Safety and Efficacy Study in the Treatment of Intestinal Problems Associated With Autism

Phase 2

• Conditions: Autism; Autistic Disorder; Child Development Disorders, Pervasive; Gastrointestinal Diseases; Signs and Symptoms, Digestive

• Registration Number: NCT00110708
• Lead Sponsor: PediaMed Pharmaceuticals

Brief Summary

The purpose of this study is to determine if human immunoglobulin given by mouth twice a day is effective in treating the persistent gastrointestinal (GI) problems such as diarrhea, constipation, abdominal pain, and bloating, in children with autism.

Detailed Description

Autistic GI Dysfunction (AGID) is a term that describes a constellation of GI signs and symptoms often found in children with autistic disorder, including abdominal pain, constipation, chronic diarrhea, alternating constipation and diarrhea, gaseousness, bloating, and reflux.

The objective of this study is to assess the potential efficacy of oral immunoglobulin in reducing a wide range of GI symptoms in children and adolescents diagnosed with autistic disorder.
