SANTE - Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy

Status Completed

Clinical Trial Summary

The purpose of this research is to study the safety and effectiveness of bilateral stimulation of the anterior nucleus of the thalamus as adjunctive therapy for reducing the frequency of seizures in adults diagnosed with epilepsy characterized by partial-onset seizures, with or without secondary generalization, that are refractory to antiepileptic medications.

Clinical Trial Description

Medtronic, Inc. is sponsoring an investigational study of the Medtronic DBS Therapy for epilepsy, the company's deep brain stimulation (DBS) therapy for patients with refractory epilepsy. Epilepsy is a condition that affects 2.3 million Americans, and about one-third of these patients are refractory, or continue to experience seizures despite a wide range of treatment options.

The prospective, randomized, double-blind trial uses existing technology to test whether bilateral stimulation of the anterior nucleus of the thalamus can safely and effectively reduce seizure frequency in patients with epilepsy. It includes enrollment of 157 patients at 17 sites in the U.S. 110 patients were implanted and monitored for 13 months following implant, with long-term follow-up until the device is approved or the study is stopped. 109 of the 110 implanted subjects were randomized to Active stimulation or Control.

Patients in the active group, who received neurostimulation, were monitored for a reduction in seizure rates compared to the control group, who did not receive neurostimulation during the three-month double-blind phase. After the double-blind phase, all patients received neurostimulation.

Candidates for the trial were adults with partial-onset epilepsy for whom at least three antiepileptic drugs have proven ineffective. They were to have had an average of six or more seizures per month. Candidates continued to receive their epilepsy medications while participating in the trial.

Deep brain stimulation therapy has already received approval in the United States, Europe, Canada, and Australia for the treatment of Essential Tremor and Parkinson's disease. Deep brain stimulation is not approved in the United States for the treatment of epilepsy. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
