• Mean resting corrected QT interval (QTc) >470 msec, obtained from 3 ECGs
• Any clinically important abnormalities in rhythm, conduction, or morphology of resting ECG
• Patient with any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalaemia, congenital long QT syndrome, family history of long QT syndrome, or unexplained sudden death under 40 years of age in first-degree relatives or any concomitant medication known to prolong the QT interval and cause Torsades de Pointes
6. Inadequate bone marrow reserve or organ function
7. History of other malignancies, except: adequately treated non-melanoma skin cancer or lentigo maligna , curatively treated in-situ cancer, or other solid tumors curatively treated with no evidence of disease for > 5 years following the end of treatment and which, in the opinion of the treating physician, do not have a substantial risk of recurrence of the prior malignancy.
