Trial Information

Phase I Study of Induction Therapy With Cytarabine, High-Dose Mitoxantrone and Dasatinib for Patients With Philadelphia-Chromosome Positive (Ph+) Acute Lymphoblastic Leukemia (ALL): ALL-6 Protocol

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

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

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

- Patients with adequate renal function (creatinine < or = 2.0 mg/dl or creatinine
clearance > 50 ml/min).

- Patients with an LVEF > or = 50%.

- Karnofsky performance status > or = 20%.

- Ability to take oral medication (dasatinib must be swallowed whole).

- Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy
test (sensitivity > or = 25IU HCG/L) within 72 hours prior to the start of study drug
administration. Persons of reproductive potential must agree to use and utilize an
adequate method of contraception throughout treatment and for at least 6 months after
study drug is stopped. Prior to study enrollment, women of childbearing potential
must be advised of the importance of avoiding pregnancy during trial participation
and the potential risk factors for an unintentional pregnancy.

- concomitant Medications: Patient agrees to discontinue St. Johns Wort while receiving
dasatinib therapy (discontinue St. Johns Wort at least 5 days before starting
dasatinib); Patient agrees that IV bisphosphonates will be withheld for the first 8
weeks of dasatinib therapy due to risk of hypocalcemia.

- Signed informed consent, which indicates the investigational nature of this study,
within 30 days of treatment initiation, is required.

Exclusion Criteria:

- Female patients who are pregnant or lactating. Women and men of childbearing age
should use effective contraception.

- Patients with uncontrolled active infections.

- Patients who are receiving other systemic chemotherapy. Patients must have been off
prior antileukemic therapy for at least 2 weeks (hydroxyurea is considered

NOTE: Patients who had previously received combination therapy with cytarabine, high-dose
mitoxantrone and dasatinib will be excluded from the trial. All other prior therapies will
be allowed, including prior tyrosine kinase inhibitors usage. Prior dasatinib use will be
allowed (as a single agent or in combination therapy, other than the combination therapy
with cytarabine and high-dose mitoxantrone).

- Concomitant active secondary malignancy requiring treatment (other than squamous cell
and basal cell carcinoma of skin).

- Concurrent medical condition which may increase the risk of toxicity, including:
grade ≥ 2 pleural or pericardial effusion.

- Cardiac Symptoms; any of the following should be considered for exclusion:

- Uncontrolled angina, congestive heart failure or MI within (6 months).

- Diagnosed congenital long QT syndrome.

- Any history of clinically significant ventricular arrhythmias (such as
ventricular - tachycardia, ventricular fibrillation, or Torsades de pointes).

- Prolonged QTc interval on pre-entry electrocardiogram (> 450 msec).

- Subjects with hypokalemia or hypomagnesemia if it cannot be corrected prior to
dasatinib administration.

- History of significant bleeding disorder unrelated to cancer, including:

- Diagnosed congenital bleeding disorders (e.g., von Willebrand's disease).

- Diagnosed acquired bleeding disorder within one year (e.g., acquired anti-factor
VIII antibodies).

Ongoing or recent (< or = 3 months) significant gastrointestinal bleeding

- Concomitant Medications, any of the following should be considered for exclusion:

- Category I drugs that are generally accepted to have a risk of causing Torsades
de Pointes including: (Patients must discontinue drug 7 days prior to starting

- quinidine, procainamide, disopyramide amiodarone, sotalol, ibutilide, dofetilide
erythromycin, clarithromycin chlorpromazine, haloperidol, mesoridazine,
thioridazine, pimozide cisapride, bepridil, droperidol, methadone, arsenic,
chloroquine, domperidone, halofantrine, levomethadyl, pentamidine, sparfloxacin,
