Indications for Use
The Night Shift is indicated for prescription use for the treatment of adult patients with positional obstructive sleep apnea with a non-supine apnea-hypopnea index < 20, and to reduce or alleviate snoring. It records position, movement, and sound so that positional changes in sleep quality and snoring can be assessed.
Device Story
Night Shift is a neck-worn device for positional obstructive sleep apnea (OSA) treatment. It uses 3-D actigraphy and an acoustic microphone to monitor sleep position, movement, and snoring. When the device detects the user in a supine position, it initiates vibro-tactile feedback via haptic motors, increasing in intensity until the user shifts to a non-supine position. The device is used at home by the patient. Data is stored on the device and can be transferred via USB to a web portal or desktop software for report generation, allowing users and clinicians to assess sleep quality, snoring levels, and therapy efficacy. The device helps patients avoid supine sleep, potentially reducing apnea events and snoring.
Clinical Evidence
Clinical study of 27 patients with positional OSA (non-supine AHI < 20). Primary endpoint: 85.2% of participants achieved >50% reduction in AHI. Secondary endpoints met: 92% accuracy in supine position detection (vs. video/chest sensor), 100% compliance (min 20/28 nights), and significant improvements in snoring. No adverse events reported. Bench testing confirmed electrical safety (IEC 60601-1), EMC (IEC 60601-1-2), and biocompatibility (ISO 10993-1).
Technological Characteristics
Neck-worn device with silicone enclosure. Sensing: 3-D actigraphy and acoustic microphone. Actuation: Haptic motors for vibro-tactile feedback. Connectivity: USB for data transfer to web portal/desktop software. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, ISO 10993-1. Cleaning: Alcohol wipes/detergent. Firmware-based control.
Indications for Use
Indicated for adult patients with positional obstructive sleep apnea (non-supine AHI < 20) and to reduce or alleviate snoring.
Regulatory Classification

## DEVICE DESCRIPTION:
The Night Shift is worn around the neck to reduce the amount of time the user sleeps in the supine position as a treatment for positional obstructive sleep apnea. Night Shift combines hardware and firmware to detect when the user attempts to sleep in the supine position and can initiate vibro-tactile feedback with increasing intensity until the user shifts to a non-supine position. The initiation of positional feedback from the Night Shift is turned on is programmable to allow the user to fall asleep (if they must) on their back. Each night the Night Shift is worn, it monitors sleep position (% time supine), behavioral sleep efficiency, and snoring levels (% time snoring > 40 and 50 dB) as well as the frequency, duration and intensity of the feedback (when applied). These data can be optionally transferred via the USB port to the Night Shift Web Portal where the user can generate a report to assess how well the positional feedback is working. A "trial" protocol can include one night with no feedback to establish a baseline and two nights with feedback to assess compliance/efficacy. Utilization information is saved on the device that allows reports to be generated that compares daily use by month and monthly averages for one year. The portal also allows the device to be reformatted (to eliminate all previously recorded data) for a new user, adjust the feedback settings to a new user's personal preferences, and/or upgrade the firmware. For large healthcare organizations that limit internet access, desktop software is provided as an alternative to the portal.
#### INTENDED USE:
The Night Shift is indicated for prescription use for the treatment of adult patients with positional obstructive sleep apnea with a non-supine apnea-hypopnea index < 20, and to reduce or alleviate snoring. It records position, movement, and sound so that positional changes in sleep quality and snoring can be assessed.
#### TECHNOLOGY:
The Night Shift uses the same fundamental technology as a therapeutic massager (i.e., regulation number 890.5975) to deliver vibro-tactile feedback with haptic motors when the user attempts to sleep on their back. The Night Shift is functionally equivalent to the ZZOMA positional sleeper as both devices prevent users from sleeping on his or her back. The Night Shift provides information used to assess user benefit by recording position, movement, snoring and feedback frequency and duration using the actigraphy and acoustic microphone signals equivalent to Apnea Risk Evaluation System. The technologies used in the Night Shift are used in the same manner as the predicate products and do not raise new questions of safety and effectiveness.
