Samiah Al-Zaidy, MD |VP of Clinical Development, Passage Bio
Dr. Samiah Al-Zaidy is VP of Clinical Development at Passage Bio, where she is leading the current Phase ½ gene transfer trial of PBKR03 in early-infantile Krabbe disease, GALax-C study as well as the overall development of the Krabbe program.
She is a pediatric neurologist with a background in neuromuscular disorders and clinical gene therapy. Dr. Al-Zaidy’s was formerly a principal investigator at the Center for Gene Therapy at Nationwide Children’s Hospital, where she co-led numerous AAV gene transfer studies of various methodology. She was one of the lead investigators in the clinical development of the Phase 1 and 3 gene transfer trials in spinal muscular atrophy that has led to the FDA approval of Zolgensma. Dr. Al-Zaidy also co-led the clinical development of several other AAV mediated gene therapy clinical trials that have been licensed to industry including the intravenous AAV micro-dystrophin gene therapy for Duchenne muscular dystrophy licensed to Sarepta as well as the CLN6 Batten’s intrathecal program that is currently licensed to Amicus. In her capacity as a consultant for Novartis Gene Therapies, she played a key role in the clinical development of their Phase 1 intrathecal studies and later the launch of Zolgensma in both the US and around the world. She has also supported other early-stage AAV biotech companies for their R&D and Clinical development programs
Andrea DeBarber, PhD | Associate Professor at Oregon Health & Science University
Andrea DeBarber, PhD, Research Associate Professor at Oregon Health & Science University (OHSU), Portland OR, oversees the OHSU Sterol Analysis Laboratory that performs blood and urine testing for diagnosis and therapeutic monitoring of cerebrotendinous xanthomatosis (CTX). Dr. DeBarber also oversees an independent research program at OHSU, where the focus of her research has been on developing improved diagnostic and screening tests for rare genetic disorders of sterol and bile acid synthesis. Most recently she has worked on developing LC-MS/MS based newborn screening for CTX. Left untreated, CTX can cause irreversible neurological damage, developmental and cognitive disability, and premature death. Early identification of this disorder, for example with newborn screening, would be highly significant as the burden of disease if left untreated can be profound, and morbidity and mortality easily prevented through early detection and intervention.
M. Christine Dorley, PhD | Assistant Director, NBS Laboratory TN DOH
M. Christine Dorley, PhD, currently serves as the Assistant Director of the Newborn Screening Laboratory for the Tennessee Department of Health, Division of Laboratory Services. She has been with the Division of Laboratory Services for close to 27 years serving in different capacities. Dr. Dorley became involved with Newborn Screening in 2004 temporarily overseeing the area in the absence of the lab manager and during a critical period in which screening for inborn errors of metabolism by Tandem Mass Spectrometry was added to the Tennessee panel. Soon, Newborn Screening became her passion, so she permanently moved to the section in 2007. Since then, Dr. Dorley has been instrumental in migrating the Newborn Screening laboratory to a seven-day workweek with a significant decrease in turnaround time for reporting results. Under her leadership, the laboratory has quickly adopted and implemented screening tests to match the core disorders on the Recommended Uniform Screening Panel (RUSP) for the United States and other non-RUSP disorders to include Fabry, Gaucher, and Krabbe. She is a member of the Association of Public Health Laboratories and serves on several committees including the NewSteps steering committee and the Hemoglobinopathies laboratory workgroup. She has also served on several document development committees for the Clinical & Laboratory Standards Institute.

Joanne Kurtzberg, MD | Jerome Harris Distinguished Professor of Pediatrics
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 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.

Joe Orsini, PhD | New York Newborn Screening Program
Dr. Joseph Orsini is the Deputy Director for the New York Newborn Screening Program. Dr. Orsini’s laboratory was the first to implement newborn screening for Krabbe disease (KD), applying the research method of Gelb and coworkers to high throughput screening. Dr. Orsini worked with Genzyme (Currently Sanofi) in developing a test that could screen for psychosine, this is a substrate of galactocerebrosidase, the enzyme that is deficient in Krabbe disease patients. This and three additional studies showed that psychosine is very elevated in newborns that will be affected by the infantile form of KD. Additionally, the testing shows that second tier testing for psychosine can significantly reduce the number of false positive KD. Dr. Orsini is working with Gelb, Matern, the New York State Krabbe Consortium, and the Krabbe Disease Task Force to redefine who is at risk for late onset KD; the new definition of which patients are truly at risk should reduce the number of infants with possible late onset KD by at least a factor of three. This work will provide the foundation for a successful nomination of Krabbe disease to the RUSP.
