This study looks at how safe and helpful a new treatment called AdiaVita is for people with Autism Spectrum Disorder (ASD). AdiaVita comes from umbilical cord blood-derived stem cells and exosomes, which are tiny bubbles that help cells communicate. The study also uses glutathione, a natural antioxidant that helps protect cells. The study will have about 100 people, aged 3 and up. Some will get AdiaVita with glutathione, and others will get a placebo (a fake treatment) with glutathione. The main goal is to see if the treatment helps improve ASD symptoms using a checklist called ATEC.

• The study lasts 12 months and includes several visits and tests.
• Participants must pay $12,000, but if eligible, they may receive more treatment later without extra cost.
• There is no guarantee the treatment will help, and there are risks like allergic reactions.

Participants must have a confirmed ASD diagnosis and be able to attend all visits. Some medical conditions, other trial participation, or pregnancy will exclude someone from joining.
