Brief Summary:
The aim of the study is to explore a prognostic clinical and molecular biomarker profile in a population of BRCA wild-type recurrent high-grade ovarian cancer patients treated with olaparib as maintenance after response to a platinum based therapy as platinum sensitive recurrence treatment.

Condition or disease Intervention/treatment Phase
BRCA Wild Type Platinum Sensitive Recurrent Ovarian Cancer Drug: Olaparib tablets Phase 2

Detailed Description:
This is a single arm, open-label Phase 2 study designed to evaluate the effect of maintenance olaparib treatment after response to platinum-based chemotherapy in patients with BRCA wild type platinum sensitive recurrent ovarian cancer. The goal is to identify a clinical and molecular profile able to select a group of patients, treated with olaparib as maintenance, with a favorable prognosis.

Criteria

Inclusion Criteria

  1. Patients must be ≥ 18 years of age
  2. Female patients with histologically diagnosed relapsed high grade ovarian cancer (including primary peritoneal and /or fallopian tube cancer)
  3. Documented absence of somatic and germline mutations of BRCA1 or BRCA2 genes, that is predicted to be deleterious or suspected deleterious
  4. ECOG Performance Status of 0-2
  5. Patients must have a life expectancy of at least 16 weeks
  6. Signed informed consent obtained prior to initiation of any study-specific procedures and treatment as confirmation of the patient's awareness and willingness to comply with the study requirements
  7. Availability of tumor and blood samples for molecular analyses
  8. Patients who have received at least 2 previous line of platinum containing therapy prior to randomization

    • For the penultimate chemotherapy course prior to enrolment on the study:
    • Patient defined as platinum sensitive after this treatment, defined as having disease progression greater than 6 months after completion of their last dose of platinum chemotherapy

For the last chemotherapy course immediately prior to randomization on the study:

  • Patients must be, in the opinion of the investigator, in radiologic response (partial or complete response) according to RECIST 1.1 criteria, or may have no evidence of disease (if optimal cytoreductive surgery was conducted prior to chemotherapy), and no evidence of a rising CA-125 compared to nadir value, following completion of this chemotherapy course i. Patient must have received, at least 4 cycles of a platinum based chemotherapy regimen (e.g. carboplatin or cisplatin per standard clinical practice) j. Patients must be enrolled within 8 weeks of their last dose of chemotherapy k. Maintenance treatment, including bevacizumab, is allowed at the end of the penultimate platinum regimen l. 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 m. Patients must have normal organ and bone marrow function measured within 28 days prior to administration of study treatment as defined below:
  • Hemoglobin ≥ 10.0 g/dL with no blood transfusion 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) (x F)a serum creatinine (mg/dL) x 72 a where F=0.85 for females and F=1 for males
