Official Title: An Open-Label, Randomized, Multicenter Phase 2 Trial of Dasatinib (SPRYCEL®) vs. Dasatinib Plus Smoothened Antagonist (BMS-833923) in the Treatment of Subjects With Newly Diagnosed Chronic Phase Philadelphia Chromosome Positive Chronic Myeloid Leukemia (CML).

Primary Outcome Measures:
  • To compare Major Molecular Response (MMR) rates for dasatinib alone versus dasatinib combined with SMO-antagonist in newly diagnosed Chronic Phase (CP) CML subjects (who did not achieve MMR within 1 year of treatment with dasatinib alone). [ Time Frame: Within 18 months from start of treatment ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Complete molecular response at any time [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
  • Progression-free survival, measured by the time from start of treatment to progression or death [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
  • Event-free survival, measured by the time from start of treatment to progression, death or treatment discontinuation [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
  • Transformation-free survival measured by the time from start of treatment to criteria for accelerated or blast phase CML are met and death [ Time Frame: Approximately 5 years ] [ Designated as safety issue: No ]
  • Safety of combination, measured by incidence of Serious Adverse Events and Adverse Events, deaths, laboratory values, and results of Electrocardiogram (ECG) will be assessed [ Time Frame: Approximately 5 years ] [ Designated as safety issue: Yes ]

Drug: Dasatinib

Capsules, Oral, dose to be determined, Once daily, approximately 2 years depending on response

Detailed Description:
  1. Design:

    Study Design and Duration as current described are no longer applicable since enrollment was prematurely concluded due to a decision by the sponsor. Subjects currently enrolled in the trial will continue to receive dasatinib alone at a starting dose of 100 mg QD for:

    1. a maximum of 5 years after entry into the study
    2. until progression by Investigators determination/judgment
    3. intolerance to Dasatinib
    4. the study is terminated due to safety concerns or
    5. other administrative reasons as communicated by the sponsor
  2. Research Hypothesis :

The research hypothesis and primary objective of this study as originally designed are no longer applicable as subjects enrolment has been terminated due to administrative reasons by the sponsor. The objective of the altered design of this study is to describe the safety profile and tolerability of dasatinib
