• QTcF at screening > 450 msec
• History of syncope or family history of idiopathic sudden death
• Sustained or clinically significant cardiac arrhythmias

• Family history of long QT syndrome
• Concomitant medications known to prolong the QT interval.
• Potassium < or = 3.5 mmol/L
13. Patients who have any severe and/or uncontrolled medical conditions or other conditions that could affect their participation in the study such as:
• Uncontrolled diabetes as defined by HbA1c > 8% despite adequate therapy,
• Patients with the presence of active or suspected acute or chronic uncontrolled infection or with a history of immunodeficiency, including a positive HIV test result (ELISA and Western blot). An HIV test will not be required; however, previous medical history will be reviewed.
• Non-malignant medical illnesses that are uncontrolled or whose control may be jeopardized by the treatment with this study treatment.
• Life-threatening autoimmune and ischemic disorders.
14. Patients who have a history of another primary malignancy within the last year, with the exception of locally excised non-melanoma skin cancer and carcinoma in situ of uterine cervix. Patients who have had no evidence of disease from another primary cancer for 1 or more years are allowed to participate in the study.
