Phase 3 — Testing in thousands of people, comparing the treatment against what doctors currently use. This is the last big step before approval.
This trial is testing PostbiotiX Comfort®, a postbiotic supplement designed to support gut health in children with autism spectrum disorder. Postbiotics are naturally occurring molecules created when beneficial bacteria break down food — they're different from probiotics because they don't contain live bacteria. Researchers want to see if this supplement can reduce digestive problems like constipation, diarrhea, and stomach pain, and whether it might also improve behavior in children with autism.
Many children with autism experience digestive problems that can make their overall symptoms worse, but safe treatment options are limited. This medication is being studied as a gentler alternative to other microbiota treatments, with the goal of improving both gut health and quality of life for these children.

You would visit the research center at the start to provide a stool sample for testing and complete health assessments. You would then take the postbiotic supplement daily for the study period. At the end of the study, you would return for follow-up visits where researchers will collect another stool sample and evaluate any changes in your digestive symptoms and behavior. The researchers will compare your results to other children with autism and typically developing children to understand if the treatment is helpful.
