This feasibility study investigates effects of EEG-based low frequency, low emission magnetic cortical stimulation in comparison to a sham treatment in subjects with moderate to severe depressive disorder.

Condition Intervention Phase
Major Depressive Disorder (MDD) Device: NeoSync EEG Synchronization Therapy Device: Sham NeoSync EEG Synchronization Therapy Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment

Further study details as provided by NeoSync, Inc.:

Primary Outcome Measures:
  • Percent Change in Hamilton Depression Rating Scale (HAMD-17) at Baseline and the End of Week 4 of Treatment. [ Time Frame: Assessed at baseline and the end of Week 4 of treatment. ]

    Outcome measured using the Hamilton Depression Rating Scale (HAMD-17) and calculated as percent change in severity score from baseline until the end of the 4th week of treatment.

    The HAMD-17 scale ranges between 0-54, with higher numbers indicating more severe symptoms. 0-7 is generally accepted to be within the normal range (or in clinical remission), while a score of 20 or higher indicates moderate to severe depression.

Secondary Outcome Measures:
  • Safety Profile of the Treatment [ Time Frame: Outcome assessed at the end of the 4th week of treatment. ]
    Describe the safety profile of the administration of low-emission sinusoidal magnetic fields above the subject's scalp. Safety criteria include adverse events, serious adverse events, and vital signs.

Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Active Fixed Alpha Frequency Magnetic Stimulation
Sinusoidal magnetic field set to the subject's intrinsic alpha frequency (IAF).
Device: NeoSync EEG Synchronization Therapy
Generate low-energy sinusoidal magnetic field above the scalp with frequency equal to the subject's intrinsic alpha frequency (IAF). Treatment is 30 minutes, administered 5 days per week for 4 weeks.
Active Comparator: Active Random Frequency Magnetic Stimulation
Magnetic field hops to random frequencies in the alpha band (8-13Hz), once per second.
Device: NeoSync EEG Synchronization Therapy
Generate low-energy sinusoidal magnetic field above the scalp with frequency equal to the subject's intrinsic alpha frequency (IAF). Treatment is 30 minutes, administered 5 days per week for 4 weeks.
Sham Comparator: Inactive Sham Treatment
Generate sound similar to active treatment, except that no magnetic field is generated.
Device: Sham NeoSync EEG Synchronization Therapy
A device that looks and sounds similar to the active treatment, but no magnetic field is generated.

Detailed Description:
Major Depressive Disorder (MDD) is associated with functional impairment and disability, and results in a significant burden on the affected individual, his or her family, and society in general. Psychopharmacological therapy has been shown to be effective, but may be accompanied by significant side effects. The investigators propose an alternative model, based on the relationship between symptoms, brain metabolism, and neural activity as recorded with electroencephalography (EEG). Subjects with MDD often have decreased brain metabolism, accompanied by increased EEG activity in the alpha band. The investigators hypothesis is that a gentle, non-significant risk, sinusoidal magnetic field above the subject's scalp, which oscillates at precisely his or her Intrinsic Alpha Frequency (IAF) can take advantage of this relationship to reduce symptoms without the significant side effects associated with pharmaceuticals. The investigators propose a 4-week, sham controlled, randomized, double-blind multi-center feasibility study to determine the efficacy of synchronized low energy magnetic fields delivered at the subject's IAF to treat MDD. Treatment will be given concomitant to the subject's existing medication, and will occur 5 days per week at the clinical site. Target enrollment is 45 adult subjects diagnosed with MDD.
