Details and patient eligibility


This is a prospective open label study assessing the efficacy and tolerability of pharmaceutical grade cannabidiol--Epidiolex (R), for the treatment of anxiety in pediatric patients with pediatric epilepsy that has been difficult to treat and requires ongoing use of anticonvulsant medication.

Full description

This study is an open label, adjunctive, proof of concept clinical trial. Prospective participants will be considered for the study if neurologic status suggests the need for continued treatment, and behavioral characteristics are clinically significant. All participants will receive active treatment, involving flexible dose titration of Epidiolex® and will be monitored for a period of four months. The study will be monitored and overseen by the Johns Hopkins Hospital Institutional Review Board.


20 estimated patients
