Fecal transplants for autism deliver success in clinical trials
A two-year clinical trial by Arizona State University found that fecal microbiota transplants can reduce autism symptoms by up to 45 percent in children. The treatment, which involved a bowel cleanse and daily transplants over several weeks, also led to lasting improvements in gastrointestinal issues. Symptoms continued to improve over time, with many participants moving from severe to mild or non-diagnosable levels of autism two years post-treatment.
- ▪The study involved children with autism who had lower gut microbiome diversity compared to neurotypical children.
- ▪Two years after treatment, 44% of participants fell below the cutoff for mild autism spectrum disorder.
- ▪Autism symptoms decreased by 24% at the eight-week mark and improved to 45% reduction at two years.
- ▪Gastrointestinal problems, common in autistic children, also significantly improved following the treatment.
- ▪The research is advancing to a larger Phase 3 placebo-controlled clinical trial to confirm results.
