About this study

Official title: A New Objective Titration Procedure Using Remotely Intelligent Sleep Monitoring System for the Treatment of Mandibular Advancement Device in OSAHS Patients

The aim of this clinical trial is to apply a new objective titration procedure in obstructive sleep apnea hypopnea syndrome (OSAHS) patients treated with mandibular advancement device (MAD), and to compare this new objective titration procedure with the subjective titration procedure which is commonly used in clinical practice. The remotely intelligent sleep monitoring system (RISMS) will be used in the new objective titration procedure. The main questions it aims to answer are:

  1. The efficacy of MAD therapy after each titration procedure.
  2. The titration time efficiency and the improvement of subjective symptoms after each titration procedure.
Read the detailed description

In this study, patients diagnosed with OSAHS and referred for MAD treatment will be recruited. The amount of mandibular protrusion seems to be a key factor in the treatment of MAD. Patients will experience either of the two titration procedures to obtain the optimal mandibular protrusion. One procedure is a new objective titration procedure which will use the RISMS for the treatment of MAD, which will help the clinician instruct the titration according the objective therapeutic indicator. The other procedure is the subjective titration procedure which is commonly used in clinical practice. Finally, the researchers will compare the efficacy of the MAD therapy, the titration time efficiency and the improvement of subjective symptoms between the two titration procedures.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • titration procedure for MAD treatmentProcedure or surgery

    The OSAHS patients referred for MAD treatment will experience either the objective titration procedure or the subjective titration procedure.

Study groups in NCT06424405
Study groupRoleWhat they receive
objective titration procedureExperimentalObjective titration procedure will be based on the objective diagnosis and treatment indicator AHI(Apnea-hypopnea index)which will be provided by RISMS (Remotely intelligent sleep monitoring system). SC-500TM is a comfortable contactless under-mattress sleep monitor, as a main component of the RISMS will be given to patients to collect the sleep data every night at home setting. The sleep report will be generated automatically every day providing the value of AHI and uploaded to the clinicians in real-time. The clinicians will contact the patients by phone every 3-7 days and instruct them remotely to adjust the MAD to increase the mandibular advancement by 0.25-1mm each time, according to AHI together with the self-reported evolution of symptoms. The patients will adapt this new mandibular advancement for 3-7 days and the clinicians will contact them again for further adjustment until a significant improvement of AHI and resolution of symptoms occurs.
Receives: Procedure: titration procedure for MAD treatment
subjective titration procedureActive comparatorThe subjective titration procedure in this study will be based on self-reported evolution of symptoms and physical limits of the OSAHS patients. Patients will be recalled to the hospital every 1-2 weeks and will be asked about the subjective changes such as snoring, daytime sleepiness,ache of tooth, temporomandibular pain and so on. Then, the clinicians will adjust the MAD to increase degree of mandibular advancement by 0.5-1mm each time. The patients will adapt this new mandibular advancement for 1-2 weeks and have to come back to hospital for further adjustment until an improvement or a resolution of symptoms occurs, or until the patients could not tolerate any further advancement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. efficacy of MAD therapy

    The efficacy of MAD therapy is in terms of AHI (Apnea-hypopnea index) reduction compared to baseline, as well as the number of responders defined as patients with a reduction in AHI of 50% or more compared to baseline, and/or a follow-up AHI of 10 events/hour or less.

    Measured: The parameter of AHI will be recorded at baseline before the titration and the end of the titration procedures (up to 60 days) using the same PSG device to diagnose OSAHS.

Secondary outcomes (3)
  1. titration time efficiency

    The titration time efficiency is the percentage of saved time over the prescribed time.

    Measured: The prescribed time is 60 days. The actual titration time is the time taken from the start to the end of the titration procedures (up to 60 days). The saved time is 60 days minus actual titration day.

  2. Epworth sleepiness score(ESS)

    The ESS (Epworth Sleepiness Scale) is a self-administered questionnaire that evaluates subjective daytime sleepiness in quotidian situations. The score ranges from 0 to 24 and is usually elevated in sleep apnea patients, indicating a propensity to fall asleep. The score 0 means no sleepiness at daytime, and the score 24 means serious sleepiness. Lower scores mean a better treatment outcome.

    Measured: ESS will be determined at baseline and the end of titration procedures (up to 60 days).

  3. Snore Scale(SS)

    SS (Snore Scale) is measured by A 10-point visual analogue scale (VAS) to assess the severity of snoring, with the VAS ranging from 0, representing no snoring, to 10, causing the bed partner to leave the room or sleep separately. Lower scores mean a better treatment outcome.

    Measured: SS will be determined at baseline and the end of titration procedures (up to 60 days).

Questions about this trial

What is this clinical trial studying?

A study testing titration procedure for MAD treatment in people with Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS), run by Beijing Jishuitan Hospital at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 22 May 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

What does the primary outcome measure?

efficacy of MAD therapy (time frame: The parameter of AHI will be recorded at baseline before the titration and the end of the titration procedures (up to 60 days) using the same PSG device to diagnose OSAHS.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
