Eligibility
Key inclusion criteria

2. Patients with LLy must have measurable disease documented by clinical, radiologic
or histologic criteria

patients = 16 years of age.

- Prior Therapy A. Prior therapeutic attempts

- Phase 1 - Any patients with relapsed/refractory ALL or LLy

- Phase 2

1. B-cell ALL/LLy: all patients must have failed two or more therapeutic
attempts.

2. T-cell ALL/LLy: all patients must have failed one or more therapeutic
attempts. B. Recent prior chemotherapy Patients must have fully recovered
from the acute toxic effects of all prior chemotherapy, immunotherapy, or
radiotherapy prior to entering this study.

- Myelosuppressive chemotherapy: At least 14 days must have elapsed since the
completion of myelosuppressive therapy. However, patients may receive any of the
following medications within 14 days without a "wash-out" period:

the start of protocol therapy.

- "Maintenance-style" therapy - Therapy including vincristine (dosed at a maximum
of one-time weekly), oral 6-mercaptopurine, oral methotrexate (dosed at a maximum
of one-time weekly), dexamethasone (dosed at = 3 mg*/m^2/dose twice daily), and
prednisone (dosed at = 20 mg*/m^2/dose twice daily) can be initiated and/or
continued for up to 24 hours prior to the start of protocol therapy.

- Doses can be rounded to adjust for pill size

C. Hematopoietic stem cell transplant: Patients who have experienced their relapse after a
