Overview
PRIMARY OBJECTIVE:
I. To determine if overall survival (OS) is improved in patients who received mFOLFIRINOX +/- nivolumab in comparison to FOLFOX +/- nivolumab as first-line chemotherapy for metastatic gastroesophageal adenocarcinoma.
SECONDARY OBJECTIVES:
I. To compare other indices of efficacy, including progression-free survival, objective response rates and duration of response between both treatment arms.
II. To evaluate safety and tolerability associated with treatment in each of the treatment arms.
III. To evaluate the proportion of patients receiving second line of therapy in both arms.
IV. To evaluate tolerability of the treatment in both arms using Patient Reported Outcomes-Common Terminology Criteria for Adverse Events (PRO-CTCAE).
EXPLORATORY OBJECTIVES:
I. Exploratory correlative markers will also be measured and evaluated within and between arms to better assess mechanisms and prognostic impact of markers on impact. These will include baseline PD-L1 combined positive score (CPS) and cell free deoxyribonucleic acid (cfDNA) before and after treatment.
II. To evaluate and assess the feasibility and compliance associated with not centrally collecting perceived attribution of protocol treatment to reported adverse events.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive fluorouracil intravenously (IV), leucovorin calcium IV, oxaliplatin IV, and irinotecan IV on study and nivolumab IV as clinically indicated. Patients undergo magnetic resonance imaging (MRI) and a computed tomography (CT) scan throughout the trial. Patients may also undergo blood sample collection on study.
ARM II: Patients receive fluorouracil IV, leucovorin calcium IV, and oxaliplatin IV on study and nivolumab IV as clinically indicated. Patients undergo MRI and a CT scan throughout the trial. Patients may also undergo blood sample collection on study.
