Inclusion Criteria:

1. Patients are 18 years of age or older
2. Patients are female or male.

7. Estimated life expectancy of at least 3 months
8. Have ECOG performance status score 0-2
9. Have received at least one any prior treatment for local recurrence or metastatic disease and have relapsed.
10. Signed and dated written informed consent prior to admission to the study
11. If Patients have been treated with anti-VEGF agents, such as Bevacizumab, last dose must be \>/= 4 weeks.
12. Have tissues from a biopsy, or have up to 20 unstained slides available from archived metastatic tissue block for biomarker evaluation
13. Patients are able to swallow and retain oral medication

4. Uncontrolled hypertension defined by an SBP\>150 and/or a DBP\>100 mm Hg with or without anti-hypertensive medication
5. History of gastrointestinal disorders (medical disorders or extensive surgery) which may interfere with the absorption of the study drug as determined by the investigator.
6. Patients have a concurrent disease or condition that would make them inappropriate for study participation, or any serious medical disorder that would interfere with patients' safety as determined by the investigator.
7. Patients with only locally or regionally confined disease without evidence of metastatic disease
8. Prior treatment with BIBF 1120 or any other VEGFR inhibitor within 4 weeks
9. Known hypersensitivity to the trial drugs , to their excipients or to contrast media
10. Chemotherapy, hormonal therapy, radiotherapy (except for brain and extremities) or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 4 weeks prior to treatment with the trial drug
11. Persistence of toxicity from previous chemo and/or radiotherapy \> grade 2.
12. Active brain metastases (e.g. stable for \<4 weeks, no adequate previous treatment with radiotherapy, symptomatic, requiring treatment with anti-convulsants; dexamethasone therapy will be allowed if administered as stable dose for at least one month before randomisation).
13. Radiographic evidence of cavitary or necrotic tumors
14. Centrally located tumors with radiographic evidence (CT or MRI) of local invasion of major blood vessels
15. Treatment with other investigational drugs or treatment in another clinical trial within the past 4 weeks before start of therapy or concomitantly with the trial
16. Therapeutic anticoagulation( except low-dose heparin and/or heparin flush as needed for maintenance of an in-dwelling intravenous devise) or anti-platelet therapy (except for low-dose therapy with acetylsalicylic acid \< 325mg per day
17. Major injuries within the past 10 days prior to start of study treatment with incomplete wound healing and/or planned surgery during the on-treatment study period
