The aim of this randomized controlled trial is to determine if a nutritional supplement containing broccoli sprout and seed extracts, a rich source of sulforaphane, is effective in reducing core symptoms of autism spectrum disorder (ASD). The study will also explore the safety and tolerability of a sulforaphane supplement in young men with ASD, as well as its effects on challenging neuropsychiatric symptoms that are commonly associated with ASD, such as hyperactivity, irritability, and repetitive movements.
Autism spectrum disorder (ASD) is a neurodevelopmental disorder affecting 1 in 68 children, including 1 in 42 boys, characterized by marked social communication impairment and restricted, repetitive behaviors and interests. Evidence-based pharmacological treatments available for the treatment of the defining symptoms of ASD are currently lacking.
While the etiology of ASD is not fully understood, the pathogenesis is hypothesized to involve cellular dysfunction, including increased oxidative stress, aberrant neuroinflammation, and reduced mitochondrial capacity, leading to synaptic dysfunction in at least a subset of individuals. Sulforaphane is a powerful upregulator of antioxidant response elements and heat shock proteins, which may lead to improved redox capacity, decreased inflammation, and improved mitochondrial functioning in individuals with ASD. A trial by Singh and colleagues (2014) provided preliminary evidence suggesting that sulforaphane derived from broccoli sprout extract can have beneficial effects for improving symptoms of autism.
In this study, young men ages 13-30 years old with moderate to severe autism spectrum disorder will be randomly assigned to receive either a sulforaphane supplement or placebo for a 12 week treatment treatment period, followed by a 4 week blinded discontinuation phase. The uncoated tablets each contain 125 mg broccoli seed extract and 50 mg broccoli sprout extract, corresponding to approximately 15 µmol sulforaphane per tablet. The dose will vary from 3-8 tablets daily depending upon the participant's weight. Matched placebo tablets contain only inert ingredients
A serum sample will be collected prior to starting treatment and at the end of the treatment phase to quantify sulforaphane metabolites. Clinical response will be assessed through clinician- and caregiver-rated measures of autism symptoms (Social Responsiveness Scale-2; Repetitive Behavior Scale- Revised), challenging symptoms commonly observed in individuals with developmental disabilities (Aberrant Behavior Checklist), and global severity of symptoms and improvement (Clinical Global Impression Scale). A blood sample will be collected at baseline and at the end of the treatment phase to check safety labs, and a saliva sample will be collected at baseline for a future study of genetic biomarkers associated with treatment response.

A T-score of 76 or higher is considered "severe". T-scores between 66 and 75 are considered as "moderate". T-scores between 60 and 65 are considered "mild". A T-score below 60 is considered typical. The theoretical range of a T-score is 10 to 90. The actual range of the SRS-2 in this study is 45 to 90. | Baseline |

| Primary | Social Responsiveness Scale-2 (SRS-2) Total Score at Week 4 | The Social Responsiveness Scale-2 (SRS-2) is a 65-item caregiver report that includes 5 subscales covering core symptom domains of ASD (Social Awareness, Social Cognition, Social Communication, Social Motivation, and Restricted Interests/ Repetitive Behaviors). The SRS-2 provides a T-score that is scaled such that the mean is 50 and the SD is 10. Higher scores indicate a higher presence and severity of autistic social impairment. A T-score of 76 or higher is considered "severe". T-scores between 66 and 75 are considered as "moderate". T-scores between 60 and 65 are considered "mild". A T-score below 60 is considered typical. The theoretical range of a T-score is 10 to 90. The actual range of the SRS-2 in this study is 45 to 90. | Posted | Least Squares Mean | Standard Error | T-score | Week 4 |
