Exceptions:
• There is no time restriction in regard to prior intrathecal chemotherapy provided there is complete recovery from any acute toxic effects of such; it is allowable to enroll a patient that has received IT Cytarabine (ARA-C), IT Methotrexate (MTX) or triple IT therapy within 14 days of enrollment as part of their evaluation to diagnose disease relapse. The IT therapy given within 14 days of initiation of protocol specified chemotherapy, may substitute for the day 1 IT in cohorts A and B
• Subjects with rapidly progressive disease may receive hydroxyurea until they begin study therapy;
