Tri Association in Patient With Advanced Epithelial Ovarian Cancer in Relapse

Inclusion Criteria:

Patients with platinum resistant relapse

* Female Patient must be ≥18 years of age.
* Signed informed consent and ability to comply with treatment and follow-up.
* Patient with Ovarian cancer, primary peritoneal cancer and/or fallopian-tube cancer, histologically confirmed (based on local histopathological findings): high grade serous or high grade endometrioid or other high grade epithelial non mucinous ovarian tumor.
* Patient who has completed at least one line of platinum-taxane chemotherapy, and presents with platinum resistant relapse (resistant disease defined by a tumor progression less than six months after the last dose of platinum) \[Note: the patient may have received one or even more line of platinum based chemotherapy\] OR Patient who is in platinum-sensitive relapse, whatever the line of chemotherapy given at relapse \[Note: any chemotherapy previously administered must have contained a platinum compound\]. The platinum sensitive relapse is defined by a tumor progression occurring more than six months after the last dose of platinum chemotherapy.
* Patient who didn't receive any of the tested drugs, or previously received either bevacizumab or olaparib BUT NOT the combination of both drugs.
* At least one measurable or evaluable lesion that can be accurately assessed at baseline by computed tomography (CT) (or magnetic resonance imaging \[MRI\] where CT is contraindicated) and is suitable for repeated assessment as per irRC. The baseline scan must be obtained within 28 days of first dose.
* Availability of a pre-treatment tumor sample (archival FFPE block or fresh biopsy if feasible) lasting of less than 3 months before inclusion into the study and performed AFTER the last chemotherapy administration.
* Patient not amenable to cytoreductive surgery at the time of relapse (surgery is not allowed during the protocole treatment).
* Patient must have normal organ and bone marrow function:

  * Hemoglobin ≥ 10.0 g/dL. (Transfusions is not allowed within 28 days before randomization)
  * Absolute neutrophil count (ANC) ≥ 1.5 x 109/L.
  * Platelet count ≥ 100 x 109/L. (Platelet transfusion or G-CSF administration is not allowed within 28 days before randomization)

  * Patient not receiving anticoagulant medication who has an International Normalized Ratio (INR) ≤ 1.5 and an Activated ProThrombin Time (aPTT) ≤ 1.5 x ULN. The use of full-dose oral or parenteral anticoagulants is permitted as long as the INR or APTT is within therapeutic limits (according to site medical standard). If the patient is on oral anticoagulants, dose has to be stable for at least two weeks at the time of inclusion.
  * Urine dipstick for proteinuria \< 2+. If urine dipstick is ≥ 2+, 24-hour urine must demonstrate \< 1 g of protein in 24 hours.

* Expectancy of at least 12 weeks
* Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
* Postmenopausal or evidence of non-childbearing status for women of childbearing potential prior to the first dose of study treatment (see protocol appendix 1).
