Autism Spectrum Disorder Clinical Trials

The primary objective of this study is to evaluate the cognitive and behavioral effects of liquid leucovorin calcium on young children with autism spectrum disorder (ASD) and determine whether it improves language as well as the core and associated symptoms of ASD. The investigators will enroll 80 children across two sites, between the ages of 2.5 and 5 years, with confirmed ASD and known language delays or impairments. Participation will last approximately 26 weeks from screening to end of treatment. Read Less

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin on bone health in children with autism spectrum disorder, ages 6-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (30 IU, 2 times daily) for 12 months in the double-blind phase, followed by a 6-month open label phase during which all study subjects will receive intranasal oxytocin (30 IU, 2 times daily). Study visits include screening to determine eligibility, followed by study visits at baseline, week 2, and months 6, 12, 18 and phone calls every two weeks for the first two months and monthly thereafter for the duration of the study. Study assessments include history and physical examinations, anthropometric measurements, electrocardiogram (EKG), adverse event monitoring, laboratory tests for chemistries, hormones and biomarkers for bone metabolism, questionnaires regarding diet and exercise, and imaging to assess body composition, bone density and structure.

The goal of this clinical trial is to learn about the journey of families after their child's diagnosis of autism and to help parents understand autism and get the right treatments for their child. This study is for parents of children just diagnosed with autism who are: Age greater than 1 and up to 5 years old; Hispanic/Latino OR Black/African-American OR have Medi-Cal as primary health insurance; AND Live in one of the following counties in California (Alameda, Contra Costa, Marin, Monterey, Napa, San Benito, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, or Sonoma). The main questions it aims to answer are: Whether parent coaching through Project AFECT leads to decreased parental stress and increased parental confidence; Whether family navigation through Project AFECT leads to increased number of referrals to early intervention and educational services and reduced wait times to autism treatments; Whether children whose parents receive Project AFECT intervention show increased language skills compared to children whose parents did not receive intervention. Participants will be asked to: Complete surveys at enrollment and 3 and 6 months later. Work with Project AFECT Coach. Researchers will compare control and intervention groups to see if Project AFECT leads to improved parent and child outcomes. Read Less

The goal of this clinical trial is to assess the effect of short-term (3 days/week for 2 weeks) Virtual Reality (VR) active video gaming intervention on static and dynamic balance, versus traditional balance training exercises, in youth with ASD. The participants in the intervention group will engage in VR active video gaming using the Nintendo Switch Sports under supervision via Zoom for 6 sessions occurring over 2 weeks, from their home. While, the participants in the control group will engage in standard physical therapy exercises for balance and walking under supervision via Zoom, for 6 sessions occurring over 2 weeks, from their home. Their balance and walking will be assessed 3 times, 3-5 days before the intervention, 3-5 days after the intervention and 4-weeks after the intervention. Participants static balance will be assessed by standing on pressure mat, under 2 conditions, eyes open and eyes closed for 30 seconds each. The Pediatric Berg's balance Scale (PBS), a 14-point scale containing everyday activities, will be used as a clinical measure for assessing the static and dynamic balance. 13-infra-red camera motion capture system, Qualisys, will be used for assessing the walking. The difference in the balance and walking parameters will be assessed and compared. Read Less

This study is a 12-week randomized-controlled trial of memantine hydrochloride (Namenda) for the treatment of social impairment in youth with Non-Verbal Learning Disorder, High-Functioning Autism Spectrum Disorder, and related conditions. Eligible participants will be males and females ages 8-18. This study consists of up to 6 visits to Massachusetts General Hospital. Read Less

The purpose of this study is to examine the effect of diphenhydramine on sleep in children and adolescents with Autism Spectrum Disorder (ASD). Diphenhydramine is an anti-histaminergic agent with strong hypnotic properties. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of diphenhydramine on sleep physiology as assessed by polysomnography (PSG), actigraphy, circadian rhythm, and clinical measures.

The purpose of this study is to examine the effect of zolpidem on sleep in children and adolescents with Autism Spectrum Disorder (ASD). Zolpidem is a nonbenzodiazepine GABAa receptor agonist drug that acts as a hypnotic. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of zolpidem on sleep physiology as assessed by polysomnography (PSG), actigraphy, circadian rhythm, and clinical measures.

The purpose of this study is to examine the effect of suvorexant on sleep in children and adolescents with Autism Spectrum Disorder (ASD). Suvorexant is a selective, dual orexin receptor antagonist (DORA) used for the treatment of sleep onset difficulties and/or sleep maintenance. To accomplish this, the investigators will use a randomized double-blind placebo-controlled crossover 8-week study design to examine the effect of suvorexant on sleep physiology as assessed by polysomnography (PSG), actigraphy, circadian rhythm, and clinical measures.

Background: Creatine transporter deficiency (CTD) is a genetic disorder that mainly affects the brain in males. CTD causes intellectual disability that can be mild to severe. People with CTD may have seizures and behavioral issues. They may have slow growth and tire easily. CTD may sometimes be confused with autism or other disorders. Better diagnostics are needed. The study team in an NIH study noted that the faces of children with CTD can look similar. For this natural history study, an expert will examine photos of children with CTD. Any shared traits found might help to diagnose CTD. Objective: To look for shared facial features of children with CTD. Eligibility: Males aged 2 to 40 years old with CTD who were in study 17-CH-0020. Design: Some participants in study 17-CH-0020 had pictures taken of their faces. The NIH study team wants to share these photos with a colleague in Canada. This person is an expert at evaluating how genetic disorders affect people s bodies. Participant data collected during the study may also be sent to this expert. This data may include diagnostic images and results from lab tests. Some children did not have their pictures taken during study 17-CH-0020. Parents are asked to take pictures of these children and send them to the study team. These photos can be sent to a secure portal. The photos can also be taken in-person during a clinic visit. The photos may be printed in clinical study journals. But this is not required. Parents will be asked to sign a separate consent before the photos are published. Read Less
