This study will evaluate the safety and efficacy of deep brain stimulation in treating people with several and otherwise treatment-resistant depression.

Condition Intervention Phase
Device: Deep Brain Stimulation System
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Electrical Stimulation of the Internal Capsule for Intractable Depression

Further study details as provided by Butler Hospital:

Primary Outcome Measures:
  • Hamilton Depression Rating Scale (HDRS) [ Time Frame: Administered at base line, every 1 to 5 days during the acute phase (2 months), monthly during the chronic phase, then every three months during the open continuation phase ]

Secondary Outcome Measures:
  • Inventory for Depressive Symptoms, Self Report (IDS-SR) [ Time Frame: Administered at base line, every 1 to 5 days during the acute phase (2 months), monthly during the chronic phase, then every three months during the open continuation phase ]

Enrollment: 5
Study Start Date: December 2002
Primary Completion Date: May 2004 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Active DBS
Participants will receive deep brain stimulation.
Device: Deep Brain Stimulation System
In DBS, thin wires are used to carry electric current to the parts of the brain involved in depression symptoms. These wires are implanted surgically and are attached to battery operated stimulators usually implanted in the chest. The study doctor will adjust the settings of the electrical stimulation to optimize treatment for each participant.
Other Names:
  • Deep Brain Stimulation System from Medtronic, Inc.
  • Implantable Neurostimulator (INS)

  • Failure to respond to respond to:

    1. Adequate trials (greater than or equal to 6 weeks at the maximum recommended or tolerated dose) of primary antidepressants from at least 3 different classes and;
    2. Adequate trials (greater than or equal to 4 weeks at the usually recommended or maximum tolerated dose of augmentation/combination of a primary antidepressant using at least 2 different augmenting/combination agents (lithium, T3, stimulants, neuroleptics, anticonvulsants, buspirone, or a second primary antidepressant) and;
    3. An adequate trial of individual psychotherapy (greater than or equal to 20 sessions with an experienced psychotherapist)
