6. Eastern Cooperative Oncology Group (ECOG) performance status 0-1
7. Ability to take medications orally

8. Adequate blood count, liver-enzymes, and renal function:

   • Absolute neutrophil count (ANC) > 1,500 cells/μL without the use of hematopoietic growth factors; and Platelet count ≥ 100 x 109/L (>100,000 per mm3) and Hemoglobin > 9 g/dL (blood transfusions are permitted for patients with hemoglobin levels below 9 g/dL)
   • Serum total bilirubin ≤ 1.5x upper normal limit (ULN) (biliary drainage is allowed for biliary obstruction; elevated bilirubin should be caused by obstruction not impaired liver function as assessed by albumin and international normalised ratio (INR) values):
   • Albumin levels ≥ 3.0 g/dL
   • Patients not receiving therapeutic anticoagulation must have an INR< 1.5 ULN and partial thromboplastin time (PTT) < 1.5 ULN within 7 days prior to inclusion. The use of full dose anticoagulants is allowed as long as the INR or PTT is within therapeutic limits (according to the medical standard in the institution) and the patient has been on a stable dose for anticoagulants for at least three weeks at the time of inclusion.

9. In case of liver cirrhosis: Child-Pugh A
10. Women of childbearing potential must have a negative pregnancy test and must agree to adequate birth control if conception is possible. Males must agree to adequate birth control

Exclusion Criteria:

5. Clinically significant gastrointestinal disorders including bleeding, inflammation, occlusion, or diarrhea > grade 1
6. Any condition or comorbidity that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results

13. Patients who have been incarcerated or involuntarily institutionalized by court order or by the authorities § 40 Abs. 1 S. 3 Nr. 4 AMG.
14. Patients who are unable to consent because they do not understand the nature, significance and implications of the clinical trial and therefore cannot form a rational intention in the light of the facts [§ 40 Abs. 1 S. 3 Nr. 3a German drug law (AMG)].
