Summary

This trial is testing whether a therapy that has been shown to help children with ASD and GI problems will also help adults with ASD and GI problems.

Who is the study for?
Adults aged 18-60 with Autism Spectrum Disorder and long-term gastrointestinal issues, who haven't changed their treatment plans in the last 3 months. They must be able to swallow pills and have a close observer to report on their condition. Excluded are those with certain genetic disorders, recent antibiotics or probiotics use, other clinical trial participation, severe GI conditions like Crohn's Disease, or women who are pregnant without effective birth control.
What is being tested?
The trial tests Microbiota Transfer Therapy (MTT) for adults with ASD and GI problems. It involves using Vancomycin followed by MoviPrep (a bowel cleaning solution), then introducing Full Spectrum Microbiota to improve gut health and potentially reduce ASD symptoms based on previous positive results in children.
What are the potential side effects?
Possible side effects include digestive discomfort from Vancomycin and MoviPrep during the initial phases of therapy. The introduction of Full Spectrum Microbiota may cause changes in bowel habits or abdominal pain as the body adjusts to new gut bacteria.
