Effect of HLA-matching recipients to donor noninherited maternal antigens on outcomes after mismatched umbilical cord blood transplantation for hematologic malignancy.

Abstract

Transplantation-related mortality (TRM) is high after HLA-mismatched umbilical cord blood (UCB) transplantation (UCBT). In utero, exposure to noninherited maternal antigen (NIMA) is recognized by the fetus, which induces T regulator cells to that haplotype. It is plausible that UCBTs in which recipients are matched to donor NIMAs may alleviate some of the excess mortality associated with this treatment. To explore this concept, we used marginal matched-pair Cox regression analysis to compare outcomes in 48 NIMA-matched UCBTs (ie, the NIMA of the donor UCB unit matched to the patient) and in 116 non-NIMA-matched UCBTs. All patients had a hematologic malignancy and received a single UCB unit. Cases and controls were matched on age, disease, disease status, transplantation-conditioning regimen, HLA match, and infused cell dose. TRM was lower after NIMA-matched UCBTs compared with NIMA-mismatched UCBTs (relative risk, 0.48; P = .05; 18% versus 32% at 5 years posttransplantation). Consequently, overall survival was higher after NIMA-matched UCBT. The 5-year probability of overall survival was 55% after NIMA-matched UCBTs versus 38% after NIMA-mismatched UCBTs (P = .04). When faced with the choice of multiple HLA-mismatched UCB units containing adequate cell doses, selecting an NIMA-matched UCB unit may improve survival after mismatched UCBT.

Kurtzberg

Joanne Kurtzberg

Jerome S. 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 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.
