What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a treatment for people with Autism Spectrum Disorder that involves taking an antibiotic for a period of time followed by a procedure involving gut health from a family member. The goal is to improve social skills and language by enhancing gut health.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop all current medications, but you must refrain from taking non-study antibiotics and certain medications like loperamide, diphenoxylate/atropine, or cholestyramine. If you are on opiate treatment, you must be on a stable dose with no planned increase during the study.

Is Fecal Microbiota Transplantation (FMT) safe for humans?

FMT is generally considered safe and well-tolerated, especially for treating recurrent Clostridioides difficile infections. Most short-term risks are mild and related to delivery methods, but long-term side effects are not well-established. Serious adverse events have been linked to inadequate screening for multi-drug resistant organisms in donor stool. ^{1 2 3 4 5}

How is fecal microbiota transplant (FMT) different from other treatments for autism?

Fecal microbiota transplant (FMT) is unique because it involves transferring healthy gut bacteria from a donor to a patient to rebalance the gut microbiome, which may improve behavioral symptoms in children with autism. Unlike traditional treatments that might focus on behavioral therapy or medication, FMT targets the gut-brain connection, offering a novel approach to managing autism spectrum disorder. ^{3 6 7 8 9}

What data supports the effectiveness of the treatment Fecal Microbiota Transplant for Autism?

Research suggests that Fecal Microbiota Transplant (FMT) may help improve behavioral symptoms in children with autism by rebalancing the gut microbiome. FMT has also been used effectively for other conditions like recurrent Clostridium difficile infection and shows potential for treating various diseases, including metabolic and neurological disorders. ^{3 8 10 11 12}

Published Research Related to This Trial

Fecal microbiota transplantation (FMT) is primarily used to treat gastrointestinal diseases caused by harmful microorganisms, but it is also being explored for conditions like metabolic syndrome, diabetes, cancer, and Parkinson's disease.

The review discusses the effects of FMT on weight gain, immune response, and various diseases, while also addressing potential side effects that recipients may experience.

Fecal microbiota transplantation in disease therapy. Antushevich, H.[2020]

Faecal microbiota transplantation (FMT) has proven effective for treating recurrent Clostridium difficile infections, with established protocols and donor stool banks in Denmark.

However, FMT is not recommended for routine use in treating inflammatory bowel disease or irritable bowel syndrome due to insufficient clinical trial data supporting its efficacy for these conditions.

Fecal microbiota transplantation (FMT) is an effective method for modifying the gut microbiome and has shown promise in treating various conditions, including Clostridiodes difficile infection (CDI) and other gastrointestinal and neurological disorders.

While FMT is currently approved for CDI in Taiwan, there is a growing interest in its potential applications for other diseases, particularly in children, where data is still limited.

Fecal microbiota transplantation (FMT) is a generally safe and well-tolerated procedure for treating recurrent Clostridioides difficile infections, even in high-risk patients, with most short-term risks being mild and related to delivery methods.

Recent concerns have emerged regarding serious adverse events linked to FMT products from stool banks that do not screen for multi-drug resistant organisms, highlighting the need for improved safety protocols.

Fecal Microbiota Transplantation: Is It Safe? Park, SY., Seo, GS.[2021]

Fecal microbiota transplantation (FMT) is highly effective for treating Clostridium difficile infection (CDI), with a 90% resolution of diarrhea reported in 867 patients across 33 studies, and a 94% resolution after repeated FMT in a randomized controlled trial with 16 participants.

FMT shows promise in treating ulcerative colitis, with remission rates varying from 0% to 68% in 106 patients, while its efficacy in Crohn's disease, chronic constipation, pouchitis, and irritable bowel syndrome remains inconclusive due to limited data.

Fecal microbiota transplantation as novel therapy in gastroenterology: A systematic review. Rossen, NG., MacDonald, JK., de Vries, EM., et al.[2022]

Fecal microbiota transplantation (FMT) has a reported adverse event (AE) rate of 39.3%, primarily involving mild and self-limiting issues like abdominal pain and diarrhea, based on a meta-analysis of 9 high-quality studies involving 756 FMTs.

Serious adverse events (SAE) were relatively rare at 5.3%, with the most common being Clostridium difficile infection, indicating that while FMT is generally safe, monitoring and standardized reporting are essential for understanding its long-term safety.

Fecal microbiota transplantation (FMT) is recommended for treating recurrent Clostridium difficile infections and has shown benefits for various gastrointestinal disorders, but safety data is still limited due to the rapid adoption of the technique without extensive long-term studies.

Capsulized FMT therapy offers a promising solution for long-term maintenance and reduces the need for invasive procedures, indicating a shift towards safer and more tolerable methods of delivering FMT.

Fecal microbiota transplant (FMT) from tumor-bearing mice significantly improved cognitive function and short-term memory in Alzheimer's disease (AD) mice, indicating a potential therapeutic role for gut microbiota in cognitive impairment.

The FMT not only reduced Aβ plaque burden in the brain but also altered the gut microbiome composition, reversing specific microbial imbalances associated with AD, suggesting a complex interaction between gut health and cognitive function.

Fecal microbiota transplantation (FMT) has a total adverse event (AE) incidence rate of 28.5%, with abdominal discomfort being the most common AE reported in 19 studies, highlighting the need for careful monitoring during the procedure.

Serious adverse events (SAEs) occurred in 9.2% of patients, with a notable incidence of death (3.5%) and infections (2.5%), indicating that while FMT can be beneficial, it carries significant risks that require further investigation through high-quality randomized controlled trials.

Systematic Review: Adverse Events of Fecal Microbiota Transplantation. Wang, S., Xu, M., Wang, W., et al.[2023]

Fecal microbiota transplantation (FMT) is primarily studied for conditions like Clostridium difficile infection and inflammatory bowel disease, with 84% of the 85 reports focusing on these areas, but most studies (87%) were non-randomized controlled trials.

Important methodological details about FMT, such as donor eligibility criteria and stool collection methods, are often poorly reported, which hinders the ability to replicate studies and fully understand the safety and efficacy of FMT.
