Clinical Trial: CBD Gel Is Safe and Effective in Fragile X Syndrome Patients

Chicago, IL: The administration of a proprietary transdermal CBD gel (aka ZYN002) is safe and effective in patients with Fragile X syndrome (FXS), according to phase 3 clinical trial data published in the Journal of Neurodevelopmental Disorders. FXS is a genetic disorder resulting in developmental delays, learning disabilities, and behavioral problems, such as aggression and attention deficits.

Over 200 pediatric patients (mean age 9.7 years) participated in the 12-week trial. Subjects received either CBD or placebo in addition to their prescribed medications. The study is the largest double-blind, randomized, placebo-controlled clinical trial ever conducted involving FXS patients. 

Consistent with prior studies, investigators reported that CBD treatment was effective, safe, and well-tolerated. No serious adverse events were reported. 

“In this trial, ZYN002 was well tolerated in patients with FXS and demonstrated evidence of efficacy with a favorable benefit risk relationship,” they concluded. “A confirmatory phase 3, randomized, controlled trial is being conducted in children and adolescent patients with FXS.”
