Clinical Trial Summary

This study is designed as a prospective, multi-centered, double-blind, randomized, controlled 12-month pivotal study to evaluate the safety and efficacy of the ANS Libra® Deep Brain Stimulation System for patients with major depressive disorder who have failed at least 4 treatments in the current episode. The primary outcome assessment will occur at 6 months: however, all patients will be followed for 1 year. A total of 201 patients will be randomized from up to 20 sites.

Each potential patient will be pre-screened according to the inclusion/exclusion criteria. A narrative of what study participation entails, will be used to educate potential participants on study requirements. Prior to on-site baseline evaluations, the patient will sign the informed consent. Patients will then undergo 3 baseline evaluations, with each of these evaluations to occur no less than 2 weeks apart from each other. The first 2 baseline visit evaluations will be performed by separate psychiatrists in order to confirm the patient's diagnosis. All patients will be scheduled for surgery, to occur no less than two weeks and no more than 1 month after final baseline evaluation, to implant the ANS Libra® Deep Brain Stimulation system. After device implantation, patients will be randomly assigned to 1 of 2 groups in a 2:1 ratio (Active Treatment Group & Control Group).

After system implant (Week 0), the patient will return to clinic approximately 2 weeks after surgery for evaluation and treatment randomization into either Group 1 or Group 2 (Group 1 = Active Treatment Group; Group 2 = Control Group). Patient will then return to clinic for subsequent evaluations at 2 weeks, 4 weeks, 6 weeks, 8 weeks, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, and 1 year post system implantation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Montgomery and Asberg Depression Rating Scale (MADRS) Score at Baseline and the Average of Months 4, 5, and 6	The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. The lower a score the less symptom severity is seen.	Baseline to 6 months
Secondary	Baseline MADRS to MADRS at 1 Year	The MADRS is a ten-item diagnostic questionnaire used to measure the severity of depressive episodes in patients with mood disorders. Higher MADRS score indicates more severe depression, and each item yields a score of 0 to 6. The overall score ranges from 0 to 60. The lower a score the less symptom severity is seen.	Baseline to 1 year
Secondary	Number of Participants With Adverse Events (i.e., Hospitalization Due to Worsening Depression, Suicidal Ideation or Behavior, Medical Treatment, and Device Related Events) That Occur Over Study Duration		6 months-1 year
Secondary	Global Assessment Scale (GAF) Score at Baseline and 1 Year	The Global Assessment Scale (GAF) is a hypothetical continuum of mental health illness that looks at psychological, social, and occupational functioning. It measures how much a person's symptoms affect their day to-day life on a scale of 0 to 100. A score of 100-91 indicates no symptoms, 90-81 indicates absent minimal symptoms, 80-71 indicates symptoms that are transient and reactions expectable to psychosocial stressors, 70-61 indicates mild symptoms, 60-51 indicates moderate symptoms, 50-41 indicates serious symptoms, 40-31 indicates some impairment in reality testing or communication OR major impairment in several areas, 30-21 indicates delusions or hallucinations, 20-11 indicates danger of hurting self or others OR occasionally fails to maintain personal hygiene, 10-1 indicates persistent danger of severely hurting self or others OR persistent inability to maintain minimal personal hygiene OR serious suicidal act with clear expectation of death and 0 indicates inadequate data.	1 year
Secondary	Hamilton Rating Scale for Depression - 17 Item (HRSD-17) Score at Baseline and 6 Months	The Hamilton Rating Scale for Depression - 17 item (HDRS-17) ranging from 0-52 used to assess potential changes in the severity of depressive symptoms (Hamilton 1960; Hamilton 1967). It is used to evaluate depressed mood, vegetative and cognitive symptoms of depression, and co-morbid anxiety symptoms. Scoring is based on the 17-itemscale and scores of 0-7 are considered as being normal, 8-16 suggest mild depression, 17-23 moderate depression and scores over 24 are indicative of severe depression; the maximum score being 52 on the17-point scale.	6 months
Secondary	Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) Score From Baseline to 1 Year	The Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q) is a self-report instrument designed to measure the degree of enjoyment and satisfaction experienced by subjects in various areas of daily functioning. There are 16 areas of functioning, each scored from 1 (very poor) to 5 (very good). The range of scores is 16-80, with lower scores representing lower functioning and satisfaction.	1 year
Secondary	Inventory of Depressive Symptomology (IDS-C30) Score From Baseline to 1 Year	The construction of the Inventory of Depressive Symptomology (IDS-C30) was intended to remedy deficits in the Hamilton Scale for Depression (HRSD-17) and Montgomery and Asberg (MADRS) depression rating scales by, among others, including all nine symptom domains needed to diagnose a DSM-IV major depressive episode in order to assess symptom remission, improve ability to detect milder levels of symptoms than the HRSD-17, and provide unconfined and more equivalent weighting among items. There are two versions of the IDS with identical items: a clinician rating (IDS-C30) and a self-report (IDS-SR30). Each of the 30 items is rated from 0 to 3, with increasing severity represented by a higher rating. (Rush et al. 1996). When complete, the IDS-C30 and IDS-SR30 are scored by summing responses to 28 of the 30 items to obtain a total score ranging from 0 to 84. Either appetite increase or decrease, but not both, are used to calculate the total score.	1 year
Secondary	Quick Inventory of Depressive Symptomatology (QIDS-SR) Scores From Baseline to 1 Year	The Quick Inventory of Depressive Symptomatology Self Report (QIDS- SR) is a 16-question shortened self-test, derived from the 30-item IDS. Questions in the QIDS - SR-116 correlate with the nine DSM-IV symptom criterion domains, including: Sleep disturbance (initial, middle, and late insomnia or hypersomnia) (Q 1 - 4), Sad mood (Q 5), Decrease/increase in appetite/weight (Q 6 - 9), Concentration (Q 10), Self-criticism (Q 11), Suicidal ideation (Q 12), Interest (Q 13), Energy/fatigue (Q 14), Psychomotor agitation/retardation (Q 15 - 16). The severity of depression can be judged based on the total score ranging from 1-27. A score of 1-5 indicates No depression, 6-10 indicates Mild depression,11-15 indicates Moderate depression, 16-20 indicates Severe depression and 21-27 indicates Very severe depression.	1 year
Secondary	Work and Social Adjustment Scale (WSAS) Score From Baseline to 1 Year	The WSAS is a modification of a scale introduced by Hafner and Marks (1976), consisting of 0-8 point ratings of the extent to which symptoms interfere with five areas of daily functioning: work, home management, private leisure, social leisure, and family relationships. It is a well-validated, widely used self-report measure. Additional time points include weeks 4, 8, 12, 16, and 40. A total score calculated as a sum of all items (possible range 0-40) was used in the analyses with higher scores indicating more impairment.	1 year
