> 5.0 × ULN for patients with liver metastases
Total bilirubin > 1.5 × ULN
Serum creatinine > 1.5 × ULN

Absolute neutrophil count (ANC) < 1.5 × 10^9/L
Platelet count < 100 × 10^9/L
Haemoglobin < 90 g/L
Persistent (> 4 weeks) severe pancytopenia due to previous therapy rather than to disease (ANC < 0.5 × 10^9/L or platelets < 50 x 10^9/L)
Cardiac dysfunction (defined as myocardial infarction within 6 months of study entry, New York Heart Association Class II/III/IV heart failure, unstable angina, unstable cardiac arrhythmias, or left ventricular ejection fraction < 55 percent)
Mean resting QT interval corrected for heart rate by the Fridericia formula (QTcF) > 470 msec obtained from 3 electrocardiograms (ECGs) obtained within 5 minutes of each other prior to the first dose
Any clinically important abnormalities in rhythm, conduction, or morphology on resting ECG (e.g., complete left bundle branch block, third degree heart block). Controlled atrial fibrillation (AF) is permitted
Any factor that increases the risk of QTc prolongation or of arrhythmic events (e.g., heart failure, hypokalaemia, congenital long QT syndrome, immediate family history of long QT syndrome or unexplained sudden death under 40 years of age)
