About this study

Official title: Dynamics of Gut Microbiomes in Autism Spectrum Disorder (ASD) Symptoms

The purpose of this study is to find out if transplant of fecal matter (stool), also known as fecal microbiota transplantation (FMT), from a healthy person into the intestines of children and young adults with Autism Spectrum Disorder (ASD).

For this study children between the ages of 5-17years will be recruited over 2 years. Children will be recruited who receive an ASD diagnosis using the gold-standard Autism Diagnosis Observation Schedule -2 (ADOS-2) using module 1, 2 or 3 (none, limited or no moderate expressive language). Children diagnosed with these modules of the ADOS-2 may be at greater risk for GI disorders and rigid-compulsive behaviors. Additional assessment of rigid-compulsive behaviors and social communication will be done using the Repetitive Behavioral Scales-Revised (RBS-R) and Social Responsiveness Scale-2 (SRS-2), respectively. KBIT (the Kaufman Brief Intelligence Test) is used at baseline to obtain patient IQ. Total evaluation time is approximately 90 minutes. Following baseline symptom evaluation, a medical exam will be performed to determine whether each child is expressing specific GI symptoms. In addition, parents will fill out the Questionnaire for Pediatric Gastrointestinal Symptoms- Rome III (QPGS-III). Once an ASD diagnosis is confirmed, FMT treatment will be initiated, which typically occurs within 4-6 weeks of the initial diagnosis. Half 50% of the children (n=5) will receive the equivalent of 50 g of stools from a healthy donor into the jejunum through upper endoscopy and the other 50% off children (n=5) will receive Saline solution as Placebo control through upper endoscopy.

Subjects will have a total of 5 visits within 24 weeks including phone call follow up on Day 7 after FMT.

Read the detailed description

Nearly 1 in 60 children are diagnosed with ASD, a dramatic increase from the start of the 21st century. Although most children with ASD exhibit core social communication deficits, very limited interests, repetitive behaviors and sensory problems, the severity of symptoms and how well each child responds to standard behavioral therapies can vary tremendously from patient to patient. This makes it difficult to enact effective interventions. Other variables also influence the outcomes for ASD patients, including age at first diagnosis, access to care, the quality of treatments and the expertise of interventionists.

Children with ASD also have medical disturbances, which affects their quality of life and compliance in intervention programs. For example, approximately 40 percent of children with ASD have gastrointestinal disturbances (GIDs). Genetics plays a substantial role in risk, but scientists also have determined that non-heritable factors can trigger the expression and severity of ASD symptoms. Clinical research studies from PI laboratories have focused on the gut-brain link that influences ASD symptoms, how a child functions and even responds to interventions .

The investigators hypothesize that children with ASD will tolerate single endoscopic delivery of fecal transplant therapy which will modify their gut microbial profile leading to reduction of repetitive and rigid-compulsive behaviors, based on the Repetitive Behavioral Scales-Revised (RBS-R). Secondary outcomes include improved score in social responsiveness scale and gastrointestinal symptoms . Investigators propose a phase I safety study for the use of FMT in children with Autism Spectrum Disorder.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Primary Outcome Measures, safety and tolerability

    The primary Outcome is safety of FMT and also it is measured by any symptom changes in obsessive/compulsive and repetitive behaviors using the RBS-R questionnaire.

    Measured: 24 weeks

Secondary outcomes (1)
  1. Secondary Outcome Measures, symptom improvement

    Secondary endpoints will include cognitive improvement using language use in a 10 minute interactive session, Social Responsiveness Scale-2. The SRS-2 is newly available (Western Psychological Services). It is a parent 65-item questionnaire that provides a continuous quantitative measure of three DSM domains, including social behavior, communication, and restricted and repetitive behaviors, normed in typically developing (T-score=50, sd=10) and ASD populations. The SRS-2 offers new DSM-5 subscales. The SRS is used in a variety of clinical and research settings. T-scores of 65 correlate highly with an ASD diagnosis, but do not substitute for the ADOS. Changes in SRS T-scores have been used as a measure of social behavior change over time.

    Measured: 24 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study of Autism Spectrum Disorder (ASD) and Gastro-Intestinal Disorder, run by Children's Hospital Los Angeles at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 2 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Outcome Measures, safety and tolerability (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03426826, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Nov 2023.
