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.

| Autism Spectrum Disorder (ASD) Gastro-Intestinal Disorder | Biological: FMT versus placebo | Phase 1 |
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.

- Primary Outcome Measures, safety and tolerability [ Time Frame: 24 weeks ]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.
- Secondary Outcome Measures, symptom improvement [ Time Frame: 24 weeks ]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.
