Autism Spectrum Disorder: cell-therapy evidence by therapy class
Across every stem-cell intervention, ClinicalTrials.gov holds 25 registered records for Autism Spectrum Disorder — 6 recruiting, 1 at Phase 3 or 4, in 14 countries. Snapshot 2026-08-29.
The condition, and why cells are proposed
Autism is a neurodevelopmental difference, not a lesion to repair, and that framing gap sits under every commercial offer. Registered studies typically test whether immune modulation changes specific behavioural measures. Development itself produces change over months, which is why uncontrolled reports of improvement in children are the least informative data in this entire field.
Therapy classes side by side
Counts come from separate registry queries per class; a study testing two interventions can appear in more than one row, so rows do not sum to the all-interventions total.
Geography of the research
United States accounts for about 38% of country mentions among sampled studies; 14 countries host at least one site.

The largest registered studies
Sorted by planned enrolment — size is not quality, but a 300-participant trial can answer questions a 12-participant series cannot.

Reading this honestly
Treat this as a map of research activity. It tells you whether a claim has an evidence programme behind it — not whether the treatment helped anyone. For Autism Spectrum Disorder specifically, the practical question is which registered study — if any — matches the product a provider is offering, and what its outcome measures actually are.
Frequently asked
How many stem-cell trials exist for Autism Spectrum Disorder?
25 registered records mention a stem-cell intervention for this condition (2026-08-29 snapshot), of which 6 were recruiting.
Which therapy class is furthest along for Autism Spectrum Disorder?
Ranked by Phase 3/4 records: MSC (0), HSCT (0), exosomes (0), PRP (0).
Does a recruiting trial mean I can be treated?
No. Trials have eligibility criteria, and joining one is not the same as buying a treatment. Paying a clinic for an unproven intervention outside a registered study gives you neither the protections nor the data collection of a trial.
