PuLsE 2-Observational Long-Term Effectiveness Follow-Up Study of PuLsE 1 (PuLsE 2)
A Post-Market, Open Observational Long-term Effectiveness Follow-up Study of Participants With Drug-resistant Epilepsy With Partial-onset Seizures Previously Enrolled in a Randomized Controlled Trial (E-100: PuLsE) Comparing Best Medical Practice With or w/o Adjunctive Vagus Nerve Stimulation Therapy

Description détaillée
In 2005 Cyberonics, Inc. initiated PuLsE: an open, prospective, randomized, parallel group study directly comparing Best Medical Practice with and without adjunctive VNS Therapy.
In July 2008, the decision was made to discontinue this study due to lower than expected enrolment, impairing the possibility to meet the primary objective with appropriate statistical power. However, the relatively large number of participants (n=121) randomized in the original PuLsE study offers the possibility to generate scientifically valuable and original findings if additional follow-up data can be gathered. After consultation with the PuLsE Investigators, Cyberonics decided to implement an observational long-term follow-up of the participants enrolled in the original PuLsE study.

Exploratory evaluations
Délai: 5 years
|
The objective of this post-market study is to perform exploratory evaluations to identify clinically and statistically significant predictors of response at all follow-up visits in participants with drug-resistant epilepsy with partial-onset seizures treated with Best Medical Practice with or without adjunctive VNS Therapy.
This will be accomplished through regression modeling of the response variates (including change in baseline quality of life score and percent reduction in seizure frequency).
