Milnacipran in Autism and the Functional Locus Coeruleus and Noradrenergic Model of Autism

Study Summary

Autism Spectrum Disorders (ASD) include Autistic disorder, Asperger's syndrome and Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS). These are developmental disorders beginning prior to three years of age. Recent Centers for Disease Control (CDC) estimates suggest that ASD affects up to 1 in 100 individuals and up to 1 in 50 boys. There are very substantial costs associated with caring for patients with ASD, and ASD has the highest Caregiver Burden Scores of any condition. There are three core symptom domains of ASD, including social deficits, repetitive behaviors and language deficits. Patients can also have associated symptoms of attentional deficits, disruptive behaviors and intellectual disability. There is currently no Food and Drug administration (FDA) approved treatment for the core symptoms of autism, but risperidone and aripiprazole have FDA approval for disruptive behaviors associated with autism. This is a 12 week randomized double blind placebo controlled trial of Milnacipran in adults with ASD or Aspergers Syndrome. Milnacipran is said to play a role in the activation and normalization of the locus coeruleus-noradrenergic system, of which is hypothesized to play a role in behavior adaptations and performance.

Primary Outcome

Change will be measured in each subject's score on the Conners Adults Attention Deficit Hyperactivity Disorder (ADHD) Rating Scale from baseline through study end (week 12).Higher values represent a worse outcome. The raw scores are converted to T-scores for each scale and sub-scale which are then compared against the mean. Higher values represent a worse outcome. A T-score of 50 is the mean of a relevant reference population. A T-score above 65 indicates a moderate to severe problem. For examp