Table 5.1 summarizes the similarities and differences of the Night Shift to the legally marketed predicate devices to which substantial equivalency is claimed. The Night Shift is equivalent to the ZZOMA Sleep Positioner (K100160) for treatment of positional OSA and equivalent to the

Additional verification and validation testing confirmed:
- All features of the Night Shift were compliant with the system, software and firmware . level requirements.
- . Night Shift provides information useful in assessing user benefit equivalent to the predicate device.
## SUMMARY OF CLINICAL TESTS:
A clinical study was conducted to evaluate safety and efficacy of the Night Shift. For this evaluation, patients who had completed a baseline PSG with a minimum of four hours of sleep time were to wear the Night Shift for two nights without feedback to confirm their willingness to continue with the study, followed by 28 nights of vibro-tactile position therapy. A follow-up PSG was conducted as soon as possible to the completion of the 28-nights of treatment.
With respect to effectiveness of Night Shift therapy, the following primary endpoint was evaluated: 65% of positional therapy (PT) compliant participants with baseline overall AH > 10 will demonstrate a clinically important reduction in sleep apnea severity based on a minimum 50% reduction. The indication for use for Night Shift was further refined to include only those patients with a non-supine AHI <20. Results from 27 patients with pre-treatment positional obstructive sleep apnea with a non-supine AHI < 20 were included in the analysis. They are stratified by outcome and the post-treatment overall AHI in the table below. This analysis confirms that the primary endpoint was met and that Night Shift is efficacious in the treatment of patients with positional obstructive sleep apnea (POSA) with a non-supine AHI <20.
| | Pre-treatment | | | 95% Confidence | |
|--------------------------|---------------|--------------|-----------|----------------|--------------|
| | >5 AHI <15 | >15 AHI < 30 | AHI > 30 | Total | Interval |
| Treatment outcome | n = 11 | n = 10 | n = 6 | n =27 | |
| AHI >50% decrease, % (n) | 81.8 (9) | 80.0 (8) | 100.0 (6) | 85.2 (23) | 71.8 – 98.6 |
| AHI >35% decrease, % (n) | 9.1 (1) | 0.0 (0) | 0.0 (0) | 3.7 (1) | -3.4 - 10.8 |
| Non-responder, % (n) | 9.1 (1) | 20.0 (2) | 0.0 (0) | 11.1 (3) | -0.8 -- 23.0 |
In addition to the primary endpoint discussed above, the study evaluated the following additional primary, secondary and exploratory endpoints. For these endpoints, the analysis includes an additional 3 subjects that were part of the full study but had a pre-study non-supine AHI >20 and were therefore outside of the indication evaluated for effectiveness.

| Primary Endpoints | | |
| 80% of participants will complete the<br>study with no adverse events resulting<br>in him/her voluntarily dropping from<br>the Study (primary) | 100% of the subjects who were<br>provided an intention to treat and<br>were compliant with the protocol<br>successfully completed the study.<br>No adverse events were reported. | The primary endpoint is met. |
| Secondary Endpoints | | |
| Night Shift will accurately measure<br>the supine position such that the<br>computation of percent time supine<br>by Night Shift is within+/- 5% of the<br>percent time supine by video<br>recordings plus chest sensor in 73% of<br>subjects. | Night Shift was within 5% of<br>chest/video supine time in 92% of<br>the studies. | The secondary endpoint is met. |
| At least 80% of participants will be<br>compliant i.e., use Night Shift for a<br>minimum of 5.5 hours/night or the<br>length of their time in bed, five .<br>nights/week (e.g., 20 of 28 nights). | 100% of the participants wore the<br>Night Shift for a minimum of 20<br>nights across the 28 nights of<br>intended use. | The secondary endpoint is met. |
| At least 70% of participants will<br>average less than 15% time supine<br>across the four weeks of home use. | 97% of the participants averaged<br>less than 15% of time in bed in the<br>supine position when therapy was<br>delivery. | The secondary endpoint is met. |
