Clinical Trial Summary

This study is designed to learn about early brain development in children with Krabbe disease, and to use diffusion tensor imaging as an early diagnostic tool to identify newborns at risk for the disease.

Description:

This study is designed to learn about early brain development in children with Krabbe disease and to use diffusion tensor imaging (DTI) as an early diagnostic tool to differentiate children with infantile Krabbe disease from newborns who are disease free but have very low enzyme levels. Additionally, this study will determine how certain structures in the brain will develop over 24 months in children with infantile Krabbe disease and those without disease who have low enzyme levels. This study will also reveal information about the learning and motor development of children, and will help researchers predict outcomes after treatment. Krabbe disease is a rare, childhood neurodegenerative disorder caused by galactocerebrosidase deficiency. It results in rapid demyelination, progressive spasticity, mental deterioration, blindness, deafness, seizures, and death. Based on previously published findings, treatment with unrelated umbilical cord blood transplantation is now standard for Krabbe disease, provided that the treatment occurs within the first weeks of life and before symptoms appear. Once newborns are identified through population screening, there is no objective measure to predict if the baby will develop the most frequent rapidly progressive infantile forms of Krabbe or have a slower juvenile or adult form. Phenotype and genotype correlations are not possible because there are more than 150 mutations that can cause the disease and many polymorphisms in the normal population that affect the enzyme level. There is an urgent clinical need to develop a predictive measure. To date, there are no available tools to classify infants into the infantile versus later forms. New advances in neuroimaging techniques have enabled scientists to quantify changes in brain growth and myelination early in life and before disease symptoms develop. Knowledge from this study will help identify the window of opportunity for early intervention and treatment to prevent severe disability, and may lead to better treatment strategies.
