• Patient must have at least 4 clinically countable seizures per month. They must also have prior concomitant video-EEG with evidence documenting a diagnosis of epilepsy. Seizure history to include a documented history of generalized seizures (drop attacks, atonic, tonic-clonic and/or myoclonic), focal seizures without loss of consciousness with a motor component, focal seizures with loss of consciousness, or focal seizures with secondary generalization.
• Drug resistant epilepsy defined as a trial of at least four drugs, including one trial of a combination of two concomitant drugs, without successful seizure control. Vagal nerve stimulation, responsive neurostimulation, RNS, deep brain stimulation, or the ketogenic diet can be considered equivalent to a drug trial and documented evidence of drug and other therapeutic failures.
• Between 1-4 baseline anti-epileptic drugs at time of enrollment. Vagus nerve stimulator (VNS), ketogenic diet and modified Atkins diet do not count toward this limit and are not contraindicated for inclusion.
• Subject and family sign assent (if capable)/consent/research authorization and are able to meet the study expectations for appointments for the duration of the study
• VNS, if in use must be on stable settings for a minimum of 1 month.
• If on ketogenic diet, must be on stable ratio for a minimum of 3 months.
• Patients or their caregivers must be able to consistently maintain a seizure diary for at least 2 months prior to enrollment and during the course of the study period.
• Must be Nebraska state resident.

You may not qualify if…

• Renal, hepatic, pancreatic, or hematologic dysfunction as evidenced by: values above upper limits of normal for blood urea nitrogen (BUN)/creatinine, or values twice the upper limit of normal for serum transaminases [alanine transaminase (ALT), serum glutamic pyruvic transaminase (SGPT), aspartate transaminase (AST), serum glutamic-oxaloacetic transaminase (SGOT)], values twice the upper limit of normal for serum lipase and amylase, platelets <80,000 /miroliter (mcL), white blood cell count (WBC)<3.0 103 /mcL
• Less than 4 countable (non-countable seizures includes absence and myoclonic) seizures per month
• Use of cannabis-related product within last 30 days
• Active substance abuse/addiction.
• CBD is contraindicated in pregnancy and breastfeeding. Female subjects who are pregnant will be excluded from the study. If a female subject is able to become pregnant, she will be given a urine pregnancy test before entry into the study. Female subjects will be informed not to become pregnant while taking cannabidiol, and must agree to an acceptable method of barrier contraception use during the study which should include abstinence or a double barrier method for the duration of treatment.
• Female subjects must tell the investigator and consult an obstetrician or maternal-fetal specialist if they become pregnant during the study. If pregnancy occurs, CBD will be stopped in the most clinically appropriate manner.
