Clinical Trial Summary

As we get older, our hearing deteriorates and an age-related hearing loss can develop. Having a hearing loss can make it more difficult for people to understand conversations. Hearing aids can help in these situations, but difficulties often remain in more challenging situations, for example, when a conversation is being held in a group or when background noise is present. These difficulties are often not only related to the hearing loss but also to how these sounds are processed in the brain. Auditory rehabilitation is believed to help persons with a hearing impairment train their listening and communication skills. Auditory rehabilitation includes sensory management to enhance auditory function; knowledge and skills to improve the outcome; perceptual training and counselling. For this reason, the ALICE app was developed. The ALICE app contains monitoring tests, listening training exercises and counselling for persons with a hearing impairment.

In the current study, the ALICE app will be evaluated by persons with a hearing impairment. The experimental group will use the ALICE app in addition to the standard of care (hearing aid or cochlear implant) while the control group will receive the standard of care. Listening and communication skills will be evaluated pre and post training by a speech perception test in noise and questionnaires.

Description:

This study is set-up as a pre-market clinical investigation of a non-CE marked medical device. The main goal of the study is to measure the efficacy of the ALICE app (Assistant for Listening and Communication Enhancement), a newly developed software application that will function as an added service in the aural rehabilitation of persons with HI, by providing remote monitoring, training and follow-up.

We will evaluate the efficacy and the clinical validity of the ALICE-app by means of a randomized controlled trial (RCT) with two arms. The first arm of the RCT will be carried out with 180 experienced hearing aid and/or cochlear implant users. The second arm of the RCT will be carried out with 120 first time hearing aid users. The participants will be divided in two groups: one group receiving the standard of care (control group), and another group receiving the standard of care supplemented with the ALICE-app.

All participants in the first arm will be assessed two times, at the beginning of the study and after 8 weeks of training (or without for the control group). The participants in the second arm will be assessed three times, at the beginning of the study, during the trial period with hearing aids and at the end of their trial period. The trial period with hearing aids takes on average 4-6 weeks. For the assessment we will use standardized clinical measures. These measures include a speech perception test in noise and validated questionnaires. The efficacy of ALICE will be determined in a within-subject design, i.e., baseline session outcomes will be compared to the final session outcomes of the randomized control trial, with a repeated measures ANOVA (α = 0.05).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Speech in noise intelligibility	LIST (Leuven intelligibility sentences test) sentences presented in speech-weighted noise. Participants are required to repeat sentences in noise. The Leuven Intelligibility Sentences Test (LIST, (van Wieringen & Wouters, 2008)) was specifically designed for speech perception in noise assessment in CI users. The test has a high test-retest reliability and a steep slope making it very sensitive to small improvements in performance. An improvement of 2dB results in a clinically relevant improvement in speech discrimination in noise. Therefore, the primary endpoint to validate the ALICE app will be an improvement of 2dB on speech discrimination in noise.	During the first appointment before using the ALICE app

The Brugge-Leuven-Utrecht list (BLU, ((Bosman, Woutes & Damman), 1994)) is a validated speech test during which Dutch words are provided in quiet or in noise. Each list contains 10 2-sylable words.

Secondary	COSI (Client Oriented Scale of Improvement)	The COSI questionnaire is a validated clinical tool that can assist in measuring the impact of hearing aid fitting on a person's life and the benefit that is obtained after intervention (Dillon et al., 1997). Administering the COSI questionnaire is also part of the RIZIV application to receive a refund for hearing aids. The COSI questionnaire allows the audiologist to measure improvements in listening situations important for their client. Before fitting the hearing aids, together with their client, they list their client's needs/goals. After hearing aids have been fitted and the client has had time to experience the hearing aids, they evaluate the progression/satisfaction in these situations together with their client.

Secondary	CAS (Communication and Acceptance Scale)	The CAS is a validated scale that consist of 18 items (Öberg et al., 2021). The CAS scale is a reliable instrument that can be used to measure the effect of a rehabilitation programme. Each question is scored on a 5-point Likert scale (completely agree to completely disagree). It was developed to detect clinical changes in "communication strategies and the emotional consequences, knowledge and acceptance of hearing loss". This questionnaire has been translated from Swedish to Dutch (and back translated to ensure correct translation).	During the first appointment before using the ALICE app
