Study Overview

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.

Arms & Interventions

Buspirone

Experimental

Buspirone tablets will be administered twice daily, and will be titrated to a maximum daily dose of 60mg for 8 weeks.

Intervention: Buspirone (Drug)

Outcomes

Primary Outcomes

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.

Secondary Outcomes

No secondary outcomes reported
