About the study

Thiotepa is a chemotherapy drug used extensively in bone marrow transplantation. Thiotepa is
a prodrug that undergoes metabolic conversion in the liver by CYP2B6 and CYP3A4 to its
primary active metabolite, TEPA. The goal of this study is to determine what causes some
children to have different drug concentrations of thiotepa and TEPA in their bodies and if
drug levels are related to whether or not a child experiences severe side-effects during
their bone marrow transplant. The hypothesis is that certain clinical and genetic factors
cause changes in thiotepa and TEPA drug levels in pediatric bone marrow transplant patients
and that high levels may cause severe side-effects.
