within the previous 2 years.
4. Major surgery within 4 weeks of start of treatment
5. Clinically significant cardiovascular disease (either active or within 6 months prior

dysrhythmias of NCI CTCAE grade ≥2
6. Any of the following cardiac criteria:
- • Mean resting corrected QT interval (ECG interval measured from the onset of the
QRS complex to the end of the T wave) for heart rate (QTcF) > 470 msec obtained
from 3 ECGs, using the screening clinic ECG machine-derived QTc value
- • Any clinically important abnormalities in rhythm, conduction or morphology of
resting ECG (e.g., complete left bundle branch block, third degree heart block,
second degree heart block, PR interval > 250 msec)
- • Any factors that increase the risk of QTc prolongation or risk of arrhythmic
events such as heart failure, hypokalemia, congenital long QT syndrome, family
history of long QT syndrome, or any concomitant medication known to prolong the

8. Gastrointestinal disease (e.g., Crohn's disease, ulcerative colitis, or short gut
