Trial Outcomes & Findings for Long-Term Safety of Pharmaceutical Grade Synthetic Cannabidiol Oral Solution in Pediatric Participants With Treatment-Resistant Childhood Absence Seizures (NCT NCT03355300)

NCT ID: NCT03355300

Last Updated: 2023-06-18

Results Overview

An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product during the course of a clinical investigation. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product, whether or not thought to be related to the investigational product. An SAE is any untoward medical occurrence that results in death, is life-threatening, requires the participant be at a risk of death at the time of the event, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital abnormality/birth defect, or other serious event that requires medical or surgical intervention. A summary of SAEs and all other non-serious AEs, regardless of causality, is located in the Reported AEs module.
