The Safety and Efficacy of Terpene-enriched Cannabidiol (CBD) Oil in ADHD

Recruiting now · Phase 2 · Has a placebo group

Conditions studied: Attention Deficit Hyperactivity Disorder (ADHD)

In brief

ADHD is the most frequent neurodevelopmental disorder in childhood. Symptoms often appear in preschool years, and most children (65-80%) continue to experience some ADHD-associated symptoms into adolescence and adulthood. The disorder is marked by age-inappropriate inattention, hyperactivity, and impulsivity. Drug treatments for ADHD include stimulants containing methylphenidate (like Ritalin and Concerta) or amphetamines (like Vyvanse). However, 30-35% of the patients do not respond well to these treatments, and stimulants may result with various side effects. The use of medical cannabis increases; applied for expending medical conditions, with growing evidence for its beneficial effects. A study on ADHD adults treated by cannabinoids demonstrated improvements in hyperactivity and impulsivity. The current study is aimed to examine the safety and efficacy of treating children diagnosed with ADHD with a CBD oil (devoid of THC), enriched with terpenes. Participants will be randomly assigned to receive either the enriched CBD oil or a placebo, for 5 weeks (Treatment, Stage I). At the end of the treatment stage (I), an open-label stage will follow (II), wherein, all participants will receive the investigational product for an additional 5 weeks. The investigators hypothesize that children treated with the enriched CBD oil (Treatment, Stage I) will show significantly higher improvement in hyperactivity and inattention scores, as compared with the placebo group.
