What participants receive

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

  • Hypoglossal Nerve Stimulation (HGNS) System (Apnex Medical )Device

    The HGNS System in an investigational device that includes three implantable components: a neurostimulator, a stimulation lead, and a respiration sensing lead. The HGNS System is designed to activate the muscles in the upper airway to help keep the airway open during sleep. The HGNS System is intended for the treatment of moderate to severe OSA in individuals that have failed or do not tolerate positive airway pressure (PAP) therapy.

What is being measured

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

  1. Reduction in OSA Severity

    The proportion of subjects that experience clinically meaningful improvement in AH1 (reduction >50% and AHI <20) and ODI 4% (reduction >= 25% or ODI 4% <5)from Baseline to 6 Months will be significantly greater in the Treatment Group compared to the Control Group

    Measured: from Baseline to 6 Months

  2. Long-term Reduction in OSA Severity

    The proportion of subjects in the Treatment Group that experience clinically relevant improvement in AHI (reduction >50% and AHI <20) and ODI 4% (reduction >=25% or ODI 4% <5 at 12 months compared to Baseline.

    Measured: 12 months

  3. Safety Analysis

    Description of all adverse events

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hypoglossal Nerve Stimulation (HGNS) System (Apnex Medical ) in people with Obstructive Sleep Apnea, run by Apnex Medical, Inc. at 14 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 0 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 15 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 14 sites in United States, Australia. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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. 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?

Reduction in OSA Severity (time frame: from Baseline to 6 Months). The study lists 3 primary outcomes in all. 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 15 Apr 2015.
