Detailed Description
This is an open-label, single-center study recruiting approximately 15 male or female pediatric (ages 2-15, inclusive) patients with, intractable epilepsy, on stable doses of antiepileptic drugs (AEDs). The study comprised of the following period: 4 weeks observation period, followed by a 2-week dose titration period, 10-week maintenance treatment period, and a 2-week follow-up of which 1 week is a tapering-off period. Seizures will be recorded by the legal guardian/caregiver in seizure diaries throughout the first 16 weeks of the study.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: PLT101 PTL101 capsules (50 or 100 mg CBD per capsule) up to 25 mg/kg/day or up to 450 mg/day, the lower of the two. Twice daily (morning and evening). |

Outcome Measures
Primary Outcome Measures
- Incidence of study treatment related adverse events (AEs) [12 weeks of treatment + 2 weeks follow up]
- Percent change in mean countable monthly seizure frequency [12 week treatment period]
Secondary Outcome Measures
- Incidence of all adverse events (AEs) [12 weeks of treatment + 2 weeks follow up]
- assessment of Caregiver Global Impression of Improvement using a 5-point rating scale [after 5 weeks of maintenance dose and at end of treatment]
- assessment of Caregiver Global Impression of Seizure Severity using a 5-point rating scale [after 5 weeks of maintenance dose and at end of treatment]
