  18 and up

Participation Criteria

Inclusion Criteria:

1. Be 18 years or older.
2. Be male or non-pregnant females who agree to comply with applicable contraceptive requirements of the protocol (see Table 12. Acceptable Contraceptive Methods.)
3. Histologically and/or cytologically confirmed gastrointestinal tumours that are metastatic or unresectable, and are subject to receive FOLFOX as SOC per investigator's judgement. Participants will have received at least one line of chemotherapy in the metastatic setting. Colorectal cancer: Patients must have received at least 1 prior line of therapy prior to enrollment in this study. Pancreatic cancer: Patients must have received at least 1 prior line of therapy. Gastric cancer: Patients who have not received prior treatment may be included in this study. GEJ (gastroesophageal junction) cancer patients are considered eligible to enter this trial. Cholangiocarcinoma: locally advanced or metastatic biliary tract cancer (intra or extrahepatic cholangiocarcinoma or gallbladder cancer) are eligible to enter this trial. Patients must have received at least 1 prior line of therapy (with gemcitabine-based chemotherapy). Colorectal cancer (ARM VI): Patients must have received at least 2 prior lines of therapy prior to enrollment in this study, one of which was a 5-FU based regimen. Colorectal cancer (ARM VII): Patients must have received only 1 prior line of therapy in the metastatic setting but remain naïve to oxaliplatin prior to enrollment in this study.
4. Have measurable disease according to RECIST v1.1 (at least one measurable lesion).
5. Have an anticipated survival of at least 16 weeks.
6. Be ambulatory, with an Eastern Cooperative Oncology Group (ECOG) performance score of 0 or 1.
7. Have adequate organ function, defined as:

1. Hematologic: ANC ≥ 1.5 x 109/L, Hgb ≥ 9.0 g/dL and platelet count ≥ 100 x 109/L
2. Hepatic: total bilirubin ≤ 1.5 x ULN (or ≤ 3 x ULN for subjects with Gilbert's Syndrome); transaminases ≤ 2.5 x ULN (may be up to ≤ 5x ULN if clearly due to liver metastases) and ALP ≤ 2.5 x ULN (or ≤ 3 x ULN if liver metastases).
3. Renal: serum creatinine ≤ 1.5 x ULN or creatinine clearance ≥ 50 mL/min.

c. Urine protein is 0, trace, or +1 on dipstick urinalysis, or \< 1.0 gram on 24-hour urine protein analysis
8. Be on stable doses of any drugs that may affect hepatic drug metabolism or renal drug excretion (e.g., non-steroidal anti-inflammatory drugs, corticosteroids, barbiturates, diphenylhydantoin, narcotic analgesics, probenecid). Such drugs should not be initiated while the subject is participating in this study or have been initiated within 30 days beforehand before the start of treatment. Whenever possible, narcotic analgesic doses should be stable within 30 days prior to study entry and during the first cycle of therapy.
9. Resolved acute effects of any prior therapy before the start of treatment to baseline severity or grade ≤1 CTCAE 5.0 except for adverse events not constituting a safety risk by investigator judgment (such as alopecia)
10. Able to take oral medications (for pre-medications and supportive management)
11. Understand and be able, willing, and likely to fully comply with study procedures and restrictions.
12. Be fully informed about their illness and the investigational nature of the study protocol, and sign a REB-approved Informed Consent Form (ICF).
13. (ARM VII): BRAF wild-type tumour status

Exclusion Criteria:

1. Neuropathy \> grade 2
2. Previous intolerance to or significant reaction secondary to fluorouracil or oxaliplatin
3. Cerebrovascular accident within the past 6 months before the start of treatment.
4. History or presence of central nervous system (CNS) metastasis or leptomeningeal tumours as documented by CT or MRI scan, analysis of cerebrospinal fluid or neurological exam.
5. Any serious medical conditions that might be aggravated by treatment or limit compliance. This includes, but is not limited to uncontrolled psychiatric disorders, serious infections, active peptic ulcer disease and bleeding diathesis
6. Any history of serious cardiac illness including (but not confined to):

* Previous or active myocardial infarction \< 6 months before the start of treatment

* Uncontrolled hypertension (systolic ≥ 140 mmHg or diastolic ≥ 90 mmHg)
* Ventricular arrhythmia \< 6 months before the start of treatment
* Left ventricular ejection fraction (LVEF) \< 50% as measured either by radionuclide angiography or echocardiogram
* QTc interval \> 470 msec
7. Hemoptysis, cerebral, or clinically significant gastrointestinal hemorrhage in the past 6 months before the start of treatment
8. Any other known malignancy within 3 years before the start of treatment (with the exception of non-melanoma skin cancer that had undergone curative treatment, cervical cancer in situ, or ductal/lobular carcinoma in situ of the breast that has underwent local treatment
9. Active gastrointestinal tract disease with malabsorption syndrome.
10. Non-healing wound, fracture, or ulcer, or presence of symptomatic peripheral vascular disease.
