A Phase 1 interventional study of Epidiolex 100 mg/mL Oral Solution and Placebo in Electrical Status Epilepticus of Slow-Wave Sleep, sponsored by Northwell Health. Completed at 1 site in United States. Open to participants aged 2 Years to 17 Years. Per ClinicalTrials.gov, last updated 2026-08-28.

This study aims to assess the efficacy of Epidiolex in patients with ESES. ESES is characterized by sleep potentiated spikes with a spike index greater than 85% (conventional definition) and 50% (new definition)1. Several drugs including: steroids, intravenous Gama globulin, Clobazam, other benzodiazepines, Valproic acid, and other anti-epileptic drugs have been tried with mixed benefits2,3. Cannabidiol (CBD) would provide a novel mechanism of action to assess for its efficacy in this population. This will be a double-blind placebo-controlled crossover clinical trial.
This study attempts to view the effect of Epidiolex on subjects with Electrical Status Epilepticus of Sleep (ESES). ESES can cause various types of seizures which can fluctuate during sleep. Similar studies have been conducted with Epidiolex with other seizure disorders such as Lennox-Gastaut syndrome (LGS) and Dravet Syndrome. Since there is no data available on the effect of Cannabidiol (CBD) on patients with ESES, this study hopes to fill that void. As such, patients that have been diagnosed with ESES will be eligible to participate in this study to ascertain whether or not Epidiolex can reduce the frequency or intensity of the seizures brought on by ESES during sleep.

Exclusion Criteria:An individual who meets any of the following criteria will be excluded from participation in this study:
Epidiolex (Cannabidiol) is a colorless to yellow solution in a 100mL vial that is to be administered with a 5mL syringe.The starting dosage is 2.5 mg/kg twice daily, or 5 mg/kg/day. After one week, the dosage can be increased to a maintenance dosage of 5mg/kg twice daily, or 10 mg/kg/day. Patients who are tolerating Epidiolex at 10mg/kg per day and require further reduction of seizures may benefit from a dosage increase up to a maximum recommended maintenance. Dosage of 10mg/kg twice daily (20mg/kg/day), in weekly increments of 2.5 mg/kg twice daily(5mg/kg/day), as tolerated. For patients in whom a more rapid titration from 10 mg/kg/day to 20 mg/kg/day is warranted, the dosage may be increased to no more frequently than every other day administration of the 20 mg/kg/day. Dosage resulted in somewhat greater reductions in seizure rates than the recommended maintenance dosage of 10 mg/kg/day, but with an increase in adverse reactions.
Drug: Epidiolex 100 mg/mL Oral Solution
Placebo is a colorless to yellow solution in a 100mL vial that is to be administered with a 5mL syringe. The starting dosage is 2.5 mg/kg twice daily, or 5 mg/kg/day. After one week, the dosage can be increased to a maintenance dosage of 5mg/kg twice daily, or 10 mg/kg/day. Patients who are tolerating Placebo at 10mg/kg per day and require further reduction of seizures may benefit from a dosage increase up to a maximum recommended maintenance. Dosage of 10mg/kg twice daily (20mg/kg/day), in weekly increments of 2.5 mg/kg twice daily(5mg/kg/day), as tolerated. For patients in whom a more rapid titration from 10 mg/kg/day to 20 mg/kg/day is warranted, the dosage may be increased to no more frequently than every other day administration of the 20 mg/kg/day. Dosage resulted in somewhat greater reductions in seizure rates than the recommended maintenance dosage of 10 mg/kg/day, but with an increase in adverse reactions.
Other: Placebo
Epidiolex is a schedule 5 controlled substance that is a colorless to yellow oral liquid solution that is prepackaged into 100mL vials with 5mL syringes for use. It is typically used for the treatment of seizures associated with Lennox-Gastaut syndrome (LGS) or Dravet Syndrome in patients 2 years of age and older.
Placebo is composed of dehydrated alcohol, sesame seed oil, strawberry flavor, and sucralose.
Frequency of Spike Wave Index
Assess the reduction in spike wave index by evaluating the differences in activity from the four 24-hour ambulatory EEGs each participant obtains while enrolled in this study
Time frame: Up to 20 weeks
Likert Scale Assessment
The secondary objective is to assess seizure counts and subjective behavior change on a 5 point Likert scale (1= no improvement, 2= some improvement, 3=moderate improvement, 4=significant improvement, 5=extreme improvement).
Time frame: Up to 20 weeks
