Detailed Description
The population under study comprises a real-world patient population with difficult to treat depression: patients diagnosed with unipolar or bipolar disorder with chronic or recurrent depression who fail to achieve an adequate response to standard psychiatric management.
The diagnosis of depression and comorbid disorders will be determined based on the Mini International Neuropsychiatric Interview (MINI).
A minimum of five hundred (500) patients will be implanted with a VNS Therapy System and up to eighty (80) sites may participate in this study.
Enrollment will take 8 years, based on competitive enrollment. For each subject a baseline visit will occur between 1 and 6 weeks before implant.
Once implanted with the device, subjects will be followed-up for a minimum of 36 months and a maximum of 60 months. The study may stop when the last subject has reached the 36 months follow-up.

Sampling Method
Study Population
The population under study comprises a real-world patient population with difficult to treat depression: patients diagnosed with unipolar or bipolar disorder with chronic or recurrent depression who fail to achieve an adequate response to standard psychiatric management.
The diagnosis of depression and comorbid disorders will be determined based on the Mini International Neuropsychiatric Interview (MINI).
Description
Inclusion Criteria:
- Be at least 18 years of age.
- Have a documented primary diagnosis of chronic (>2 years) or recurrent (2 or more prior episodes) major depressive episode that has not adequately responded to an adequate number of antidepressant treatments, as per local medical standards. This diagnosis must be confirmed using the MINI.
- Provide written Ethics Committee (EC) or Institutional Review Board (IRB) approved informed consent and Health Insurance Portability and Accountability Act (HIPAA, US only) authorization (as applicable according to local requirements).
- Currently is receiving at least one antidepressant treatment (i.e., antidepressant drug, maintenance electroconvulsive therapy, or formal psychotherapy including supportive psychotherapy) or mood stabilizing treatment for bipolar patients (such as lithium, anticonvulsants, or atypical antipsychotics).
- Able and willing to comply with the frequency of (outpatient) clinic visits and to reliably complete all the evaluations as specified in the study protocol.Hence based on the nature of their disease, the following patients should not be included: patients with mental retardation, current severe or significant substance/alcohol abuse, diagnosis of one or more schizophrenia-spectrum or other psychotic disorders, diagnosis of borderline or severe personality disorder as determined by clinical judgment which, in the investigator's opinion, would significantly interfere with subject's participation in the study)
Exclusion Criteria:
There are no exclusion criteria; the investigator should refer to the (local applicable) VNS Therapy Physician's Manual.

Vagal Nerve Simulation (VNS) Therapy
The aim of this study is to include patients with difficult to treat depression from a global "real world" (standard of care) population who are referred for treatment with VNS Therapy.
|
A VNS Therapy System used for vagus nerve stimulation and consisting of an implantable VNS Therapy generator, lead, and external programming system.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The primary endpoint of this study is response defined as reduction in Montgomery Åsberg Depression Rating Scale (MADRS) total score of at least 50% from baseline to 12 months post implant.
Time Frame: 12 months
|
MADRS is a 10-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Each item yields a score of 0 to 6. The overall score ranges from 0 to 60. Higher MADRS score indicates more severe depression. A 'Responder' is a subject that achieved ≥ 50% reduction from baseline in MADRS total score at the M12 assessment. A 'Non-Responder' is any patient who did not achieve ≥ 50% reduction from baseline in MADRS score at the M12 assessment. No formal hypothesis testing is presented; all the proposed statistical tests are descriptive in nature. The Primary endpoint analysis as defined above will be done only on patients that are enrolled while in a major depressive episode (MDE); the cut off point for current MDE at time of implant will be a MADRS score of 20. For the patients with a MADRS score below 20 at time of enrollment, only the continuous change in MADRS can be described (as the MADRS can only worsen or stay the same). |

Changes in depression score As measured by the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR).
Time Frame: through study completion, an average of 4 years
|
The Quick Inventory of Depressive Symptomatology (QIDS-SR) is a 16-item, subject-completed questionnaire of the symptoms of mood and depression.
The total score ranges from 0 to 27.
A higher QIDS-SR score indicates a more severe depression.

Time Frame: through study completion, an average of 4 years
|
*Optional assessments: to be done at selected sites only and based on investigator's clinical judgment to decide which subjects complete them. The Altman Self-rating Mania Scale (ASRM) is a 5-item self-reported diagnostic scale which can be used to assess the presence and severity manic and hypomanic symptoms, most commonly in patients diagnosed with bipolar disorder. The total score ranges from 0 to 20. A score of 6 or higher indicates a high probability of a manic or hypomanic condition. |
