Inclusion Criteria

- Histologically confirmed, resectable GC or AEG (AEG I-III) (uT2, uT3, uT4, any N category, M0), or any T N+ M0 patient, with the following specifications:
- Exclusion of distant metastases by CT or MRI of abdomen, pelvis, and thorax, bone scan or MRI (if bone metastases are suspected due to clinical signs). Exclusion of the infiltration of
any adjacent organs or structures by CT or MRI
- Measurable target tumors using standard imaging techniques or clinical evaluation and significant FDG-uptake in PET

- Female and male patients = 18. Patients in reproductive age must be willing to use adequate contraception during the study and for 6 months after the end of treatment. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of study drug.

- Eastern Cooperation Oncology Group (ECOG) = 1

- Adequate hematological, hepatic and renal function parameters:
o Leukocytes = 2000/mm³, platelets = 100,000/mm³, absolute neutrophil count (ANC) =1500/µL, hemoglobin =9 g/dL (5.58 mmol/L),
o Adequate coagulation function as defined by International Normalized Ratio (INR) = 1.5, and a partial thromboplastin time (PTT) = 5 seconds above the upper limit of normal (ULN) (unless receiving anticoagulation therapy). Patients receiving warfarin/ phenprocoumon must be switched to low molecular weight heparin and have achieved stable coagulation profile prior to randomization.
o Serum creatinine = 1.5 x ULN of normal or calculated creatine clearance of < 50 mL/min (using Cockroft-Gault formula)
o Bilirubin = 1.5 x ULN, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) = 3.0 x ULN, alkaline phosphatase = 6 x ULN, Serum albumin =2.8 g/dL
- Left ventricular ejection fraction (LVEF) assessment with documented LVEF =50% by either trans-thoracic echocardiography (TTE) or multigated acquisition (MUGA) (TTE preferred test) within 6 months from first study drug administration
- Patient able and willing to provide written informed consent and to comply with the study protocol and with the planned surgical procedures
- Optional, if further IO combination will be added per amendment: positive Biomarker expression (i.e. LAG-3) if data from previous clinical trials support the use of IO combination in selected patients

Exclusion Criteria

1. Active or history of autoimmune disease or immune deficiency, including, but not limited to, myasthenia gravis, myositis, autoimmune hepatitis, systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, anti-phospholipid antibody syndrome, Wegener granulomatosis, Sjögren syndrome, Guillain-Barré syndrome, multiple sclerosis, vasculitis, or glomerulonephritis with the following exceptions:
-- Patients with a history of autoimmune-related hypothyroidism who are on thyroid replacement hormone are eligible for the study.
-- Patients with controlled type 1 diabetes mellitus who are on an insulin regimen are eligible for the study.
-- Skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic immunosuppressive treatment, in particular corticosteroids are permitted to enroll
2. Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration
3. Uncontrolled or significant cardiovascular disease including, but not limited to, any of the following:
o Myocardial infarction (MI) or stroke/transient ischemic attack (TIA) within the 6 months prior to consent
o Uncontrolled angina within the 3 months prior to consent
o Any history of clinically significant arrhythmias (such as ventricular tachycardia, ventricular fibrillation, or torsades de pointes)
o QTc prolongation > 480 msec
o History of other clinically significant cardiovascular disease (i.e., cardiomyopathy, congestive heart failure with New York Heart Association [NYHA] functional classification III-IV, pericarditis, significant pericardial effusion, significant coronary stent occlusion, deep venous thrombosis, etc )
o Cardiovascular disease-related requirement for daily supplemental oxygen
o History of two or more MIs OR two or more coronary revascularization procedures
o Subjects with history of myocarditis, regardless of etiology
o Troponin T (TnT) or I (TnI) > 2 × institutional ULN. Subjects with TnT or TnI levels between > 1 to 2 × ULN will be permitted if repeat levels within 24 hours are 1 x ULN.
4. Active malignancy or a prior malignancy within the past 3 years
o Patients with completely resected basal cell carcinoma, cutaneous squamous cell carcinoma, cervical carcinoma in-situ, breast carcinoma in-situ, and patients with isolated elevation in prostate-specific antigen in the absence of radiographic evidence of metastatic prostate cancer are eligible for the study.
5. Positive test for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS). NOTE: Testing for HIV must be performed at sites where mandated locally.
6. Any positive test result for hepatitis B virus or hepatitis C virus indicating presence of virus, e.g., hepatitis B surface antigen (HBsAg, Australia antigen) positive, or hepatitis C antibody (anti-HCV) positive (except if HCV RNA negative).
7. Any other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding that contraindicates the use of an investigational drug, may affect the interpretation of the results, or may render the patient at high risk from treatment complications
