This is a 6-week open trial to identify the optimal dosing of cannabidiol (CBD) in youth with autism spectrum disorder (ASD) and to identify primary and secondary outcomes for future controlled studies. This study will evaluate change in symptoms commonly associated with ASD, as evidence suggests that CBD may be effective in addressing difficulties such as irritability and anxiety, while maintaining a benign adverse effect (AE) profile in children and adolescents.
30 male and female participants with ASD between the ages of 7 and 17 years old will be recruited. Participants will have fluent speech and an estimated IQ greater than or equal to 80. Study intervention will be 98% pure CBD. The CBD will be Greenwich Biosciences, Inc.'s 100mg/mL oral solution, brand name EPIDIOLEX. A Bayesian optimal interval (BOIN) design will be used, such that participants will be assigned to cohorts of size 3 receiving doses of 3, 6, or 9 mg/kg/day, depending on the treatment response of participants in prior cohorts.

- Clinical Global Impression Scale -Improvement (CGI-I) [ Time Frame: 6 Weeks ]This is a 7-point scale measuring symptom change from baseline.
- Brief Observation of Social Communication - Change (BOSCC) [ Time Frame: Baseline, Week 6 ]The BOSCC is an observational, play-based measure of treatment response for core ASD symptoms. Each item is coded using a decision tree, which relates to information about specific behaviors. BOSCC coding is completed using two 5-minute videos of interactions.
- Repetitive Behavior Scale-Revised (RBS-R) [ Time Frame: Baseline, Week 6 ]The RBS-R consists of six subscales covering a range of RRB subtypes including: Stereotyped Behavior, Self-injurious Behavior, Compulsive Behavior, Routine Behavior, Sameness Behavior, and Restricted Behavior. The presence and frequency of behaviors are rated on a 4-point scale (ranging from 0=behavior does not occur to 3=behavior occurs and is a severe problem).
- Social Responsiveness Scale, 2nd Edition (SRS-2), School-Age Form [ Time Frame: Baseline, Week 6 ]Five domains are assessed including: Social Awareness, Social Cognition, Social Communication, Social Motivation, and Restricted Interests and Repetitive Behavior. Items are scored on a 4-point scale (ranging from 1=not true to 4=almost always true).
- Aberrant Behavior Checklist (ABC) - Irritability and Social Withdrawal Subscales [ Time Frame: Baseline, Week 6 ]The subscales of the ABC include: Irritability, Social Withdrawal, Stereotypic Behavior, Hyperactivity/Noncompliance, and Inappropriate Speech. Items are rated on a 4-point scale (ranging from 0=no problem at all to 3 = problem is severe in degree).
- Anxiety, Depression and Mood Scale (ADAMS) [ Time Frame: Baseline, Week 6 ]28 symptom items that resolve into five subscales labeled: Manic/Hyperactive Behavior, Depressed Mood, Social Avoidance, General Anxiety, and Compulsive Behavior. Items are rated on 4-point scale ranging from 0=not a problem to 3=severe problem.
- Children's Communication Checklist-2 (CCC-2) [ Time Frame: Baseline, Week 6 ]A caregiver-report measure of language designed for use with children ages 4-16 years old who speak in sentences. The measures consists of 70 items making up 10 domains: Speech, Syntax, Semantics, Coherence, Inappropriate Initiation, Scripted Stereotyped Language, Use of Context, Nonverbal Communication, Social Relations, and Interests.
- Screen for Child Anxiety Related Disorders (SCARED), Parent Version [ Time Frame: Baseline, Week 6 ]The SCARED, Parent Version is a parent report measure developed to measure child anxiety symptoms. Subscales include Somatic Symptoms/Panic Disorder, Generalized Anxiety Disorder, Separation Anxiety, Social Phobia, and School Phobia. Items are rated on a 3-point scale ranging from 0=not true or hardly ever true to 2=very true or often true.
- Sleep Disturbance Scale for Children (SDSC) [ Time Frame: Baseline, Week 6 ]Six subscales including Disorders of Initiating and Maintaining Sleep, Sleep Breathing Disorders, Disorders of Arousal, Sleep Wake Transition Disorders, Disorders of Excessive Somnolence, and Sleep Hyperhydrosis. Items are rated on 5-point scale where 1=never and 5=always (daily). Subscale scores sum to equal a total score
- Vineland Adaptive Behavior Scales, Third Edition (Vineland-3) Parent/Caregiver Form [ Time Frame: Baseline, Week 6 ]Used to measure adaptive functioning across three core domains (Communication, Daily Living Skills, and Socialization), and two optional domains (Motor Skills and Maladaptive Behavior); items are rated on a 3-point scale (0=never; 1=sometimes; 2=usually or often). The core domains sum to a total Adaptive Behavior Composite.
- Clinical Global Impression-Severity (CGI-S): [ Time Frame: Screening, Baseline, Week 6 ]Reflects clinicians impression of severity of illness on a 7-point scale ranging from 1=not at all to 7=among the most extremely ill.
- Autism Family Experience Questionnaire (AFEQ) [ Time Frame: Baseline, Week 6 ]Parent/Caregiver form used to measure impact of autism interventions on family experience and quality of life. Items are rated on a 5-point scale where 1=always and 5=never.
- Anxiety Scale for Children - Autism Spectrum Disorder - Parent Versions (ASC-ASD-P) [ Time Frame: Baseline, Week 6 ]Parent/Caregiver form developed to detect symptoms of anxiety in youth with ASD. Composed of four subscales (Performance Anxiety, Uncertainty, Anxious Arousal, and Separation Anxiety), items are rated on a 4-point scale (0=never and 3=always). Subscales sum to equal a total score.
- Anxiety Scale for Children - Autism Spectrum Disorder (ASC-ASD-C) - Child Versions [ Time Frame: Baseline, Week 6 ]Child form developed to detect symptoms of anxiety in youth with ASD. Composed of four subscales (Performance Anxiety, Uncertainty, Anxious Arousal, and Separation Anxiety), items are rated on a 4-point scale (0=never and 3=always). Subscales sum to equal a total score.
- OSU Autism Clinical Global Impressions: Severity [ Time Frame: Screening, Baseline, Week 6 ]Reflects clinicians impression of severity of illness on a 7-point scale ranging from 1=not present to 7="classic" autism.
- OSU Autism Clinical Global Impressions: Improvement [ Time Frame: Week 6 ]Reflects clinicians impression of improvement on a 7-point scale ranging from 1=very much improved to 7=very much worse.
- Behavioral Inflexibility Scale (BIS) [ Time Frame: Baseline, Week 6 ]Parent/Caregiver measure designed to assess rigid patterns of behavior commonly associated with ASD. The measure is composed of 38 items rated on a 6-point Likert scale where 0=Not at all a problem and 5=Very severe or extreme problem. Items sum to a total score.
