About the study

Fludarabine and clofarabine are chemotherapy drugs used extensively in bone marrow
transplantation. The goal of this study is to determine what causes some children to have
different drug concentrations of clofarabine and fludarabine 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 clinical and individual factors cause changes
in clofarabine and fludarabine drug levels in pediatric bone marrow transplant patients and
that high levels may cause severe side-effects.
