- Unstable angina pectoris
- Significant uncontrolled cardiac arrhythmias, including ventricular arrhythmias, congenital long QT syndrome, symptomatic atrial fibrillation, symptomatic bradycardia, right bundle branch block plus left anterior hemiblock or bifasicular block
- QTc \>500 ms, uncorrectable by managing electrolytes and medications, using the QTcF formula in Appendix D.
- Active acute graft vs. host disease ≥ grade 2 or active extensive chronic GVHD
- Relapse after allogeneic stem cell transplantation prior to post-transplant day 30
- Active central nervous system (CNS) involvement of leukemia (lumbar puncture not required to rule out CNS involvement if not suspected)
- Uncontrolled psychiatric illness that would limit compliance with requirements

- Other medical or psychiatric illness or organ dysfunction or laboratory abnormality which, in the opinion of the investigator, would compromise the subject's safety or interfere with data interpretation.
