Official title
Acute Myeloid Leukemia At Initial Diagnosis and/or Relapse in Children, Teenagers and Young Adults: Molecular Profiling, Multidrug Testing and MSC Interaction Studies - ALARM3
Overview
Pediatric acute myeloid leukemias are disease with poor prognosis (overall survival of 60-75%) and high relapse rate of 35-45% require further understanding of the underlying biological mechanisms. The main objective of this study is to establish a biological collection to evaluate the genomic profiling of leukemic cells from primary blasts at diagnosis and/or relapse to improve identification of the main genetic hits involved in resistance and could predict a high risk of relapse. Other objectives include the study of bone marrow mesenchymal stem cells and ex vivo drug testing.
Interventions
- Other Collection of blood sample of bone marrow (cohort 1)
* 3 additional tubes of blood sample (cohort 1), at diagnosis and upon relapse if relapse occurs * Bone marrow aspirate : 3 additional tubes (cohort 1), at diagnosis and upon relapse if relapse occurs - Other Collection of blood sample of bone marrow (cohort 2 and 3)
* 1 additional tube of blood sample (cohort 2 and 3 at inclusion) * Bone marrow aspirate: 1 additional tube (cohort 2 and 3 at inclusion)
Primary outcome measures
- Number of somatic mutations in leukemic cells between diagnosis and relapse identified by Next-Generation Sequencing (NGS) [Time frame: Up to 5 years]
Secondary outcome measures (12)
- Cumulative incidence of relapse (CIR) from remission status. [Time frame: Up to 5 years]
- Event Free Survival (EFS) [Time frame: Up to 5 years]
- Disease Free Survival (DFS) [Time frame: Up to 5 years]
- Number of mutations identified by WGS [Time frame: Up to 5 years]
- Expression profile (transcriptome) of mesenchymal stem cells [Time frame: Up to 5 years]
- Engraftment rate of primary leukemic cells [Time frame: Up to 5 years]
- Matched rate of genetic mutational (or expression) profile between derived cells from experimental models to primary leukemic cells [Time frame: Up to 5 years]
- Comparison of LSC signature profile of leukemic primary blasts at diagnosis and at relapse [Time frame: Up to 5 years]
- Cumulative incidence of relapse according to LSC signature profile of leukemic primary blasts at diagnosis and at relapse [Time frame: Up to 5 years]
- EFS according to LSC signature profile of leukemic primary blasts at diagnosis and at relapse [Time frame: Up to 5 years]
- DFS according to LSC signature profile of leukemic primary blasts at diagnosis and at relapse [Time frame: Up to 5 years]
- Ex vivo multidrug testing profile of leukemic primary blasts [Time frame: Up ot 5 years]
