Inclusion criteria
1. Signed informed consent (IC) obtained before any study specific procedures. Subjects must be able to understand and willing to sign a written informed consent. 2. Male or female subjects 18 years of age. 3. Life expectancy of at least 3 months. 4. Histological or cytological documentation of adenocarcinoma of the colon or rectum. All other histological types are excluded. 5. Measurable metastatic stage IV disease with at least 1 measurable metastatic lesion following RECIST criteria v 1.1. 6. Subjects with metastatic colorectal cancer (Stage IV). 7. Progression during or within 3 months following the last administration of approved standard therapies which must include fluoropyrimidine, oxaliplatin, irinotecan, an anti-VEGF and an anti-EGFR (if RAS WT) 8. Subjects treated with oxaliplatin in an adjuvant setting should have progressed during or within 6 months of completion of adjuvant therapy 9. Subjects who progress more than 6 months after completion of oxaliplatin containing adjuvant treatment must be retreated with oxaliplatin-based therapy to be eligible. Subjects who have withdrawn from standard treatment due to unacceptable toxicity warranting discontinuation of treatment and precluding retreatment with the same agent prior to progression of disease will also be allowed into the study 10. ECOG Performance Status of 0 or 1(within 14 days prior to the initiation of study treatment) 11. Adequate bone marrow, liver and renal function as assessed by the following laboratory requirements: * Total bilirubin =1.5 x the upper limit of normal (ULN). * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) = 2.5 x ULN (5 x ULN for subjects with liver involvement of their cancer). * Alkaline phosphatase limit = 2.5 x ULN (5 x ULN for subjects with liver and/or bone involvement of their cancer). * Lipase = 1.5 x the ULN. * Serum creatinine 1.5 x the ULN or = 30 mL/min as calculated using the Cockcroft-Gault equation. * Platelet count \>100000/mm3, hemoglobin \>9 g/dL, absolute neutrophil count (ANC) \>1500/mm3. * International normalized ratio (INR)/ Partial thromboplastin time (PTT) 1.5 x ULN. (Subjects who are therapeutically treated with an agent such as warfarin or heparin will be allowed to participate provided that no prior evidence of underlying abnormality in coagulation parameters exists. Close monitoring of at least weekly evaluations will be performed until INR/PTT is stable based on a measurement that is pre-dose as defined by the local standard. * Blood transfusion to meet the inclusion criteria will not be allowed. 12. Women of childbearing potential and men must agree to use adequate contraception before entering the program until at least 8 weeks after the last study drug administration. The investigator or a designated associate is requested to advise the subject on how to achieve an adequate birth control. Adequate contraception is defined in the study as any medically recommended method (or combination of methods) as per standard of care. Women of childbearing potential must have a blood or urine pregnancy test performed a maximum of 7 days before start of study treatment, and a negative result must be documented before start of study treatment.

Congestive heart failure = New York Heart Association (NYHA) class 2. 5. Unstable angina (angina symptoms at rest), new-onset angina (begun within the last 3 months). 6. Myocardial infarction less than 6 months before start of study drug. 7. Cardiac arrhythmias requiring anti-arrhythmic therapy (beta blockers or digoxin are permitted). 8. Uncontrolled hypertension. (Systolic blood pressure \> 140 mmHg or diastolic pressure \>90 mmHg despite optimal medical management). 9. Arterial or venous thromboembolism within 6 months prior to randomization. 10.

Any hemorrhage or bleeding event = CTCAE Grade 3 within 4 weeks prior to the start of study medication. 18. Non-healing wound, ulcer, or bone fracture. 19. Renal failure requiring hemo-or peritoneal dialysis. 20. Dehydration CTCAE v. 4.0 Grade = 1. 21. Substance abuse, medical, psychological or social conditions that may interfere with the subject's participation in the study or evaluation of the study results. 22. Known hypersensitivity to any of the study drugs, study drug classes, or excipients in the formulation. 23. Any illness or medical conditions that are unstable or could jeopardize the safety of the subject and his/her compliance in the study. 24. Interstitial lung disease with ongoing signs and symptoms 25. Persistent proteinuria of CTCAE Grade 3 (\>3.5g/24 hours). 26. Subjects unable to swallow oral medications. 27.

Unresolved toxicity higher than CTCAE (v. 4.0) \> Grade 1 attributed to any prior therapy/procedure excluding alopecia, hypothyroidism and oxaliplatin induced neurotoxicity \> Grade 2. 29. Subjects treated with strong CYP3A4 inhibitors or inducers (refer to appendix 8 and to section 6.3.8. Prohibited concomitant medication). 30. Subjects receiving G-CSF within 3 weeks prior to signing the ICF 31. Concomitant participation or participation within the last 30 days in another clinical trial 32.
