About
Objectives of this study are to determine whether active VNS Therapy treatment is superior to a no stimulation control in producing a reduction in baseline depressive symptom severity, based on multiple depression scale assessment tools at 12 months from randomization.
Full description
A prospective, multi-center, randomized, controlled, blinded trial of subjects implanted with VNS Therapy. Active treatment and no stimulation control are randomized, at least two weeks after implantation and observed for 12-months.
After completing the 12 month endpoint in the RCT portion of the study, all RECOVER subjects will transition into the prospective, open-label, longitudinal portion of the study. Subjects in the control arm of RECOVER will be activated after completing the 12 month endpoint.
After completion of enrollment in the RCT portion or meeting of interim success criterion (whichever comes first), up to 5,800 new subjects may enroll directly into the open-label,prospective, longitudinal study. These subjects will participate in the study for approximately 5 years.
The study has been designed in accordance with The Centers for Medicare and Medicaid Services coverage with evidence development (CED) decision entitled "Decision Memo for Vagus Nerve Stimulation (VNS) for Treatment Resistant Depression (TRD) (CAG-00313R2).
