USE OF FLUOXETINE TO TREAT AUTISM SPECTRUM DISORDER

Autism spectrum disorder (ASD) is a collection of development disorders characterized by difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. In addition to social deficits, ASD can also result in intellectual delays, irritability, problems with motor coordination, and additional physical ailments including gastrointestinal issues. It is estimated that there are over 4M patients worldwide with ASD and the incidence rate is rising rapidly. The estimated lifetime healthcare and societal cost of ASD is $3.2MM per patient indicating a real need for effective ASD therapies. The therapeutic market for ASD is expected to grow to over $700MM by 2017. There are currently two FDA approved therapeutics for ASD (Risperdal® and Abilify®). However, they treat only the irritability component of ASD.

While the etiology of ASD is still unknown, there is evidence that some of the core characteristics of ASD, including repetitive behaviors, are due to an imbalance in the serotonin system. Dr. Hollander and colleagues validated the use of the selective serotonin-reuptake inhibitor fluoxetine to treat ASD in a pilot double-blind placebo controlled human proof-of-concept study. The outcome indicated treatment with fluoxetine reduced ASD-associated repetitive behaviors. Over 11 clinical trials of fluoxetine in autism have been conducted.
