About this study

Approximately 48 million people in the United States have hearing loss or hearing difficulties in noisy environments. Concha Inc. is working on introducing a wireless air-conduction hearing aid to the market, featuring a self-fitting feature. Self-fitting hearing aids have emerged in recent years as a potentially viable option towards addressing unmet hearing health care needs for millions of individuals who suffer from mild-to-moderate hearing loss. The purpose of this study is to evaluate the efficiency and reliability of the self-fitting strategy developed by Concha Inc.

Read the detailed description

The clinical study will be carried out using a within-subject, randomized, crossover study design in which all study participants will complete two different study arm conditions (clinician-fitting and self-fitting). Objective, subjective, and behavioral responses will be gathered from a variety of hearing-related surveys and tests, and will be analyzed quantitatively to evaluate the efficiency and reliability of the self-fitting procedure developed by Concha Inc.

The Quick Speech-in-Noise (QuickSIN) Test will be used as the primary effectiveness endpoint. QuickSIN is a quick and easy test that can measure an individual's ability to understand speech in noise. The secondary effectiveness endpoint will be assessed by using the Abbreviated Profile of Hearing Aid Benefit (APHAB). The APHAB was designed to evaluate the effect of hearing impairment or benefit in daily life APHAB and has long been considered the gold standard for patient-reported perceived benefit.

For this clinical study to be deemed successful, the self-fitting method needs to yield outcomes (namely QuickSIN and APHAB scores) which are non-inferior to the clinician-fitting method. Non-inferiority refers to an outcome where the new intervention (in our case, self-fitting) is not significantly worse than the established intervention (in our case, clinician-fitting), while also accounting for a clinically-significant margin.

Study groups in NCT06167161
Study groupRoleWhat they receive
Screening, intake and first fit (either clinician-fitting or self-fitting )Active comparatorThis clinical trial compares two methods of fitting individuals who suffer from hearing loss with a hearing aid device. Subjects will wear the hearing aid after receiving the clinician-fitting (device fitted by a clinician according to standard clinical best practice procedures) and self-fitting (device fitted by the user directly without assistance from a clinician following an automated assessment and fitting process) for two weeks each, totaling to approximately 1 month of wear throughout the trial. During the first visit, all individuals will go through intake procedures and a basic audiologic evaluation. After this is completed, individuals will be randomly assigned into one of two arms of the study. Individuals in the first visit of the study, will receive either the clinician-fitting or the self-fitting method for the first two weeks, then will switch to the experimental self-fitting or the clinician-fitting method for the last half. The order of the fitting will be randomized.
Receives: Device: Hearing aid
Second fit (either clinician-fitting or self-fitting )Sham comparatorIn the second visit of the study, individuals who randomly received the conventional clinician-fitting for the first two weeks (first period) will switch to the experimental self-fitting for the remainder of the study (second period). Conversely, individuals who received the experimental self-fitting method for the first two weeks (first period) will switch to the clinician-fitting method for the last two weeks (second period). The same within-subject crossover design will be followed in both clinical sites and for all individuals who were enrolled in the study.

What is being measured

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

  1. QuickSIN

    A standardized measure of speech communication in noise, Quick Speech-in-Noise. (QuickSIN). Scores are clinically reported as SNR loss, the difference (in dB) between a listener's performance and that of normal-hearing adult controls. The SNR loss score is an indication of an individual's overall degree of difficulty understanding speech in noise. The greater the SNR loss the poorer the listener's ability is to hear in noise. The QuickSIN test manual provides adjective descriptors corresponding to the SNR loss score where an SNR loss score of 0 to 2 dB is normal, 2 to 7 dB is mild, 7 to 15 dB is moderate, and greater than 15 dB is defined as severe.

    Measured: 15 days

Secondary outcomes (1)
  1. APHAB

    Self-report scale according to the Abbreviated Profile of Hearing Aid Benefit (APHAB). The APHAB is a self-report scale consisting of 24 Likert scale questions and is composed of four subscales including Ease of Communication (EC), Reverberation (RV), Background Noise (BN), and Aversiveness (AV). This outcome measure assesses residual activity limitations for hearing impaired individuals and it ranges from Never (1%) to Always (99%). APHAB scores represent how frequently clients experience performance problems and therefore a high APHAB score reflects a worse outcome.

    Measured: 15 days

Model description
This investigation will incorporate a within-subject, randomized, crossover study design in which all study participants will complete two different study arm conditions. During the first visit, subjects will be randomly allocated to study arm A (clinician-fitting) or study arm B (self-fitting). Following the initial two-week take-home field trial, the research participants will be assigned to the opposite study arm such that a complete two-sequence crossover design (AB/BA design) will be followed. The same within-subject crossover design will be followed in both clinical sites and for all individuals who will be enrolled in the study.

Questions about this trial

What is this clinical trial studying?

A study testing Hearing aid in people with Hearing Loss, run by Concha Inc. at 2 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 7 inclusion and 10 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 18 Dec 2023. 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 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

QuickSIN (time frame: 15 days). 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 18 Dec 2023.
