Read the detailed description
This is a multi-center, open label study to evaluate the long term safety of everolimus in patients with TSC and refractory seizures currently being treated in the Novartis-sponsored study EXIST-3 study and are judged by their parent study investigator as benefiting from the current study treatment. The study is expected to remain open for approximately 10 years (or until 31-Dec-2022 in the UK) from First Patient First Visit (FPFV).
Patients will continue to be treated in this study until they are no longer benefiting from their everolimus treatment as judged by the Investigator or until one of the protocol defined discontinuation criteria is met or everolimus becomes commercially available according to local regulations.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing everolimus in people with Tuberous Sclerosis Complex, run by Novartis Pharmaceuticals at 67 sites in 18 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 21 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 67 sites in United States, United Kingdom, Spain, France, Italy and 13 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Occurances of adverse events and serious adverse events (time frame: Day 1 up to approximately 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Aug 2026; AzTrials last refreshed its copy on 6 Nov 2026.
