, extensive interstitial bilateral lung disease on High Resolution Computed Tomography (HRCT) scan or any psychiatric disorder that prohibits obtaining informed consent.
15. Patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication.
16. Breast feeding women.
17. Immunocompromised patients, e.g., patients who are known to be serologically positive for human immunodeficiency virus (HIV).
18. Patients with a known hypersensitivity to olaparib or any of the excipients of the product.
19. Patients with known active hepatitis (i.e. Hepatitis B or C) due to risk of transmitting the infection through blood or other body fluids
20. Previous allogenic bone marrow transplant or double umbilical cord blood transplantation (dUCBT)
21. Whole blood transfusions in the last 120 days prior to entry to the study (packed red blood cells and platelet transfusions are acceptable, for timing refer to inclusion criteria no.6)
