The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Autism-spectrum disorder with Gastrointestinal disorders (constipation, diarrhea, and/or abdominal pain). MTT involves a combination of 14 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using Miralax, followed by 5 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.

Childhood Autism Rating Scale (CARS-2)
A 15-item scale that can be used to both diagnose autism and ASD and to assess the overall severity of symptoms
Baseline (0-30 days prior to treatment) vs End of Treatment (Day 104)
Daily Stool Record (DSR)
Participants will report the number of abnormal events during a 14 day period. An event includes no bowel movement during 1 day, unusually hard stool (Bristol Stool Form type 1-2), unusually soft stool (Bristol Stool Form type 6-7), four or more bowel movements in 1 day, abdominal pain, or use of GI medication. The units are number of events regardless of type of event.
Screening (0-120 days prior to Baseline) vs Baseline (0-30 days prior to treatment) vs End of Treatment (Day 104)
Part 1: Blinded Treatment (15 weeks) Vancomycin, Miralax, Antacid, MTP-101P
Part 1: Blinded Treatment (15 weeks) Vancomycin, Miralax, Antacid, MTP-101P
MTP-101P is comprised of standardized dose of total fecal microbiota purified from the stool of healthy donors. Donors are carefully screened via health status questionnaires, physical examinations, reviews of comprehensive medical history, clinical laboratory evaluations, serologic and genomic tests for infectious diseases and metabolic health, and stool-related pathogen testing. The material from the donors is purified to remove the majority of non-bacterial material, washed, lyophilized, and provided to the patient in a sachet contained within a mixing bottle.

Part 1: Blinded Placebo (15 weeks) Placebo Vancomycin, Real Miralax, Real Antacid, Placebo MTP-101P
Part 1: Blinded Placebo (15 weeks) Placebo Vancomycin, Real Miralax, Real Antacid, Placebo MTP-101P
Oral vancomycin is an antibiotic used for treating C. difficile-associated diarrhea and staphylococcal-induced enterocolitis. Duration: 14 Days
Miralax is a common over-the-counter laxative and bowel cleanse
The antacid will be aluminum/magnesium hydroxide, 1x/day, 5 minutes before the MTP-101P. Each 5 ml consists of Aluminum Hydroxide - 200 mg, Magnesium Hydroxide - 200 mg, and Simethicone - 20 mg. If some participants cannot tolerate the aluminum/magnesium hydroxide, we will allow calcium carbonate alternatives equivalent in acid neutralizing capacity. Duration: 12 weeks
The same packaging will be used as for MTP-101P, but the sachets will contain a freeze-dried mixture of normal saline containing 10% Trehalose. Duration: 12 weeks
Same packaging and liquid carrier and flavoring used as for the oral vancomycin, but no vancomycin. Duration: 14 days
