Inclusion Criteria: 1. Patients must have provided informed consent before performing any study specific procedures. 2. Histological or cytological documented adenocarcinoma of the colon or rectum. 3. Patients with metastatic colorectal cancer (stage IV). 4. Measurable disease, defined as at least one unidimensional measurable lesion on a computed tomography (CT) scan according to RECIST v1.1. 5. The patient must have progressed following exposure of all the following agents : one fluoropyrimidine-based chemotherapy (capecitabine or fluorouracil \[5-FU\], combined with oxaliplatin and/or irinotecan (including FOLFOX, FOLFIRI or FOLFOXIRI) as well as EGFR and/or VEGF inhibitors in patients eligible for these treatments. 6. Patients considered eligible for treatment with both regorafenib and trifluridine-tipiracil. 7. Male or female patients aged ≥18 years. 8. ECOG performance status of ≤1. 9. Adequate bone marrow, liver and renal functions as assessed by the following laboratory requirements: * Total bilirubin ≤1.5 x upper limit of normal (ULN). * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 x ULN (≤5 x ULN for patients with liver metastasis). * Alkaline phosphatase limit ≤2.5 x ULN (≤5 x ULN for patients with liver metastasis). * Serum creatinine ≤1.5 x ULN. * International normalized ratio (INR) and partial thromboplastin time (PTT) ≤1.5 x ULN. Patients receiving anticoagulants, such as warfarin or heparin are eligible if there is no prior evidence of an underlying abnormality with coagulation. * Platelet count ≥75000 /mm³, hemoglobin (Hb) ≥9 g/dL, absolute neutrophil count (ANC) ≥1500/mm³. Blood transfusions to meet this inclusion criterion are not allowed. 10. Women of childbearing potential and men must agree to use a highly effective contraception (1% failure rate) from the signing of the informed consent form until at least 6 months after the last study drug administration. Women using hormonal contraceptive must also use a barrier method. 11. Women of childbearing potential must have a negative pregnancy test within 7 days before starting study treatment. 12. Patients affiliated to the social security system. 13. Patient willing and able to comply with the protocol for the duration of the study including treatment, scheduled visits, and examinations throughout the study, including follow up. Exclusion Criteria: 1. Patients with symptomatic brain or meningeal metastasis, unless definitive therapy occurred more than 6 months ago and with a confirmation of tumoral control within 4 weeks of starting study treatment. 2. Previous or concurrent cancer that is distinct in primary site or histology from colorectal cancer within 5 years prior to study inclusion, except for curatively treated in situ cervical cancer, non-melanoma skin cancer, and superficial bladder tumors: staged Ta (non-invasive tumor), Tis (carcinoma in situ), and T1 (tumor with lamina propria invasion). 3. Prior treatment with regorafenib or any other tyrosine kinase inhibitor. 4. Prior treatment with trifluridine/tipiracil. 5. Known hypersensitivity to any of the study drugs, study drug classes, or study drug excipients. 6. Unresolved toxicity grade \>1 (by CTCAE v5.0) caused by prior therapy/procedure, excluding alopecia, hypothyroidism, and oxaliplatin-induced neurotoxicity grade ≤2. 7. Patient with moderate or severe hepatic impairment (Child-Pugh C). 8. Known UGT1A1 polymorphisms. History of Gilbert's syndrome. 9. Major surgical procedure, open biopsy, or significant traumatic injury within 28 days before starting study treatment. 10. Chemotherapy within 21 days of starting study treatment. 11. Radiotherapy within 4 weeks of starting study treatment, except for palliative radiotherapy within 2 weeks. 12. Active cardiac disease including any of the Following: * Congestive heart Failure: New York Heart Association (NYHA) class ≥2. * Unstable angina (angina symptoms at rest), or a new-onset angina (within the 3 months before enrolment). * Myocardial infarction that occurred less than 6 months before enrolment. * Cardiac arrhythmias requiring anti-arrhythmic therapy (treatment with beta blockers or digoxin are permitted) * Uncontrolled hypertension (systolic blood pressure \>140 mmHg or diastolic pressure \>90 mmHg despite treatment). 13. Arterial or venous thrombotic or embolic events such as cerebrovascular accident (including transient ischemic attacks), deep vein thrombosis, or pulmonary embolism within 6 months of starting study treatment. 14. Ongoing infection grade 2 (CTCAE v5.0). 15. Known history of human immunodeficiency virus (HIV) infection. 16. Active hepatitis B or C, or chronic hepatitis B or C requiring treatment with antiviral therapy. 17. Patients with seizure disorder requiring medication. 18. Patients with a history of any bleeding diathesis, irrespective of the severity. 19. Any hemorrhage or bleeding event grade ≥3 (CTCAE v5.0) within 4 weeks before starting study treatment. 20. Presence of a wound, ulcer, or bone fracture that is not healing. 21. Patients unable to swallow oral medications. 22. Bowel malabsorption or extended bowel resection that could affect the absorption of regorafenib, occlusive syndrome. 23. Presence of gastro-intestinal fistula or perforation. 24. Any illness or medical conditions that are unstable or could jeopardize the safety of the patient and their compliance in the study. 25. Patients participating in another therapeutic study within the 30 days before enrolment. 26. Pregnant or breast feeding women. 27. Person deprived of their liberty or under protective custody or guardianship.
