On May 31, 2019 the FDA held a public hearing about cannabidiol (CBD) products. The day-long hearing saw comments and presentations from stakeholders ranging from nonprofit organizations like ASTM International to the Grocery Manufacturers Association, a food, beverage and consumer product trade association. Corporate entities in the cannabis industry also provided testimony, such as ingredient manufacturer Mile High Labs, which supplies products like CBD isolate and concentrate, and Socati, which provides high-CBD genetic varieties and extraction processes. Pharmaceutical companies like Zynerba Pharmaceuticals Inc., which produces the drug Connect-FX, were also present. Connect-FX is a CBD transdermal gel for treating Fragile X syndrome (Martin-Bell syndrome), a rare genetic disorder that causes developmental problems like intellectual disabilities. It is currently being evaluated as an experimental treatment for use in child patients in clinical trials.
