Summary

To demonstrate that the RNS System is safe and effective as an adjunctive therapy in individuals age 12 through 17 years with medically refractory partial onset epilepsy.

Description

NeuroPace is sponsoring the RESPONSE Study with the RNS System in individuals age 12 through 17 with partial (focal) onset seizures who have undergone diagnostic testing that localized no more than 2 epileptogenic foci, are refractory to two or more antiepileptic medications, and currently have frequent and disabling seizures. For the purposes of this study, disabling seizures are defined as motor partial seizures, complex partial seizures, and/or secondarily generalized seizures. The RNS System is currently approved by the FDA for use in patients 18 years and older with hard-to-treat partial-onset seizures. The same device will be used in the RESPONSE Study.

The study is a prospective open label single arm pivotal study and participants will be followed for 2 years after placement of the RNS System. The study will enroll a maximum of 200 subjects within the United States to ensure that at least 150 subjects are implanted with the RNS System.

The study design includes one interim analysis which will occur after the 75th implanted patient reaches 12 months post-implant. If the study achieves its primary safety and effectiveness endpoint goals at the interim analysis, the study will be considered successful and enrollment will be stopped.

If the interim analysis does not achieve the primary safety and effectiveness endpoint goals, the study will continue enrolling up to the maximum of 200 patients. A final analysis will be conducted after the 150th implanted patient reaches 12 months post-implant.

Eligibility

Yes No Not Sure

Inclusion Criteria

Subject has disabling motor simple partial seizures, complex partial seizures, and/or secondarily generalized seizures. Disabling refers to seizures that are severe enough to cause injuries, or significantly impair functional ability in domains including employment, psychosocial education and mobility
Subject has seizures that are distinct, stereotypical events that can be reliably counted, in the opinion of the investigator, by the subject or parent/caregiver
Subject had an average of three or more disabling motor simple partial seizures, complex partial seizures and/or secondarily generalized seizures over the two most recent consecutive 30-day periods, with no 30-day period with less than two seizures per subject and/or parent/caregiver report
Subject failed treatment with a minimum of two anti-seizure medications (used in appropriate doses) with adequate monitoring of compliance and the effects of treatment, as determined by the investigator
Subject has undergone diagnostic testing as part of his/her standard care that has identified no more than two epileptogenic regions
Subject is male or a female of childbearing potential using a reliable method of contraception (hormonal, barrier method, surgical or abstention)
Subject is age 12 or older but will be less than age 18 (has not reached 18th birthday) at the time of implantation with the RNS System
Subject is able to maintain an electronic diary alone or with the assistance of a competent individual
Subject is able to attend clinic appointments in accordance with the study schedule
Subject and/or parent/guardian must be willing and able to provide informed consent and assent when appropriate
Subject is not currently implanted with an RNS Neurostimulator or NeuroPace Leads
In the investigator's opinion, subject is able to tolerate a neurosurgical procedure

Exclusion Criteria

Subject has been diagnosed with primarily generalized seizures
Subject requires procedures that are contraindicated based on current RNS System labeling
In the opinion of the investigator, the subject has a clinically significant or unstable medical condition (including alcohol and/or drug abuse) or a progressive central nervous system disease
Subject has been diagnosed with active psychosis, major depression or suicidal ideation in the preceding year. Subjects with post-ictal psychiatric symptoms need not be excluded
Subject is pregnant
Subject is participating in a therapeutic investigational drug or other device study
Subject is implanted with an electronic medical device that delivers electrical energy to the brain
Subject has been diagnosed with psychogenic or non-epileptic seizures
Subject has experienced unprovoked status epilepticus in the preceding year
Subject is taking chronic anticoagulants
Note: For contraindications, refer to current physician labeling (manuals) for the RNS
