Brief Summary:
The primary objective of this trial is to assess device function and safety, with secondary objectives including the feasibility.

Condition or disease Intervention/treatment Phase
Loss of Control Eating Obesity, Morbid Device: responsive neurostimulation Not Applicable

Detailed Description:
This is a single site, early feasibility study to support development of a novel therapeutic approach for utilizing the NeuroPace RNS® System for nucleus accumbens responsive neurostimulation (NAc- RNS) to ameliorate loss of control over (LOC) eating in persons with treatment-refractory obesity, specifically those who have failed gastric bypass surgery. The primary objectives are to assess the safety & feasibility & potential efficacy of the medical device named the NeuroPace RNS® System

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 6 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Device Feasibility
Official Title: Responsive Neurostimulation For Loss Of Control Eating
Estimated Study Start Date : February 27, 2019
Estimated Primary Completion Date : January 1, 2025
Estimated Study Completion Date : January 1, 2025

Arm Intervention/treatment
Experimental: Responsive Neurostimulation
Surgical arm. Patients expected to receive treatment.
Device: responsive neurostimulation
The RNS® System is a novel, implantable therapeutic device that delivers responsive neurostimulation, an advanced technology designed to continuously monitor brain electrical activity, detect abnormal electrical activity and respond by delivering imperceptible levels of electrical stimulation to normalize that activity before an individual experiences seizures. This is an Early Feasibility Study determining the safety and efficacy of NAc-RNS in the treatment of LOC eating in treatment-refractory obesity.




Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Related Adverse Events [Safety and Tolerability] [ Time Frame: 5 years ]

    Safety of the RNS System and NAc stimulation through evaluation of AE's graded as "related" (vs. not related) to the intervention that will be graded based on severity.

    Grade 1 Mild AE Grade 2 Moderate AE Grade 3 Severe AE Grade 4 Life-threatening or disabling AE Grade 5 Death related to AE


  2. Count of Participants Exhibiting Overall Decrease in Loss of Control Episodes Per Week [ Time Frame: 5 years ]
    This endpoint will be met if at least 50% of subjects exhibiting a decrease in the number of Loss of Control (LOC) episodes per week. LOC episodes will be assessed by the currently available standard, ecological momentary assessment (EMA) diary entries.
