E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
•To determine the feasibility and toxicity of dasatinib in combination with intensified chemotherapy in young patients with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia.
•To determine whether the intensification of tyrosine kinase inhibition (TKI) through the addition of dasatinib to induction therapy (on days 15-28) and the substitution of dasatinib for imatinib mesylate during post-induction therapy will lead to a 3-year event-free survival (EFS) in ≥ 60% of these patients. |
|
E.2.2 | Secondary objectives of the trial |
•To determine whether the addition of dasatinib to induction therapy will decrease levels of minimal residual disease (MRD) present at the end of induction therapy as compared with MRD levels in patients treated on COG-AALL0031.
•To determine whether early intensified TKI therapy (dasatinib) will lower levels of MRD at the end of consolidation therapy as compared with MRD levels in patients who received imatinib mesylate during blocks 1 and 2 consolidation therapy (cohorts 3-5) on COG-AALL0031.
•To determine the overall 3-year EFS rate for both standard- and high-risk patients treated with dasatinib.
•To determine the long-term effects of dasatinib on growth, development, and bone metabolism.
•To assess BCR-ABL mutation status at time of diagnosis and progression/relapse. |
