Official Title

Double-Blind, Proof-of-Concept (POC) Trial of Low Field Magnetic Stimulation (LFMS) Augmentation of Antidepressant Therapy in Treatment-Resistant Depression

Brief Overview


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.

to screening

- Subject has had electroconvulsive therapy in the current episode of depression

- Subject has had Transcranial Magnetic Stimulation or has received treatment with
other experimental devices for the treatment of the current episode of depression

- Subject has received Vagus Nerve Stimulation at any time

- Dementia, delirium, amnestic, or other cognitive disorders

- There is a clinically significant abnormality on the screening physical examination

- Participation in any clinical trial with an investigational drug or device within the
past month or concurrent to study participation
