• Activated partial thromboplastin time (aPTT) =< 1.5 x ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants (within 7 days prior to protocol therapy)
• Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
• Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year
• Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
• Willingness to undergo intraperitoneal port placement

Exclusion Criteria

• Has gastric cancer involving the distal esophagus above the gastroesophageal (GE) junction (Siewert 1, proximally), or second portion of the duodenum (distally)
• Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment
• Has a tumor positive for HER2 staining
• Has had prior surgery with dense intra-abdominal adhesions
• Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment
• Has had a prior monoclonal antibody within 4 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier
• Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent
• Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy
• Has known central nervous system (CNS) metastases and/or carcinomatous meningitis
• Has an active infection requiring antibiotic therapy
• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject’s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator
• Has any other medical condition, including mental illness or substance abuse, deemed by the Investigator to be likely to interfere with a patient’s ability to sign informed consent, cooperate and participate in the study, or interfere with the interpretation of the results
• Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment
• Has a known history of human immunodeficiency virus (HIV) (HIV 1/2 antibodies)
• Has known active hepatitis B (e.g., hepatitis B surface antigen [HBsAg] reactive) or hepatitis C (e.g., hepatitis C virus [HCV] ribonucleic acid [RNA] [qualitative] is detected)
• Patients receiving any medications or substances that are inhibitors or inducers of CYP 3A4 are ineligible. Investigator can change to a similar agent that is a non-CYP3A4 inhibitor/inducer with a washout period of 1 week
• Patients with known hypersensitivity to any of the components of docetaxel or mFOLFOX6
• Patients who received pelvic or abdominal radiotherapy
• Peripheral neuropathy >= grade 2
• History of allogeneic transplant
• Any known cardiac abnormalities, in accordance with mFOLFOX6 guidelines, such as: * Congenital long QT syndrome * Corrected QT (QTc) interval >= 485 milliseconds * Myocardial infarction within 6 months of cycle 1, day 1 (C1D1). Subjects with a history of myocardial infarction between 6 and 12 months prior to C1D1 who are asymptomatic and have had a negative cardiac risk assessment (treadmill stress test, nuclear medicine stress test, or stress echocardiogram) since the event may participate * Other significant electrocardiogram (ECG) abnormalities including 2nd degree atrio-ventricular (AV) block type II, 3rd degree AV block, or bradycardia (ventricular rate less than 50 beats/min) trial treatments * Symptomatic coronary artery disease (CAD), e.g., angina. In any patient in whom there is doubt, the patient should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present * An ECG recorded at screening showing evidence of cardiac ischemia (ST depression, depression of >= 2 mm, measured from isoelectric line to the ST segment). If in any doubt, the patient should have a stress imaging study and, if abnormal, angiography to define whether or not CAD is present * Congestive heart failure (CHF) that meets New York Heart Association (NYHA) class II to IV definitions and/or ejection fraction < 40% by multigated acquisition scan (MUGA) scan or < 50% by echocardiogram and/or magnetic resonance imaging (MRI) * A known history of sustained ventricular tachycardia (VT), ventricular fibrillation (VF), Torsade de Pointes, or cardiac arrest unless currently addressed with an automatic implantable cardioverter defibrillator (AICD) * Hypertrophic cardiomegaly or restrictive cardiomyopathy from prior treatment or other causes * Uncontrolled hypertension, i.e., blood pressure (BP) of >= 160/95; patients who have a history of hypertension controlled by medication must be on a stable dose (for at least one month) and meet all other inclusion criteria; or * Any cardiac arrhythmia requiring an anti-arrhythmic medication (excluding stable doses of beta-blockers) * Patients taking drugs leading to significant QT prolongation * Evidence/history of coronary vasospasm
• Any other condition that would render the patient to be unfit for the trial as deemed by the principal investigator (PI) or clinical team
