About this study

Official title: To Evaluate the Long-term Safety and Efficacy of the Esteem® Hearing Implant in Subjects Suffering From Moderate to Severe Hearing Loss

The purpose of this study is to evaluate the long-term safety and efficacy of the Esteem® Hearing Implant in subjects suffering from moderate to severe hearing loss.

Read the detailed description

The Post Approval Study is an extension of the pivotal clinical trial, which was designed as a prospective, multi-center, non-randomized, clinical trial to evaluate the safety and efficacy of the Esteem® System. For this trial the subject acts as his or her own control.

This trial has been designed to meet the United States' regulatory requirements.

The subjects included in this study include the 57 subjects implanted under the original Investigational Device Exemption (IDE) study and the five (5) subjects implanted under the continued access expansion approved by the FDA. Of these 62 subjects, all but one (explant) were available for continued follow-up. These subjects were re-consented for the 5 year Post Approval Study. No new subjects were enrolled and implanted in this study. The goal was to monitor a minimum of 45 subjects through their five (5) year follow-up. Ultimately, 51 subjects completed the study.

The following questions are to be answered:

  • Is the Esteem effective through 5 year follow-up?
  • Is the Esteem safe through 5 year follow-up?

What participants receive

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

  • The Esteem Hearing ImplantDevice

    The Esteem® Hearing Implant is designed to improve hearing in subjects suffering from moderate to severe hearing loss that is sensorineural in origin. The Esteem® has been approved by FDA for the US market under Pre-Market Approval P090018 and this study fulfills the requirement for one of the Post Approval Studies.

What is being measured

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

  1. Change From Baseline (Pre-implant Aided Condition) at Year 5 in Speech Reception Threshold (SRT)

    ENDPOINT #1: SRT at baseline minus SRT at Year 5. Positive difference (i.e. lower value of SRT with the Esteem) indicates better outcome.

    Measured: Baseline through Year 5 of Follow Up

  2. Change From Baseline (Pre-implant Aided Condition) at Year 5 in Word Recognition Score (WRS) at 50 dB HL

    ENDPOINT #2: WRS at Year 5 minus WRS at baseline. Positive difference (in % correct) indicates better outcome.

    Measured: Baseline through Year 5 of Follow Up

  3. Incidence of Serious Adverse Device Events (SADEs) and Device Failures and Replacements at Each Follow-up.

    ENDPOINT #3: The analysis of the incidence of SADEs and device failures and replacements at each follow-up.

    Measured: SADEs, PAS phase through Year 5 of Follow Up

  4. Bone Conduction Stability

    ENDPOINT #5: Difference between Baseline and 5 Year Pure-Tone Average (PTA; average of 500, 1000, 2000 Hz thresholds); calculated as PTA at Year 5 minus PTA at baseline. Smaller magnitude dB difference indicates better outcome.

    Measured: Baseline through 5 Year Follow-Up

Secondary outcomes (1)
  1. Improvement in Quality of Life as Reflected by Abbreviated Profile of Hearing Aid Benefit (APHAB) Questionnaire

    APHAB results were obtained from baseline aided condition through Year 5 of follow up. The APHAB responses are in terms of percent of time an individual experiences problems, on a scale of 0-100%; lower scores indicate fewer problems.Compared scores with Esteem to scores in baseline aided condition, calculated as APHAB Global score at baseline minus APHAB Global score at Year 5, giving a "difference in benefit" score. The Global Score is the mean of the scores (% of problems) for Ease of Communication (EC), Reverberation (RV), and Background Noise (BN) subscales of the APHAB. A positive difference in benefit score indicates more benefit with Esteem.

    Measured: Baseline through Year 5 of Follow Up

Questions about this trial

What is this clinical trial studying?

An observational study of Hearing Loss, run by Envoy Medical Corporation at 5 sites in United States.

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 16 inclusion and 16 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: finished, as of the sponsor's last update on 4 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. 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 4 May 2016). 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?

Change From Baseline (Pre-implant Aided Condition) at Year 5 in Speech Reception Threshold (SRT) (time frame: Baseline through Year 5 of Follow Up). The study lists 4 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 4 May 2016.
