Objective: To analyze the cumulative efficacy and safety of everolimus in treating subependymal giant cell astrocytomas (SEGA) associated with tuberous sclerosis complex (TSC) from an open-label phase II study (NCT00411619). Updated data became available from the conclusion of the extension phase and are presented in this ≥5-year analysis.
Methods: Patients aged ≥ 3 years with a definite diagnosis of TSC and increasing SEGA lesion size (≥2 magnetic resonance imaging scans) received everolimus starting at 3mg/m(2) /day (titrated to target blood trough levels of 5-15ng/ml).
Tuberous sclerosis complex (TSC) is a genetic disorder that can affect multiple organ systems, including the brain, heart, skin, kidney, and lung, by formation of benign hamartomas. It can be associated with autism, epilepsy, and other neurocognitive and behavioral disabilities. The incidence of TSC is approximately 1 in 6,000 live births, but it may be underdiagnosed.

Everolimus is an mammalian target of rapamycin complex 1 inhibitor with demonstrated benefit in several aspects of TSC. We report the first prospective human clinical trial to directly assess whether everolimus will also benefit epilepsy in TSC patients.

Methods: This was an open-label extension phase of a prospective, phase 1-2 trial (NCT00411619) in patients ≥3 years of age with SEGA associated with TSC. Patients received oral everolimus starting at 3 mg/m2 per day and subsequently titrated, subject to tolerability, to attain whole blood trough concentrations of 5-15 ng/mL.
