Brief Summary:
Indoleamine 2,3 dioxygenase 1 (IDO 1) is the major enzyme catabolising the Tryptophan outside the liver. It has been shown that its plays a important role in generating a immunosuppressive micro-environment in tumors. IDO expression has been shown by Hennequart et al. to be driven by Cyclooxygenase-2 (COX-2) expression. The investigator's team also shown that anti-COX2, celecoxib, can in a xenograft models of ovarian cancer decrease IDO1 expression and result in an infiltration of the tumor by T cells. The investigator proposed then to conduct a proof of concept study to evaluate the effect of pre-operative short administration of Celecoxib on IDO expression and Immune cells tumors infiltration, in patients with endometrial cancer. Indeed, this tumor type is well known to express frequently a high level of IDO.

Detailed Description:
Indoleamine 2,3-dioxygenase 1 (IDO1) is an enzyme that regulates immune responses by degrading tryptophan, which is required for efficient T-cell activation. IDO1 expression is limited in normal tissues but is induced by IFN-gamma in inflammatory tissues, to prevent excessive T-cell activity. The investigator's collaborators previously reported that IDO1 is expressed in many human tumours, and that pharmacological inhibition of IDO1 leads to immune rejection of IDO1+ mouse tumours. Based on these results, IDO1 inhibitors are now in clinical development. A first inhibitor, Epacadostat, showed encouraging results combined with anti- Programmed Cell Death -1 (PD-1) antibodies. Tumoural expression of IDO1 can be induced by IFN-gamma, which is produced by tumour-infiltrating lymphocytes (TIL), and represents a mechanism of adaptive immune resistance. However, other tumours express IDO1 in the absence of TIL and Interferon-gamma (INF gamma). This seems to be particularly frequent in endometrial carcinoma. This constitutive IDO1 expression prevents T-cell infiltration and represents a mechanism of intrinsic immune resistance. The investigator's collaborators recently showed that constitutive tumoural expression of IDO1 was triggered by cyclooxygenase-2 (COX-2) and mediated by autocrine prostaglandin-E2 (PGE2) signaling via the Protein Kinase C (PKC) and phosphoinositide 3-kinase (PI3K) pathways. Constitutive IDO1 expression was reduced by COX-2 inhibitors in vitro. Celecoxib is a well-known and widely used anti-inflammatory drug. It is a specific inhibitor of COX-2. In vivo, celecoxib induced immune rejection of IDO1-expressing human tumour xenografts, while reducing IDO1 expression and promoting T-cell infiltration. These preclinical results suggest that COX-2 inhibition in patients carrying tumours expressing IDO1 constitutively will decrease IDO1 expression, increase T-cell infiltration and might increase responsiveness to anti-PD-1/ Programmed Cell Death Ligand-1(PD-L1) therapy and thereby exert enhanced anti-tumour activity. The investigators wish to obtain clinical evidence that celecoxib can induce these first two effects

Drug Information available for: Celecoxib

Arm Intervention/treatment
Experimental: Celecoxib
Patients with confirmed primary endometrioid adenocarcinoma eligible for first line curative surgery will receive celecoxib 400 mg twice a day, for 15 days before the curative surgery for their endometrial cancer. The patients will undergo an endometrial biopsy at the inclusion and during the surgery.
Drug: Celecoxib 200mg capsule
Patient confirmed with endometrial cancer will received twice daily 200 mg Celecoxib, 15 days before the surgery.
Other Name: Cyclooxygenase-2 (COX-2) inhibitor




Primary Outcome Measures :
  1. Reduction of tumoural cells expression IDO after celecoxib treatment. If more than 10% of all the tumoural cells have a staining for IDO, the tumour is considered as IDO (+), if less than 10%. [ Time Frame: after 15 days of celecoxib administration ]

    Reduction of Tumoral IDO expression after Celecoxib treatment by immunohistochemistry, digital identification of the cells and phenotype and computer count of IDO positive cells inside de tumour (then total number compared before and after the treatment). If more than 10% of all the tumoural cells have a staining for IDO, the tumour is considered as IDO (+), if less than 10%, it is considered as (-).

    Based on animal models, the treatment with celecoxib should decreases IDO expression in tumoural cells, allowing an immune cells tumoural's infiltration.


  2. Modification of tumoural T Cells infiltration after the treatment with celecoxib. The number of Cluster of Differenciation (CD) 4 and CD8 T cells will be counted before and after the treatment. [ Time Frame: after 15 days of celecoxib administration ]
    Observed the modification of the T cell tumoral's infiltration after the celecoxib treatment by immunohistochemistry, digital identification of the cells and phenotype and computer count of the different T cells population inside de tumour (then total number compared before and after the treatment). The number of CD4 and CD8 T cells will be counted before and after the treatment and the median of all the sample before and after the treatment will be compared to assess if there is a significant difference of total number of T cells before and after the treatment. Unit= nombre of CD4 and CD8 T Cells. Based on animal model, the investigators expect to have a significant increase of T cells infiltration after the celecoxib treatment


Secondary Outcome Measures :
  1. Number of participants with treatment-related adverse events as assessed by Common Terminology Criteria for Adverse Event Version 4.0 (CTCAE v4.0). [ Time Frame: from the first intake of the celecoxib to one day after the surgery ]

    Assessment and scaling of adverse events according to CTCAE v4.0, Grade 1 Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 Moderate; minimal, local or noninvasive intervention indicated;

    Grade 3 Severe or medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care Grade 4 Life-threatening consequences; urgent intervention indicated. Grade 5 Death related to Adverse Event.
