This phase II/III trial studies the usefulness of treatment with nivolumab and ipilimumab in addition to standard of care chemotherapy and radiation therapy in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery. Immunotherapy with antibodies, such as nivolumab and ipilimumab, may remove the brake on the body's immune system and may interfere with the ability of tumor cells to grow and spread. Chemotherapy and radiation therapy may reduce the tumor size and the amount of normal tissue that needs to be removed during surgery. A combined treatment with nivolumab and ipilimumab, chemotherapy, and radiation therapy might be more effective in patients with esophageal and gastroesophageal junction adenocarcinoma who are undergoing surgery.
PRIMARY OBJECTIVES: I. To assess the pathologic complete response (pathCR) rate following administration of neoadjuvant carboplatin, paclitaxel and radiation therapy versus neoadjuvant carboplatin, paclitaxel, radiation therapy and nivolumab in patients with a resected locoregionally advanced esophageal or gastroesophageal junction adenocarcinoma. II. To assess the disease-free survival (DFS) following administration of adjuvant nivolumab and ipilimumab versus adjuvant nivolumab in patients with a resected locoregionally advanced esophageal or gastroesophageal junction adenocarcinoma who received neoadjuvant treatment with carboplatin, paclitaxel and radiation therapy with or without nivolumab. SECONDARY OBJECTIVES: I. To assess the overall survival (OS) following administration of adjuvant nivolumab and ipilimumab versus nivolumab in patients with a resected locoregional esophageal or gastroesophageal junctional adenocarcinoma who received neoadjuvant treatment with carboplatin, paclitaxel and radiation therapy with or without nivolumab. II. To assess the disease free survival (DFS) following administration of neoadjuvant carboplatin, paclitaxel, and radiation therapy with or without nivolumab in patients with a locoregional esophageal or gastroesophageal junction adenocarcinoma. III. To assess the toxicity associated with the administration of neoadjuvant nivolumab in combination with carboplatin, paclitaxel and radiation therapy in patients with a locoregional esophageal or gastroesophageal junction adenocarcinoma. IV. To assess the toxicity associated with the administration of adjuvant nivolumab and ipilimumab versus adjuvant nivolumab in patients with a resected locoregional esophageal or gastroesophageal junction adenocarcinoma who received neoadjuvant treatment with carboplatin, paclitaxel and radiation therapy with or without nivolumab. OUTLINE: STEP I: Patients are randomized to 1 of 2 arms. ARM A: Patients receive carboplatin intravenously (IV) and paclitaxel IV once weekly and undergo radiation therapy once daily (QD) (Monday-Friday) beginning on day 1 of each cycle. Cycles repeat every week for up to 5 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo a computed tomography (CT) or positron emission tomography (PET) scan during screening and follow-up and undergo collection of blood samples throughout the trial. ARM B: Patients receive carboplatin, paclitaxel, and radiation therapy as in Arm A. Patients also receive nivolumab IV over 30 minutes on days 1 and 15 of each cycle. Cycles repeat every week for up to 5 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo a CT or PET scan during screening and follow-up and undergo collection of blood samples throughout the trial. STEP II: Patients are randomized to 1 of 2 arms following standard of care surgery. ARM C: Patients receive nivolumab IV over 30 minutes on day 1 of each cycle. Treatment repeats every 4 weeks for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo a CT scan and collection of blood samples throughout the trial. ARM D: Patients receive nivolumab as in Arm C and receive ipilimumab IV over 90 minutes on day 1 of cycles 1 and 4 and day 15 of cycles 2 and 5. Treatment repeats every 4 weeks for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo a CT scan and collection of blood samples throughout the trial. After completion of study treatment, patients are followed up every 3 months for 2 years, and then every 6 months for up to 5 years.

Pathologic complete response (Step I)
The study with compare the pathologic complete response of Arm A and Arm B using a one-sided 0.10 level chi-squared test for proportions.
Time frame: Up to 5 weeks
Disease-free survival (DFS) (Step 2)
DFS measured from the adjuvant treatment randomization will be the endpoint of the adjuvant portion of the study and to achieve the desired power it is expected that patients will be followed for an additional year post completion of accrual to the adjuvant portion. The DFS comparison will be between patients randomized to Arm C (nivolumab) versus Arm D (nivolumab plus ipilimumab) using a one-sided 0.10 level stratified log rank test.
Time frame: From the adjuvant treatment randomization assessed for up to 7 years
Incidence of adverse events
Graded according to Common Terminology Criteria for Adverse Events version 5.0. Toxicity will be evaluated among all treated patients regardless of eligibility and interim analyses of toxicity are performed twice yearly. The study will have sufficient precision to provide 95% confidence intervals on toxicity
Time frame: Up to 7 years
Overall survival
Analyses will be descriptive in nature and will not follow any formal interim monitoring.
Time frame: From the time of first randomization up to 7 years
DFS
The DFS comparison will be between patients randomized to Arm C (nivolumab) versus Arm D (nivolumab plus ipilimumab) using a one-sided 0.10 level stratified log rank test.
Time frame: From the time of first randomization up to 7 years
