Descriptive Information
Brief Title  ICMJE MGTA-456 in Patients With Inherited Metabolic Disorders Undergoing Hematopoietic Stem Cell Transplantation (HSCT)
Official Title  ICMJE A Phase 2, Single-arm, Open-label Study to Evaluate the Safety and Efficacy of MGTA-456 in Patients With Inherited Metabolic Disorders (IMD) Undergoing Hematopoietic Stem Cell Transplantation (HSCT)
Brief Summary This study is designed to assess the safety and efficacy of using MGTA-456 in patients with Inherited Metabolic Disorders (IMD) undergoing stem cell transplantation.
Detailed Description This phase 2 study is designed to evaluate the safety and efficacy of MGTA-456 in patients with IMD after receiving myeloablative conditioning and HSCT. MGTA-456 is an expanded CD34+ cell therapy product candidate given to induce rapid and sustained hematopoietic engraftment. In patients with selected IMDs, transplant is expected to replace defective or missing protein and preserve neurodevelopment. Since MGTA-456 offers increased numbers of HSCs over standard umbilical cord blood, it is expected to reduce the risks of prolonged neutropenia and thrombocytopenia and graft failure, and potentially transplant-related mortality (TRM). Patients with Hurler syndrome (also referred to as mucopolysaccharidosis-1H (MPS-1H)), cerebral adrenoleukodystrophy (cALD), metachromatic leukodystrophy (MLD) or globoid cell leukodystrophy (GLD) (also referred to as Krabbe disease) are eligible for this study.
