Trial Information

A Phase I/II Trial of ABT-751 Combined With Dexamethasone, PEG-asparaginase, and Doxorubicin in Relapsed Acute Lymphoblastic Leukemia (ALL)

All patients will receive the 2 courses of chemotherapy unless medical complications prevent
the administration of some of the drugs. Treatment for the first 2 courses of therapy will
last about 2 months.

Treatment on this study will consist of a combination of 8 anti-cancer medications. The 8
anticancer medicines are ABT-751, dexamethasone, PEG-asparaginase, doxorubicin, cytarabine
(Ara-C), methotrexate (MTX), cyclophosphamide, and 6-thioguanine. All the drugs except
ABT-751 are well known anti-cancer drugs and have been used extensively in the treatment of

During the Phase I portion of this study, when you enroll, you will be given an assigned
dose of ABT-751. The dose of ABT-751 will be based on doses given in previous studies done
with adults and children. At each dose level of ABT-751, between 3 and 6 children will
receive ABT-751 in combination with chemotherapy. If the side effects are not too severe,
the next group of children will receive a higher dose. The dose will continue to be
increased until we find the dose that causes serious side effects. Your dose of ABT-751
will not be increased. If you have bad side effects, your dose may be decreased.

The dose used during the Phase 2 part of this study will be determined by the outcome of the
Phase I study. The highest dose used in Phase I that was tolerated without serious side
effects will be the one used in Phase 2.
