Eligibility Criteria

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

Inclusion Criteria

1. Signing of the informed consent form.
2. The patient must be able to understand the information and state expressly his or her desire to take part in the study.
3. Age ≥ 18 years.
4. Histologically or cytologically documented adenocarcinoma of the colon or rectum.
5. Patients with metastatic colorectal cancer (stage IV) with any RAS or BRAF mutation.
6. To have received first\_line treatment with bevacizumab in combination with chemotherapy with the three drugs 5FU/leucovorin (LV), irinotecan and oxaliplatin (FOLFOXIRI), and

* have had radiological progression of the disease during the first\_line treatment, or
* have had radiological progression of the disease within a period of ≤ 6 months after the last dose of first-line treatment, or
* have discontinued part or all of the first\_line treatment due to toxicity and have had radiological progression of the disease within a period of ≤ 6 months after the last dose of first-line treatment.

The patient will have to have received at least one cycle of bevacizumab in combination with FOLFOXIRI + bevacizumab as part of the first\_line treatment.

Patients may have received fluoropyrimidine\_based adjuvant treatment with or without oxaliplatin.
7. Existence of at least one measurable unidimensional lesion using CT or MRI based on the Response Evaluation Criteria in Solid Tumors (RECIST) criteria, version 1.1
8. Overall Eastern Cooperative Oncology Group (ECOG) performance ≤1.
9. Patient's commitment to compliance with the oral medication throughout the duration of the study
10. Life expectancy of at least 3 months
11. Adequate bone marrow, renal and hepatic function, defined as:

* Neutrophils ≥ 1500/mm3
* Platelets ≥100,000/mm3
* Haemoglobin ≥ 9,0 g/dL
* Serum Creatinine ≤ 1.5 x LSN
* Bilirubin levels ≤ 1.5 x LSN
* AST and ALT levels ≤ 2.5 x ULN (if liver metastases \< 5 x ULN)

Exclusion Criteria

1. Prior treatment with regorafenib.
2. Assignment prior to treatment during this study. Patients who are permanently withdrawn from participation in the study treatment will not be allowed to return to it.
3. Prior or concurrent presence of another neoplastic disease that is different in terms of tumour site and histology of the colorectal cancer in the 5 years prior to the inclusion of the patient in the study, except in situ cervical cancer, superficial bladder carcinoma \[Ta (non-invasive), Tis (carcinoma in situ) and T1 (tumour invades lamina propria)\] and non-melanoma skin tumours.
4. Presence or history of brain metastases or meningeal tumours.
5. Major surgery, open biopsy or traumatic injury within 28 days prior to the start of patient treatment with the study medication.
6. Extended-field radiotherapy within 4 weeks prior to inclusion or limited-field radiotherapy in the previous 2 weeks. Patients must have recovered from all treatment-related toxicities.
7. Pregnant or breastfeeding women. Women of childbearing age must use adequate contraception. Women of childbearing age must have a negative pregnancy test within 7 days prior to starting with the study medication.
8. Women of childbearing age and men who wish to take part in the study must agree to use adequate contraception from the signing of the informed consent until at least 3 months after stopping the study medication. The investigator or the person designated by him or her will ensure and advise as to the contraceptive methods that should be used.

Appropriate contraceptive methods include abstinence, oral contraceptives, transdermal patches and injections of sustained-release progestin (starting at least 4 weeks before administration of the IMP), double-barrier method: condom or female condom (diaphragm or cervical/vaginal condom) plus spermicide, intrauterine device (IUD), intrauterine system, implant or vaginal ring (in place at least 4 weeks before administration of the IMP) or male partner sterilisation (vasectomy with documentation of azoospermia) prior to inclusion of the woman in the trial if he is the woman's only sexual partner.

26. Known hypersensitivity to regorafenib or any of its excipients.
27. Presence of any disease or medical condition that might interfere with patient safety or may compromise treatment compliance with it.
