Clinical Trial Summary

This is a Phase III, open label extension study evaluating the continued safety and efficacy of CM-AT in pediatric patients with autism with all levels of fecal chymotrypsin.


Description:

Autism is clearly a significant cause of disability in the pediatric population. Treatment is based on the observation that many children with autism do not digest protein. CM-AT is a proprietary enzyme that is designed as a granulated powder taken three times daily.
