What is the success rate of stem cell therapy for Autism Spectrum Disorder?
No defensible universal success rate exists. Definitions, products, measures, populations and follow-up differ, and promotional responder figures often lack a comparator, prespecified endpoint or complete follow-up. Ask for absolute results from the exact protocol and outcomes meaningful to the child.
What the evidence shows for Autism Spectrum Disorder
Human evidence remains investigational and product-specific. Small or uncontrolled studies cannot reliably separate an intervention from maturation, concurrent support, expectation or assessor bias. The FDA patient information on regenerative medicine therapies states that these therapies have not been approved in the United States to treat autism. Families should verify an exact authorised trial and seek independent developmental or paediatric review.
