half-lives, whichever is longer if the immediate prior regimen included only weekly
chemotherapy; or 4 weeks or 5 half-lives, whichever is longer, from any therapy with
therapeutic biologics and from any type of investigational therapy. Daily hydroxyurea
for up to 2 weeks to keep the absolute blast count below 50 x 10⁹/L will be allowed,
but must be discontinued 24 hours prior to administration of study drug. Hydroxyurea

- Female patients must either be of non-childbearing potential, or, if of childbearing
potential, have a negative urine pregnancy test at screening and agree not to try to
become pregnant during the study and for 45 days after the final study drug
administration. Women of childbearing potential, if heterosexually active, must agree
to use 2 forms of highly effective birth control as determined by the protocol,
starting at screening, throughout the study period and for 45 days after the final
study drug administration.

- Female patients must agree not to breastfeed at screening, throughout the study period
and for 45 days after the final study drug administration.

- Male patients with female spouse/partner of childbearing potential, must agree to use
2 forms of highly effective birth control as determined by the protocol, starting at
screening, throughout the study period and for 45 days after the final study drug
administration.

Exclusion Criteria:

- Patient has a diagnosis of Acute Promyelocytic Leukemia (APL) or chronic myelogenous
leukemia in blast crisis.

- If patient is post allogenic transplant and requires therapy for graft vs host disease
(GVHD) within 14 days prior to date of screening.

- Recent history of cardiac ischemic disease (acute myocardial infarction within 6
months; uncontrolled angina); severe uncontrolled ventricular arrhythmia; recent
transient ischemic attack or stroke within 6 months of screening; poorly controlled
hypertension (systolic blood pressure >140 mm Hg or diastolic blood pressure >90 mm
Hg).

- Patient has active, untreated central nervous system (CNS) disease.
