|Condition or disease||Intervention/treatment||Phase|
|Autistic Disorder Pervasive Developmental Disorder||Drug: mecamylamine Drug: placebo||Phase 1|
This is a placebo-controlled pilot clinical trial of a nicotinic agent based on evidence that a disturbance occurs in nicotinic cholinergic transmission in the brain of autistic children. This pharmacotherapeutic trial will be conducted as a direct result of findings of a nicotinic receptor abnormality in autopsied brain tissue from individuals who suffered from autism. A pharmacological agent, mecamylamine, with specificity for the nicotinic receptors implicated in autism, will be tested in children with autism spectrum disorder. Twenty children who meet inclusion/exclusion criteria will be randomized in a 2:3 ratio to 14 weeks of either matched placebo (n=8) or mecamylamine (n=12). Children randomized to placebo who do not respond will be given the opportunity to enroll in a ten week open label extension.
The trial has been completed and published in J. of Child & Adolescent Psychopharmacology.

Experimental: Active Mecamylamine
There will be 12 children in this arm. These children will receive the active medication (mecamylamine).
The dosage is titrated at 6 weeks of .5mg, 2 weeks of 2.5 mg, and 6 weeks of 5.0 mg. One pill is taken once daily.
Other Name: Inversine
Placebo Comparator: Placebo
There will be 8 children in this arm. These children will receive placebo instead of the active medication.
One pill is taken once daily.
- The primary measure will be a global composite derived by calculating the z scores on each measure other than CGI from published norms (or from the baseline descriptives, then averaging the z scores of the various outcome measures for each individual.
