Participants were infants born at less than 28 weeks\u2019 completed gestation who received autologous UCBCs in the CORD-SaFe study at Monash Children\u2019s Hospital, Australia. A contemporaneous cohort of noninfused infants born during the study period was included for comparison. Data were analyzed from October to December 2024.<\/jats:p>\n <\/jats:sec>\n \n Intervention<\/jats:title>\n Autologous UCBC administered intravenously in the second postnatal week of life.<\/jats:p>\n <\/jats:sec>\n \n Main Outcomes and Measures<\/jats:title>\n Infants underwent brain magnetic resonance imaging to assess structure and injury (Kidokoro score) at term-equivalent age. Assessments at 52 to 54 weeks postmenstrual age included General Movements Assessment, Hammersmith Infant Neurological Examination score, and clinical examination to diagnose risk of cerebral palsy.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n A total of 23 infants (median [IQR] gestation, 26 [25-27] weeks; median [IQR] birth weight, 748 [645-981] grams; 17 [73.9%] male) were administered UCBCs at a median (IQR) dose of 42.3 (31.1-63.2) million cells\/kg. The contemporaneous cohort included 93 infants (median [IQR] gestation, 26 (24-27) weeks; median [IQR] birth weight, 769 [660-1017] grams; 39 [41.9%] male). Median (IQR) Kidokoro score was 2 (1-3) for the UCBCs group and 3 (2-5) for the contemporaneous cohort, with no statistically significant difference observed between the groups (adjusted median difference, 0 [95% CI, \u22121.78 to 1.78]). No infants in the UCBC group were assessed as high risk for cerebral palsy compared with 6 of 87 assessed infants (6.8%) in the contemporaneous group; however, the difference was not statistically significant (adjusted log odds, 0.31 [95% CI, \u22120.76 to 1.38]). No differences in Hammersmith Infant Neurological Examination score (adjusted log odds, \u22121.50 [95% CI, \u22125.78 to 2.78]) and absent fidgety movements (adjusted odds ratio, 0.24 [95% CI, 0.20 to 3.04]) were observed between groups.<\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n This phase 1 nonrandomized clinical trial assessing the safety and feasibility of autologous UCBCs in extremely preterm infants did not find significant differences in brain imaging parameters and early neurodevelopmental outcomes between the cell therapy and contemporaneous untreated groups. It was encouraging to note no infants who received UCBCs were assessed as high risk for cerebral palsy at 52 to 54 weeks postmenstrual age, and the absence of high risk for CP merits further
