Propranolol for Autism
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine if propranolol, a type of beta-blocker, can reduce challenging behaviors such as aggression and self-injury in individuals with Autism Spectrum Disorder. Participants will be randomly assigned to one of two groups: one receiving propranolol and the other receiving a placebo (a look-alike pill with no active drug) for 12 weeks. Afterward, all participants will have the opportunity to try propranolol for an additional 12 weeks. This trial may suit individuals diagnosed with autism who experience severe behaviors impacting their daily lives, such as frequent aggression or self-injury. As a Phase 2 trial, the research focuses on assessing propranolol's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
Yes, you may need to stop taking certain medications. The trial excludes participants who are currently using specific medications like calcium channel blockers, ACE inhibitors, and antidepressants, among others. It's important to discuss your current medications with the study team to see if they are allowed.
Is there any evidence suggesting that propranolol is likely to be safe for humans?
Research has shown that propranolol can be safely administered to individuals with Autism Spectrum Disorder (ASD) to help manage difficult behaviors. Studies have found that high doses of propranolol are usually well-tolerated, with few heart-related side effects, provided there is careful monitoring. The FDA has already approved propranolol for other uses, indicating a certain level of safety. However, each person's experience may vary, so maintaining communication with the healthcare team is important to manage any side effects effectively.12345
Why do researchers think this study treatment might be promising for autism?
Unlike the standard treatments for autism, which often focus on behavioral therapies or medications like antipsychotics and stimulants, propranolol offers a unique approach by targeting the body's stress response. Propranolol is a beta-blocker that works by damping down the effects of adrenaline, which might help reduce anxiety and improve social functioning in individuals with autism. Researchers are excited about this treatment because it represents a novel mechanism of action, which could potentially address certain symptoms of autism more effectively than current options.
What evidence suggests that propranolol might be an effective treatment for autism?
Research shows that propranolol, which participants in this trial may receive, might help reduce difficult behaviors in people with Autism Spectrum Disorder (ASD). Earlier studies found that propranolol lowered aggressive symptoms by 50% and challenging behaviors by 37%. Commonly used for high blood pressure, this medication is believed to enhance brain function and provide cognitive and social benefits for those with ASD. Early evidence suggests that high doses can be safe with close monitoring. Overall, propranolol appears promising for managing severe aggression and behaviors associated with autism.678910

Are You a Good Fit for This Trial?
This trial is for adolescents and adults aged 12-40 with Autism Spectrum Disorder who exhibit severe behaviors like aggression or self-injury. They must have a study partner to report on their behavior, be able to swallow capsules, and meet certain health criteria including heart rate and blood pressure. Women of childbearing age must use effective contraception.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Propranolol
Trial Overview
The study tests if propranolol can reduce challenging behaviors in those with Autism over 12 weeks compared to a placebo. Afterward, all participants can choose to take propranolol for another 12 weeks.
How Is the Trial Designed?
2
Treatment groups
Experimental Treatment
Placebo Group
Propranolol, oral, starting at 30 mg/day (10 mg TID), titrated weekly based on tolerability to a maximum of 600 mg/day (200 mg TID) by Week 8. Participants will remain on their highest tolerated dose for an additional 4 weeks.
Participants will receive oral placebo tablets matched in appearance and dosing schedule to Propranolol. The dose will be titrated weekly in parallel with the experimental arm, and participants will remain on the highest tolerated dose for an additional 4 weeks.
