A Study of Pregnenolone in the Treatment of Individuals With Autism

Not Recruiting

Trial ID: NCT01881737


This study will assess the tolerability and effectiveness of pregnenolone in the treatment of behavioral deficits in adults with autism. Pregnenolone is a naturally occurring hormone found in the body which has been shown to help with the function of nerve cells. It is also shown to modulate the activity of certain brain receptors implicated in autism. We hope to examine the tolerability of pregnenolone in adults with autism.
