BURLINGTON, MA, USA I May 14, 2014 I Coronado Biosciences, Inc. (CNDO) today announced that it has initiated a Phase 2a clinical trial of TSO (Trichuris suis ova or CNDO-201) for the treatment of pediatric patients with autism spectrum disorder (ASD) at multiple centers in the United States.

“We are excited to begin this study,” said Dr. Lindsay A. Rosenwald, Chairman, President and CEO of Coronado. “Data from this study will greatly expand our understanding of TSO’s clinical usefulness in pediatric patients with ASD, an indication with a great unmet need in medicine today.”

The study is a randomized, double-blind, placebo-controlled crossover study designed to evaluate the safety and efficacy of TSO in pediatric patients with ASD. Approximately 20 ASD patients in the age range of 5 to 17 will be enrolled and randomized to receive either TSO or placebo once every 2 weeks, for 16 weeks, followed with a 4 week washout and the opposite treatment for 16 weeks. The primary endpoint for the study is Aberrant Behavior Checklist — Irritability subscale (ABC-I) and the key secondary endpoint is Children’s Yale-Brown Obsessive Compulsive Scale Modified for Pervasive Developmental Disorders (CYBOCS-PDD).

About Autism Spectrum Disorder

Autism spectrum disorder and autism are both general terms for a group of complex disorders of brain development. These disorders are characterized by three core symptoms: difficulties in social interaction, verbal and nonverbal communication and repetitive behaviors. Autism statistics from the U.S. Centers for Disease Control and Prevention identify approximately 1 in 68 American children as on the autism spectrum. Autism Speaks, the world’s leading autism science and advocacy organization, announced in March 2012 preliminary results of new research that estimates autism costs society $126 billion per year in the U.S.
