About this study
Official title: The Effects of Cannabidiol (CBD) on Electrical and Autonomic Cardiac Function in Children
The investigators propose to study the effects of cannabidiol (CBD) on cardiac electrical function and the autonomic nervous system in children with Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS), when the CBD is administered as an artisanal oil obtained through state dispensaries or other sources. The intent is to begin to assess potential risks and benefits of this therapy in a vulnerable patient population by characterizing the effects of CBD on EKG findings, heart rate variability and the occurrence of seizures.

Specific Aims/Study Objectives
This is a pilot study to explore the effects of cannabidiol (CBD) on autonomic cardiac function in children with Dravet syndrome (DS) or Lennox-Gastaut syndrome (LGS) when the CBD is administered as an artisanal oil. This will be achieved by addressing the following specific aims.
Aim #1: To determine the effects of CBD on cardiac function in 30 children with DS and LGS. This is the primary aim of the study: The effects of CBD on the cardiac function of 30 children with DS or LGS will be assessed using a 15-lead electrocardiogram (EKG) and a 24-hour Holter monitor. Investigators hypothesize that there will be no alterations in ventricular repolarization and heart rate variability on the EKG and Holter monitoring, respectively, after taking CBD for 4-8 weeks, compared to when participants were not taking CBD.
Note: The following aims are secondary to the primary outcome and goal of assessing the effects of CBD on cardiac function.
Aim #2: To assess signs and symptoms of dysautonomia in the presence and absence of CBD. Signs and symptoms of dysautonomia include parental perception of body temperature, skin color in hands and feet, sweating, pupil size, flushing, feeding issues, heart rate, strong emotions, constipation, urination or bowel movement issues, and irritability. These signs and symptoms will be collected using a previously-established dysautonomia survey. Investigators hypothesize there will be no change in qualitative assessments of signs and symptoms of dysautonomia after taking CBD for 4-8 weeks, compared to when participants were not taking CBD.
Aim #3: To determine the effects of CBD on the occurrence of seizures. The number of seizures in children who obtain CBD will be assessed using a 7-day seizure diary (Seizure tracker). Caregivers will record the number of seizures for a 7-day period prior to CBD administration, and repeat the seizure tracking after having received CBD for 4-8 weeks. Change in seizure numbers will be compared pre- and post-CBD administration. Investigators hypothesize that study participants will have lower seizure counts after being on CBD compared to when weren't taking CBD.
Study Design and Methodology
Study Design: Thirty patients with DS or LGS who are going to register to take medical cannabis (cannabidiol, or CBD) in the state of Minnesota will be offered the opportunity to participate in this study. If consent is obtained, the patient or guardian will be asked to complete a questionnaire developed for this study that documents observable signs and symptoms of dysautonomia, and to complete a seizure diary for 7 days prior to initially receiving the CBD. Each participant will also have a 15-lead electrocardiogram (EKG) and wear a 24-hour Holter monitor, both non-invasive measures of cardiac function, prior to being administered the CBD. The EKG and 24-hour Holter monitor will be interpreted by a cardiac electrophysiologist and will be reviewed for heart rate variability parameters. The dysautonomia questionnaire, seizure diary and cardiac measurements will be repeated 4-8 weeks after the subject has been on a stable regimen of CBD. This time-frame is based on availability of subjects schedules and clinic visits, and it is also greater than 5 half-lives previously reported for CBD (apparent half-life, 21 hours, (15)). Steady-state levels are achieved after 5 half-lives of drug dosing, thus we expect to be at steady-state concentrations.
Subjects who are already on a stable regimen of CBD, yet plan to stop taking CBD at some point for some reason, are also eligible to participate. The parent or guardian will complete the dysautonomia questionnaire and seizure diary (and research staff will be available to help with questions), and the patient will have the 15-lead EKG and 24-hour Holter monitor while still on the CBD. The subjects will then come back 4-8 weeks after their last dose of CBD to have these assessments repeated while off of the CBD. This time frame is based on availability of subjects schedules and clinic visits as well as being substantially greater than 5 half-lives of CBD, the standard wash-out period for pharmacological studies.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing 12-Lead ECG and Cannabidiol in people with Lennox-Gastaut Syndrome and Dravet Syndrome, run by Gillette Children's Specialty Healthcare at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 30 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Jan 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Holter SDNN Parameter Change (time frame: Baseline to 4 to 8 week follow up visit). It is what the study was designed to measure, not a finding.
