Detailed Description
The primary objective of this study:
- To compare the relative efficacy, as measured by a change in the 6-item Hamilton Rating Scale for Depression (HAM-D6), of 20 and 60 minutes of LFMS compared to sham (placebo) in subjects with treatment resistant depression (TRD).
Secondary objectives:
- To determine if subjects with TRD may respond to 120 minutes of LFMS.
- To determine the persistence of response to LFMS therapy during the observation period.
- To evaluate the safety and tolerability of LFMS.

- Have been treated with adjunctive antipsychotic medication with an antidepressant for at least two weeks during the current depressive episode.
- Are deemed to be at significant risk for suicidal behavior
- Are unable to lie on their back for the duration of study treatment
Have a lifetime history of:
- Delirium, dementia, amnestic, or other cognitive disorder;
- Schizophrenia or any psychotic disorder, based on the Structured Clinical Interview for DSM-5 Axis I Disorders Patient Edition (SCID-I/P);

- An eating disorder active within the 12 months prior to the screening visit (Visit 1);
- Comorbid anxiety disorders that predominate over MDD, as assessed by the investigator;
- Alcohol or substance use disorder active within the 12 months prior to the screening visit (Visit 1);
- Clinically significant DSM-5 Axis II disorder.
- Have ever received electroconvulsive therapy, vagal nerve stimulation, deep brain stimulation or repetitive transcranial magnetic stimulation.

Measure Description |
Time Frame |
---|---|---|
Change From Baseline to ( Day 4) in the 6-item Hamilton Rating Scale for Depression (HAM-D6) Total Score.
Time Frame: Week 1 Day 4
|
Hamilton Rating Scales for Depression were designed to measure the severity of depressive symptoms in subjects with primary depressive illness. HAM-D6 is a subset of the HAM-D17 that assesses 6 items associated with major depression. The scale uses HAM-D17 items 1, 2, 7, 8, 10 and 13. Item 13 is scored 0 to 2 and all others are scored 0 to 4. Total score ranges from 0 to 22; higher score indicates more depression. Change from baseline: mean score at Week 1 Day 4 minus mean score at baseline". Week 1 Day 4 : Change from baseline to the end of the efficacy period ( Day 4) in the 6-item Hamilton Rating Scale for Depression (HAM-D6) total score .Responders at Day 4 will be defined as those subjects who achieve a decrease in HAM-D6 total score of 50% or more compared to baseline (Day 1, Week 1). All other subjects will be deemed to be non-responders at Day 4. Each patient's total score is his/her own reference for determining a decrease of 50% or more. |

Change From Day 4 in HAM-D6 Total Score at Day 11 for Week 1 Non-responders: Response to 120 Minutes LFMS
Time Frame: Day 11 (Week 2)

Hamilton Rating Scales for Depression were designed to measure the severity of depressive symptoms in subjects with primary depressive illness. HAM-D6 is a subset of the HAM-D17 that assesses 6 items associated with major depression. The scale uses HAM-D17 items 1, 2, 7, 8, 10 and 13. Item 13 is scored 0 to 2 and all others are scored 0 to 4. Total score ranges from 0 to 22; higher score indicates more depression. Change from Day 11: mean score at Week 2 Day 11 minus mean score at Day 4". To determine if subjects with TRD who are non-responders to 0, 20 or 60 minutes of LFMS on Day 4 may respond to 120 minutes of LFMS at the end of Day 11. Responders will be defined as those subjects who achieve a decrease in HAM-D6 total score of 50% or more compared to baseline (Day 1, Week 1). All other subjects will be deemed to be non-responders. Each patient's total score is his/her own reference for determining a decrease of 50% or more. |
Day 11 (Week 2)
|
Day 4 Responders: Persistence of Effect Based on Pre-specified HAM-D6 Total Score
Time Frame: Day 42
|
To determine the persistence of response to LFMS therapy during a four-week follow-up period in subjects who were responders at Day 4. Persistence of response was achieved if during Week 2 post baseline visits and follow-up visits subjects' 6-item Hamilton Rating Scale for Depression (HAM-D6) total scores were lower than or equal to 50% of the baseline ( Day1 Week1) scores.
Non-responder imputation method was used where missing post-baseline dichotomous ("yes or no") were imputed as non-responder.
Logistic regression model used to compare treatment groups for each visit, where the model considers the treatment, age and gender as covariates.
