Preclinical and early phase clinical studies suggest that an appropriately dosed umbilical cord blood (CB) infusion has the potential to help improve motor function in young children with cerebral palsy (CP). As many children with CP do not have their own CB available, use of allogeneic cells would extend access to this potentially beneficial therapy to more children. In this phase I, open-label study, 15 children, aged 1 to 6 years, with moderate to severe spastic CP were treated with a single intravenous infusion of allogeneic human leukocyte antigen (HLA) matched or partially matched sibling CB with a cell dose of ≥2.5 × 10⁷ cells/kg based on the pre-cryopreservation count (median infused cell dose, 3.3 × 10⁷ ; range, 1.8-5.2 × 10⁷ ). There were a total of 49 adverse events (AEs) over a 2-year time period, but there were no AEs related to the CB infusions. Specifically, there were no acute infusion reactions and no antibody formation against platelets, red blood cells, or donor-specific HLA antigens. Donor cells were not detected in peripheral blood 6 months later. Six months after infusion, participants were assessed for response and experienced a mean ± SD increase of 4.7 ± 2.5 points on the Gross Motor Function Measure-66 and 1 ± 2.9 points on the Peabody Gross Motor Quotient. Appropriately dosed, allogeneic partially or fully HLA-matched sibling CB infusion is well tolerated and potentially beneficial in young children with CP.

Standardization, workforce development and advocacy in cell and gene therapies: a summary of the 2020 Regenerative Medicine InterCHANGE.
(Cytotherapy, 2021-10) McNiece, Ian K; Wacker, Kara K; Kurtzberg, Joanne; Warkentin, Phyllis I
Cell and gene therapy is a promising and disruptive new field of medicine for diseases lacking effective treatments. Collaboration among stakeholders has become critically important as investigators, health care providers, manufacturers, couriers, data registries, regulators and payers all become more invested in the success of this field. Many organizations have collaborated with each other to increase clarity, advocate for improvements and share lessons learned. These efforts appear to be making an impact, although the potential for duplicative efforts could slow progress. The second Regenerative Medicine InterCHANGE, hosted by the Foundation for the Accreditation of Cellular Therapy, took place at the Phacilitate Leaders World/World Stem Cell Summit conference in Miami, Florida, on January 24, 2020. Participants from several organizations outlined needs to advance cell and gene therapies. Efforts to address these include standardization, workforce development and advocacy. This article summarizes the major challenges and opportunities discussed during the InterCHANGE.
