- Patients must have a diagnosis of FXS through molecular documentation of full mutation of the FMR1 gene documented through genetic testing at Screening.
- Patients with a history of seizure disorders must currently be receiving treatment with a stable regimen of no more than two AEDs for the four weeks preceding study Screening; or must be seizure-free for one year if not currently receiving AEDs.
- Patients who are taking psychotropic medication(s) should be on a stable regimen of no more than three such medications for at least four weeks preceding study Screening and must maintain that regimen throughout the study.

- History of significant allergic condition, significant drug-related hypersensitivity, or allergic reaction to any compound or chemical class related to ZYN002 or its excipients.
- Exposure to any investigational drug or device ≤30 days prior to Screening or at any time during the study.
- Patient has alanine aminotransferase (ALT), aspartate aminotransferase (AST), or total bilirubin levels ≥2 times the upper limit of normal (ULN) or has alkaline phosphatase levels ≥3 times the ULN as determined from Screening safety laboratories.
- Use of cannabis or any THC or CBD-containing product within 3 months of Screening Visit or during the study (aside from ZYN002).
