Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Rhythm (SANTE RR)

January 27, 2012 updated by: MedtronicNeuro

Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Rhythm (SANTE RR)

The primary objective is to demonstrate that a higher proportion of responders to deep brain stimulation (DBS) in the anterior nucleus (AN) of the thalamus in refractory epilepsy patients in the SANTE study exhibit a recruitment rhythm relative to non-responders.

Study Population

The study will enroll the number of patients necessary to achieve the required sample size of 18 responders and 18 non-responders at a minimum of six (6) centers participating in the U.S. SANTE study.

Description

Inclusion Criteria:

  • Enrolled in the SANTÉ study, have been implanted with a complete DBS system, and is currently receiving stimulation in the long-term follow-up phase (post Month 13) of the study
  • Patient or legal representative is able to understand and provide signed consent for participating in the study
  • Willing and available to attend the visit as scheduled and to comply with the study protocol

Exclusion Criteria:

  • Patients unable to tolerate stimulation turned OFF during the testing period
  • Are pregnant or suspected of being pregnant

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Responder
A subject having at least a 50% reduction in total seizure frequency compared to the SANTE study 3-month Baseline Phase
There was no intervention. This study was designed as an in-clinic testing protocol to identify recruitment rhythms.
Non-responder
A subject with a less than 50% reduction in total seizure frequency compared to the SANTE study 3-month Baseline Phase.
There was no intervention. This study was designed as an in-clinic testing protocol to identify recruitment rhythms.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
To demonstrate that a higher proportion of DBS responders exhibit a RR relative to non-responders, using maximum tolerated voltage settings, at activated electrode contacts used for DBS stimulation in the SANTE study.
Time Frame: Study testing to occur during the long-term follow-up phase of the SANTE trial.
Study testing to occur during the long-term follow-up phase of the SANTE trial.

Secondary Outcome Measures

Outcome Measure
Time Frame
For patients without a RR at their activated DBS electrode contacts used in the SANTE study, demonstrate that activating other electrode contacts generates a RR.
Time Frame: Study testing to occur during the long-term follow-up phase of the SANTE trial.
Study testing to occur during the long-term follow-up phase of the SANTE trial.
