Synchronized Transcranial Magnetic Stimulation (sTMS) in Major Depressive Disorder

This study is designed to evaluate the safety and efficacy of synchronized transcranial magnetic stimulation (sTMS) using the NeoSync EEG Synchronized TMS device (NEST) in subjects with Major Depressive Disorder. This is a multicenter study in which subjects will be randomized to receive treatment 5 days per week for 6 weeks. Subjects who complete 6 weeks of double-blind treatment may be eligible to receive up to four weeks of open label sTMS therapy or antidepressant medications during the follow-up phase of the study. Follow-up evaluation visits will be conducted during those four weeks, with the frequency of the visits determined by the treatment choice during that timeframe.
