Neuronetics, Inc. has announced results from a new, dual-arm randomized pilot study that showed a trend toward symptomatic improvements with once-monthly TMS maintenance therapy in medication-free patients treated with NeuroStar TMS Therapy® for Major Depressive Disorder (MDD). Six weeks of acute NeuroStar TMS Therapy induced remission in 61.2 percent of all enrolled patients. At three months, 62.5 percent of medication-free patients randomized to once-monthly treatment with NeuroStar TMS Therapy maintained response as compared to 43.8 percent of patients who did not receive maintenance treatment. The complete findings were presented at the 167th American Psychiatric Association Annual Meeting in New York City.
