About this study

Official title: Economic Evaluation of Treatment Modalities for Position Dependent Obstructive Sleep Apnea Patients

OBJECTIVES:

To evaluate the effect and cost-utility of a combination therapy of SPT+MAD compared with continuous positive airway pressure (CPAP) in patients with moderate positional obstructive sleep apnea (POSA).

Read more

HYPOTHESIS:

The SPT+MAD combination is more cost-effective and effective, in means of reduction of the apnea-hypopnea index (AHI), quality of life and compliance, compared with CPAP.

STUDY DESIGN:

A multicenter randomized clinical trial (RCT) will be performed with a follow-up of 12 months per patient. Patients will be randomized for CPAP or the combination SPT and MRA. All outcomes will be measured at baseline, month 3, 6 and 12.

STUDY POPULATION:

Patients diagnosed with moderate POSA according to polysomnography (PSG) results.

INTERVENTION / STANDARD INTERVENTION TO BE COMPARED TO:

The SPT trains POSA patients to sleep in non-supine positions, CPAP uses positive airway pressure to open the airway; MRA is an intra-oral prosthesis, which holds the mandible in a protrusive position, all to prevent effectively apneic events.

OUTCOME MEASURES:

AHI, compliance, quality-adjusted life year (QALY), direct and indirect costs, cardiovascular parameters, incremental cost-effectiveness ratio (ICER)

SAMPLE SIZE / DATA ANALYSIS:

100 subjects in each treatment group, total of 200 patients.

COST-EFFECTIVENESS ANALYSIS / BUDGET IMPACT ANALYSIS:

The SPT is expected to improve the cost-effectiveness of overall treatment of POSA patients, and will save annually approximately 35-150 million euros.

Study groups in NCT02553902
Study groupRoleWhat they receive
Combination therapyActive comparatorSleep Position Trainer + Mandibular Advancement device combination The SPT is a sensor that measures the sleeping position, and gives the user feedback about wrong positions with a soft vibration. A user is then able to react to the signal and turn into a non-supine position. To stimulate compliance, information is provided about nightly behaviour, implicating a learning pattern by viewing the data on a home computer. MRA or oral appliances (OA) works by advancing the mandible and its attached soft tissue structures forward they aim to increase upper airway size.
Receives: Device: Sleep position trainer; Device: Mandibular advancement device
CPAPContinuous positive airway pressureActive comparatorContinuous positive airway pressure (CPAP) functions as a pneumatic splint to maintain upper airway patency. Possible side effect can be related to the interface, pressure and negative social factors.
Receives: Device: Continuous positive airway pressure

Questions about this trial

What is this clinical trial studying?

A study testing Sleep position trainer, Mandibular advancement device and Continuous positive airway pressure in people with Positional Obstructive Sleep Apnea, run by Onze Lieve Vrouwe Gasthuis at 2 sites in 2 countries.

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 8 inclusion and 14 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 11 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Belgium, Netherlands. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Patty Vonk, MD (researchkno@olvg.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Apnea-hypopnea index (AHI) (time frame: change from baseline, after 3, 6 and 12 months). 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?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Apr 2018.
