Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase II, randomized, multi-centre study aiming at comparing the efficacy of Olaparib and Cediranib vs. weekly Paclitaxel in terms of progression free survival (PFS) in platinum refractory or resistant recurrent ovarian cancer.

Patients will be randomised in a 1:1:1 ratio to three treatment arms:

* Arm A: Paclitaxel 80 mg/mq every week
* Arm B: Cediranib 20 mg/day + Olaparib 600 mg / day (i.e. 300 mg BD) given every day
* Arm C: Cediranib 20 mg/day given 5 days per weeks + Olaparib 600 mg / day (i.e. 300 mg BD) given 7 days per weeks

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Both the experimental arms (Arm B and C) will be compared with Arm A in terms of PFS.

If both superior to the control (Arm A), they will be compared in terms of gastrointestinal safety.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patients affected by pathologically confirmed high-grade epithelial ovarian, fallopian tube, or primary peritoneal cancer.
2. Relapsed/progressive disease within 6 months from last platinum-based chemotherapy (platinum resistant/refractory disease).
3. Any line of treatment (after the first).
4. Any "last" chemotherapy line, including Paclitaxel, that should have been administered at least 6 months before the study beginning.
5. Patients must be women \> 18 years of age.
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 and no blood transfusions in the 28 days prior to entry/randomization - Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
* White blood cells (WBC) \> 3x109/L
* Platelet count ≥ 100 x 109/L
* Total bilirubin ≤ 1.5 x institutional Upper Limit of Normal (ULN)
* AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional Upper Limit of Normal, unless liver metastases are present in which case it must be ≤ 5x ULN
* Creatinine clearance estimated using the Cockcroft-Gault equation ≥51 mL/min,.
7. ECOG performance status 0-1.
8. Patients must have a life expectancy ≥ 16 weeks.
9. Evidence of non-childbearing status for women of childbearing potential (negative urine or serum pregnancy test within 28 days of study treatment, confirmed prior to treatment on day 1 or postmenopausal women. Postmenopausal status is defined as:

* Amenorrheic for 1 year or more following cessation of exogenous hormonal treatments
* LH and 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 sterilization (bilateral oophorectomy or hysterectomy)

12. BRCA1-2 mutation status known. In case of BRCA status unknown, the BRCA test must be performed before the randomization or, if not feasible, within the end-of the study treatment.
13. Provision of informed consent prior to any study specific procedures. In case of patients unable to give written informed consent, is necessary to have the subject or legal representative sign, but in any case a witness must be present and sign and date with the person providing informed consent.
