NQ TMS for MDD Therapy Using 1 Day x 3 Sessions Protocol for Adult Patient

Transcranial Magnetic Stimulation (TMS) Therapy is a non-invasive procedure that uses magnetic pulses to stimulate the cortex (brain) to treat Major Depressive Disorder (MDD). Currently established therapy uses one 19-minute treatment session per day for 5 days per week for 6 weeks, for a total of 30 treatment sessions. The goal of this clinical trial is to evaluate the safety and effectiveness of an accelerated but shortened TMS dosing regimen for adults with MDD aged 22-85. Participants in this study will be subjected to the same 19-minutes treatment session, but three times on the same day, and only for one day. This will greatly reduce the logistical burden of completing the therapy regime.

Study Description: This single center, open label study will evaluate the safety and efficacy of accelerating the delivery of the NeuroQore TMS system's rectangular waveform rTMS protocol for the treatment of adults with MDD aged 22-85. Currently cleared protocol with the FDA (the Standard of Care Protocol) is one 19-min treatment session a day for 5 days/week for 6 weeks. The accelerated protocol will involve the same 19-min treatment session offered three times in a single day, with no additional treatment sessions. Primary Objectives: 1. To assess the efficacy of the NeuroQore TMS system, with accelerated delivery in the treatment of adults with MDD, as measured by a change in MADRS score 24 hours and 7 days after the treatment end. 2. To compare the safety profile of the accelerated delivery protocol to the historical safety profile of the Standard of Care protocol. Endpoints: Primary * Change in MADRS score from baseline to 24 hours and 7 days post-treatment. * Number and type of adverse events. Secondary * Change in PHQ-9 score from baseline to 24 hours and 7 days post-treatment. Study Population: Men and women 22-85 with MDD that have failed one medication in the current episode. Study Intervention: NeuroQore TMS System includes (1) a pulse generator, (2) a magnetic coil, (3) a coil cooler, and (4) a chair with a headpiece. It has been cleared for clinical use (K232688) by the FDA for the treatment of MDD using a 19-min Standard of Care protocol. Treatment during this study will be administered according to this protocol and following the instructions in the device user manual. Personalized stimulation targets will be produced from participants' structural MRI via the proprietary targeting generation component of the NeuroQore TMS system. Only personnel trained and certified by NeuroQore will be permitted to administer treatment. All session and device information will be captured on appropriate data collection forms. Study Duration: The study is anticipated to last up to 6 months including enrollment and follow-up. Individual participant duration in the study will be 1 day of treatment, 24-hour and 7-day follow-up.
