New Treatments & Clinical Trials for Autism Spectrum Disorder

Autism spectrum disorder affects roughly 1 in 36 children in the United States. There's no medication that treats the core features of autism — differences in social communication and restricted or repetitive behaviors — but some drugs address co-occurring conditions like anxiety, attention problems, or irritability. Most autism research focuses on early intervention, behavioral supports, and understanding the underlying biology.

What's actually going on in research

Trials are testing drugs that target specific brain pathways implicated in autism, including oxytocin, vasopressin receptor modulators, and drugs affecting GABA or glutamate signaling. Some studies examine repurposed medications like bumetanide or balovaptan. Researchers are also studying behavioral interventions, digital tools for early screening, and treatments for co-occurring sleep problems, GI symptoms, and seizures.

What to know before you search

Eligibility often depends on age, autism diagnosis confirmation, severity of symptoms, presence of co-occurring conditions, and whether someone is taking other medications.

What types of trials are currently open

• Drug trials — Testing medications that target brain pathways involved in social behavior, communication, or sensory processing.
• Behavioral intervention trials — Testing therapies like applied behavior analysis, parent-mediated interventions, or social skills training, often in young children.
• Co-occurring condition trials — Testing treatments for anxiety, sleep problems, attention difficulties, or irritability that often accompany autism.
• Digital and device trials — Testing apps, wearable devices, or virtual reality tools for early screening, tracking behaviors, or delivering therapy remotely.
• Observational studies — Following people with autism over time to understand how symptoms change, what predicts outcomes, and how different interventions work in the real world.
