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).
Interventions
DRUGNivolumab
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.
DRUGIpilimumab
Induction phase: Ipilimumab IV 1 mg/kg on day 1 followed by a maintenance phase (to start on day 43) of Ipilimumab IV 1 mg/kg q6 weekly for up to 1 year.
OTHERChemoradiation
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 (oxaliplatin 85 mg/m2, leucovorin 200 mg/m2, bolus fluorouracil 400 mg/m2, and infusional fluorouracil 1600 mg/m2 over 48 h), followed by 3 cycles of 2 weeks of FOLFOX without RT.
