Brief summary: This is an open-label, prospective, multicenter, randomized Phase III, clinical trial evaluating the efficacy and safety of trabectedin in BRCA1 and BRCA2 mutation carrier and BRCAness phenotype advanced ovarian cancer patients in comparison to physician' choice chemotherapy.

Arm A: Trabectedin 1.3 mg/mq d1 q 21 in 3 hours (central line) Arm B: Pegylated Liposomal Doxorubicin 40 mg/mq q 28 or Topotecan 4 mg/mq dd 1,8,15 q 28 or Gemcitabine 1000 mg/mq dd 1, 8, 15 q 28 Weekly Paclitaxel 80 mg/mq gg 1, 8, 15 q 28 Carboplatin AUC 5-6 q 21 or 28

Patients will be randomly assigned in a 1:1 ratio to treatment arms. During the randomization process, patients will be stratified by

* Platinum sensitivity
* Measurable disease
* Number of previous chemotherapy lines \> vs \< 3
* BRCA mutational status

Detailed description: Subjects will be randomized in a 1:1 ratio to receive one of the following treatments: Arm A: Trabectedin 1.3 mg/m2 d1 q 21 in 3 hours (central line) Arm B: Pegylated Liposomal Doxorubicin 40 mg/mq q 28 or Topotecan 4 mg/ m2 dd 1,8,15 q 28 or Gemcitabine 1000 mg/mq dd 1, 8, 15 q 28 Weekly Paclitaxel 80 mg/ m2 dd 1, 8, 15 q 28 Carboplatin AUC 5-6 q 21 or 28 Randomization will be stratified based on platinum-free interval (PFI) (PFI ≥ 0 and ≤ 6 months vs. PFI \> 6 months), presence / absence of measurable disease/number of previous chemotherapy lines, germline BRCA mutational status vs BRCAness phenotype.

Platinum-free interval (PFI) is defined as the time from the last dose of the platinum containing regimen until the first date progression.

Subjects will continue to receive chemotherapy treatment until disease progression (clinical progression meant as global deterioration in health status attributable to the disease requiring a change in therapy without objective evidence of progression is considered progression of disease), intolerability, patient refusal, investigator decision or death from any cause.

Subjects will be evaluated every 12 weeks ± 1 week by Response Evaluation Criteria in Solid Tumors (RECIST 1.1) for objective radiographic response and radiographic disease progression.

Eligibility criteria: Inclusion Criteria:

   3. Platinum sensitive patients who are not able to receive or not willing to receive other platinum treatments
4. Measurable and evaluable disease per RECIST 1.1(Subjects with isolated rising CA-125 without radiologically visible disease are excluded)
5. ECOG performance status 0 or 1
6. No limits in the number of previous chemotherapy lines, previous treatment with parp inhibitors is allowed
7. Left Ventricular Ejection Fraction (LVEF) ≥ institutional lower limit normal
8. Life expectancy of at least 3 months
9. Adequate organ functions:

   1. Hematopoietic: Absolute neutrophil count ≥ 1,500/mm3; Platelet count ≥ 100,000/mm3; Hemoglobin ≥ 9 g/dl
   2. Hepatic: AST and ALT ≤ 1.5 times upper limit of normal (ULN)\* ; Alkaline Phosphatase ≤ 2.5 times ULN\* ; Bilirubin ≤ 1.5 times ULN. NOTE: \* ≤ 3 times ULN if liver metastases are present
   3. Renal: Creatinine Clearance ≥ 45 ml/min or Serum Creatinine ≤1.5 x ULN
   4. Serum Albumin \>2.5 g/dl
10. No other invasive malignancy within the past 3 years except non-melanoma skin cancer or in situ cervical cancer (patients with previous cancers may be enrolled providing that no recurrences have be reported in the last 3 years)
11. Written Informed Consent
12. Adequately recovered from the acute toxicity of any prior treatment
13. For agents in the standard arm, also refer to the local prescribing information with regards to warnings, precautions, and contraindications

Exclusion Criteria:

1. Prior exposure to trabectedin
2. Known hypersensitivity to any of the components of the trabectedin i.v. formulation or dexamethasone
3. Subjects with borderline ovarian cancer, ie. Subject with low malignant potential tumors are excluded
4. Less than 2 reported responses to platinum (i.e. subsequent recurrences at least 6 months after the first and the second platinum based treatment), unless BRCA mutation is documented.
5. Less than 4 weeks from last dose of therapy with any investigational agent, or chemotherapy
6. History of another neoplastic disease (except basal cell carcinoma or cervical carcinoma in situ adequately treated) unless in remission for 3 years or longer
7. Known clinically relevant CNS metastases, unless treated and asymptomatic
8. Other serious illnesses, such as:

   1. Congestive heart failure or angina pectoris; myocardial infarction within 1 year before enrolment; uncontrolled arterial hypertension or arrhythmias.
   2. Psychiatric disorder that prevents compliance with protocol.
   3. Active viral hepatitis; or chronic liver disease.
   4. Active infection.
   5. Any other unstable medical conditions.
