Primary Outcome Measures
NameTimeMethod
3-year Event-free Survival (EFS) RateFrom first dose to 3 years following first dose

3-year EFS rate is defined as the percentage of participants without event after 3 years since the start of study treatment.

Events for EFS are defined as ANY first one of the following:

* Lack of complete response in bone marrow

* Relapse at any site

* Development of second malignant neoplasm

* Death from any cause

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Negative for Minimal Residual Disease (MRD)From first dose to End of Induction Period Ia (up to 5 weeks) or Ib (up to 9 weeks) or End of Consolidation Period (up to 22 weeks)

MRD was by real-time qPCR for clone-specific immunoglobulin and T-cell receptor gene rearrangements (IG/TCR). Participants were declared as MRD negative if the MRD level is undetectable providing the assay lower limit of quantification is at least 0.1%

Event-Free Survival (EFS) Rate (Kaplan-Meier Estimates)From first dose to 3 years or 5 years following first dose

Overall estimation of the EFS of dasatinib plus chemotherapy was performed utilizing the Kaplan-Meier (KM) Product Limit method. The 3-year and 5-year EFS rates were computed with the corresponding 95% CI's using Greenwood's formula. Analyses of EFS included KM plots with number of patients at risk. Participants who neither relapse nor die or who are lost to follow-up were censored on the date of their last bone marrow, CSF assessment or physical exam, whichever occurred last.

Complete Remission RateFrom first dose to End of Induction Period Ia (up to 5 weeks) or Ib (up to 9 weeks) or End of Consolidation Period (up to 22 weeks)

Complete Remission rate is defined as the percentage of participants achieving a complete remission, i.e. \< 5% lymphoblasts in bone marrow and in CSF, with no evidence of other extramedullary disease. Complete remission will be assessed at the end of Induction IA, end of induction IB and end of the consolidation period for all treated participants.

Percentage of Participants With BCR-ABL Mutations at Baseline and at Time of Disease Progression or RelapseAt baseline (prior to start of study treatment) and at disease progression or relapse (up to approximately 3 years)

A BCR-ABL mutation is defined as the presence of a detectable amino acid substitution in the ABL kinase domain, assessed by Real-time quantitative PCR.

Number of Participants Experiencing Adverse EventsFrom first dose to 100 days following last dose (up to approximately 23 months)

Number of participants experiencing different types of all causality all grade adverse events
