Mandibular Advancement Device (MAD) in Pregnant Women With Obstructive Sleep Apnea (OSA) (OBMAD)

January 27, 2025 updated by: Henry Ford Health System

Mandibular Advancement Device (MAD) as an Alternative Treatment Option in Pregnant Women With Obstructive Sleep Apnea (OSA)

We propose a single-arm trial to test the patient uptake and preliminary efficacy of MAD in a sample of 10 pregnant women with mild-to-moderate OSA. Study outcomes include patient-reported symptoms and objectively assessed sleep parameters assessed before treatment, during and after 10 weeks of MAD intervention (during pregnancy) and postpartum.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to explore MAD as an alternative treatment option for OSA in pregnant women. We are recruiting a small number of 10 healthy pregnant women with uncomplicated OSA (absence of significant cardiovascular, metabolic or neurocognitive consequences) who, after being offered CPAP as the recommended standard treatment, prefer to use a MAD over CPAP. All patients are recruited from a single center. We would like to get a first impression on the comfort level of these women with the MAD and their self-reported compliance and any improvement of symptoms with treatment. Additionally, we would like to test efficacy in controlling OSA with pregnancy progression. Finally, we would like to derive overall treatment effectiveness of the MAD in pregnant women as defined as a combination of efficacy and compliance.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Singleton pregnancy, gestational week 14-20.
  2. Age ≥ 18, English-speaking.
  3. Reliable internet access (questionnaires/surveys)
  4. Untreated mild to mild-moderate OSA defined as AHI between 5-20 events/hour on the most recent home sleep study
  5. No significant hypoxemia on the initial sleep study defined as SaO2 nadir ≥70% and SaO2 equal or less than 30 minutes ≥88%
  6. The sleep study must have been a home sleep test that uses Peripheral Arterial Tone signal for evaluation of apneic events. The home sleep test has to be a WatchPAT device (WatchPAT® Home Sleep Study Device | Itamar Medical Ltd.).

  9. Good oral health with manual dexterity and at least 8 tooth per arch

Exclusion Criteria:

  1. High risk pregnancy (age >40y, superimposed preeclampsia, pre-existing cardiac disease, severe organ dysfunction such as liver or renal failure, any condition that requires anticoagulation), and any condition Dr. Pitts or Dr Smith deem serious risk to mother/fetus. Well controlled chronic hypertension and diabetes are allowed and will not be excluded.
  2. Dental exclusion criteria: Complete edentulous arch, ongoing oral rehabilitation, uncontrolled periodontal disease, ongoing orthodontic treatment or completed treatment in a period less than 5 years, temporomandibular dysfunction (active acute pain or limitations on mandibula movements of any kind), prior oropharyngeal surgery, maximum protrusion less 5 mm
  3. Significant acute health problems that are unrelated to pregnancy or dental diseases including unstable psychiatric disease
  4. Non-English speaking

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Intervention
Device: Mandibular advancement Device
Intra oral appliances and more specifically Mandibular Advance Devices (MAD) are one of the established alternatives to treat OSA. Oral appliances and MAD are often used interchangeably but we prefer to call them MAD as it is more descriptive of its mechanism of action. MAD are placed in the mouth to temporarily advance and stabilize the lower jaw forward in order to keep the airway open during sleep.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Describe patient uptake of MAD
Time Frame: 9 months
MAD adherence will be determined via patient-reported sleep diaries during the first 10-weeks of MAD intervention according to the AADSM guidelines. Specifically, patients will report each morning whether they wore their MAD and to estimate how long they wore it for. Consistent with Medicare guidelines for PAP therapy, we will operationalize compliance as wearing the device for ≥4 hrs each night for 70% of nights. We will describe compliance rates.
9 months
Evaluate preliminary efficacy of MAD for treating mild-to-moderate OSA
Time Frame: 9 months
We will assess AHI before treatment (T1), after 10 weeks of MAD treatment during pregnancy (T2), and then finally three months after childbirth (T3) via home sleep tests used in our sleep clinic per standard care. We hypothesize that AHI at T2 and T3 will be significantly lower than T1. For descriptive purposes, we will report rates of OSA remission (AHI<5) at T2 and T3 as well as rates of positive treatment response operationalized as a ≥50% reduction in AHI from T1.
9 months
Test for changes in patient-reported symptoms.
Time Frame: 9 months
OSA is associated with increased fatigue and sleepiness. We hypothesize that patients will report lower levels of fatigue and daytime sleepiness at T2 and T3 relative to T1 baseline.
