• For non operated patients recurrent disease must be at least one bi-dimensionally measurable contrast-enhancing lesion with clearly de-fined margins by MRI scan, with minimal diameters of 10 mm, visible on 2 or more axial slices 5 mm apart, based on MRI scan done within two weeks prior to study inclusion.
• Patients who require anti-convulsant therapy must be taking non-enzyme inducing antiepileptic drugs (non-EIAED). Patients previously on EIAED must be switched to non-EIAED and stable at least 2 weeks prior to study inclusion and be stable on a constant dose.

• No core biopsy or other minor surgical procedure within 7 days prior to randomization. Placement of a central vascular access device (CVAD) if performed at least 5 days prior to study treatment administration is allowed.
• Before patient study inclusion and study related procedures (that would not have been performed as part as standard care), written in-formed consent must be given according to ICH/GCP, and nation-al/local regulations.
• Subjects with the ability to follow study instructions and likely to attend and complete all required visits

Exclusion Criteria:

General Exclusion Criteria:

• Subjects not able to give consent

• Simultaneously participation in another clinical trial or participation in any clinical trial involving administration of an investigational medicinal product within 30 days prior to clinical trial beginning
• Subjects with a physical or psychiatric condition which at the investigator's discretion may put the subject at risk, may confound the trial results, or may interfere with the subject's participation in this clinical trial
• Known or persistent abuse of medication, drugs or alcohol

Indication specific exclusion criteria:

• Evidence of current/active intratumor hemorrhage by MRI
• More than two relapses
• Elongation of corrected QT-time (QTc) > 450 ms (male patients) and ≥ 460 ms (female patients), respectively
• Patients with any clinically significant medical or surgical condition which, according to investigators´ discretion, should preclude participation - i.e. severe renal disease, severe pancreatic disease, active or uncontrolled infection, uncontrolled diabetes, active or chronic liver disease (cirrhosis, chronic active hepatitis or chronic persistent hepatitis) - hepatitis B or C virus carriers with normal liver function tests, can be included.

• Patients with impaired cardiac function or clinically significant cardiac diseases, including any of the following:

  • History or presence of serious uncontrolled ventricular arrhythmi-as
  • Bradycardia (<60/min): i) Clinically significant resting bradycardia (=> 40/min) with syncopes or chronotropic incompetence or ii) asymptomatic bradycardia with a heart rate < 40/min and/or paus-es in ventricular rate > 3 s
  • LVEF assessed by 2-D echocardiogram (ECHO) < 50% or lower limit of normal (which ever is higher)

• Any of the following within 6 months prior to starting TKI258:

  • Myocardial infarction (MI),
  • severe/unstable angina,

  • Congestive Heart Failure (CHF),
  • Cerebrovascular Accident (CVA),
  • Transient Ischemic Attack (TIA)
• Uncontrolled hypertension defined by a SBP ≥ 160 mm Hg and/or DBP ≥ 100 mm Hg, with or without anti-hypertensive medication. Initiation or adjustment of antihypertensive medication(s) is allowed prior to starting Dovitinib (TKI258)
• Patients with impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of TKI258 (e.g. severe ulcer-ative diseases, uncontrolled nausea, vomiting, diarrhea, malabsorption syndrome, or extensive (>1m) small bowel resection, inability to swal-low oral medications). Prior partial gastrectomy is not an exclusion cri-terion.
• Patients with prior complete gastrectomy
• Inadequate bone marrow reserve as demonstrated by an absolute neutrophil count ≤1.5 x 109 /L or platelet count ≤ 100 x 109 /L or re-quiring regular blood transfusions to maintain haemoglobin > 9g/dL
