Clinical Trial Summary

GATLA 8-AML´07 trial is an multicenter phase III dose-optimization trial for the treatment of acute myeloid leukemias in children and adolescents. Patients are treated with a combination of intensive chemotherapy in combination with intrathecal-injection by CNS and haematopoietic stem cell transplantation.

The patients are stratified in a standard-group (SR) and a high risk-group (HR). SR was defined as FAB (French-American-British) M1/M2 with Auer rods; FAB M4eo or favorable cytogenetics [t(8;21)/AML1-ETO or inv(16) or t(16;16) and/or CBFB/MYH11)]; bone marrow blasts ≤5% on day 15. HR was defined as all others. SR patients were reclassified to the HR group if FLT3-ITD positive.

Based on the experience of the BFM group, it was decided to randomly evaluate whether the six-drug conventional consolidation stage can be replaced with the use of a consolidation based by block therapy on drugs of proven efficacy in AML with the aim of reducing residual disease, and the toxicity of this stage. Patients are randomized once the double induction is completed into those who will receive the conventional consolidation phase and those who will receive consolidation with the combination of high doses cytarabine and two different anthracyclines sequentially.

Description:

All patients in the trial, whether standard risk (SR) or high risk (HR), receive 2 Induction courses: AIE and HAM and then are randomized to continue with the consolidation phase: a conventional consolidation (Arm A) with 6 drugs vs 2 blocks of chemotherapy that are incorporated in this protocol (AI and haM) (Arm B) and then an Intensification phase with high doses of cytarabine and etoposide. The difference between the SR and AR groups is that the former don't continue with the maintenance phase, while those in HR receive 1 year of Maintenance if they don't have a histoidentical family donor. SR patients according to cytogenetics and with < 5% blasts in the bone marrow on day 15, haven´t indication for TCHP in 1st CR. HR patients, with a histoidentical family donor, will be transplanted in the 1st. CR after the Consolidation phases or the AI and haM blocks, according to the treatment arm that corresponded to them by randomization

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Determine if two-cycle consolidation reduced the cumulative incidence of relapse compared to conventional consolidation (CONS) among newly diagnosed pediatric patients with AML.	The GATLA 8-LMA-P'07 was a randomized trial including pediatric AML children in Argentina; the design was based on AML-BFM 98 with minor modifications.(10) Similar to AML-BFM 98, the trial compared two approaches to consolidation. The standard regimen was a 6-week consolidation phase (CONS), which was also used in AML-BFM 93 vs. the comparator regimen of two short chemotherapy cycles (two-cycle) with cytarabine plus idarubicin (AI) and high dose cytarabine plus mitoxantrone (haM). AML-BFM 98 previously demonstrated that haM was tolerable.10 We hypothesized that the two-cycle consolidation (two-cycle) would be associated with lower relapse rates related to dose intensification compared to the standard CONS approach.	72 months
Secondary	Evaluate Event-free survival (EFS) of pediatric patients with AML.	EFS was calculated from date of randomization to first event (death, resistant leukemia, relapse or secondary malignancy) or date of last follow-up.	72 months
Secondary	Evaluate Overall Survival (OS) of pediatric patients with AML.	OS was also calculated from date of randomization to date of death or date of last follow-up.	72 months
