简要总结
Sturge Weber Syndrome (SWS) is a rare disease that affects the patient's brain and causes benign (non-cancerous) tumors to grow in the brain. One of the symptoms of SWS is epilepsy. People with epilepsy have seizures. Some patients may also have eye problems and a red mark on their facial skin.
This study is being done to find out if the study drug, everolimus, is safe and has helpful effects in patients with SWS who have seizures and are not responding to their current anti-epileptic medication.
The study drug, everolimus (Afinitor®), is supplied by Novartis Pharmaceuticals Corporation.
详细描述
The main study part has 3 phases. The first phase is called the baseline phase and consists of 1-2 study site visit(s). During this phase, the investigators will gather information about the subject, his/her medical history, and current health.
During the second phase of the study, the subject will start taking the study drug. It will take approximately 4 weeks to find out the right amount of study drug the subject should be taking. This process is called the titration phase. There will be 2 visits during the titration phase.
Once the subject are on the right amount of study drug, he/she will take that dose for about 12 weeks. This phase is called the maintenance phase and consists of 3 study site visits.
At the end of the maintenance phase, if the study doctor determines that taking everolimus has helped to reduce the number of seizures the subject has, he/she will have the choice to continue taking the study drug for an extended time. There will be 4 total study site visits during the extension phase.

研究组 & 干预措施
Everolimus
Afinitor tablets will be administered at a starting dosage of 5 mg/ m2/ day, dosed once per day in the morning. To achieve appropriate doses for all subjects 2mg, 3mg, 5mg of everolimus Disperz tablets will be used. Subjects will take one or more of these tablets in combination to achieve the required dose. Dosages will be rounded to the nearest 2 mg when calculating doses for individual subjects.
干预措施: Everolimus (Drug)
结局指标
主要结局
Evaluate the clinical effectiveness of Everolimus as an adjunct treatment to reduce the seizure activity
时间窗: 2 years
The primary efficacy parameter will be the percentage of subjects classified as responders (greater than 50% reduction in seizure frequency during the maintenance phase as compared to the baseline phase) or near-responders (25-50% reduction in seizure frequency during the maintenance phase as compared to the baseline phase), as reported by caregivers via seizure diaries.
次要结局
- Clinical progression of glaucoma(2 years)
- Clinical progression of facial and/or body port-wine hemangioma(2 years)
