Busulfan Pharmacokinetic Analysis and GST Pharmacogenetic Profile in Adults Undergoing Hematological Stem Cell Transplantation
The correlation between Busulfan Pharmacokinetics in AML transplanted patients and their GST (A1,T1,M1 and P1), MDR-1 genetic profile. If a pre-genetic testing of those genes can be utilized as biomarkers of SOS and/or HGVHD. This study is not an interventional study it is only checking the GST gene and MDR-1 gene
Acute Myeloid Leukemia
|Study Design:||Time Perspective: Prospective|
- If GST and ABCB1 genes modify busulfan pharmacokinetics in AML patients who will be transplanted [ Time Frame: end of BMT transplantation ] [ Designated as safety issue: No ]If individuals diagnosed with AML carrying the GSTP1 variant allele rs1695 (heterozygotes) are at risk of developing supra-therapeutic BU AUC due to lower BU clearance, and if combined polymorphisms in GSTM1 and ABCB1 (3435 or 2677) are associated with BU clearance rates and AUC.

BU levels are largely unpredictable, patients are often exposed to the toxic effects of inappropriate drug regimens before dose modifications can be made. Although the importance of TDM cannot be over emphasized, it entails trial and error and does not allow for pre- treatment dose optimization. This study, which provides an integration of genetic and pharmacokinetic data analysis of patients preconditioned for HSCT with high dose oral BU, aims to define biomarkers predictive of poor BU metabolism and clearance to prevent potential drug toxicity.This study is not an interventional study, only investigates the GST and MDR-1 genes in correlation with the "routine" Busulfan AUC done during the preparative regimen in HSCT for AML patients.
