Everolimus for treatment-refractory seizures in TSC: Extension of a randomized controlled trial.

ABSTRACT:

Background

EXamining everolimus In a Study of Tuberous sclerosis 3 (EXIST-3) demonstrated significantly reduced seizure frequency (SF) with everolimus vs placebo. In this study, we evaluate the long-term efficacy and safety of everolimus for tuberous sclerosis complex (TSC)-associated treatment-refractory seizures.

Methods

After completion of the core phase, patients could enter an open-label extension phase and receive everolimus (target exposure, 3-15 ng/mL) for ≥48 weeks. Efficacy end points included change from baseline in average weekly SF expressed as response rate (RR, ≥50% reduction) and median percentage reduction (PR).

Results

Of 366 patients, 361 received everolimus in core/extension phases. The RR was 31% (95% CI, 26.2-36.1; N = 352) at week 18, 46.6% (95%
