Recruiting studies
- NCT05396352Recruiting
Study brain-task skills in autism using brain stimulation
This study looks at how different brain regions work in people with autism and in neurotypical adults using thinking tasks, MRI scans, and a noninvasive brain stimulation called tDCS. It may help researchers better understand social and executive thinking—how you plan and manage tasks.

This study looks at an “early diagnostic response” approach for toddlers who screen high-risk for autism. It aims to help families get timely follow-up and evaluation based on screening results.
Atlanta, GeorgiaAges 1.3 years–3 years - NCT05480826Recruiting
Family genetic study for mood, thinking, and autism conditions
This study looks at genetic changes found in people with conditions like bipolar disorder, schizophrenia, depression, or autism, and compares how those genetic differences may function. It may help researchers understand the causes of these conditions using information from patients and their relatives.
CréteilAges 18 years+ - NCT05501678RecruitingPhase 2
Diphenhydramine to help sleep in autistic children
This Phase 2 study tests whether diphenhydramine improves sleep in children with autism who have significant sleep problems. It requires sleep monitoring (watch data and sleep testing) and checking for side effects to see if the treatment is safe and helpful.
Stanford, CaliforniaAges 8–17 - NCT05512637Recruiting
Check for autism and other development issues in sibling children
This study screens brothers and sisters of children with autism to see if they may have neurodevelopmental (brain-and-development) concerns. It could help families catch issues earlier and connect to support sooner.
MontpellierAges 2–16 - NCT05520632Recruiting
Test sounds and hearing responses in young children with autism
This study checks how children’s brains and bodies respond to sounds using a hearing test called BAEP. It compares children with autism to other children with typical development to learn whether sound processing differs.
PortoAges 3–6 - NCT05540574RecruitingPhase 2
Zolpidem for sleep problems in autistic children
This Phase 2 study tests zolpidem (a sleep medicine) to help children with autism sleep better. It will check sleep changes using sleep testing and to confirm zolpidem is safe for this age group.
Stanford, CaliforniaAges 8–17 - NCT05546554RecruitingPhase 2
Suvorexant for sleep problems in teens with autism
This Phase 2 study tests whether suvorexant helps improve sleep in children and teens with autism who have significant sleep trouble. It may help reduce behaviors related to poor sleep by changing how the brain promotes sleep.
Stanford, CaliforniaAges 13–17 - NCT05584059Recruiting
Parent coaching for Hong Kong families of special health needs children
This trial tests a parent coaching programme to help parents of children with special health needs in Hong Kong. You may be invited if you answer screening questions and your child’s needs fit specific types that last at least 12 months.
Hong KongAges 21 years+ - NCT05590715Recruiting
Study of autism details using health records
This observational study looks at different groups of people with autism spectrum disorder (ASD) using existing medical records and caregiver reports. It may help researchers better understand what different autistic subgroups need, without giving an experimental treatment.
Phoenix, ArizonaAges 12–65 - NCT05600946Recruiting
Study of body differences in creatine transporter deficiency
This study looks at physical and body features in people with creatine transporter deficiency caused by a specific gene change (SLC6A8). It may help doctors better understand the condition and how it shows up, which can improve future care.
Bethesda, MarylandAges 2–40 - NCT05673096Recruiting
PACT therapy for young autistic children and their parents
This trial studies a structured communication therapy program (PACT) for children ages 2–6 who have autism. It aims to improve how children communicate and how families can support communication at home.
AabenraaAges 2–6 - NCT05681923Recruiting
Pregnancy study tracking how brain development risk may run in families
This study follows pregnant parents and their child to understand what factors influence early brain and development. It compares families with an autistic sibling (higher risk) to families without (lower risk) to spot patterns that may help future care.
MontpellierAges Any age - NCT05691283Recruiting
Brain stimulation study for children with autism
This study tests whether a noninvasive brain stimulation technique (tDCS placed on the scalp) may help children and teens with autism. It will compare outcomes before and after the stimulation sessions to see if it is safe and potentially beneficial.
Dalls, TexasAges 5–21 - NCT05698589Recruiting
Therapy program to reduce self-stigma in mental health
This study looks at how a program may help people with long-term mental health conditions feel less shame about their diagnosis (self-stigma). It is meant for adults who are stable enough to participate and who speak French.
BordeauxAges 18 years+ - NCT05699928Recruiting
Testing how well pediatricians spot autism in young children
This study compares an early autism opinion made by a community general pediatrician with a more detailed team assessment. It may help improve how families get autism evaluations sooner and more accurately.
Toronto, OntarioAges birth–5.3 years - NCT05726708Recruiting
E-learning coaching for parents of young children with autism
This study tests an online (e-learning) coaching program for parents of young children with autism, delivered in French. It aims to help parents learn strategies and support their child during early childhood.
LausanneAges 2–4 - NCT05750095Recruiting
Parenting support program for children with autism
This trial tests parenting programs designed for parents of young children with autism (ages 2–6). It may help you learn practical ways to support your child and your family day to day.
BergenAges 2–6 - NCT05754073RecruitingPhase 2
Oxytocin to improve bone health in children with autism
This Phase 2 study tests whether oxytocin can help improve bone health in children and teens with autism spectrum disorder. It also checks safety by monitoring symptoms and doing blood tests and imaging.
Boston, MassachusettsAges 6–18 - NCT05780853Recruiting
Game-based testing for young children’s learning and communication
This trial uses a simple, game-like assessment to better understand how young children develop and learn. It may help by creating or improving tools that track development and identify needs earlier.
LondonAges 3–8 - NCT05799599Recruiting
Peer support for preschoolers with autism
This trial looks at whether helping preschoolers with autism through structured peer interactions improves their communication and play. It may help if your child has limited spoken language and uses (or is starting) a speech-generating device.

Studying autism and typical brain/sensory patterns in people 12–40
This study looks at differences in “sensory” (how you experience sounds, touch, and other sensations) between people with autism and people without autism. The results may help researchers understand autism better and improve support in the future.
TaipeiAges 1.5 years+ - NCT05830591Recruiting
Gut microbiome study in autism in children

Common questions
- Are there clinical trials for autism spectrum disorder?
- Yes. Clin2 currently lists 331 recruiting autism spectrum disorder studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a autism spectrum disorder trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a autism spectrum disorder trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
