Brief summary
This is a prospective within-subjects repeated-measures study that will enroll 17 users 13 years or older implanted with a HiResolution Bionic Ear System.
Detailed description
The overall goal of this clinical study is to demonstrate the safety and efficacy of the remote fitting option. Hearing outcomes are expected to be similar whether a study subject's sound processor is programmed in the traditional method in the audiologist's office or whether programming is performed via remote fitting. Therefore, the study described herein uses a non-inferiority design to determine whether sentence recognition in quiet is no worse with remote fitting than in an in-office setting.
Interventions
Processors will be programmed using remote fitting application.
Processors will be programmed using standard Target CI application.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Speech Performance in Quiet After Chronic Use (EO Only) | 2-3 weeks after fitting | The primary efficacy endpoint is the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post investigational remote fitting (visit 3) as compared to the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post control in-office fitting (visit 2). Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome. |
| Speech Performance in Quiet - Chronic Use (Includes Overall - Both Groups) | Test performed 2-3 weeks after fitting | The primary efficacy endpoint is the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post investigational remote fitting (visit 3) as compared to the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post control in-office fitting (visit 2). Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome. |

Recruitment details
Investigators recruited study subjects from their clinical practices. The first patient visit occurred on 08/18/21 and last patient visit occurred on 05/23/22. Of the 19 enrolled, 2 were deemed ineligible to continue after visit 1 and 17 subjects were assigned to a study; 12 subjects were enrolled in the EO group and 5 subjects were enrolled in the ARH sub-group based on the results of their audiometric testing. All 17 subjects completed the study, with no withdrawals or losses to follow up.
Pre-assignment details
Per protocol, a subject is considered enrolled upon giving written informed consent. After undergoing the ICF process, subjects completed a hearing test. Depending on the outcome of that test, eligible subjects were enrolled for aidable residual hearing (ARH) fitting with an acoustic earhook. Unilaterally implanted subjects not meeting ARH fitting criteria were enrolled for electric only (EO) fitting. Bilaterally implanted subjects meeting ARH criteria only in one ear were screen failed.
Participants by arm
| Arm | Count |
|---|---|
| Electric Only Any subject that did not meet the ARH fitting criteria was enrolled in the EO fitting group. The EO group were fit with the investigational processor and an Advanced Bionics T-mic for the duration of the study. All subjects (both EO and ARH) underwent the same testing procedures after appropriately fitted. | 13 |
| Aidable Residual Hearing (ARH) Includes subjects that met all general inclusion criteria and hearing inclusion criteria specific for ARH group.
* Residual low frequency hearing sensitivity (pure tone average of \< 70 dB HL for 125, 250, and 500 Hz) and a severe-to-profound high-frequency sensorineural hearing loss (pure tone average of ≥ 70 dB HL for 1,000, 2,000, 3000, 4,000, and 8,000 Hz) in the implanted ear for unilaterally implanted subjects and in both ears for bilaterally implanted subjects

Outcome results
Speech Performance in Quiet After Chronic Use (EO Only)
The primary efficacy endpoint is the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post investigational remote fitting (visit 3) as compared to the chronic AzBio sentence recognition scores in quiet captured two-to-three weeks post control in-office fitting (visit 2). Scores are determined on a scale of 0% to 100% words correct with higher scores indicating a better outcome.
