Recruiting studies in California
- NCT05301361Enrolling by invitationPhase 1
Test of brain testing during stimulant treatment for ADHD
This trial checks whether a “NIH Toolbox” set of child-friendly tests can detect changes when stimulant medicine is used for ADHD. It may help doctors better measure how well stimulant treatment is working in people with intellectual disability.
Sacramento, CaliforniaAges 6–24 - 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 - NCT03047369Recruiting
Myelin brain disorder research biobank for samples and data
This study collects brain-related medical information and biological samples to help researchers better understand leukodystrophies and other white-matter brain disorders. It may help future diagnosis and treatments by building a valuable “biobank” of patient data and samples.
Los Angeles, CaliforniaAges Any age - NCT05471232Recruiting
Genomic testing for youth mental health crises with IDD
This study looks at genetic (DNA) information to understand mental health crises in youth with intellectual and developmental disabilities. It may help doctors learn why these crises happen and improve how future families are supported.
San Diego, CaliforniaAges 7–17 - NCT06555965Recruiting
STXBP1 and SYNGAP1 natural history study
This study follows people with STXBP1 or SYNGAP1 gene changes over time to learn more about how these conditions affect the body and mind. It does not test a treatment but helps researchers understand the natural course of the disorder.
Palo Alto, CaliforniaAges Any age - NCT06829264Recruiting
Supported employment help for autistic young adults
This study tests whether a supported employment program helps autistic young adults ages 18 to 40 find and keep jobs. You'll get job coaching and support to help you succeed in the workplace.
Sacramento, CaliforniaAges 18–40 - NCT01403402Recruiting
Study of congenital muscle disease patients and their families
This trial collects health information from patients with certain inherited (genetic) muscle diseases and from their families. It may help researchers better understand the disease and improve care by learning what symptoms and treatments patients experience over time.
Lakewood, CaliforniaAges Any age - NCT05432349Recruiting
Rett syndrome genetic registry for MECP2 changes
This trial is a registry that collects health and genetic information from people with Rett syndrome. It may help researchers better understand how MECP2 loss-of-function changes lead to symptoms and how to support patients.
San Diego, CaliforniaAges birth–99 years - NCT07625579Recruiting
Collaboration for Down Syndrome Progress Research Study
This research study aims to better understand Down syndrome by collecting health information, family history, and sometimes brain imaging or sleep data from children and adults with Down syndrome and their families. The goal is to advance knowledge that could improve health and development for people with Down syndrome.

What taking part in a intellectual disability 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.

Common questions
- Are there intellectual disability clinical trials in California?
- Yes. We're currently tracking 9 recruiting intellectual disability studies with a site in California, each rewritten in plain language so you can see what it's testing and who it's for.
- How do I find out if I qualify for a intellectual disability study in California?
- 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.
- Does it cost anything to join a intellectual disability trial?
- Using Clin2 is always free. Many trials cover the study treatment and related visits; some reimburse travel. The study team explains exactly what's covered before you decide.
Not the right time?
New intellectual disability studies open in California regularly. Set up a health profile and we’ll quietly watch for studies that fit you and email you when one opens.
Clin2 helps you find and understand clinical trials and does not provide medical advice. Study data comes from ClinicalTrials.gov. Talk with your doctor about whether a specific trial is right for you.
