Recruiting studies in California
- NCT07214545Recruiting
Nerve stimulation for kids with autism and ADHD
This trial tests a device that gently stimulates a nerve in the face to reduce difficult symptoms in children who have both autism and ADHD. It may help if your child is already on stable medications and can complete the study activities.
San Francisco, CaliforniaAges 7–14 - NCT07276750Recruiting
Coaching for school staff who support autistic children

N-acetylcysteine for autism behaviors in children
This trial studies whether N-acetylcysteine, a medicine taken by mouth, can improve autism-related restricted and repetitive behaviors in children. It looks at children who are showing at least moderate severity in these behaviors and may involve brain testing for safety reasons.
Palo Alto, CaliforniaAges 3–12 - NCT05494398Enrolling by invitationPhase 2/Phase 3
Testing N-acetylcysteine for autism symptoms
This study looks at whether N-acetylcysteine (NAC), a supplement/medication, can help autism-related symptoms by trying to target brain chemistry. You may be able to join if you previously took part in a related NAC study and can keep your usual medications steady.
Stanford, CaliforniaAges 3–13 - NCT04278898RecruitingPhase 2
N-acetylcysteine to reduce repetitive behaviors in children with autism
This Phase 2 study tests whether a single dose of N-acetylcysteine can improve “restricted and repetitive behaviors” in children with autism. It’s meant for kids who are stable and still in early puberty stages.
Stanford, CaliforniaAges 3–12 - NCT05987774Recruiting
AI program to improve social conversation skills in autism

Stanford, CaliforniaAges 3–35 - NCT05185128Recruiting
Social skills training and brain imaging in teens with autism
This study looks at how social thinking and social skills training affect the brain in teens with autism, compared with teens with other severe mental health conditions and typically developing teens. It may help researchers understand what drives social difficulties and what could improve social functioning.
Loma Linda, CaliforniaAges 12–18 - NCT05268796RecruitingPhase 2/Phase 3
Telehealth or in-home parent training for kids with autism
This study compares two ways of helping parents manage challenging behaviors in young children with autism: coaching by video (telehealth) or coaching in the home. It may help reduce self-injury or aggression by teaching caregivers practical behavior strategies over 12 weeks.
Stanford, CaliforniaAges 2–7 - NCT06651086Recruiting
Executive functioning help for children in therapy
This study tests a new way to help children with executive functioning challenges (like planning and staying organized) in therapy. It's for kids ages 6-12, with or without autism, who are getting therapy at publicly funded clinics.
San Diego, CaliforniaAges 6–99 - NCT06783101Recruiting
Smart Inhaler for Teens with Intellectual Disabilities and Asthma
This study tests a 'smart' inhaler that tracks when and how your child uses their asthma medicine. The goal is to help teens with intellectual or developmental disabilities manage asthma better at home.
Los Angeles, CaliforniaAges 10–17 - NCT06291233Enrolling by invitation
Interview training for autistic adults seeking jobs
This study helps autistic adults who are in job training programs find and keep jobs. You'll learn interview skills and get support to build your career.
San Diego, CaliforniaAges 16–26 - NCT03380078Enrolling by invitation
Training programs to better support kids with autism
This study tests an organized training plan meant to help mental health programs and schools support children with autism. It involves leaders, therapists/providers, and parents who complete brief surveys and assessments to see what improves care and services.
Westwood, Los Angeles, CaliforniaAges 18 years+ - NCT06920940Recruiting
Ketogenic diet for bipolar disorder in teens

Los Angeles, CaliforniaAges 12–21 - NCT06847165Recruiting
Trigeminal nerve stimulation for kids with prenatal alcohol exposure
This study tests a gentle, non-invasive nerve stimulation device to see if it can improve attention and behavior in children aged 8-12 who were exposed to alcohol before birth and have ADHD. If it helps, it could offer a new way to manage symptoms without medication.

What taking part in a autism spectrum disorder study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.

- Each study lists its eligibility rules — age, diagnosis, prior treatments. On every trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Do I have to live in California to take part?
- Not necessarily. These studies have a site in California, but eligibility is about your health, not your address — some people travel to take part, and a few studies reimburse travel. The study team can tell you what's required.
