RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. It is not yet known which combination chemotherapy regimen is more effective in treating young patients with acute lymphoblastic leukemia.
PURPOSE: This partially randomized phase III trial is studying how well combination chemotherapy works in treating young patients with relapsed or refractory acute lymphoblastic leukemia.

|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||470 participants|
|Official Title:||ALLR3: An International Collaborative Trial for Relapsed and Refractory Acute Lymphoblastic Leukaemia (ALL)|
|Study Start Date :||October 2002|
|Actual Primary Completion Date :||January 2010|
|Actual Study Completion Date :||December 2011|
Experimental: Arm I (induction therapy)
Patients receive idarubicin IV over 1 hour on days 1 and 2; oral dexamethasone twice daily on days 1-5 and 15-19; intrathecal (IT) methotrexate on days 1 and 8; vincristine sulfate IV on days 3, 10, 17, and 24; and pegaspargase intramuscularly (IM) on days 3 and 17 or asparaginase IM on days 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, and 25.
Drug: vincristine sulfate
Experimental: Arm II (induction therapy)
Patients receive mitoxantrone IV over 1 hour on days 1 and 2. Patients also receive dexamethasone, methotrexate, vincristine sulfate, and pegaspargase or asparaginase as in arm I.
Drug: mitoxantrone hydrochloride
Drug: vincristine sulfate
- Progression-free survival (PFS) of United Kingdom (UK) patients stratified by risk groups
- Evaluation of whether a minimal residual disease (MRD) level of 10(-4) is a suitable criterion at the end of induction therapy on which to decide whether chemotherapy or stem cell transplantation will be most beneficial to patients with intermediate- ...
- MRD as a surrogate marker for treatment response and PFS
- Comparison of PFS, MRD level at day 35, and toxicity as response variables in patients randomized to receive induction therapy with mitoxantrone hydrochloride or idarubicin
- PFS of all patients (UK, Dutch, Australian, and New Zealand) stratified by risk groups
- Comparison of PFS and overall survival between patients enrolled in this study and patients enrolled in R2 or I-BFM
- Evaluation of whether pre-stem cell transplantation cytoreduction (FLAD) reduces tumor load and how it affects outcome following transplant
