Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a safety and efficacy trial for a Slow Wave, Inc. UASD oral appliance for the treatment of Obstructive Sleep Apnea. This trial will recruit 60-80 participants through our IRB partner. Each participant will take pre-trial and post trail sleep studies and be measured before, throughout and after the trial for Apnea-Hypopnea Index (AHI), Oxygen Desaturation Index (ODI), pulse rate to determine level of sleep improvement while wearing the device. Safety will also be measured through survey, dental exams and adverse events monitoring. Patients will wear an O2 monitoring ring throughout the study and upload results daily. Primary Objectives will evaluate AHI and ODI between sleep studies. Secondary outcomes will compare the daily ring data to these two sleep studies to evaluate changes over time. Patients will have the opportunity to complete daily diaries on their sleep experiences.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is a single-center, single-arm open label study to evaluate the safety and effectiveness of the Slow Wave UASD sleep and snore device in individuals with mild-to-moderate Obstructive Sleep Apnea (OSA) and individuals with severe OSA of less than 40 AHI events per hour who are not able to tolerate CPAP treatment.

All participants will be given and initial Home Sleep Apnea Test (HSAT) to establish baseline readings for: Number of OSA events during sleep, average O2 score during sleep, average pulse rate and Oxygen desaturation events of more than 4% during sleep (ODI). The initial HSAT will also determine if the patients have OSA.

All participants will get an intraoral scan with a closed bite by a study partner. The 3D scan will be used to create a personalized Slow Wave UASD device that will be used throughout the study. Each participant will wear the device for a 90-day period. Each participant will be given a WellUE O2 ring to wear every night throughout the study. The ring connects to the WellUE application that participants will be asked to download to their phones. The O2 ring application collects much of hte same data as is collected in a home sleep study. Participants will be asked to upload the ring results to a study-managed database on a daily basis. Ring results will be presented as secondary objectives in this trial. The failure of a participant to send ring data will not disqualify them from the trial as primary objectives are the comparison of beginning and ending HSAT results. Patients will be given patient health questionnaires and physical examinations prior to participation.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* • Provision of signed and dated informed consent form

* Unable to tolerate or decline positive airway pressure therapy
* Absence of markedly enlarged tonsils, defined as 3+ or 4+ according to the Brodsky classification
* Able to protrude tongue ≥20mm beyond maxillary incisors
* No uncontrolled nasal obstruction (must be able to breathe through nose)
* Stable medication regimen for ≥1 month
* Stated willingness to comply with all study procedures and availability for the duration of the study
* Male or female, of any race, aged 18-70 years (inclusive)
* If diagnosed with uncomplicated Mild to moderate, moderate to severe OSA (i.e., AHI \>5, \<30 h-1); where uncomplicated is defined by the absence of:

* Conditions that place the patient at increased risk of non-obstructive sleep-disordered breathing (e.g., central sleep apnea, hypoventilation, and sleep-related hypoxemia). Examples of such conditions include significant cardiopulmonary disease, potential respiratory muscles weakness due to neuromuscular conditions, history of stroke, and chronic opiate medication use.
* Concern for significant non-respiratory sleep disorder(s) that require evaluation (e.g., disorders of central hypersomnolence, parasomnias, sleep-related movement disorders) or interfere with accuracy of HSAT (e.g., severe insomnia).
* Environmental or personal factors that preclude the adequate acquisition and interpretation of data from HSAT.
* Body mass index (BMI) \< 35 kg/m2
* Neck circumference \< 45 cm
* Absence of severe oxyhemoglobin desaturation during sleep, indicated by mean nocturnal SpO2 \> 82%
* Mandibular range of motion \> 5 mm in protrusive direction
* Adequate dentition, as determined by the site dentist
* Must have a smart phone able to download 02 ring app

Exclusion Criteria

* • Inability to breathe through the nose comfortably

* Presence of \> 25% Central Sleep Apnea (CSA)
* Severe OSA above AHI \>40
* Uncontrolled sleep disorder such as narcolepsy, chronic insomnia, restless legs syndrome, or REM behavior disorder
* Presence of positional obstructive sleep apnea per Cartwright's definition (Ratio of respiratory events in the supine to nonsupine position greater than 2:1)

* Use of CPAP or OAT within the two weeks prior to the screening HSAT
* Anticipated change in medical therapy during the study protocol that could alter OSA severity (e.g., weight loss surgeries; UPPP, MMA, tongue/hyoid suspension)
* Loose teeth or advanced periodontal disease
