A Pilot Study of Buspirone for the Treatment of Anxiety in Youth With Autism Spectrum Disorders
March 11, 2024 updated by: Tolga A Ceranoglu, Massachusetts General Hospital
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.

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.
|
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.

Measure Description |
Time Frame |
---|---|---|
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.
