CBR is committed to advancing newborn stem cell research for conditions that currently have no cure. With our support, researchers at Sutter Medical Center conducted an FDA-regulated clinical trial to evaluate the safety and preliminary effectiveness of cord blood as a potential treatment for Autism Spectrum Disorder (ASD).¹ We are hopeful that these study results will open the door for more research opportunities in the future!

What is ASD?

ASD is a childhood developmental disorder that impacts language abilities and social interactions, and can cause involuntary, repetitive behavior.² In the United States alone, about 1 in 68 children is currently affected by ASD.³ An exact cause of ASD still has not been discovered. However, some research suggests that a dysfunctional immune system may play a role in the development of some cases of ASD, causing damage within the nervous system and developing brain.^2,4 Because of this finding, there is interest in identifying treatments that could “calm” this type of immune response.

Why are scientists interested in cord blood for ASD?

Preliminary research has shown that cells found in cord blood have the ability to modulate or reduce inflammation and certain immune responses as well as travel to sites of neurological injury.^5,6 Because of these properties, cord blood may be a potential therapeutic target for ASD.

How was cord blood studied in this clinical trial?

A recent study by Sutter Medical Center evaluated 29 children with ASD who were administered their own cord blood, to assess safety and preliminary treatment effectiveness. Every child in the study had their own cord blood stored at birth with CBR. First, the children were given either an infusion of their own cord blood or a saline solution-based placebo and were then monitored for 24 weeks. At the end of 24 weeks, the children who had received cord blood were given saline solution, and the children who had received saline solution were given their own cord blood. They were then monitored for another 24 weeks.^1,7 Research is still in early stages, but we’re excited about the insights that will be gained from these trial results!

What were the results, and what are the next steps?

The study demonstrated that an infusion of a child’s own cord blood was safe and feasible, which is an important step. Researchers believe that these findings warrant further research to see if cord blood may be an effective treatment for ASD.¹ Fortunately, a new, larger study by Duke University has already begun.

• Researchers at Duke University are currently conducting a study to test the effectiveness of cord blood therapy in a greater number of children with ASD8 (recruitment for this trial has ended).

• CBR continues to keep our clients informed and connected. We encourage our clients to participate in the Family Health Registry, where we identify conditions common among CBR families, such as ASD. This helps us learn more about the conditions and connect individuals who are candidates with clinical trials studying new potential treatments.
