Familial Fecal Microbiota Transplant for Autism Spectrum Disorders

This study is looking at whether a Familial Fecal Microbiota Transplant (FMT) can help adults with Autism Spectrum Disorder (ASD) who also have gut problems. FMT involves using stool from a close family member. Before the FMT, participants will receive a 6-week treatment with Vancomycin, an antibiotic. The study wants to see if this treatment can improve social difficulties and language delays. Researchers will measure changes using tools like the ATEC, QoLA, and CARS-2 after 52 weeks. The study is currently unclear on its recruitment status and plans to enroll 10 participants who are at least 6 years old and have an ASD diagnosis confirmed by DSM-V criteria.

Study design
This is an open-label study, meaning everyone knows what treatment is being given. It plans to enroll 10 participants.
What's involved
Participants will receive a 6-week treatment with Vancomycin, followed by a Fecal Microbiota Transplant (FMT) given by colonoscopy. The study will measure outcomes at 52 weeks.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 52 weeks after the treatment to measure outcomes.
