Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) can retard the progression of early infantile Krabbe disease (EIKD). Superior outcomes are achieved if HSCT is performed prior to the onset of symptoms, however little information is available about the long-term outcomes in surviving patients. We now describe functional outcomes in pre-symptomatic infants who underwent HSCT for EIKD at ≤2 months of life. Records of the 19 patients who underwent HSCT for EIKD at ≤2 months of age from 1996-2010 were reviewed. Long-term functional outcomes were compared between those transplanted at <30 days and ≥30 days of life. Median age at transplant was 27 days (range 19-61). Median follow-up of the cohort was 12.6 years. Overall survival at 5 and 10 years post-transplant was 84.2% (95% CI:58.7-94.6%) and 78.6% (95% CI:52.5-91.4%), respectively. More favorable outcomes were seen in patients who underwent HSCT at <30 days of age, particularly in domains of mobility (p=0.01), communication (p=0.02), and feeding (p=0.008). Improved functional outcomes were observed when HSCT was performed in the first month of life, defining a critical period for intervention. These results support the implementation of newborn screening to enable rapid diagnosis and early treatment of infants with EIKD.

Joanne Kurtzberg
Dr. Kurtzberg is an internationally renowned expert in pediatric hematology/oncology, pediatric blood and marrow transplantation, umbilical cord blood banking and transplantation, and novel applications of cord blood and birthing tissues in the emerging fields of cellular therapies and regenerative medicine. Dr. Kurtzberg serves as the Director of the Marcus Center for Cellular Cures (MC3), Director of the Pediatric Transplant and Cellular Therapy Program, Director of the Carolinas Cord Blood Bank, and Co-Director of the Stem Cell Transplant Laboratory at Duke University. The Carolinas Cord Blood Bank is an FDA licensed public cord blood bank distributing unrelated cord blood units for donors for hematopoietic stem cell transplantation (HSCT) through the CW Bill Young Cell Transplantation Program. The Robertson GMP Cell Manufacturing Laboratory supports manufacturing of RETHYMIC (BLA, Enzyvant, 2021), allogeneic cord tissue derived and bone marrow derived mesenchymal stromal cells (MSCs), and DUOC, a microglial/macrophage cell derived from cord blood.
Dr. Kurtzberg’s research in MC3 focuses on translational studies from bench to bedside, seeking to develop transformative clinical therapies using cells, tissues, molecules, genes, and biomaterials to treat diseases and injuries that currently lack effective treatments. Recent areas of investigation in MC3 include clinical trials investigating the safety and efficacy of autologous and allogeneic cord blood in children with neonatal brain injury – hypoxic ischemic encephalopathy (HIE), cerebral palsy (CP), and autism. Clinical trials testing allogeneic cord blood are also being conducted in adults with acute ischemic stroke. Clinical trials optimizing manufacturing and testing the safety and efficacy of cord tissue MSCs in children with autism, CP and HIE and adults with COVID-lung disease are underway. DUOC, given intrathecally, is under study in children with leukodystrophies and adults with primary progressive multiple sclerosis.
In the past, Dr. Kurtzberg has developed novel chemotherapeutic drugs for acute leukemias, assays enumerating ALDH bright cells to predict cord blood unit potency, methods of cord blood expansion, potency assays for targeted cell and tissue based therapies. Dr. Kurtzberg currently holds several INDs for investigational clinical trials from the FDA. She has also trained numerous medical students, residents, clinical and post-doctoral fellows over the course of her career.
