Brief Summary:
The main objective of this exploratory 8-week pilot study is to evaluate the safety and efficacy of buspirone for the treatment of anxiety in youth (ages 6-17 years) with autism spectrum disorders. The study results will be used to generate hypotheses for a larger randomized-controlled trial with explicit hypotheses and sufficient statistical power.

Condition or disease Intervention/treatment Phase
Autism Spectrum Disorder Anxiety Drug: Buspirone Phase 2

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Pilot Study of Buspirone for the Treatment of Anxiety in Youth With Autism Spectrum Disorders
Estimated Study Start Date : March 2018
Estimated Primary Completion Date : March 2020
Estimated Study Completion Date : May 2020

Arm Intervention/treatment
Experimental: Buspirone
Buspirone tablets will be administered twice daily, and will be titrated to a maximum daily dose of 60mg for 8 weeks.
Drug: Buspirone
Children with autism spectrum disorders will receive buspirone treatment for eight weeks. Buspirone will be titrated to the maximum daily dose during the first four weeks of the trial (dose titration phase). Week 4 onwards, subjects will be maintained on maximum achieved dose until the end of the trial. During the titration phase, total dose will be increased by 10mg at each visit and by 5mg on the 4th day after each visit.



Primary Outcome Measures :
  1. Reduction in Child and Adolescent Symptom Inventory-5-Anxiety (CASI-Anx) Score [ Time Frame: Baseline to 8 Weeks ]
    The primary outcome measure of efficacy will be assessed by the reduction in anxiety symptom severity as measured by a change from baseline on the Child and Adolescent Symptom Inventory-5-Anxiety (CASI-Anx) scores. Responders are defined as those who demonstrate a >30% reduction on the CASI-Anx.
