A Randomized, Double-Blind, Placebo-Controlled Multiple-Center, Efficacy and Safety Study of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Fragile X Syndrome - RECONNECT


The purpose of this study is to investigate how effective and safe ZYN002, a transdermal gel, is in participants with FXS. The drug product ZYN002 is a pharmaceutically manufactured CBD. It is being developed as a clear gel that can be applied to the skin (called transdermal delivery), to provide consistent, controlled levels of CBD in the blood when it is given twice a day. Participants will be assigned by chance to get one of the following study treatments: Active study drug – ZYN002 or placebo. Assigning study drug by chance is called “randomization,” and it is an important part of testing an experimental study drug. Participants will be randomly assigned to study treatment according to a computer program and will have 1 in 2 chance of receiving the active study drug.
