Brief Summary:
The purpose of this study is to determine whether CM-AT is effective in treating the core symptoms of autism.

Condition or disease Intervention/treatment Phase
Autism Drug: CM-AT Phase 3

Detailed Description:
Autism is currently a significant cause of disability in the pediatric population. CM-AT is based upon the observation that many children with autism do not digest protein. CM-AT is a proprietary enzyme that is designed as a powder taken three times a day. It is formulated to be released in the small intestine to enhance protein digestion thus increasing the availability of essential amino acids.
