Trial Overview

Trial Outcomes

Change in Ohio Autism Clinical Impressions Scale - Improvement (OACIS-I) Average Score From Baseline

The Ohio Autism Clinical Impressions Scale-Severity (OACIS-S) rates severity of symptoms in 10 categories: general level of autism, social interaction, aberrant and repetitive behavior, verbal and nonverbal communication, hyperactivity, anxiety, sensory sensitivities and restricted and narrow interests. Each category is rated from 1 (normal) to 7 (most severe). The OACIS-S was a reference at follow up visits when the OACIS-Improvement was compared to the OACIS-S, from 1 to 7: 4 was no change; 3 to 1 minimal to marked improvement and 5 to 7 minimal to marked worsening. The numerical score of the OACIS-S is independent and unrelated quantitatively to the OACIS-I. For analysis, the OACIS-I general score and subscale values were recoded, in which 4 (no change) was recoded as 0; 3 to 1 were recoded as +1 to +3 to denote improvement, and 5 to 7 were recoded as -1 to -3 for worsening. (NCT02561481)
Timeframe: 7 weeks, 15 weeks, 22 weeks, 30 weeks, 36 weeks

Change in Total Aberrant Behavior Checklist Score From Baseline

Aberrant Behavior Checklist (ABC) is a 58 item scale that primarily evaluates how aberrant or abnormal a patient's daily behaviors are. The items evaluate behaviors as they pertain to irritability, lethargy/social withdrawal, stereotypic behavior, hyperactivity/noncompliance, and inappropriate speech. Each item is scored on a scale of 0 to 3, with 0 being better outcome and 3 being worse outcome. The score from each item is added up to calculate a total score. This outcome describes change in total ABC score from baseline at each follow up visit. The scores from all items are added to calculate a total score (0 to 174). This outcome describes change in total ABC score from baseline at each follow up visit. (NCT02561481)
Timeframe: 7 weeks, 15 weeks, 22 weeks, 30 weeks, 36 weeks

Change in Total SRS-2 Score From Baseline

The Social Responsiveness Scale-2 (SRS-2) is a 65-item scale that measures total scores as well as subscales: four social behaviors (awareness, cognition, communication and motivation) and autistic mannerisms. Each item is rated from 1 to 4 (not true to almost always true) on worksheets that are blinded to the rater with respect to values. Total and subscale scores are calculated as raw scores and can be converted to T-scores. Raw scores (range 0-180) are reported here (unadjusted for general population, since all children had ASD). Higher or lower values at follow up visits compared to baseline indicated worsening or improvement, respectively. (NCT02561481)
Timeframe: 7 weeks, 15 weeks, 22 weeks, 30 weeks, 36 weeks

Dithiocarbamate Plasma Concentration Detected by Cyclocondensation at Each Visit

Sulforaphane (and other isothiocyanates, ITC) are conjugated by glutathione (GSH) which then undergoes further enzymatic modifications to give rise sequentially to the cysteinylglycine-, cysteine- and N-acetylcysteine-ITC conjugates, all of which are dithiocarbamates (DTC) and are detected in the cyclocondensation reaction-HPLC assay.
