Clinical Trial Summary

CIME is a multicenter, randomised, comparative, open-label phase III study aiming to compare the survival of patients suffering from MSI-H/dMMR locally advanced or metastatic oeasogastric adenocarcinoma treated by a bi-immunotherapy (experimental arm) versus standard current treatment (FOLFOX/XELOX + nivolumab : standard arm).

Anticonvulsant therapy at a stable dose is permitted. A minimal wash-out period of 10days for corticosteroids is required. - Patients with other malignancy unless this malignancy is not expected to interfere with the evaluation of study endpoints (basal or squamous cell carcinoma of the skin, in-situ carcinoma of the cervix, localized prostate cancer), or with no evidence of disease for = 2 years. - Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients. - of ILD or non-infectious pneumonitis requiring glucocorticoids. - History of allogeneic organ transplant. - Psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the study. - Patient with peripheral sensory neuropathy with functional impairment. - Patients with clinically significant active heart disease or myocardial infarction within 6 months, history of uncontrolled or symptomatic cardiac disease. - Patient with recent (within 7d before C1D1) or concomitant treatment with brivudine. - Patient with complete absence of dihydropyrimidine dehydrogenase (DPD) activity (blood uracil level = 150 ng/mL) or partial deficit in DPD (i.e. blood uracil level between = 16 ng/ml and < 150 ng/mL) - Patients with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) within 14 days or another immunosuppressive medication within 30 days of the first dose of study treatment.

Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever and BCG. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however intranasal influenza vaccines (e.g. Flu-Mist®) are live attenuated vaccines, and are not allowed. - Active autoimmune disease or history of autoimmune disease that required systemic treatment within 2 years of the start of study treatment (i.e., with use of disease-modifying agents or immunosuppressive drugs). - History or current evidence of any condition, co-morbidity, therapy, any active infections, or laboratory abnormality that might confound the results of the study, interfere with the patient's participation for the full duration of the study, or is not in the best interest of the patient to participate, in the opinion of the treating Investigator. - Patients with documented: - Active hepatitis B (chronic or acute; defined as having a positive hepatitis B surface antigen [HBsAg] test at screening) unless their HBV is stably controlled on nucleoside analogs (eg entecavir or tenofovir) which will be continued for the duration of the study. Note: Patients with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as the presence of hepatitis B core antibody [anti-HBc] and absence of HBsAg) are eligible. HBV DNA test must be performed in these patients prior to C1D1. - Active hepatitis C. Patients positive for hepatitis C virus (HCV) antibody are eligible only if PCR is negative for HCV RNA, or - HIV infection - Prior organ or bone marrow transplant. - Pregnant or lactating women.
