About this study

Official title: Inspire® Upper Airway Stimulation System: Randomized Control Trial / European Post-Market Study

The purpose of this post-market study is to assess safety and effectiveness of Inspire Upper Airway System (UAS) in a commercial setting. This study will provide additional clinical evidence of Inspire UAS for treatment of moderate to severe obstructive sleep apnea (OSA) using a randomized controlled trial design.

Read the detailed description

This study is a prospective, multi-center, randomized controlled study with a delayed start arm, conducted under a common implant protocol.

Up to 40 study subjects will be implanted at up to six centers in Europe. Subjects will be evaluated at baseline, implant, post-op (randomized) and 1-, 2-, 3,- 4- and 6-months post-implant.

Baseline data will include collection of demographics and medical history, completion of a physical exam, Functional Tongue Exam (FTE), and subject quality of life (QoL) questionnaires (Functional Outcomes of Sleep Questionnaire (FOSQ) and Epworth Sleepiness Scale (ESS)). Adverse event data will be collected from the time of baseline testing through the 6-month study follow-up.

Implant eligibility assessments will include home sleep testing (HST), a surgical consultation and a drug induced sedated endoscopy (DISE) to determine if the subject is a qualified candidate for implant.

Subjects meeting all baseline and pre-screening requirements will be implanted with the Inspire system. Intra- and post- operative procedure data will be collected. Subjects will be seen for a post-operative check one week after implant. During this visit, subjects will be randomized 1:1 to the ACTIVE group or the DELAY group. However, the Inspire system will not be activated (turned "on") during the first month post-implant to allow for post-surgical healing.

Only subjects randomized to the ACTIVE group will return for the 1-month follow-up visit at which time the device will be activated (turned "on"). The subjects will be provided with a patient remote and instructed on its use. These ACTIVE arm subjects will be instructed to use their Inspire system on a nightly basis and return for a 2-month visit for an in-laboratory sleep study to complete device titration.

All subjects (ACTIVE and DELAY) return for the 3-month visit to complete a HST (DELAY subjects' therapy will remain off during the HST). In addition, QoL and patient satisfaction surveys, Functional Tongue Exam (FTE), and general health assessments, including adverse event review, will be collected. Subjects in the DELAY arm will have their therapy activated at the end of the 3 month visit, and return for a 4-month visit for an in-laboratory sleep study to complete device titration. All subjects will return for a 6-month and final visit where a two-night HST will be completed. In addition, QoL and patient satisfaction surveys, physical exam and FTE data will be collected; a device check will be completed as well as adverse event review. Therapy usage and device adjustment data, as well as a subject satisfaction with therapy survey, will be collected for additional analysis. Safety data will be collected throughout the study.

What participants receive

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

  • Inspire® Upper Airway Stimulation (UAS) SystemDevice

    Also called Inspire® Therapy

    This is a single-arm study; all participants will be implanted with the Inspire® Upper Airway Stimulation (UAS) System. This is a permanent, implantable therapy device, which consists of three implantable components: an implantable pulse generator (IPG), a stimulation lead, and a sensing lead. In addition, the patient receives a handheld remote to activate the therapy

What is being measured

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

  1. Change from Baseline OSA at 3 Months

    The percent of apnea hypopnea index (AHI) reduction will be used as a primary endpoint to quantify the effects of the Inspire therapy on OSA between the 'Active' therapy (ACTIVE) and 'Delayed Start' therapy (DELAY). The percent of AHI reduction is the percent change between baseline AHI at the pre-implant sleep study and AHI at the 3-month post-implant sleep study.

    Measured: 3 months post-implant

Secondary outcomes (4)
  1. Number of Reported SAEs / Procedure & Device Related AEs

    Safety of the therapy will be assessed via the description of all reported SAEs and all procedure- or device-related AEs. Adverse events will be summarized by seriousness, severity, relatedness to the device and/or procedure and temporal relationship to the procedure. No formal statistical hypotheses will be tested. Only device- or procedure-related AEs will be collected in this post-market study.

    Measured: 6 months post-implant

  2. Change from Baseline OSA at 6 Months

    AHI at the 6-month follow-up will be compared to the AHI at baseline in both the ACTIVE and DELAY groups.

    Measured: 6 months post-implant

  3. Change from Baseline Breathing Indices at 6 Months

    Sleep disordered breathing indices at the 6-month follow-up will be compared to the breathing indices at baseline.

    Measured: 6 months post-implant

  4. Change from Baseline Quality of Life Questionnaires (QoL)

    Quality of Life (QoL) questionnaires at the 6-month visit will be compared to the QoL questionnaires at baseline.

    Measured: 6 months post-implant

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Inspire® Upper Airway Stimulation (UAS) System in people with Obstructive Sleep Apnea, run by Inspire Medical Systems, Inc. at 4 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 4 inclusion and 7 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: stopped early, as of the sponsor's last update on 11 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Germany, Belgium. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Study halted due to low recruitment. Reimbursement changes require a larger study with additional centers and therefore, a new study planned as replacement.). Results are not available in the source record.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline OSA at 3 Months (time frame: 3 months post-implant). 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 Aug 2016.
