NAUTILUS Trial Summary

This trial shows that the RNS System for thalamic stimulation is safe and effective for reducing primary generalized seizures in individuals 12 years of age or older with drug-resistant idiopathic generalized epilepsy.

Who is the study for?
This trial is for individuals aged 12 or older with drug-resistant idiopathic generalized epilepsy who haven't had a neurostimulator implanted. They must have experienced at least two tonic-clonic seizures recently, be on stable seizure medication, and able to attend clinic visits. Women of childbearing age should use reliable contraception.Check my eligibility
What is being tested?
The RNS System NAUTILUS Study tests the safety and effectiveness of responsive thalamic stimulation as an additional treatment for reducing primary generalized seizures compared to sham (fake) stimulation in participants with drug-resistant epilepsy.See study design
What are the potential side effects?
While not specified here, side effects may include discomfort or complications from the implant surgery, possible infection risk, device-related issues like malfunction or migration, and potential neurological effects such as changes in mood or memory.
