This phase III trial compares the effect of modified fluorouracil, leucovorin calcium, oxaliplatin, and irinotecan (mFOLFIRINOX) with or without nivolumab to the effect of modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX) with or without nivolumab for the treatment of patients with advanced, unresectable, or metastatic HER2 negative esophageal, gastroesophageal junction, or gastric adenocarcinoma. The usual approach for patients who are not in a study is treatment with FOLFOX with some receiving an immunotherapy drug, either nivolumab or pembrolizumab, in addition to FOLFOX chemotherapy. The usual approach is defined as care most people get for cancer in the stomach, esophagus, or gastroesophageal junction. Fluorouracil is in a class of medications called antimetabolites. It stops cells from making DNA and may kill tumor cells. Leucovorin in a class of medications called folic acid analogs. When used with fluorouracil it enhances the effects of this chemotherapy drug. Irinotecan is in a class of antineoplastic medications called topoisomerase I inhibitors. It blocks a certain enzyme needed for cell division and DNA repair, and may kill cancer cells. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill cancer cells. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. Some patients on this trial will receive nivolumab, in addition to mFOLFOX or mFOLFIRINOX chemotherapy. mFOLFIRINOX with or without nivolumab may be more effective than mFOLFOX with or without nivolumab by shrinking the tumor in patients with advanced, unresectable, or metastatic HER2-negative esophageal, gastroesophageal junction, or gastric adenocarcinoma.
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.
Inclusion Criteria:
Not pregnant and not nursing, because this study involves an agent that has known genotoxic, mutagenic and teratogenic effects
* Therefore, for women of only, a negative serum or urine pregnancy test done =\< 7 days prior to registration is required
Patients positive for (HIV) are eligible only if they meet all of the following:
Patients who will receive nivolumab in addition to chemotherapy must not have any to immune checkpoint inhibitors
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
HER2 is a protein, made from the ERBB2 gene, that drives the growth of some cancers. A study may look for a level of the protein, extra copies of the gene, or a particular change in it.
In breast cancer, protein tests are read as HER2-positive, HER2-low or HER2-negative; other cancers use their own rules. Check which test result the study requires.
PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.
PD-L1 can also be measured in a tumor sample. Some scores count stained tumor cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumor measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumor visible on a scan does not by itself rule you out.
The standard rules for measuring tumors on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumor 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumor. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Ancillary studies
Overall survival (OS)
Will compare the distributions of OS between the two treatment arms to determine if patients treated with modified fluorouracil, leucovorin calcium, oxaliplatin, and irinotecan (mFOLFIRINOX) (with or without nivolumab) have an OS benefit compared to those treated with fluorouracil, leucovorin, and oxaliplatin (FOLFOX) (with or without nivolumab). Kaplan-Meier methodology will be used to estimate the distributions for the treatment arms. To compare the OS distributions between the two treatment arms, we will use a one-sided logrank test to evaluate if mFOLFIRINOX (with or without nivolumab) is superior to mFOLFOX (with or without nivolumab) based on an intention to treat analysis. The hazard ratio, median OS, and estimated OS rates at 1 and 2 years will be estimated along with corresponding 95% confidence intervals. Multivariable Cox proportional hazards models will also be used to assess the impact of treatment arm on OS when stratifying on the stratification factors.
Time frame: Up to 2 years from the time of randomization.
Progression-free survival (PFS)
PFS will be evaluated as a time to event outcome and compared in a secondary manner between the two treatment arms. Patients who are alive and progression-free at their last evaluation will be censored at that time point.
Time frame: The time from registration to the time of documented progression and/or death, assessed up to 3 years
Overall response rate
The best response achieved after initiation of therapy on protocol will also be assessed based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria and will be summarized by treatment arm. The overall response rate will be calculated as the number of patients who achieve a response (partial response, complete response) divided by the total number of patients randomized to the corresponding treatment arm.
Time frame: Up to 3 years
Duration of Response
Time frame: The time between each patient's best tumor response and progression (or date of last disease assessment for patients who die without progression or are lost to follow-up), assessed up to 3 years
Incidence of adverse events
The toxicity and tolerability of each of these regimens will be evaluated and captured using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version (v.) 5, where the type and severity grade of each adverse event will be collected and tabulated within each of the treatment arms. Perceived attribution to study treatment will also be captured. Tolerability will further be assessed by summarizing the numbers of patients who require dose modifications or delays, and reasons for patients to go off treatment.
Time frame: Up to 3 years
Patient reported outcomes
Patient-reported side effect assessments (Patient Reported Outcomes \[PRO\]-CTCAE) will also be collected before and during therapy and will be summarized within and compared between treatment arms. To evaluate between-arm differences in patient-reported symptomatic adverse events as assessed by the PRO-CTCAE, the frequency and proportion of patients with a maximum post-baseline score greater than 0 will be compared across arms using a chi\^2 test or Fisher's exact test with a nominal significance level of alpha = 0.10. Similarly, the frequency and proportion of patients with a maximum post-baseline score greater than or equal to 3 will be compared across arms using a chi\^2 test or Fisher's exact test with a nominal significance level of alpha = 0.10.
Time frame: At baseline, day 1 of cycles 1-8 and day 1 of each odd-numbered cycle thereafter
Exploratory correlative markers
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 and cell free deoxyribonucleic acid during the treatment.
Time frame: Up to 3 years
Incidence of adverse events
Will evaluate the delinquency rate for the standard adverse event (AE) case report forms (CRFs) for this trial over the course of the trial and compare this to the proportion of patients with delinquent AE CRFs on other phase III trials conducted during the same time frame as this trial.
Time frame: up to 3 years
Feasibility and compliance of intervention
Finally, we will also collect data related feasibility and compliance in term of the number of queries received by participating sites regarding questions on attribution collection as well as if any attribution is forcibly submitted using the comments fields.
Time frame: Up to 3 years
