This is a phase IIB, national, randomized, double-blinded, comparative, multi-center study, to assess the efficacy of Olaparib as maintenance after a platinum based chemotherapy in patients with Advanced or metastatic endometrial cancer


Approximately 147 patients will be randomized using an Interactive Voice Response System / Interactive web system (IVR/IWR system) in a 2:1 ratio to the treatments as specified below :

  • Olaparib tablets per os 300 mg twice daily,
  • Placebo tablets per os 300 mg twice daily.

Before randomization to the study :

  • Patient should be without evidence of disease (NED), or in clinical complete response or in partial response or stable.
  • Patient must have completed a minimum of 4 cycles of first line platinum based chemotherapy (recommended chemotherapy is carboplatine AUC 5 plus paclitaxel 175 mg/m2).

Patient will be stratified according to :

  • P53 and MMR Immunohistochemistry, (Y/N)
  • Response to previous chemotherapy line (Objective response versus Stable)

Patients will receive Olaparib/Placebo up to disease progression.

Treatment Placebo oral capsule, Olaparib Oral Capsule
Clinical Study IdentifierNCT03745950

As this study will include patients in France, a subject will be eligible for randomization in this study only if either affiliated to, or a beneficiary of, a social security category
For inclusion in ancillary studies If a patient declines to participate in the
optional Biomarker/pharmacogenetic research, there will be no penalty or loss
of benefit to the patient. The patient will not be excluded from other aspects
of the study
