The Alzheimer’s, Autism, Cognitive Impairment Stem Cell Treatment Study (ACIST) is an IRB approved, NIH registered (NCT 3724136) using autologous (from the patient themselves) Bone Marrow-Derived Stem Cells in the treatment of Autism Spectrum Disorder (ASD) in patients over the age of 18. There are a number of preclinical and clinical publications suggesting that BMSC may be of help in various neurologic diseases. One of the more recent university-based studies, Autologous Umbilical Cord Blood Infusion for Children With Autism Spectrum Disorder (ASD) has been conducted at Duke University Medical Center in North Carolina. We are not substituting for the standard of care- we wish patients to have completed all routine treatment that is available before considering the ACIST study.
