Interest of a Therapeutic Follow-up of the Cytarabine in the Acute Myeloid Leukaemia: Is There Constitutional Biomarkers

In this open-label, single-center, non-randomized patients with AML (Acute Myeloid Leukemia) and receiving all induction chemotherapy and consolidation consisting of cytarabine under the care usual for this pathology, will be included. Each patient will be followed and for the development of toxicities, treatment response and progression-free survival. In addition to the usual care set out above, each patient will undergo a series of constitutional genetic investigations conducted by NGS on markers related to pharmacokinetics cytarabine. Another set of blood samples will also calculate, according to a Bayesian approach, individual pharmacokinetics of cytarabine and its metabolite, arabinosine-uracil. This study should allow the correlation between pharmacogenetics and patient plasma exposure, that would eventually balance improved efficacy / toxicity of this molecule through a customization regimens, achieved so far on a empirical basis. If validation of our data, a dosage of therapeutic pre CDA could help in predicting pharmacodynamics of cytarabine individual dose adjustment, as is done for the 5-FU and DPD.
