Challenging Behavior clinical trials

Propranolol for Challenging Behaviors in Autism

Severe challenging behaviors such as aggression and self-injury can cause significant morbidity and decrease the quality of life for individuals with Autism Spectrum Disorders (ASD). There are only two medications (Risperdal and Abilify) rigorously studied and FDA-approved for the treatment of irritability in individuals with ASD. These medications are not always successful and have many short and long-term side effects. Well-designed studies demonstrating efficacy and safety of alternative medication treatment choices are needed. There is preliminary evidence that high-dose propranolol can be effective in individuals with ASD who display severe aggression and have not responded to antipsychotics or mood stabilizers. Concerns regarding the safety of high dose propranolol have limited its clinical application. Well-designed clinical trials demonstrating the efficacy and safety of high dose propranolol will have significant effects on clinical practice and improve the physical and behavioral quality of life for an underserved subset of individuals with ASD. This study will pilot the safety and efficacy of high dose propranolol. The investigators will randomly assign participants to either propranolol or to placebo later crossing each participant over to the other group. As propranolol can cause changes in blood pressure and heart function, each participant will complete initial comprehensive testing to monitor cardiac safety throughout the study. The investigators will be utilizing telemedicine and computer based telemetry to minimize the burden of office visits on the individual and family.
