A Pilot Study To Evaluate The Effects of Everolimus on Brain mTOR Activity and Cortical Hyperexcitability in TSC and FCD

Completed · Phase 2

Conditions studied: Epilepsy, Tuberous Sclerosis Complex, Focal Cortical Dysplasia

In brief

The purpose of this study is to measure if the drug called Everolimus effects mTOR signaling (an electrical activity signal in the brain) in patients with Tuberous Sclerosis Complex (TSC) and Focal Cortical Dysplasia (FCD) with treatment resistant epilepsy (TRE) who will be undergoing brain surgery. One group of patients will be treated with Everolimus, and another will not. Researchers will determine if there is a difference in mTOR signaling between the patients who were treated with Everolimus and those who were not. Previous studies have suggested that Everolimus may reduce seizure activity in TSC patients by decreasing mTOR signaling. Since patients with FCD may also have excess mTOR signaling brain activity, Everolimus may also reduce seizure activity in these patients. The drug Everolimus is approved by the Food and Drug Administration to treat specific types of breast, pancreatic, and kidney cancer, a kidney tumor called an angiomyolipoma (common in patients with TSC), and TSC patients who have a brain tumor called a subependymal giant cell astrocytoma (SEGA). However, in this research it is considered to be an investigational since it is not approved for reduction in mTOR signaling and a decrease in seizure frequency. Researchers believe that Everolimus may be useful in reducing something called cortical hyperexcitability, which is the excess brain activity that can contribute to seizures.
