What is being measured

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

  1. Number and Proportion of Subjects Experiencing Device Related Adverse Events

    Adverse events will be collected and reported throughout the duration of the study.

    Measured: Up to three (3 months) post activation

  2. Percentage Change in AZ Bio Sentence Score in Noise

    Percent improvement in AZ Bio sentence in noise scores will be compared from baseline to 3 months post activation.

    Measured: Baseline and 3 months post activation

Secondary outcomes (4)
  1. Percentage Change in CNC Word Score

    Percent improvement in CNC word scores will be compared from baseline to 3 months post activation.

    Measured: Baseline and 3 months post activation

  2. Number of Subjects With Stable or Better Soundfield Thresholds

    The number of subjects with stable or better aided soundfield thresholds at 3 months post activation compared to baseline unaided soundfield thresholds

    Measured: Baseline and 3 months post activation

  3. Number of Subjects With Better QuickSIN Signal-to-noise-ratio Performance

    The number of subjects with similar or better performance on the QuickSIN (Speech In Noise) task in the implanted ear compared to baseline performance

    Measured: Baseline and 3 months post activation

  4. Number of Subjects With Stable Unaided Bone Conduction Thresholds

    The number of subjects with stable bone conduction thresholds at the device activation interval compared to pre-operative bone conduction thresholds.

    Measured: Baseline and 2 weeks post surgery

Questions about this trial

What is this clinical trial studying?

A study testing BONEBRIDGE in people with Hearing Loss, Conductive and Hearing Loss, Mixed, run by Med-El Corporation at 3 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 13 inclusion and 3 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 30 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 3 sites in United States, Canada. 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?

Yes. Results are posted in the registry (first posted 30 May 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number and Proportion of Subjects Experiencing Device Related Adverse Events (time frame: Up to three (3 months) post activation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03859648, which also lists 6 linked publications.

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 30 May 2024.
