This study is a prospective Phase 1a open-label single- center trial. It will assess the safety of intrathecal administration of DUOC-01 cells to adults with Primary Progressive Multiple Sclerosis (PPMS). DUOC-01 is a population of cells expanded from donated human umbilical cord blood cells and is intended for treatment of neurodegenerative and demyelinating diseases. There will be approximately 20 participants enrolled. Exploratory objectives include changes in MS assessment scores, changes in brain MRI findings, and changes in blood biomarkers.

Augmentation of Umbilical Cord Blood Transplantation for Inherited Metabolic Diseases with Intrathecal Administration of Human Umbilical Cord Blood-Derived Oligodendrocyte-Like Cells

The primary objective of the study is to determine the safety and feasibility of intrathecal administration of DUOC-01 as an adjunctive therapy in patients with inborn errors of metabolism who have evidence of early demyelinating disease in the central nervous system (CNS) who are undergoing standard treatment with unrelated umbilical cord blood transplantation (UCBT). The secondary objective of the study is to describe the efficacy of UCBT with intrathecal administration of DUOC-01 in these patients.

Cellular Therapies: Yesterday, Today, and Tomorrow

Article

Author: Mayani, Hector

Cellular therapy (CT) can be defined as the transference into a person of healthy cells to correct defective functions. Yesterday (1950-2010), CT consisted mostly of hematopoietic transplants for the treatment of a variety of hematological disorders. Interestingly, during that period of time other cell types with therapeutic potential-including certain lymphoid populations and other nonhematopoietic cells-were discovered and characterized; thus, CT became a promising discipline for the treatment of a broader diversity of diseases. Today (2011-2023), CT has significantly grownup through preclinical studies and clinical trials, and it is currently progressing toward its consolidation as one of the pillars of medicine in the 21st century. Indeed, different types of stem cells (e.g., hematopoietic, mesenchymal, neural, and pluripotent), as well as different lymphoid and myeloid cell populations (e.g., TILs, CAR-Ts, CAR-NKs, and DUOC-01) are being used in clinical settings or are being tested in clinical trials. For the past decade, several CT modalities have been developed, and today, many of them are being used in the clinic. Tomorrow (2024-2040), already established CT modalities will surely be improved and applied more frequently, and novel therapies (that will include cell types such as iPSCs) will enter and expand within the clinical ground. It is noteworthy, however, that despite significant advancements and achievements, problems still need to be solved and obstacles need to be overcome. Technical, ethical, and economic issues persist and they need to be addressed. Undoubtedly, exciting times of challenges and opportunities are coming ahead in the CT arena.

BACKGROUND AIMSDUOC-01, a cell product being developed to treat demyelinating conditions, is composed of macrophages that arise from CD14⁺ monocytes in the mononuclear cell (MNC) population of banked cord blood (CB). This article demonstrates that expression of multiple gene products that promote remyelination is rapidly up-regulated during manufacturing of DUOC-01 from either MNC or purified CB CD14⁺ monocytes.METHODSCell cultures were initiated with MNC or with immunoselected CD14⁺ monocytes isolated from the same CB unit. Cell products present in these cultures after 2 and 3 weeks were compared by three methods. First, quantitative polymerase chain reaction was used to compare expression of 77 transcripts previously shown to be differentially expressed by freshly isolated, uncultured CB CD14⁺ monocytes and DUOC-01. Second, accumulation of 16 soluble proteins in the culture medium was measured by Bioplex methods. Third, whole transcriptomes of the cell products were compared by microarray analysis.RESULTSKey transcripts in multiple pathways that promote remyelination were up-regulated in DUOC-01, and substantial secretion of proteins corresponding to many of these transcripts was detected. Cell products manufactured from MNC or from CD14⁺ monocytes were similar with regard to all metrics. Upregulation of gene products characteristic of DUOC-01 was largely completed within 14 days of culture.CONCLUSIONWe demonstrate that expression of multiple gene products that promote remyelination is up-regulated during the first 2 weeks of manufacturing of DUOC-01. Measuring these mechanistically important transcripts and proteins will be useful in monitoring manufacturing, evaluating manufacturing changes, and developing mechanism-based product potency assays.

BACKGROUND AIMSCord blood (CB) transplantation slows neurodegeneration during certain inherited metabolic diseases. However, the number of donor cells in the brain of patients does not appear to be sufficient to provide benefit until several months after transplant. We developed the cell product DUOC-01 to provide therapeutic effects in the early post-transplant period.METHODSDUOC-01 cultures initiated from banked CB units were characterized by use of time-lapse photomicroscopy during the 21-day manufacturing process. Antigen expression was measured by means of flow cytometry and immunocytochemistry; transcripts for cytokines and enzymes by quantitative real-time polymerase chain reaction; activities of lysosomal enzymes by direct biochemical analysis; alloreactivity of DUOC-01 and of peripheral blood (PB) mononuclear cells (MNC) to DUOC-01 by mixed lymphocyte culture methods; and cytokine secretion by Bioplex assays.RESULTSDUOC-01 cultures contained highly active, attached, motile, slowly proliferating cells that expressed common (cluster of differentiation [CD]11b, CD14 and Iba1), M1 type (CD16, inducible nitric oxide synthase), and M2-type (CD163, CD206) macrophage or microglia markers. Activities of 11 disease-relevant lysosomal enzymes in DUOC-01 products were similar to those of normal PB cells. All DUOC-01 products secreted interleukin (IL)-6 and IL-10. Accumulation of transforming growth factor-β, IL-1β, interferon-γ and TNF-α in supernatants was variable. IL-12, IL-2, IL-4, IL-5 and IL-13 were not detected at significant concentrations. Galactocerebrosidase, transforming growth factor-β and IL-10 transcripts were specifically enriched in DUOC-01 relative to CB cells. PB MNCs proliferated and released cytokines in response to DUOC-01. DUOC-01 did not proliferate in response to mismatched MNC.CONCLUSIONSDUOC-01 has potential as an adjunctive cell therapy to myeloablative CB transplant for treatment of inherited metabolic diseases.
