Stenting for bile duct obstruction and need for pain medications are allowed provided all other inclusion criteria are met Prior malignancy except for the following: adequately treated basal or squamous cell skin cancer, in situ cervical cancer, adequately treated cancer from which the patient has been disease-free for at least 3 years prior to screening Unwilling or unable to avoid the concomitant use of strong CYP3A4 inducers or inhibitors during treatment with irinotecan A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval > 480 milliseconds (ms) (CTCAE grade 1) using Fredericia's QT correction formula (i.e. QTcF) A history of additional risk factors for TdP (e.g., heart failure, hypokalemia, family history of long QT syndrome) The use of concomitant medications that prolong the QT/QTc intervals Contraindications to any of the FFX treatment as follows: Folinic Acid Calcium Folinate is contraindicated in patients who have previously shown hypersensitivity to folinate or any of the excipients. Calcium Folinate Injection is contraindicated in the treatment of pernicious anemia or other megaloblastic anemias where vitamin B12 is deficient. Its use can lead to an apparent response of the hematopoietic system, but neurological damage may occur or progress if already present. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take calcium folinate tablets. Fluorouracil/5FU Fluorouracil is contraindicated in patients who have any known hypersensitivity to fluorouracil, are seriously debilitated or are suffering from bone marrow depression after radiotherapy or treatment with other antineoplastic agents, or who are suffering from a potentially serious infection. Fluorouracil is strictly contraindicated in pregnant or breast-feeding women. Flourouracil should not be used in the management of non-malignant disease. Fluorouracil must not be taken or used concomitantly with brivudin, sorivudine and analogues. Brivudin, sorivudine and analogues are potent inhibitors of the enzyme dihydropyrimidine dehydrogenase (DPD) which degrades fluorouracil In patients with known complete absence of dihydropyrimidine dehydrogenase (DPD) activity Oxaliplatin Oxaliplatin is contraindicated in patients who have a known history of hypersensitivity to oxaliplatin or to any of the excipients are breast-feeding. have myelosuppression prior to starting first course, as evidenced by baseline neutrophils <2x109/l and/or platelet count of <100x109l. have a peripheral sensitive neuropathy with functional impairment prior to first course. have a severely impaired renal function (creatinine clearance less than 30 ml /min) Irinotecan Chronic inflammatory bowel disease and/or bowel obstruction History of severe hypersensitivity reactions to Irinotecan hydrochloride trihydrate or to any of the excipients Bilirubin > 3 times the ULN Severe bone marrow failure. WHO performance status > 2. Concomitant use with St John's wort

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Survival (OS) | Defined as the duration from the date of randomization to the date of death from any cause | 38 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression Free Survival (PFS) | Defined as the duration from the date of randomization to the date of progressive disease or death from any cause. Progressive Disease is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), as at least 20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must have also demonstrated an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression. | 38 months | 
| Overall Response Rate (ORR) | Defined as the rate of Complete Response (CR) plus Partial Response (PR): Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), at least 30% decrease in the sum of diameters of target lesions; | 38 months |
