简要总结
This trial consists of 2 parts: a double-blinded phase and an open-label extension phase. The open-label extension phase only will be described in this record. All participants will receive the same dose of GWP42003-P. However, investigators may subsequently decrease or increase the participant's dose until the optimal dose is found.

结局指标
主要结局
Number of Participants With Any Treatment-emergent Adverse Events, Discontinuations Due to AEs, Serious AEs, and Treatment-related AEs (TEAE)
时间窗: OLE Day 1 up to 4 years
An adverse event (AE) was defined as any new unfavorable/unintended signs/symptoms (including abnormal laboratory findings), or diagnosis or worsening of a pre-existing condition, which occurred following screening and at any point up to the post-treatment safety follow-up visit, which may or may not be related to the IMP. An AE that started, or worsened in severity or seriousness, following the first dose of IMP was considered a TEAE. A serious AE was defined as any AE that results in any of the following outcomes: death, life-threatening adverse experience, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or cancer, any other experience that suggests a significant hazard, contraindication, side effect or precaution that may require medical or surgical intervention to prevent one of the outcomes listed above, or an event that changes the risk/benefit ratio of the study.
Number of Participants With Any TEAE, by Severity
时间窗: OLE Day 1 up to 4 years
An adverse event (AE) was defined as any new unfavorable/unintended signs/symptoms (including abnormal laboratory findings), or diagnosis or worsening of a pre-existing condition, which occurred following screening and at any point up to the post-treatment safety follow-up visit, which may or may not be related to the IMP. An AE that started, or worsened in severity or seriousness, following the first dose of IMP was considered a TEAE. Grade 1 (Mild) is defined as asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated. Grade 2 (Moderate) is defined as minimal, local or noninvasive intervention indicated; limiting age appropriate instrumental activities of daily living (ADL). Grade 3 (Severe) is defined as medically significant but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; limiting self care ADL.

- Percent Change From Baseline in the Number of TSC-associated Seizures During the OLE Treatment Period(OLE Day 1 up to 4 years)
- Percent Change From Baseline in Total Seizure Frequency During the OLE Treatment Period(OLE Day 1 up to 4 years)
