Study design is a Phase IIb prospective multi-center, randomized, placebo-controlled, double-blind clinical trial. The goal will be to enroll 80 infants with Tuberous Sclerosis Complex who are less than 6 months of age prior to the onset of their first seizure
The investigators are running an intervention study for young children with Tuberous Sclerosis Complex (TSC). The study will include free play-based behavioral intervention that may improve social and communication skills in children with TSC. Eligible families will have a child in the age range of 12-36 months, with a diagnosis of TSC. A parent must also be available to attend the weekly intervention sessions at UCLA. The intervention will focus on teaching caregivers skills to improve the social and communication outcomes of their children. The content of the intervention will be individually tailored to the child's developmental level. The intervention involves pre-assessments, an intervention period of daily 60 minute sessions for 10 days, followed by weekly 60 minute sessions for 10 weeks, and post-assessments. The classroom can have up to 3 parent-child dyad and the curriculum focuses on improving social-communication and play skills.
This trial consists of 2 parts: a double-blinded phase and an open-label extension phase. The blinded phase only will be described in this record. Participants will receive 1 of 2 doses of GWP42003-P or matching placebo. The primary clinical hypothesis is that there will be a difference between GWP42003-P and placebo in their effect on seizure frequency.
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.
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.
Both Neurofibromatosis type 1 (NF1) and Tuberous Sclerosis Complex (TSC) are highly heterogeneous diseases. Cognitive features seem to vary widely even between family members carrying the same mutation. This phenotypic variability is not well understood, but is generally assumed to be caused by modifier genes which regulate the affected pathways. However, recent studies brought forward an alternative explanation for the phenotypic variability. Post-mortem studies showed that second hit mutations causing loss of the second ('healthy') allele are more widespread than previously believed. These loss of heterozygosity (LOH) mutations cause bi-allelic loss of the disease-linked gene and are known to cause the gross of somatic features in both diseases (like neurofibromas and hamartomas). Hence, it could be the stochastic occurrence of second-hit mutations in the brain are the cause of the variable cognitive phenotypes. To investigate to what extent these LOH mutations in the brain contribute to the phenotype and to what extent this variation is due to genetic modifiers factors is unknown. The investigators therefore propose to elucidate this variability by comparing the correlation of cognitive features of monozygotic twins with NF1 or TSC to healthy twins in the population. If modifier genes are the cause of the variability of cognitive features in NF1 and TSC the investigators expect that the variability in cognitive tests in monozygotic twins is the same as monozygotic twins in the healthy population. However, if the variability is caused by the occurrence of LOH mutations, the investigators expect to have a lower correlation in our monozygotic patients compared to the healthy twins.
In this research study, the investigators are evaluating the clinical benefit of everolimus in cancer patients with inactivating TSC1 or TSC2 mutations or activating MTOR mutations. This research study is a Phase II clinical trial, which tests the safety and effectiveness of an investigational drug called everolimus to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is being studied. It also means that the FDA (the U.S. Food and Drug Administration) has not yet approved everolimus for your type of cancer. Everolimus is a drug that may stop cancer cells from growing by blocking an important factor (mTOR) involved in the growth of cells. This drug has been used in treatment for other cancers and is approved by the Food and Drug Administration for treatment of several types of cancer, including renal cell carcinoma. Treatment with this drug has been associated with responses in some patients whose cancers had mutations in TSC1 or TSC2. The investigators think that patients whose tumors have mutations in TSC1 or TSC2 may have a good chance of responding to treatment with drugs like everolimus.
The primary objective of clinical part of EPISTOP project is to identify the clinical and molecular biomarkers of epileptogenesis in a prospective clinical study of patients with TSC. Secondary objective of the clinical part of EPISTOP is to compare the effects of standard antiepileptic treatment in patients diagnosed as having epilepsy after clinical seizures vs after electroencephalographic epileptiform discharges, in a randomized trial in TSC patients.
The purpose of this research study is to see if simvastatin can be taken safely in patients with either LAM or TSC, who are already being treated with everolimus or sirolimus. This is the first step in looking at simvastatin as a drug that may help patients, by impacting the growth and survival of cells that make up the lung lesions that cause problems in LAM and TSC patients. The study also seeks to learn more about how simvastatin works, when given to patients being treated with everolimus or sirolimus, and to evaluate the safety and any potential benefit to patients taking this 2-drug combination. The primary objective of this study is to determine the safety of simvastatin in the treatment of LAM-S or LAM-TS in patients on a stable (for at least 3 months) dose of sirolimus or everolimus. Secondary objectives include: - To assess the effect of simvastatin on forced expiratory volume in 1 second (FEV1). - To assess the effect of simvastatin on forced vital capacity (FVC). - To assess the effect of simvastatin on diffusing lung capacity (DLCO). - To assess the effect of simvastatin on vascular endothelial growth factor -D (VEGF-D) serum levels. - To assess the effect of simvastatin with questionnaire- based assessments of dyspnea, fatigue, and quality of life (QOL). - Assess signs of clinical benefit.
