About this study

The purpose of this study is to determine the tolerability and optimal dose of cannabidiol (CBD) as an simultaneous treatment in children and young adults with Sturge-Weber syndrome (SWS) and drug resistant epilepsy.

Read the detailed description

We hope to gain an understanding of the utility of pure CBD used for the treatment of medically refractory epilepsy in SWS in this open-label, safety dose-finding, study. Recent evidence suggests that CBD has multiple, beneficial, effects in patients (such as those with SWS that undergo neurological deterioration) suffering from medically refractory seizures. We hypothesize that CBD will reduce seizure frequency in children and young adults with SWS and will therefore help stabilize and improve their neurologic status.This trial is part of an expanded access program, available through a partnership with GW Pharmaceutical, which has been sanctioned by the FDA to study the safety and efficacy of Epidiolex (cannabidiol/CBD) in participants with SWS and medically refractory seizures.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • CannabidiolDrug

    Also called Epidiolex, CBD

    Initiation of treatment will begin with 2mg/kg/day. The dose will be increased by 3 mg/kg/day after seven days and then by 5 mg/kg/day every seven days up to a maximum dose of 25 mg/kg/day given.

    The dose of concomitant antiepileptic drugs will remain unchanged during the first 12 weeks of CBD treatment (or until 8 weeks after steady state at final dose), unless symptoms of toxicity and/or significant changes in blood levels are observed.

Study groups in NCT02332655
Study groupRoleWhat they receive
CannabidiolExperimentalAll subjects will receive the experimental Epidiolex (cannabidiol) oral solution to be taken at home twice a day, and will be treated on an outpatient basis. The drug will be taken for 48 weeks unless the subject chooses to participate in the extension phase of the study, in which case the subject will continue to receive the drug for one additional year or until the drug is approved for clinical use for the treatment of epilepsy in patients with Sturge-Weber syndrome.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Seizures Per Month

    A baseline seizure frequency was recorded for each subject in a diary for eight weeks prior to investigational drug initiation and parents/caregivers documented seizures on a daily basis throughout the trial using a seizure log. For assessing the efficacy of CBD, the investigator counted the change in frequency of seizures per month. The number of seizures within 56 days of the baseline and the number of seizures within 56 days of week 14 were calculated. Higher seizure frequency indicates worse outcome. This outcome is measured as the change in number of seizures per month between the baseline and week 14 time points.

    Measured: Measured within 56 days before baseline and 56 days before week 14

Secondary outcomes (1)
  1. Percentage Change in Seizure Frequency at Most Recent Visit on CBD Compared With Baseline

    The percentage change, between the seizure frequency per month reported at baseline compared to seizure frequency per month at the subject's most recent visit, on CBD was calculated. Higher positive percentage change in seizure frequency per month would indicate better outcome. Positive values indicate a decrease in seizure frequency.

    Measured: Measured at Baseline and most recent visit within 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cannabidiol in people with Sturge-Weber Syndrome, run by Anne Comi, MD 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 0 inclusion and 13 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: finished, as of the sponsor's last update on 2 Mar 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 2 Mar 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?

Number of Seizures Per Month (time frame: Measured within 56 days before baseline and 56 days before week 14). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Mar 2022.
