Exclusion Criteria:

• Brain metastases or spinal cord compression, unless treated at least 4 weeks before entry and stable without steroid treatment for 10 days or greater.
• Last dose of prior chemotherapy must be discontinued at least 4 weeks before the start of study treatment.
• Last dose of radiotherapy received within 4 weeks before the start of study treatment excluding palliative radiotherapy.
• Prior treatment with VEGFR TKIs
• Serum bilirubin . 1.5 x the upper limit of reference range.
• Serum creatinine >1.5 x ULRR or Creatinine clearance (as determined by the Cockcroft - Gault method) less than or equal to 50 mL/min.
• ALT or AST >5 x ULRR
• ALP >5 x ULRR
• Evidence of severe or uncontrolled systemic disease or any concurrent conditions which in the investigators opinion make it undesirable for the patient to participate in the study or would jeopardize compliance with the protocol.
• Any unresolved toxicity greater than CTCAE Grade 2 for previous anti-cancer therapy.
• Significant cardiovascular event within 3 months before entry, or presence of cardiac disease that in the opinion of the investigator increases the risk of ventricular arrhythmia.

• Women who are pregnant or breast feeding.
• Any concomitant medications that may cause QTc prolongation or induce or induce Torsades de Pointes or induce CTP3A4 function.
• Hypotension not controlled by medical therapy.
• Participation in a clinical study of any investigational pharmaceutical agent within 30 days prior to commencing study treatment.
• Major surgery within 4 weeks or incompletely healed surgical incision.
• Previous or current malignancies of other histologies within the last 5 years, with the exception of in situ carcinoma of the cervix and adequately treated basal cell or Squamous cell carcinoma of the skin.
