Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Treatment Resistant Depression Device: Vagal Nerve Stimulation (VNS) Not Applicable

Detailed 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), new subjects may enroll directly into the open-label,prospective, longitudinal study. These subjects will participate in the study for approximately 5 years.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 1000 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: 1:1 randomization of active stimulation vs. no stimulation for 12 months post randomization.
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description: Central Rater and sponsor are blinded in the RCT phase. Sites will need to have an unblinded programmer who is only programming the device and not collecting outcomes data.

Arm Intervention/treatment
Active Comparator: Active
Group will have VNS activated 2 weeks post implant.
Device: Vagal Nerve Stimulation (VNS)
VNS is an implantable device that delivers stimulation to the vagal nerve.
Other Name: VNS

Sham Comparator: Control
Group will be implanted with VNS but device is not activated for the first 12 months. After 12 months, this group can receive stimulation.
Device: Vagal Nerve Stimulation (VNS)
VNS is an implantable device that delivers stimulation to the vagal nerve.
Other Name: VNS




Primary Outcome Measures :
  1. Montgomery Åsberg Depression Rating Scale (MADRS) Rate of Response [ Time Frame: 12 months post randomization ]
    Percentage of subjects with at least a 50% reduction from baseline in MADRS total score at 12 months from randomization

  2. Montgomery Åsberg Depression Rating Scale (MADRS) Time to First response [ Time Frame: Baseline up to 12 Months ]
    Time from randomization to the first observed MADRS response.

  3. Montgomery Åsberg Depression Rating Scale (MADRS) Time to First Remission [ Time Frame: Baseline up to 12 Months ]
    Time from randomization to the first observed MADRS remission.

  4. Montgomery Åsberg Depression Rating Scale (MADRS) Duration of Response [ Time Frame: Baseline up to 12 Months ]
    Duration of MADRS response, defined as the number of consecutive months from first observed MADRS response to the first assessment of MADRS response relapse (defined by reduction from baseline is < 40%).

  5. Montgomery Åsberg Depression Rating Scale (MADRS) Rate of Remission [ Time Frame: Baseline up to 12 Months ]
    Total amount of time (months) of subject in remission divided by the total months of study participation up to 12 months from randomization. Subjects discontinuing the study before the 12 months assessment will be considered as not in remission for each successive month after discontinuance.

  6. Montgomery Åsberg Depression Rating Scale (MADRS) Maximum duration of Response [ Time Frame: Baseline up to 12 Months ]
    Maximum duration of MADRS response, defined as the maximum number of consecutive months in response (only for subjects experiencing MADRS response).

  7. Montgomery Åsberg Depression Rating Scale (MADRS) Duration of Remission [ Time Frame: Baseline up to 12 Months ]
    Duration of MADRS remission, defined as the number of consecutive months from first observed MADRS remission to the first assessment of MADRS remission relapse (defined score > 20).

  8. Montgomery Åsberg Depression Rating Scale (MADRS) Maximum duration of Remission [ Time Frame: Baseline up to 12 Months ]
    Maximum duration of MADRS remission, defined as the maximum number of consecutive months in remission (only for subjects experiencing MADRS remission).

  9. Assess all Adverse Events [ Time Frame: Implant to 12 Months ]
    All adverse events, with a focus on device or procedure-related serious adverse events.

  10. WHO Disability Assessment Schedule (WHODAS) Changes in scores over [ Time Frame: Baseline to 12 Months ]
  11. Health Outcome Scale (EQ-5D-L) Changes in scores over time [ Time Frame: Baseline to 12 Months ]
  12. Clinical Global Impressions Scale - Improvement (CGI-I) Response [ Time Frame: 12 months post randomization ]
    A CGI-I score ≤ 2 at 12 months from randomization. Subjects discontinuing the study before the 12 months assessment will be considered as not in response for each successive month after discontinuance.

  13. Sheehan Suicidality Tracking Scale (S-STS) Changes in Suicidality [ Time Frame: Implant to 12 Months ]
    Suicide attempts as measured by items #10 & #12 in S-STS scale

Criteria

Inclusion Criteria:

The patient must be in a major depressive disorder (MDD) episode for ≥ two years or have had at least four episodes of MDD, including the current episode.

The patient's depressive illness meets a minimum criterion of four prior failed treatments of adequate dose and duration as measured by a tool designed for this purpose.

The patient is experiencing a major depressive episode (MDE) as measured by a guideline recommended depression scale assessment tool on two visits, within a 45-day span prior to implantation of the VNS device.

Patients must maintain a stable medication regimen for at least four weeks before device implantation.

Exclusion Criteria:

Current or lifetime history of psychotic features in any MDE;

Current or lifetime history of schizophrenia or schizoaffective disorder;

Current or lifetime history of any other psychotic disorder;