| 50% of PT compliant participants will<br>show an improved Epworth<br>Sleepiness Score (ESS) of $≥$ 2. | 50% of participants exhibited an<br>improvement of 2 or more, and<br>50% showed no change. None of<br>the ESS scores worsened by 2 or<br>more. | The secondary endpoint is met. |
| The Functional Outcomes of Sleep<br>(FOSQ) total will improve by $≥$ 2 points<br>in at least 50% of subjects. | 57% exhibited an improvement of 2<br>or more, 23% showed no change,<br>and 20% showed a worsening of 2<br>or more. | The secondary endpoint is met. |
| The mean sensitivity (sleep) and<br>specificity (wake) for Night Shift will<br>be 0.85 and 0.50, respectively. | The endpoint was met based on the<br>sensitivity and specificity of 90%<br>and 58% across 65 studies. | The secondary endpoint is met. |
| Endpoint | Study Result | Conclusion |
| 73% of subjects will be within the<br>range of the predicate when<br>subtracting PSG Total Sleep Time (TST)<br>from Night Shift TST (i.e., range 151<br>and -129 minutes, respectively). | 99% of the studies had TST derived<br>from Night Shift within the<br>maximum error (based on two<br>standard deviations of the TST error<br>for the predicate device) vs. PSG<br>TST. | The secondary endpoint is met. |
| 73% of subjects will be within the<br>range of the predicate when<br>subtracting PSG Sleep Efficiency (SE)<br>from Night Shift SE (i.e., range 19.1<br>and -17.2%, respectively). | 92% of studies had SE values<br>derived from Night Shift within the<br>maximum error (based on two<br>standard deviations of the SE error<br>for the predicate device) vs. PSG SE.<br>80% of subjects had sleep onset<br>values <15-minutes. 82% of<br>subjects had wake after sleep onset<br>(WASO) values <45 minutes | The secondary endpoint is met. |
| Exploratory Endpoints | | |
| There are no consistent patterns of<br>increased N1 and cortical arousals or<br>decreased N3 and REM. | 87% showed in decrease in N1, 80%<br>a decrease in cortical arousals, 17%<br>an increase in N3, and 33% an<br>increase in REM sleep.<br>Only 3% of subjects showed<br>increase in N1, 7% an increase in<br>cortical arousals, 13% a decrease in<br>N3, and 17% a decrease in REM<br>sleep. | The exploratory endpoint is met. |
| The percent time snoring > 50 dB can<br>be used to identify patients with an<br>AHI ≥ 10 with a sensitivity > 0.80 and a<br>specificity > 0.65 so that these Night<br>Shift users will recognize the need to<br>be evaluated for undiagnosed<br>obstructive sleep apnea. | When the percentage of time<br>snoring above 50 dB exceeds 10%<br>of sleep time, the sensitivity was<br>0.85 and the specificity exceeded<br>0.58. | The exploratory endpoint was not<br>met. |
| Supplemental analysis | Statistically significant<br>improvements in loud snoring was<br>observed. Loud snoring decreased<br>in 59% of subjects, and only<br>increased in 10% of the cases. | |
| Endpoint | Study Result | Conclusion |
| Those successfully or unsuccessfully<br>treated with Night Shift can be<br>identified via combination of changes<br>in the AHI, daytime drowsiness (ESS),<br>depression (PHQ9), Insomnia (ISI),<br>anxiety (GAD7) and quality of life<br>(FOSQ). | Evaluating trends across these<br>measures, 50% of subjects showed<br>a substantial improvement as a<br>result of Night Shift therapy and an<br>additional 10% showed<br>improvement, and 33% showed no<br>change. None showed a worsening<br>and two cases (7%) showed<br>substantial overall worsening of<br>subjective measures. There was no<br>consistent patterns which can be<br>used to identify those who would<br>likely benefit from therapy, in part,<br>because most subjects benefited<br>either physiologically,<br>symptomatically or both. There<br>was some evidence to suggest that<br>limited time in-home untreated in<br>the supine position was associated<br>with no change in subjective<br>measures. | This exploratory endpoint was<br>suggested by the FDA under the<br>assumption that there would be<br>treatment failures and it would be<br>beneficial to a clinician to identify<br>patterns which define treatment<br>success/ failure.<br>In this study, the numbers of<br>failures were too few to<br>characterize. |
