Brief summary: The purpose of the study is to evaluate the performance of various tumor response criteria (Choi and RECIST1.1 criteria) in the assessment of regorafenib activity.

Moreover, an assessment of the tumor heterogeneity will be made using computed tomographic texture analysis (CTTA)

Detailed description: This is a phase II study in patients with metastatic colorectal cancer treated by regorafenib.

Eligibility criteria: Inclusion Criteria:

1. Signed and dated informed consent.
2. Patients with histologically proven metastatic colorectal cancer
3. Patients previously treated with, or who are not considered candidates for available therapies, i.e., fluoropyrimidine-based chemotherapy, anti-VEGF therapy and anti-EGFR therapy (if patients were RAS wild-type).
4. ECOG PS = 0 or 1
5. Aged 18-years or older
6. Life expectancy of at least 3 months
7. Adequate renal, bone marrow, liver and pancreatic functions:

   * Estimated creatinine clearance ≥ 30 mL/min as calculated using the Cockcroft-Gault equation
   * Platelet count ≥ 100.000/mm3; hemoglobin ≥ 9 g/dL; absolute neutrophil count ≥ 1500/mm3. Transfusion to meet the inclusion criteria will not be allowed
   * Total bilirubin ≤ 1.5 the upper limit of normal value (ULN); alanine aminotransferase (ALAT) and aspartame aminotransferase (ASAT) ≤ 3.0 x ULN (≤ 5.0 x ULN for patients with liver involvement of their cancer); alkaline phosphatase (ALP) ≤ 2.5 x ULN (≤ 5.0 x ULN for patients with liver involvement of their cancer and/or have bone metastases)
8. International normalized ratio (INR) ≤ 1.5 x ULN and partial thromboplastin time (PTT) or activated partial thromboplastin time (aPTT) ≤ 1.5 x ULN unless receiving treatment with therapeutic anticoagulation. Patients being treated with anticoagulant, e.g., heparin, will be allowed to participate provided no prior evidence of an underlying abnormality in these parameters exists. Close monitoring of at least weekly evaluation will be performed until INR and PTT are stable based on a pre-dose measurement as defined by the local standard of care
9. At least one target lesion on CT scan
10. No contraindication to Iodine contrast media injection during CT.
11. For women of childbearing potential, blood or urine pregnancy test performed a maximum of 7 days before start of study treatment and negative result documented before start of study treatment
12. When applicable, i.e., women of childbearing potential having sexual activity, men having sexual activity, must agree to use an adequate contraception before entering the study, until at least 8 weeks after the last study drug administration
13. Registration in a national health care system (CMU included).

Exclusion Criteria:

1. Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before inclusion in the trial ; planned surgical procedure within the first month of treatment or any procedure that might change the timing of regorafenib administration during the first month of treatment
2. Patients under judicial protection (curatorship, tutorship) and/or deprived of freedom
3. Major surgical procedure, open biopsy or significant traumatic injury within 28 days before start of study medication
4. Pregnancy or breastfeeding

11. Pleural effusion or ascites that causes respiratory compromise (≥ CTCAE grade 2, NCI-CTCAE v 4.0 dyspnea)
12. Ongoing infection \>grade 2, NCI- CTCAE v 4.0

14. Known history of human immunodeficiency virus (HIV) infection
15. Active hepatitis B or C or chronic hepatitis B or C requiring treatment with antiviral therapy
16. Patients with seizure disorder requiring medication
17. History of organ allograft
18. Patients with evidence or history of any bleeding diathesis, irrespective of severity

20. Non-healing wound, non-healing ulcer or non-healing bone fracture
21. Dehydration grade ≥1, NCI-CTCAE v 4.0
22. Known hypersensitivity to the study drug, study drug classes or excipient in the formulation
23. Interstitial lung disease with ongoing signs or symptoms at the time of inclusion
24. Persistent proteinuria \>3.5 g/24 hour measured by urine protein-creatinine ratio from a random urine sample (≥ Grade 3, NCI-CTCAE v 4.0)
25. Patients unable to swallow oral medication
26. Any malabsorption condition
27. Unresolved toxicity higher than Grade 1, NCI-CTCAE v 4.0, attributed to any prior therapy/procedure excluding alopecia and oxaliplatin induced neuropathy
28. Systemic anticancer therapy including cytotoxic therapy, signal transduction inhibitors, immunotherapy, and hormonal therapy during this trial or within 3 weeks
29. Treatment with any other investigational medicinal product within 28 days prior to study entry
30. Chronic treatment potentially interacting with the study medication, i.e. strong CYP3A4 inducers/inhibitors, strong UGT1A9 inhibitors
