This study is looking at the safety and efficacy of low field magnetic stimulation (LFMS) for treating patients with treatment resistant depression who are taking an antidepressant that is not working for them.
Full Title of Study: “Double-Blind, Proof-of-Concept (POC) Trial of Low Field Magnetic Stimulation (LFMS) Augmentation of Antidepressant Therapy in Treatment-Resistant Depression”
- Study Type: Interventional
- Study Design
- Allocation: Randomized
- Intervention Model: Parallel Assignment
- Primary Purpose: Treatment
- Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
- Study Primary Completion Date: May 2016
- Device: Low Field Magnetic Stimulation (LFMS)
- The LFMS devices produces a unique magnetic field that may help alleviate symptoms of depression.
- Device: Sham LFMS
- Sham LFMS looks and sounds like the active treatment but does not produce any magnetic stimulation.
Arms, Groups and Cohorts
- Active Comparator: Low Field Magnetic Stimulation
- Patients in this arm will receive 2 days of active low field magnetic stimulation (LFMS) in phase 1, followed by 2 days of active low field magnetic stimulation (LFMS) in phase 2. LFMS is a novel, non-contact neuromodulation technique. LFMS is administered through a device while the patient lies on his/her back for 20 minutes.
- Placebo Comparator: Sham (LFMS)
- Patients in this arm will receive 2 days of sham (not active) low field magnetic stimulation (LFMS) in phase 1, followed by 2 days of sham (not active) low field magnetic stimulation (LFMS) in phase 2.
- Other: Crossover Arm
- Patients in this group will receive two days of sham (not active) low field magnetic stimulation (LFMS) in phase 1, followed by two days of active low field magnetic stimulation (LFMS) in phase 2.
Clinical Trial Outcome Measures
- Hamilton Rating Scale for Depression – 6 Items
- Time Frame: Baseline and 48 hours after initiating treatment
- The total HAM-D-6 score is reported. The range of possible scores on the HAM-D-6 is from 0 to 22. Higher values indicate increased depression severity, and worse outcomes. This instrument is completed with a structured interview guide by the clinician based on his/her assessment of the patient’s symptoms. This structured interview has been validated for use with time frames shorter than one week.The time frame for this scale is the past 24 hours.
