临床试验雷达

Histologic documentation: HER2 negative adenocarcinoma as defined by American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines (Bartley et al., Journal of Clinical Oncology \[JCO\] 2017) with known PD-L1 CPS (Any CPS is allowed, but should be known prior to registration)

Stage: unresectable or metastatic

Tumor site: esophagus, gastroesophageal junction, or stomach

Measurable disease or non-measurable but evaluable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1

No prior treatment for unresectable or metastatic disease

Prior neoadjuvant or adjuvant cytotoxic chemotherapy or adjuvant immunotherapy is allowed as long as it was completed at least 1 year prior to registration

Age >= 18 years

Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1

Absolute neutrophil count (ANC) >= 1,500/mm^3

Platelet count >= 100,000/mm^3

Creatinine =< 1.5 x upper limit of normal (ULN) OR calculated (calc.) creatinine clearance >= 30 mL/min

Total bilirubin =< 1.5 x ULN

Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3 x ULN (in patients with liver metastasis: =< 5 x ULN if clearly attributable to liver metastases)

Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial

Patients positive for human immunodeficiency virus (HIV) are eligible only if they meet all of the following:

• On effective anti-retroviral therapy
• Undetectable HIV viral load by standard clinical assay =< 6 months of registration

Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better

Patients who will receive nivolumab in addition to chemotherapy must not have any contraindications to immune checkpoint inhibitors

• Patients must not have active autoimmune disease that has required systemic treatment within 6 months prior to registration. Patients are permitted to receive immunotherapy if they have vitiligo, type I diabetes, 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 (precipitating event)
• Patients must not have a condition requiring systemic treatment with either corticosteroids (>10mg/day prednisone equivalents) or other immunosuppressive medications within 14 days prior to registration. Inhaled or topical steroids and adrenal replacement doses (=< 10mg/day prednisone equivalent) are permitted
• Patients must not have a history of noninfectious pneumonitis requiring steroids
• Patients with prior immune mediated adverse events related to immunotherapy that resulted in permanent treatment discontinuation with these agents are ineligible

This study includes the use of the mandatory patient completed measure, PRO-CTCAE. For this study the PRO-CTCAE is available in English, Spanish, Korean, Chinese (Simplified), and Russian, hence patients must be able to speak, understand and read in these languages. Ad-hoc translation of patient-reported measures is not permitted
