Brief Summary:
The DOMEC trial is designed as a Dutch Gynecological Oncology Group (DGOG), prospective, multi-center, phase II study for 55 patients with advanced (recurrent, refractory or metastatic) endometrial cancer or carcinosarcoma of the uterus to investigate the efficacy of the combination therapy of olaparib tablets and durvalumab IV.

Condition or disease Intervention/treatment Phase
Endometrial Neoplasms Uterine Neoplasms Endometrium Cancer Drug: PARP inhibitor and Anti-PD-L1 Phase 2

Detailed Description:

The prognosis of recurrent or persistent endometrial carcinoma not amenable to local therapy is poor. First line therapy exists of platinum-based chemotherapy or hormonal therapy. No standard subsequent-line therapy has been described.The combination of Poly(ADP-ribose) polymerases (PARP) inhibition and Programmed death-ligand 1 (PD-L1) blocking has great potential in the treatment of recurrent endometrial cancer. The DOMEC trial is designed to investigate this treatment combination among all molecular subgroups.

The DOMEC trial is designed as a DGOG, prospective, multi-center, phase II study for 55 patients with advanced (recurrent, refractory or metastatic) endometrial cancer, including carcinosarcoma of the uterus. Patients must have had one prior platinum-based chemotherapeutic regimen or not be able/willing to get chemotherapy. The aim is to investigate the efficacy of the combination therapy of olaparib tablets 300mg twice daily orally and durvalumab 1500mg by IV infusion every 4 weeks in terms of progression free survival. Secondary objectives are to investigate objective response rate, overall survival, safety and predictive biomarkers.

olaparib tablets 300mg twice daily orally and durvalumab 1500mg by IV infusion every 4 weeks
Drug: PARP inhibitor and Anti-PD-L1
olaparib tablets 300mg twice daily orally and durvalumab 1500mg by IV infusion every 4 weeks
Other Names:
  • olaparib
  • durvalumab
  • PARP inhibitor
  • Anti-PD-L1 Monoclonal Antibody




Primary Outcome Measures :
  1. Progression free survival (PFS) [ Time Frame: 6 months ]
    PFS will be counted from the date of registration until the first observation of radiological progressive disease according to RECIST 1.1 criteria or death due to any cause, whichever occurred first.


Secondary Outcome Measures :
  1. Objective response rate (ORR) [ Time Frame: 12 weeks ]
    according to RECIST 1.1 criteria

  2. Overall survival (OS) [ Time Frame: Through study completion, up to 36 months ]
    OS will be determined from the date of registration until death from any cause.

  3. Adverse events [ Time Frame: Through study completion, up to 36 months ]
    Assessed by NCI Common Terminology Criteria for adverse Events (CTCAE) version 5.0

  4. Predictive biomarkers in tumor biopsy [ Time Frame: At baseline ]
    MMRd/POLE, HR status, quantification of CD3,CD4,CD8,CD103,CD161,PD-1,LAG3,CTLA-4,NKG2A,GOXp3 positieve T cells, NK cells, percentage PD-L1 on myeloid cells/tumorcells, quantification of myeloid cell infiltration (CD68,CD14,CD33,CD163) in tumor biopsies.


Other Outcome Measures:
  1. Functional HRD assay (optional) [ Time Frame: At baseline ]
    Extra biopsy

  2. Immunological effects of PARP-1 inhibition (optional) [ Time Frame: Change From Baseline to 6 weeks and 12 weeks ]
    Tests for T cell and APC functionality measured by the measurement of recall antigen responses and mixed lymphocyte cultures, respectively, the levels of regulatory T cells, activation markers on T cells and DC).

  3. Predictive biomarkers for PD-L1 blocking in blood (optional) [ Time Frame: Change From Baseline to 6 weeks and 12 weeks ]
    e.g. monocyticMDSC levels, DC levels, inhibitory marker expression, neutrophil-to-lymphocyte ratio, absolute lymphocyte count, T-cell reactivity during PD-L1 blocking, T-cell cytokine expression after SEB activation
