Auditory Brainstem Implantation in Young Children
United States5 participantsStarted 2012-09
Plain-language summary
To purpose of this feasibility study is to demonstrate the safety and efficacy of the Nucleus 24 Multichannel Auditory Brainstem Implant (ABI, Cochlear Corp, Sydney, AUS) in children without the diagnosis of neurofibromatosis type II (NFII) that have either experienced failed cochlear implantation (CI) or have been unable to receive a CI secondary to cochlear or cochlear nerve disorders. These conditions can include: developmental or acquired cochlear nerve deficiency (CND), cochlear aplasia (Michel), post-meningitic cochlear ossification or cochlear malformation.
This study proposes to implant up to 10 young children (\<5 yrs. of age) with the Nucleus 24 Multichannel ABI (Sydney, AUS) in an attempt to demonstrate safety of the surgical procedure, tolerance of device stimulation, and the potential for auditory benefit beyond that experienced with their CI. This study will provide the preliminary experience for a larger scale clinical trial.
Aim 1: Demonstrate the safety of ABI surgery in children. Aim 2: Demonstrate the development of sound awareness and improved speech understanding among children implanted with the ABI when compared to their baseline skills. Aim 3: Demonstrate the development of oral language skills following the use of the ABI that were not evident prior to its use.

Inclusion Criteria:
* Pre-linguistic hearing loss (birth-5 yrs.; age at ABI 18 months-5yrs) with both:
* MRI +/- CT evidence of one of the following: Cochlear nerve deficiency, Cochlear aplasia or severe hypoplasia, Severe inner ear malformation, Post-meningitis ossification
* When a cochlea is present or patent, lack of significant benefit from CI despite consistent use (\>6 mo.)
* Post-linguistic hearing loss (\<18 yrs. of age) with both:
* Loss or lack of benefit from appropriate CI without the possibility for revision or contralateral implantation. Examples might include: Post-meningitis ossification, Bilateral temporal bone fractures with cochlear nerve avulsion, Failed revision CI without benefit
* Previously developed open set speech perception and auditory-oral language skills
* No medical contraindications
* Willing to receive the appropriate meningitis vaccinations
* No or limited cognitive/developmental delays which would be expected to interfere with the child's ability to cooperate in testing and/or programming of the device, in developing speech and oral language, or which would make an implant and subsequent emphasis on aural/oral communication not in the child's best interest
* Strong family support including language proficiency of the parent(s) in the child's primary mode of communication as well as written and spoken English.
* Reasonable expectations from parents including a thorough understanding:
* of potential benefits and limitations of ABI
* of …
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
