Intended Use

The NeuroStar TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

Device Story

NeuroStar TMS Therapy System is a computerized, electromechanical device delivering non-invasive, pulsed magnetic fields to induce electrical currents in the cerebral cortex. System components include a mobile console with a graphical user interface, a gantry-supported treatment coil, a laser-guided head support system, and SenStar Connect (a consumable for contact sensing and field monitoring). Operated by clinicians in hospitals, clinics, or physician offices, the system delivers TMS therapy to treat MDD. The device includes TMS TrakStar software for practice data management, patient record retrieval, and data communication across systems. The system is prescription-only. By stimulating cortical neurons, the device aims to provide therapeutic benefit to patients resistant to antidepressant medication. The current modification updates labeling to allow inter-train intervals of 11–26 seconds, reducing total treatment time from 37.5 to 18.8 minutes.

Clinical Evidence

Evidence based on a literature review of 79 human studies (3359 subjects, 2162 active TMS). Effectiveness analysis included 44 studies (50 active arms) and four meta-analyses. Safety analysis included 61 studies (67 active arms, 2836 subjects). Eleven studies (1069 subjects) specifically used the NeuroStar system or progenitor devices. Results indicate that varying inter-train intervals between 11 and 26 seconds does not impact TMS efficacy or the risk profile (including seizure incidence) compared to fixed intervals.

Technological Characteristics

Electromechanical system; ferromagnetic treatment coil; laser-guided positioning. Delivers pulsed magnetic fields (185 usec nominal pulse width). Connectivity via TMS TrakStar data management system. Software-controlled GUI. Non-sterile, multi-use SenStar Connect consumable for contact sensing and field cancellation. Operates within inter-train interval range of 10-60 seconds.

Indications for Use

Indicated for adult patients with Major Depressive Disorder (MDD) who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

#### Device Description:

The NeuroStar TMS Therapy System is a computerized, electromechanical medical device that produces and delivers non-invasive, magnetic stimulation using brief duration (185 usec nominal) rapidly alternating, or pulsed, magnetic fields to induce electrical currents directed at spatially discrete regions of the cerebral cortex. This method of cortical stimulation by application of brief magnetic pulses to the head is known as Transcranial Magnetic Stimulation or TMS. NeuroStar TMS Therapy is a non-invasive tool for the stimulation of cortical neurons for the treatment of adult patients with Major Depressive Disorder (MDD) who have failed to receive satisfactory improvement from prior antidepressant medication as described under Intended Use. The NeuroStar System is used for patient treatment by prescription only under the supervision of a licensed physician. It can be used in both inpatient and outpatient settings including physician's offices and clinics, and hospitals.

{4}------------------------------------------------

The NeuroStar TMS Therapy System is an integrated system consisting of a combination of hardware, software, accessories and consumable supplies. It includes a Mobile Console which houses the electronics, includes a software controlled graphical user interface, and gantry that supports the Treatment Coil. The ferromagnetic Treatment Coil delivers NeuroStar TMS Therapy®. The Head Support System provides accurate positioning of the Treatment Coil using a laser-guided alignment system. The SenStar® Connect is a non-sterile, multi-use consumable which is applied to the Treatment Coil, provides contact sensing to monitor contact of the treatment coil with the patient's head throughout a treatment session, quality control by monitoring the magnetic field level prior to patient treatment and provides surface field cancellation to reduce stimulation of the scalp. The TMS TrakStar™ practice data management system consists of a stand-alone computer and data management software that facilitates recording and retrieval of patient and treatment information and communication of data among multiple NeuroStar TMS Systems.

### Intended Use:

The NeuroStar TMS Therapy System is indicated for the treatment of Major Depressive Disorder in adult patients who have failed to receive satisfactory improvement from prior antidepressant medication in the current episode.

## Technological Characteristics and Substantial Equivalence:

The subject device, NeuroStar TMS System, has the following similarities to the predicate TMS device (NeuroStar TMS Therapy System, K133408):

- Principles of operation
- Design for delivery of Transcranial Magnetic Stimulation (TMS) ●
- O Output stimulation parameters (pulse width, frequency range, pulse interval range, etc.)
- . Materials

The change for the NeuroStar TMS Therapy System is a modification to the labeling of the device to allow a range of intervals from 11 to 26 seconds, rather than the fixed 26 second duration, which will allow a reduction in treatment time from 37.5 minutes to a minimum of 18.8 minutes. The change is intended to address physician and patient requests for a reduced treatment time due to issues of comfort and convenience to improve access. The proposed change is supported by information submitted in this premarket notification and with the following rationale:

- 1. Device is substantially equivalent to the FDA-cleared NeuroStar TMS Therapy System: The NeuroStar TMS Therapy System that is the subject of the premarket notification is the same device cleared by the FDA under DEN070003/K061053, K083538, K130233 and K133408. This change remains within the existing product specification for inter-train interval (range 10-60 seconds for > 1 pulse per second).
- 2. Device new clinical data supports the revised labeling: New clinical data obtained from a review of clinical trials conducted with the NeuroStar TMS Therapy System and reference

{5}------------------------------------------------

TMS devices demonstrate the use of inter-train intervals in the proposed range from 11 to 26 seconds does not impact the safety and efficacy of the NeuroStar TMS Therapy System for its Intended Use.

Changes to the device labeling include revised instructions for use to include a range of intertrain intervals from 11 to 26 seconds depending on physician and patient preference. No other changes are made to the device or product labeling. Therefore, the NeuroStar TMS Therapy System with this change to the product labeling is substantially equivalent to the predicate device.

#### Clinical Performance:

A database search was conducted to identify human studies evaluating TMS and variations in inter-train interval. This analysis encompassed 79 studies and research outcomes on 3359 subjects, among whom 2162 subjects were exposed to active TMS treatment. Data from these studies were used to analyze the safety and effectiveness of TMS delivered using varying TMS treatment parameters, particularly varying inter-train intervals. The analysis of effectiveness was conducted using the results of 44 studies (a total of 50 active treatment arms) where there was complete information to identify the TMS treatment parameter set used and the clinical outcome for the primary efficacy measure. In addition to reviewing the data from clinical trials, the evidence summarized in four peer-reviewed meta-analyses of the efficacy of TMS for the treatment of major depressive disorder was also examined. Eleven clinical studies utilized the NeuroStar TMS Therapy System or progenitor iron-core devices and encompassed 1069 subjects, among whom 770 subjects received active TMS. The remaining studies used reference TMS devices. This analysis showed that variations across the range of inter-train intervals used within the reported treatment parameter sets do not impact TMS efficacy.

For safety analysis, when provided, adverse events using the verbatim terms used in the reference were aggregated. The sporadic incidence of seizure was also evaluated. These data represent summary evidence from 61 studies, comprising 67 active treatment arms among 2836 subjects. This analysis showed that there is no evidence to indicate that the risk of inadvertent seizure or the pattern of common adverse events reported for TMS varies in a systematic manner across the range of inter-train intervals used within the reported treatment parameter sets.

The NeuroStar TMS Therapy System that is the subject of this premarket 510(k) notification is the same (substantially equivalent) device cleared by the FDA under DEN070003/K061053, K083538, K130233 and K133408. New clinical data from a literature review of clinical trials conducted for the NeuroStar TMS Therapy System and reference TMS devices demonstrate that the revised inter-train interval range does not impact the safety and efficacy of the NeuroStar TMS Therapy System for its indicated use.
