Clinical Trial Summary

The aim of this study is to investigate if taking a supplement called Glutathione by mouth is safe and practical for children and teenagers with Autism Spectrum Disorder (ASD). The researchers plan to involve 24 individuals with ASD and give them oral Glutathione for 12 weeks.

Description:

The goal of the proposed study is to evaluate the safety and feasibility of oral Glutathione in children and adolescents who have Autism Spectrum Disorder. Twenty-four subjects with ASD will receive 12 weeks of oral Glutathione reduced. The hypothesis to be tested is that: Oral Glutathione will be effective in increasing the blood level of Glutathione, which may help to decrease some problem behaviors and irritability in this particular ASD population. The second aim of this study is to evaluate the tolerability of oral Glutathione. The proposed study may provide needed data for future studies aimed at the treatment of aggressive behaviors that can be seen in this patient population.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Change in Parent-Rated Anxiety Scale for Autism Spectrum Disorder (PRAS-ASD)	The PRAS-ASD is a reliable and valid measure that can be used to assess severity of anxiety in youth with ASD and evaluate change with treatment. It is a 25-item Parent-Rated Anxiety Scale for ASD (PRAS-ASD) designed to measure anxiety symptoms in children with ASD.	At a baseline and end of the trial (12 weeks)
Other	Change in Clinical Global Impression Scale	The CGI was developed for use in NIMH-sponsored clinical trials to provide a brief, stand-alone assessment of the clinician's view of the patient's global functioning prior to and after initiating a study medication. CGI-C scores range from 1 (very much improved) through to 7 (very much worse).	At baseline and the end of the trial (12 weeks)
Primary	Aberrant Child Checklist, looking at change in the subscale of the ABC	The Aberrant Behavior Checklist (ABC) is a scale designed to measure psychiatric symptoms and behavioral disturbance exhibited by individuals with IDD across 5 domains: Irritability, Agitation, & Crying; Lethargy/Social Withdrawal; Stereotypic Behavior; Hyperactivity/Noncompliance. he subscales and the respective number of items are as follows: (a) Irritability (15 items), (b) Social Withdrawal (16 items), (c) Stereotypic Behavior (7 items), (d) Hyperactivity/Noncompliance (16 items), and (e) Inappropriate Speech (4 items). The score is intended to check baseline and monitor changes. There is no cutoff as the study relied on diagnosis based on Autism Diagnostic Observation Schedule ADOS. Change is being assessed including monitoring for any worsening of symptoms reported in the subscales.	This will be checked at 4 weeks, 8 and 12 weeks (total of 3 measurements)
Secondary	Change in Social responsiveness Scale	The SRS-2 identifies social impairment associated with ASD and quantifies its severity. Sensitive enough to detect even subtle symptoms but specific enough to differentiate clinical groups. the SRS-2 identifies social impairment associated with autism spectrum disorders (ASDs) and quantifies its severity. It's sensitive enough to detect even subtle symptoms, yet specific enough to differentiate clinical groups, both within the autism spectrum and between ASD and other disorders. The study would not require a specific score.	At baseline and end of the trial (12 weeks)
Secondary	Change in Vineland Adaptive Behavior Scales	Questionnaire is assessment of individuals with intellectual, developmental (including autism), and other disabilities. Domains assessed include communication, daily living skills, socialization, motor skills, and maladaptive behaviors.	At baseline and end of the trial (12 weeks)
