Brief Summary:
This research study is for people with a specific type of leukemia called Philadelphia chromosome positive acute lymphoblastic leukemia (the type the patients have). The investigators plan to give you combination of 3 drugs (dasatinib, mitoxantrone, cytarabine) for the first part of the chemotherapy (called Induction). The investigators have previously shown that the combination of mitoxantrone and cytarabine is very effective in your kind of leukemia. The purpose of this study is to establish a safe dose range of dasatinib in combination with this standard induction chemotherapy based on side effects. If possible, the trial will also give us an idea of how well this combination might work in treating your leukemia. Previous studies have shown that dasatinib can produce responses when given alone for your kind of leukemia. By using the dasatinib together with the chemotherapy, the investigators believe that we can kill even more leukemia cells than with either treatment alone. The investigators will initially treat patients with a low dose of dasatinib and monitor for side-effects. If the initial group of patients is able to tolerate this low-dose of dasatinib, then future patients will receive higher doses of dasatinib. Mitoxantrone and cytarabine chemotherapy is the standard therapy at the investigators' institution for the patient's leukemia and it is the combination of dasatinib with this chemotherapy that is new and investigational in this study.

Primary Outcome Measures :
  1. To determine the dose of dasatinib that can be safely administered with cytarabine, and high-dose mitoxantrone in patients with Ph+ ALL / lymphoid blast crisis of known chronic myelogenous leukemia. [ Time Frame: 5 years ]

Secondary Outcome Measures :
  1. To determine the toxicity of this combination in these patients. [ Time Frame: 5 years ]
  2. To determine Abl-mutational status at baseline and at the time of disease progression as a possible mechanism of resistance. [ Time Frame: 5 years ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Previously untreated and treated adult patients (> or = 18 years old) with a diagnosis of:

    • Philadelphia-chromosome positive acute lymphoblastic leukemia
    • Lymphoid blast crisis of known chronic myelogenous leukemia NOTE: Patients must have evidence of a t(9;22) in leukemic cells based on chromosomal or molecular analysis.

NOTE: The diagnosis must be confirmed by the pathology department at MSKCC. NOTE: It is recognized that newly diagnosed patients may be started on therapy with cytarabine and high-dose mitoxantrone (which is the standard of care at our institution for treating adult ALL) prior to the identification of t(9;22) in leukemic cells. These patients will remain eligible for participation on study and will be evaluable for response if it is possible to start treatment with dasatinib within 30 days of receiving induction chemotherapy.

  • Patients with adequate hepatic function (AST and ALT < or = 2.5 the institutional ULN, bilirubin < or = 2.0 mg/dl).
