Abstract
Mucopolysaccharidosis type I-Hurler syndrome (MPS-IH) is a lysosomal storage disease characterized by multisystem morbidity and death in early childhood. Although hematopoietic cell transplantation (HCT) has been performed in these patients for more than 30 years, large studies on the long-term outcome of patients with MPS-IH after HCT are lacking. The goal of this international study was to identify predictors of the long-term outcome of patients with MPS-IH after successful HCT. Two hundred seventeen patients with MPS-IH successfully engrafted with a median follow-up age of 9.2 years were included in this retrospective analysis. Primary endpoints were neurodevelopmental outcomes and growth. Secondary endpoints included neurologic, orthopedic, cardiac, respiratory, ophthalmologic, audiologic, and endocrinologic outcomes. Considerable residual disease burden was observed in the majority of the transplanted patients with MPS-IH, with high variability between patients. Preservation of cognitive function at HCT and a younger age at transplantation were major predictors for superior cognitive development posttransplant. A normal α-l-iduronidase enzyme level obtained post-HCT was another highly significant predictor for superior long-term outcome in most organ systems. The long-term prognosis of patients with MPS-IH receiving HCT can be improved by reducing the age at HCT through earlier diagnosis, as well as using exclusively noncarrier donors and achieving complete donor chimerism.

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.
