This is a study for patients with relapsed acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML). Some people diagnosed with leukemia have changes in a receptor located on the surface of white blood cells called FLT3. This is known as a FLT3 mutation. FLT3 plays an important role in the way cells grow and divide. In normal cells, the FLT3 receptor is switched off most of the time and only switches on when it gets a chemical signal from outside. But cells with the FLT3 mutation have the grow signal permanently switched on. This means leukemia cells with the FLT3 mutation are growing and dividing all the time. Doctors have found that people with leukemia cells that carry FLT3 mutations are less likely to go into remission with chemotherapy and have a higher risk of the leukemia coming back after treatment.
This is a study of an investigational drug called AC220. AC220 is considered investigational because it has not been approved in the United States by the Food and Drug Administration (FDA). AC220 is a drug which is able to "turn off" the FLT3 grow signal. AC220 will be given with cytarabine and etoposide to treat the relapsed leukemia. This is a phase I study, which means that the study is being done to find the highest dose of AC220 that can be given safely with the drugs cytarabine and etoposide to children and young adults.

1000 mg/m2/day IV given every 12 hours on days 1 through 5.
IT cytarabine given intrathecally to patients with AML on day "0" of course 1 and 2. Dose defined by age
IT methotrexate given intrathecally to patients with ALL on day "0" of course 1 and 2. Dose defined by age
- The dose of AC220 that can be given safely with etoposide and cytarabine. [ Time Frame: 6 weeks ]The incidence of dose limiting toxicity (DLT) will be measured. The maximum tolerated dose will be the highest study dose at which 1 or fewer of six patients experience DLT during cycle 1 of therapy.
- The response rate after treatment. [ Time Frame: 10 weeks ]
- Composite pharmacokinetics of AC220. [ Time Frame: 3 years ]Measure the levels of AC220 in the blood during treatment.
- FLT-3 mutation in cancer cells before and after treatment. [ Time Frame: 3 years ]
- Inhibition of FLT3 phosphorylation [ Time Frame: 3 years ]
