A Phase II Proof-of-Concept Trial to Study Kinase Inhibition in Relapsed/Refractory Acute Leukemias: Using a Comprehensive In Vitro Kinase Inhibitor Panel to Select Individualized, Targeted Therapies

This phase II trial studies how well targeted therapy works in treating patients with acute
lymphoblastic leukemia or acute myelogenous leukemia that has come back after a period of
improvement or does not respond to treatment. Testing patients' blood or bone marrow to find
out if their type of cancer may be sensitive to a specific drug may help doctors choose more
effective treatments. Dasatinib, nilotinib, sunitinib malate, sorafenib tosylate, and
ponatinib hydrochloride may stop the growth of cancer cells by blocking some of the enzymes
needed for cell growth. Giving targeted therapy based on cancer type may be an effective
treatment for acute lymphoblastic leukemia or acute myelogenous leukemia.

PRIMARY OBJECTIVES:

I. To determine the clinical activity of kinase inhibitors using pre-clinical (in-vitro)
activity to select individual therapy.

SECONDARY OBJECTIVES:

I. To evaluate overall objective response rates (complete response plus partial response).

II. Determine overall survival (OS) and progression-free survival (PFS). III. Any changes in
transfusion requirements.

TERTIARY OBJECTIVES:

I. Prioritize active/aberrant kinase pathways using an in vitro inhibitor screen using
individual primary leukemia samples.

II. Measure "on target" in vivo kinase inhibition and signal transducer and activator of
transcription (STAT)-5 phosphorylation and correlate with response to treatment.

III. Perform next generation sequencing (whole exome sequencing) for complete mutational
analysis.

IV. Identify aberrant gene expression in primary leukemia samples from study subjects.

V. Evaluate pharmacokinetics for each individual kinase inhibitor during therapy.

OUTLINE: Patients are assigned to 1 of 5 treatment groups based on pre-clinical kinase
inhibitor activity.

GROUP I: Patients receive dasatinib orally (PO) once daily (QD) on days 1-28. Courses repeat
every 28 days in the absence of disease progression or unacceptable toxicity.

GROUP II: Patients receive nilotinib PO twice daily (BID) on days 1-28. Courses repeat every
28 days in the absence of disease progression or unacceptable toxicity.

GROUP III: Patients receive sunitinib malate PO QD on days 1-28. Courses repeat every 28
days in the absence of disease progression or unacceptable toxicity.

GROUP IV: Patients receive sorafenib tosylate PO BID on days 1-28. Courses repeat every 28
days in the absence of disease progression or unacceptable toxicity.

GROUP V: Patients receive ponatinib hydrochloride PO QD on days 1-28. Courses repeat every
28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.
