Filter by:Study 22003, "An Open-Label, Flexible-Dose Evaluation of the Safety and Tolerability of STX209 for Treatment of Irritability in Subjects With Autism Spectrum Disorders(ASD)" currently is evaluating the efficacy of STX209 (R-baclofen) for management of typical problem behaviors, such as irritability and aggression, in subjects with ASD. This study (22007) will enter subjects who complete Study 22003 into a long-term, open-label study.The open-label extension protocol will provide necessary data on the long-term safety and tolerability of STX209 among subjects with ASD who receive treatment under conditions more closely reflective of their general medical care.
Previously it has been shown that Familial Encephalopathy with neuroserpin inclusion bodies (FENIB) patients develop abnormalities that partially overlap with Autism Spectrum disorders (ASD), confounded with additional features that could be explained by inclusion body formation not expected in subjects with inclusion body forming SERPINI1 mutations. There is no described human neuroserpin deficiency phenotype. The neuroserpin knockout mouse phenotype also suggests a possible overlap with autism. Neuroserpin could contribute directly at the synapse or through altered neuron migration during early development leading to the "underconnectivity" that underlies autism by potentially contributing to the excess of short connections and not enough long ones seen in autistic brains, possibly due to an imbalance in pruning of neurons and synapses early in life. It is thus proposed to sequence the neuroserpin gene in initially 20, and subsequently up to 100 idiopathic autistic patients selected as having the language impairment and perseveration endophenotypes.
This open-label research study will continue to monitor the safety of fluoxetine in children after their completion of a previous double-blind placebo controlled clinical study, with fluoxetine. The study will also look at the effect of fluoxetine on IQ (Intelligence Quotient) over an 18 month period.
There are two phases to the study. The first will examine serum copper and zinc levels and copper/zinc ratio in children (ages 3-8) who have autism and compare them to levels from same sex and age children who are developing typically. The hypothesis is that there is a significant difference in the copper/zinc ratio between young children who have autism and their typically developing peers. The second phase of the study will evaluate the effect of dietary supplementation using zinc and vitamin C for 16 weeks on selected symptoms of autism. Children with autism will be enrolled on the basis of copper/zinc ratios greater than 2.0, and as determined to be statistically higher than typically developing children. Measurements of serum copper, zinc and unbound copper will be obtained prior to, at the mid-point and end of the trial. Those children whose ratios have not fallen below 1.25, the top of the currently recognized range will have the zinc and vitamin C doses adjusted for the duration of the trial. Detailed evaluation of language skills, and a variety of behaviors will be evaluated prior to and after supplementation. The study will be placebo-controlled and double blind. Those children enrolled in the placebo arm will be offered a full trial of supplements at the end of the their participation in the study. The hypothesis to be tested is whether correction of elevated copper to zinc ratios in children with autism can be accomplished by oral supplementation with zinc and vitamin C and if these children show measurable and significant changes in receptive or expressive language or behavioral parameters associated with autism.
The aim of the study is to localise brain regions involved in objects recognition, in planification and adjustment of grasping, in prehension with and without eye control. The study is conducted in normal and autistic adults. We hypothesize different activations in these two populations.
The purpose of the study is to determine the effect of multiple doses of secretin on autism.
