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 hypothesis for a larger randomized controlled clinical trials with explicit hypotheses and sufficient statistical power.
Autism Spectrum Disorders
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||An Open-label Trial of Buspirone for the Treatment of Anxiety in Youth With Autism Spectrum Disorders
Primary Outcome Measures:
- Reduction in Pediatric Anxiety Rating Scale (PARS) score [ Time Frame: Baseline to 8 weeks ] [ Designated as safety issue: No ]
Primary outcome measure of efficacy will be assessed by reduction in anxiety symptom severity as measured by change from baseline. Responders are defined as >/=30% reduction in PARS score.
- Clinical Global Impression-Anxiety (CGI-Anxiety) Improvement Score [ Time Frame: Baseline to 8 weeks ] [ Designated as safety issue: No ]
Primary outcome measure of efficacy will be assessed by reduction in anxiety symptom severity as measured by Clinical Global Impression-Anxiety (CGI-Anxiety). Responders are defined as a score of </=2 on the improvement sub scale.

Buspirone administered in tablets twice daily 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 (dose maintenance pahe). During the titration phase, total dose will be increased by 10mg at each visit and by 5mg on the 4th day after each visit.
|Ages Eligible for Study:
||6 Years to 17 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:

- History of renal or hepatic impairment
- Clinically unstable psychiatric conditions or judged to be at serious suicidal risk
- Current diagnosis of schizophrenia
- History of substance use (except nicotine or caffeine) within past 3 months or urine drug screen positive for substances of abuse
- Current treatment with medication with primary central nervous system activity (as specified in the Concomitant Medication section of the protocol)
- A non-responder or history of intolerance to buspirone, after treatment at an adequate dose and duration as determined by the clinician
- Subjects currently taking monoamine oxidase inhibitors (MAOI) and/or CYP3A4 inducers or inhibitors including nefazodone, diltiazem, verapamil, erythromaycin, itraconazole, or rifampin.
