  Outcome Measures
  Hide All Outcome Measures

1.  Primary:   Complete Remission   [ Time Frame: After induction therapy was completed (1 or 2 months) ]

Measure Type Primary
Measure Title Complete Remission
Measure Description Complete remission (CR) is defined as: <5% marrow aspirate blasts. Blasts can be >=5% if the blasts are found to be myeloid and there is no evidence of lymphoblasts by flow cytometry or immunostaining. Neutrophils >= 1000/mcl; platelets >100,000/mcl; and no blasts in the peripheral blood. C1 Extramedullary disease status as defined in the protocol. Complete remission with incomplete platelet recovery (CRi) is same as CR but platelet count may be <=100,000/mcl and/or ANC may be <1,000/mcl.
Time Frame After induction therapy was completed (1 or 2 months)  
Safety Issue No

2.  Secondary:   Number of Patients With Grade 3 Through 5 Treatment-Related Adverse Events   [ Time Frame: Up to 5 years ]

Measure Type Secondary
Measure Title Number of Patients With Grade 3 Through 5 Treatment-Related Adverse Events
Measure Description Only adverse events that are possibly, probably or definitely related to study drug are reported. Any CTCAE 4.0 event of Grade 3 (severe), Grade 4 (life threatening), or Grade 5 (fatal) which were deemed to be related to protocol treatment are included.
Time Frame Up to 5 years  
Safety Issue Yes
