What is the mechanism of action of this treatment?

Common treatments for Autism Spectrum Disorder (ASD) include behavioral and educational interventions, which work by enhancing communication, social skills, and adaptive behaviors through structured and individualized programs. These interventions often involve a high staff-to-student ratio, family involvement, and ongoing program adjustments. In terms of gut microbiota restoration, treatments like Microbiota Transfer Therapy (MTT) aim to re-establish a healthy balance of intestinal microbes, which may influence neurological and immune functions. This is significant for ASD patients as emerging research suggests a link between gut health and behavioral symptoms, potentially offering a novel approach to managing ASD symptoms.

What side effects are associated with this type of intervention?

Common treatments for Autism Spectrum Disorder (ASD) that focus on restoring healthy gut microbiota include probiotics and fecal microbiota transplantation (FMT). Probiotics are generally considered safe with few side effects, but they can occasionally cause mild gastrointestinal symptoms such as gas and bloating. FMT, while showing some promise in reducing gastrointestinal symptoms in ASD, can have more significant risks including infection, allergic reactions, and, in rare cases, serious complications like sepsis. Both treatments require further research to fully understand their safety profiles and long-term effects.

What prior FDA approvals exist?

As of now, there are no FDA-approved treatments specifically targeting the restoration of healthy gut microbiota for Autism Spectrum Disorder (ASD). The FDA has approved medications such as risperidone and aripiprazole to address irritability associated with ASD. These medications do not focus on gut microbiota but rather on managing behavioral symptoms. Microbiota Transfer Therapy (MTT) is still under investigation and has not yet received FDA approval for the treatment of ASD.

What other types of research exist?

Promising novel alternatives to Microbiota Transfer Therapy (MTT) for Autism Spectrum Disorder (ASD) patients include the use of prebiotics and probiotics. These therapies aim to modulate the gut microbiota and have shown potential benefits in various studies. Additionally, synbiotics, which combine prebiotics and probiotics, have demonstrated efficacy in improving gastrointestinal symptoms and possibly behavioral symptoms in ASD patients. Further research and clinical trials are needed to confirm their effectiveness and safety.

Summary

This trial will study whether Microbiota Transfer Therapy is an effective treatment for children with Autism Spectrum Disorder and gastrointestinal problems.

Who is the study for?

This trial is for children aged 5-17 with Autism Spectrum Disorder and gastrointestinal issues like constipation or diarrhea. They must be able to swallow pills, have stable health aside from GI problems, and not plan any treatment changes during the study. Kids on psychotropic meds, recent antibiotics, probiotics, or those with severe GI conditions are excluded.Check my eligibility

What is being tested?

The trial tests Microbiota Transfer Therapy (MTT) in kids with ASD and GI disorders. It starts with a 10-day course of vancomycin (an antibiotic), followed by a bowel cleanse, then a 12-week Fecal Microbiota treatment. Some participants will receive placebos instead of actual treatments for comparison.See study design

What are the potential side effects?

Possible side effects include reactions to vancomycin such as rash or allergic responses; digestive issues due to Miralax like bloating or cramps; and potential risks associated with microbiota transfer including abdominal discomfort.
