Intended Use

The eNeura Inc. SpringTMS® is indicated for the acute and prophylactic treatment of migraine headache.

Device Story

SpringTMS is a portable, hand-held device for single pulse transcranial magnetic stimulation (sTMS). It delivers a brief, 0.9 Tesla magnetic pulse to the occipital cortex to induce electrical currents, aiming to stop or reduce migraine effects. Designed for patient self-administration in home or office settings. Treatment regimen involves daily prophylactic pulses (4 pulses morning/evening) and acute treatment (3 pulses at onset, repeatable). Device is prescription-only. Healthcare providers use clinical outcomes to monitor treatment efficacy. Benefits include reduction in migraine headache days and decreased reliance on acute medications.

Clinical Evidence

Prospective, multicenter, non-randomized, single-arm observational study (ESPOUSE) with 217 subjects (Safety Data Set). Primary endpoint: mean reduction in migraine headache days over 28 days at 12 weeks. Results showed statistically significant reduction of 2.8 days (FAS, p<0.0001) and 3.0 days (PP, p<0.0001) from baseline. No serious adverse events reported; common AEs included lightheadedness, dizziness, tinnitus, and scalp discomfort.

Technological Characteristics

Portable, hand-held transcranial magnetic stimulator. Delivers 0.9 Tesla single magnetic pulse. Operates via electromagnetic induction to stimulate the occipital cortex. Class II device, Product Code OKP. Contraindicated for patients with metal-containing implants in the head, neck, or upper body (e.g., aneurysm clips, cochlear implants, shunts, stents, metal plates/screws).

Indications for Use

Indicated for acute and prophylactic treatment of migraine headache in patients 18 to 65 years of age with migraine with or without aura.

| Study Design | A prospective, non-randomized, single arm, multi-center observational<br>study designed to evaluate the use of the SpringTMS system in<br>reducing the frequency of headache days against a performance goal. | |
| Number of<br>Patients | A total of 263 subjects were consented between December 2014 and<br>March 2016. 229 of these subjects completed a Baseline Diary and 220<br>were confirmed by the sites to be eligible for participation. There were<br>217 subjects that were assigned Spring TMS devices and these subjects<br>comprise the Safety Data Set. There were 179 subjects who began<br>treatment and completed a Month 1 treatment Diary, but 47 of these<br>subjects did not meet the definition of a Migraine Headache Day<br>(minimum requirement of at least 4 days with moderate to severe<br>headache pain for at least 4 hours at baseline). Thus 132 of these subjects<br>complied with the protocol requirements based upon headache day<br>definition. This was the Full-Analysis Data Set (FAS) described below.<br>There were 117 of these subjects that went on to finish treatment and<br>completed both baseline and Month 3 diaries. This was the Completed<br>Cases data set (CC). Of these subjects 95 complied with the protocol<br>instructions regarding use of the device. This was the per Protocol (PP)<br>data set. | |
| Number of Sites | Seven (7) | |
| Duration of Trial | Each provisionally enrolled subject was followed for 1 month (28±5<br>days) to establish a baseline number of headache days (HD) and<br>confirm final eligibility and then each confirmed enrolled patient was<br>followed for 3 consecutive months (12±1 weeks) of treatment followed<br>by a final assessment. | |
| Treatment | Patients were instructed to treat daily using the following protocol: | |
| Regimen | 1. From the start, treat with 4 Pulses each morning and evening:<br>2 consecutive pulses wait 15 minutes and repeat the 2<br>consecutive pulses. | |
| | 2. Additionally, the patient may treat an acute attack with:<br>3 sequential pulses (early) at the onset of migraine pain<br>Wait 15 minutes, if needed treat with additional 3 pulses<br>Wait 15 minutes, if needed treat with additional 3 pulses<br>Patients may rescue with acute medication 30 minutes after the first<br>three pulses are delivered. | |
| Performance Goal | The originally proposed performance goal for the primary endpoint,<br>representing the mean reduction in headache days for a controlled<br>study, assumed an approximate 80% chronic headache population and<br>was PGMD = -5.3 days. | |
| | This performance goal was amended ahead of un-blinding and the<br>final analysis to PGD=-0.633 in order to reflect the actual population of<br>~20% chronic and ~80% episodic enrollment. | |
| Primary<br>Effectiveness<br>Endpoint | Mean reduction in headache days over a 28-day period at 12±1 weeks<br>(i.e., weeks 9 through 12 from start of treatment period). The null and<br>alternative hypotheses for this endpoint are: | |
| | H0: $μ$ T ≥ PGMD versus Ha: $μ$ T < PGD | |
| | PGD = - 0.633 days. | |
| | where $μ$ T is the mean reduction in migraine headache days from<br>baseline at 12±1 weeks in the treated population and PGD is the<br>Performance Goal. | |
| | Headache day is defined as ≥4 hours of headache pain which at any<br>time reaches moderate or severe intensity. | |
| Secondary<br>Effectiveness<br>Endpoints | 1. The percentage of subjects who had at least a 50% reduction in<br>headache days | |
| | 2. The reduction from baseline in the days of medications use to<br>acutely treat migraine headaches | |
| | 3. The reduction from baseline in the HIT6 impact questionnaire | |
| | 4. The reduction from baseline in the days with headache for more<br>than 4 hours with any pain intensity | |
| | 5. Migraine is defined as >4 hours of headache pain which at any<br>time reached moderate or severe intensity. | |
| Primary Safety<br>Endpoint | The proportion of patients experiencing any adverse event in aggregate<br>and by event. | |
| Inclusion Criteria | 1. Patients 18 to 65 years of age; | |
| | 2. Patients able to understand and communicate in English; | |
| | 3. Migraine with or without aura; | |
| | 4. 4-25 headache days per month (confirmed by 1-month baseline<br>diary, minimum of 5 complete headache-free days/month); | |
