Roll-over Study to Collect and Assess Long-term Safety of Everolimus in Patients With TSC and Refractory Seizures Who Have Completed the EXIST-3 Study [CRAD001M2304] and Who Are Benefitting From Continued Treatment

The purpose of this study is to evaluate the long-term safety in patients with TSC and refractory seizures who are currently receiving everolimus treatment in the Novartis-sponsored EXIST-3 study and who are determined to be benefiting from continued treatment as judged by the investigator at the completion of EXIST-3

Phase 3 trials are pivotal studies with large patient populations (hundreds to thousands) designed to prove efficacy and safety for FDA submission. A successful Phase 3 readout is typically the last major hurdle before a New Drug Application (NDA) or BLA filing.

Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.

Novartis AG (NVS) is the sponsoring company for this trial. BiotechSign currently grades this company D (36/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
