Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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)

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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
* 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).
