Active clinical trials for "Autistic Disorder"

The purpose of this study is to evaluate the long-term safety and tolerability of memantine in the treatment of autism in pediatric patients.

Evaluate the efficacy of one infusion of stem cells from autologous umbilical cord blood in patients with autism over six months after infusion as measured by changes in expressive and receptive language. Also demonstrate improved behavior, learning, and changes in Serum tumor necrosis factor alpha (TNF-α), tumor necrosis factor beta (TNF-β), interleukin 1-alpha (IL-1α), interleukin 1-beta (IL-1β), interleukin 6 (IL-6), interleukin 10 (IL-10), and interleukin 13 (IL-13).

The purpose of this study is to determine the effectiveness of D-cycloserine for improving social impairment in child with pervasive developmental disorders (PDD).

Primary: to investigate tolerability of interventional high dose Vitamin D3 supplementation, titrated to reach serum levels near the high end of the reference range (30-100 ng/ml), in vitamin D deficient pediatric Autism Spectrum Disorder (ASD) patients. The study will determine if initial safety and effect estimates predict that a double blind randomized control trial (RCT) with a larger set of patients will be worthwhile in the localization of this treatment aimed at improving the symptoms of ASDs. Exploratory: to determine efficacy of high dose D3 replacement for improvement in the core symptoms of autism, including sociability, eye contact, anger outbursts, stimming behavior, and sleep, as determined by parental and clinical evaluation scales.

The purpose of this study is to evaluate the efficacy of risperidone compared with placebo in children and adolescents with irritability associated with autistic disorder.

The goal of this project is to collect information that will support a later clinical trial on the effectiveness of a specially adapted dental environment for children who have difficulty tolerating oral care in the dental clinic. We hypothesize that adapting the sensory environment in the dental office by modifying the sounds, sights, smells and tactile experiences will result in decreased anxiety, increased cooperation, and fewer behavior problems for children with Autism Spectrum Disorders, and to a lesser extent for typically developing children especially those who have dental anxieties. This has the potential contribute to increased child comfort as well as safer, more efficient, and less costly treatment for a large population, as potentially more than one-fourth of all children may benefit from a sensory adapted dental environment.

Allogeneic (not from the subject) human umbilical cord tissue-derived stem cells administered intravenously (IV) in a series of 4 infusions every 3 months over the course of one year is safe and will induce a therapeutic effect in autism patients.

This study is a prospective phase 1 single-center trial designed to determine the safety of a single intravenous infusion of autologous umbilical cord blood in children with Autism Spectrum Disorder (ASD) and assess the feasibility of various outcome measures to determine which measure(s) can be used as primary and secondary endpoints for a future randomized phase 2 clinical trial. All subjects will receive infusion of cord blood cells at baseline with follow up assessments at 6 and 12 months.

A multi-site randomized study of intensive treatment for toddlers with autism involving a three-site collaborative network plus a data coordinating center to evaluate the effects of intervention intensity and intervention style delivered for 12 months, on the progress of very young children with ASD ages 12-30 months old and their families, and the effect of children's developmental rates and autism severity on their response to intervention.

The purpose of this research study is to learn about the effects of supplemental intranasal oxytocin as a treatment for improving social difficulties in children and adolescents with autism. This study will also provide additional information about the safety and tolerability of intranasal oxytocin. Investigators expect oxytocin will increase social motivation, improving daily living skills and quality of life.
