Overview
Brief Summary
The main objective of the trial is to assess the feasibility and the safety of the addition of immunotherapy with PD-1 antibody nivolumab +/- CTLA-4 antibody ipilimumab to concomitant chemoradiation therapy (CRT) in inoperable patients with early or locally advanced oesophageal cancer and to select the more promising experimental arm among the two possible combinations in terms of activity (based on progression free survival (PFS) at 12 months according to RECIST 1.1) for further evaluation in a phase III trial.
The secondary objectives will aim to evaluate progression-free survival, failure-free survival and overall survival and pattern of progression (including incidence of distance metastasis).

Arms & Interventions
Arm A: Chemoradiation + Nivolumab
All patients will receive standard fractionation radiation therapy (RT) scheme: 50Gy in 25 fractions over 5 weeks (i.e. 2Gy per fraction), concurrently with 3 cycles of 2 weeks of FOLFOX followed by 3 cycles of 2 weeks of FOLFOX without RT. Induction phase: Nivolumab IV 240 mg on days 1, 15 and 29 followed by a maintenance phase (to start on day 43) of Nivolumab IV 240 mg q2 weekly for up to 1 year.

Outcomes
Primary Outcomes
12-Month Progression-free survival using RECIST 1.1
Time Frame: 3.8 years from first patient in
The analysis of the 12-Month Progression-free survival rate (PFS-12) will be done when all patients achieved at least 15 months follow-up (12 months for the primary endpoint plus 100 days after the end of the protocol treatment).
Secondary Outcomes
- Best overall response according to RECIST 1.1(3.8 years from first patient in)
- Pattern of first cause of progression (either local relapse/progression,either regional relapse/progression, either distant metastasis)(3.8 years from first patient in)
- Progression-free survival using RECIST 1.1(3.8 years from first patient in)
- Failure-free survival(3.8 years from first patient in)
- Overall survival(3.8 years from first patient in)
- Percentage of patients receiving the planned chemoradiation(3.8 years from first patient in)
- Relative dose intensity of oxaliplatinum(3.8 years from first patient in)
- Relative dose intensity of 5FU(3.8 years from first patient in)
