A Randomized Study of Autologous Umbilical Cord Blood Reinfusion in Children With Cerebral Palsy

April 15, 2026 updated by: Joanne Kurtzberg, MD

Is Autologous Umbilical Cord Blood Reinfusion Beneficial in Children With Cerebral Palsy: A Randomized, Blinded, Placebo-Controlled, Crossover Study

The purpose of this study is to determine the efficacy of a single intravenous infusion of autologous umbilical cord blood (UCB) for the treatment of pediatric patients with spastic cerebral palsy.

Study Overview

Detailed Description

Cerebral palsy results from in utero or perinatal injury to the developing brain, often through stroke, hypoxic insult or hemorrhage. Currently available treatments for patients with cerebral palsy are supportive, but not curative. Umbilical cord blood (UCB) has been shown to lessen the clinical and radiographic impact of hypoxic brain injury and stroke in animal models. UCB also engrafts and differentiates in brain, facilitating neural cell repair, in animal models and human patients with inborn errors of metabolism undergoing allogeneic, unrelated donor UCB transplantation. We hypothesize that, in the setting of brain injury, infusion of autologous UCB will facilitate neural cell repair resulting in improved function in pediatric patients with cerebral palsy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Gross Motor Function Measure 66 (GMFM-66) Score
Time Frame: Baseline to Year 1
Change in Gross Motor Function Measure 66 (GMFM-66) Score from Baseline to Year 1. The GMFM-66 is a clinical tool used to evaluate gross motor function in children with cerebral palsy and is scored using a propriety software program called the Gross Motor Ability Estimator (GMAE) that produces an interval level continuous score ranging from 0 to 100. Higher scores indicate better motor function. A negative change in GMFM-66 score indicates a reduction in motor function, a positive change indicates improvement in motor function, and zero indicates no change in motor function.
Baseline to Year 1

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Peabody Gross Motor Quotient From Baseline to Year 1
Time Frame: Baseline to Year 1
The Peabody Developmental Motor Scales - Second Edition (PDMS-2) measures gross and fine motor skills in children from birth through five years of age. The Gross Motor Quotient score from the PDMS-2 was used in this study to evaluate gross motor function. The Gross Motor Quotient measures the ability to use large muscle systems for locomotion, maintain a stable posture when not moving, and throw/catch objects. The range of possible scores is 41 to 164. High scores indicate better gross motor function. Lower scores indicate less gross motor function ability. The change in Gross Motor Quotient from Baseline to Year 1 was evaluated in this study. Positive numbers indicate an increase in gross motor ability, negative numbers indicate decreases in gross motor function, and a zero indicates no change.
Baseline to Year 1
Change in IT-QOL Questionnaire Score
Time Frame: Baseline to Year 1
The Infant and Toddler Quality of Life Questionnaire (IT-QOL) was utilized for children ages one to three years at study entry.This 97-item questionnaire is completed by the parents and covers 12 concepts related to the physical, mental, and social well being of the child and the impact of their illness on the family. Scores range from 0 (worst health) to 100 (best health). The change from Baseline to Year 1 is summarized here for each of the 12 items on the questionnaire. Negative values indicate a decline in quality of life over time, positive values indicate an improvement, and zero indicates no change.
Baseline to Year 1
Change in CP-QOL Score
Time Frame: Baseline, Year 1
Children age four years or older at study entry were assessed using the disease-specific "CP-QOL Child" assessment tool as completed by a parent. The CP-QOL Child primary-caregiver proxy form is designed for children 4 - 12 with cerebral palsy and contains 66 items which assess physical, emotional, and social well being as well as access to services and acceptance by others. Scores are summarized in seven topic areas. Scores in each area range from 0 (worst health) to 100 (best health). The change score from Baseline to Year 1 is summarized here for each item. Negative scores indicated a decrease in quality of life, positive scores indicate an increase and zero indicates no change.
Baseline, Year 1
Change in Whole Brain Connectivity Measured by Diffusion Tensor Magnetic Resonance Imaging (MRI)
Time Frame: Baseline to Year 1
Change in number of connections in the brain as measured by diffusion tensor magnetic resonance imaging (MRI). Changes in connectivity are normalized to white matter volume of the brain. A positive number indicates an increase in connections, a negative number indicates a decrease, and zero indicates no change. The number of connections is expressed in terms of 10e5. For example, a change of 1 indicates an increase of 1x10e5 or 100,000 connections.
Baseline to Year 1
Change in Loes Score of Functional MRI From Baseline to Year 1 and From Year 1 to Year 2
Time Frame: Baseline, Year 1, Year 2

