Details and patient eligibility

About

This is a Phase III randomised, double-blind, multi-centre study to evaluate the efficacy and safety of durvalumab in combination with standard of care platinum based chemotherapy and bevacizumab followed by maintenance durvalumab and bevacizumab or durvalumab, bevacizumab and olaparib in patients with newly diagnosed advanced ovarian cancer.

Full description

Eligible patients will be those patients with newly diagnosed, histologically confirmed advanced (Fédération Internationale de Gynécologie et d'Obstétrique [FIGO] Stage III-IV) ovarian, primary peritoneal cancer and/or fallopian-tube cancer. All patients should be candidates for cytoreductive surgery which could be conducted as immediate upfront primary surgery following diagnosis or can be conducted after initiation of platinum based neoadjuvant chemotherapy. All patients should be eligible to start first line platinum based chemotherapy in combination with bevacizumab. The study aims to evaluate the efficacy and safety of standard of care (SoC) platinum-based chemotherapy and bevacizumab followed by maintenance bevacizumab either as monotherapy, or in combination with durvalumab, or in combination with durvalumab and olaparib. Therefore, this study aims to see which combination allows patients to live longer without the cancer coming back or getting worse. The study is also looking to see which combination makes patients live longer and how the treatment and the cancer affects their quality of life.

  • Patients must be aged ≥18 years of age. For patients enrolled in Japan that are aged <20 year
  • All patients should be candidates for cytoreductive surgery either: upfront primary surgery OR plan to undergo chemotherapy with interval debulking surgery
  • Evidence of presence or absence of BRCA1/2 mutation in tumour tissue
  • Mandatory provision of tumour sample for centralised tBRCA testing
  • ECOG performance status 0-1
  • Patients must have preserved organ and bone marrow function
  • Postmenopausal or evidence of non-childbearing status for women of childbearing potential: negative urine or serum pregnancy test

Key Exclusion Criteria:

History of another primary malignancy except for:

  • Malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of study treatment and of low potential risk for recurrence (patients who have received prior adjuvant chemotherapy for early stage breast cancer may be eligible, provided that it was completed ≥3 years prior to registration, and that the patient remains free of recurrent or metastatic disease)
  • Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
  • Adequately treated carcinoma in situ without evidence of disease
  • Endometrial cancer FIGO Stage IA, Grade 1 or Grade 2
