• Patients must not be receiving any other investigational agents.
• Patients with an uncontrolled intercurrent illness such as ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia or psychiatric illness/social situations that would limit compliance with study requirements will be excluded.
• Women must not be pregnant or breast-feeding due to potential harm to the fetus from carboplatin, paclitaxel, or nivolumab. All females of childbearing potential must have a blood test or urine study done within 2 weeks prior to registration to rule out pregnancy. Those enrolled on Arm B with nivolumab must agree to have a pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 24 hours of starting nivolumab to rule out pregnancy. A female of childbearing potential is any woman, regardless of sexual orientation or whether they have undergone tubal ligation, who meets the following criteria:
  • has not undergone a hysterectomy or bilateral oophorectomy; or
  • has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months).
• Women of childbearing potential (WOCBP) and sexually active males must either abstain from sexual intercourse for the duration of their participation in the study or agree to use both double barrier contraception and birth control pills or implants for at least one month (female patients) or one week (male patients) prior to the start of the study drug and continuing for 5 months after the last dose of study drug (for female patients) and for 7 months after the last dose of study drug (for male patients who are sexually active with WOCBP). Investigators shall counsel WOCBP and male subjects who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy.
• If patient says 'Yes' to "I choose to take part in the imaging study and will have the diffusion weighted magnetic resonance imaging (MRI) scans": patients must be able to tolerate MRI scans:
  • No history of untreatable claustrophobia;
  • No magnetic resonance (MR) incompatible implants/devices or metallic foreign bodies;
  • Weight compatible with limits imposed by the MRI scanner table.

STEP 2:

• Patient registration must not exceed 12 weeks from time of esophagectomy.
• Patients must have a post-operative ECOG performance status of 0-2
• Absolute neutrophil count ≥ 1,500/mcL (within less than or equal to 14 days prior to randomization).
• Platelets ≥ 100,000/mcL (within less than or equal to 14 days prior to randomization).
• Total bilirubin ≤ institutional upper limit of normal (ULN) (within less than or equal to 14 days prior to randomization).
• AST (SGOT)/ ALT (SGPT) ≤ 2.5 x institutional ULN (within less than or equal to 14 days prior to randomization).
• Serum creatinine ≤ 1.5 x institutional ULN (within less than or equal to 14 days prior to randomization).
• Patients must be disease free following esophagectomy as is demonstrated by having no evidence of disease on a post-surgical computed tomography (CT) scan. Patients must also have a negative surgical margin (R0 resection).
• Patients must not have an active, known or suspected autoimmune disease or a condition requiring treatment with steroids or immunosuppressive agents. Patients are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger.
• Patients must not have a condition requiring systemic treatment with either corticosteroids (> 10 mg/day prednisone equivalents) or other immunosuppressive medications with 14 days of study drug administration. Inhaled or topical steroids and adrenal replacement doses > 10 mg/day prednisone equivalents are permitted in the absence of active autoimmune disease.
• Patients must not be receiving any other investigational agents.
• Patients with an uncontrolled intercurrent illness such as ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia or psychiatric illness/social situations that would limit compliance with study requirements will be excluded.
• Women must not be pregnant or breast-feeding due to potential harm to the fetus from nivolumab or ipilimumab. All females of childbearing potential must have a blood test or urine study done (minimum sensitivity 25 IU/L or equivalent units of HCG) within 2 weeks prior to registration to rule out pregnancy. All patients must also agree to have a pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours of starting nivolumab to rule out pregnancy. Those enrolled on Arm D with ipilimumab must agree to have pregnancy tests within 72 hours of each ipilimumab administration to rule out pregnancy.
• Women of childbearing potential (WOCBP) and sexually active males must either abstain from sexual intercourse for the duration of their participation in the study or agree to use both double barrier contraception and birth control pills or implants for at least one month (female patients) or one week (male patients) prior to the start of the study drug and continuing for 5 months after the last dose of study drug (for female patients) and for 7 months after the last dose of study drug (for male patients who are sexually active with WOCBP). Investigators shall counsel WOCBP and male subjects who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy.