Baseline, Year 1, Year 2
Change in Bayley Scales of Infant and Toddler Development-III, Cognitive Composite From Baseline to Year 1
Time Frame: Baseline to Year 1
Cognitive function was assessed in English-speaking study participants using one of three different tools depending on the age of the patient at the time of assessment: The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), the Wechsler Intelligence Scale for Children (WISC-IV), and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III). Some patients were assessed with different tools at subsequent visits as they aged during the conduct of the trial. The Bayley-III is designed to assess developmental functioning of infants and toddlers. Scores for the Cognitive Composite range from 1 to 19 and results in the range of 8 to 12 are considered average. The outcome measure reported here is the change in Cognitive Composite between Baseline to Year 1. Positive numbers indicate increases in cognitive functioning, negative numbers indicate a decrease, and zero indicates no change.
Baseline to Year 1
Change in Wechsler Preschool and Primary Scale of Intelligence (WPPSI) III Full Scale Intelligence Quotient (IQ) for Younger Children (Ages 2 Years & 6 Months to 3 Years & 11 Months) From Baseline to Year 1.
Time Frame: Baseline to Year 1
Cognitive function was assessed in English-speaking study participants using one of three different tools depending on the age of the patient at the time of assessment: The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), the Wechsler Intelligence Scale for Children (WISC-IV), and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III). Some patients were assessed with different tools at subsequent visits as they aged during the conduct of the trial. There are two versions of the WPPSI-III for two different age ranges: 2 years & 6 months to 3 years & 11 months, and 4 years to 7 years & 3 months. The Full Scale IQ is calculated for both age ranges and provides a continuous score with an average of 100 and a standard deviation of 15. Change from Baseline to Year 1 was evaluated, with positive numbers indicating an increase in cognitive ability, negative numbers indicating a decrease in cognitive ability, and zero indicating no change.
Baseline to Year 1
Change in the Wechsler Intelligence Scale for Children (WISC-IV) From Baseline to Year 1.
Time Frame: Baseline to Year 1
Cognitive function was assessed in English-speaking study participants using one of three different tools depending on the age of the patient at the time of assessment: The Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III), the Wechsler Intelligence Scale for Children (WISC-IV), and the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-III). Some patients were assessed with different tools at subsequent visits as they aged during the conduct of the trial. The WISC-IV is designed for children 6 years 0 months to 16 years 11 months. This study used the Full Scale IQ, which ranges from 45 to 155 with a mean of 100 and standard deviation of 15. Higher scores indicate stronger cognitive function. Scores between 90 and 110 are considered to be within the range of average IQ.
Baseline to Year 1
Change in Cognitive Z-Score From Baseline to Year 1
Time Frame: Baseline to Year 1
Because patients in this study were evaluated with different cognitive assessments based on their age at the time of assessment (The Bayley-III Cognitive Composite, the WPSSI-III Full Scale IQ, and the WISC-IV Full Scale IQ Composite), with some patients being assessed using different tools at subsequent visits during the trial, a method for combining the assessments was employed to evaluate change in cognitive function over time in as many patients as possible. A cognitive Z-score was calculated for each participant at Baseline and Year 1 by adjusting each score by the relevant assessments' population mean and standard deviation. The Z-scores represent the distance from the population mean, as measured by standard deviations. The analysis presented here summarizes the change in Z-score between Baseline and Year 1. A positive number indicates an increase in cognitive function, a negative number indicates a decrease, and zero indicates no change.
Baseline to Year 1
Change in Assisting Hand Assessment (AHA) Score From Baseline to Year 1
Time Frame: Baseline to Year 1
The Assisting Hand Assessment (AHA) measures the use of hemiplegic cerebral palsy patients' involved hand in tasks involving two hands. The test is valid for ages 18 months to 12 years. The score is an interval scale ranging from 22 to 88 with higher numbers indicating more effective use of the affected hand in performance of bimanual tasks. Change in this score was evaluate between Baseline and Year 1. Positive numbers indicate more effective use of the affected hand, negative numbers indicate a reduction in the effective use of the affected hand, and a zero indicates no change.
