Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- Adults aged 18 or older (Group A), or children aged 5 to 17 years and 11 months (Group B)
- The ear to be implanted has severe hearing loss in a specific range, with a pure-tone average above 80 dB HL at key frequencies, and very poor word recognition even with hearing aids (a score of 5% or less on a standard speech test)
- The other ear has normal or near-normal hearing (average of 30 dB HL or better at key frequencies)
- People who have previously tried a conventional treatment for single-sided hearing loss — such as a hearing aid, bone-conduction device, or CROS hearing aid — or who are willing to try one of these options for at least two weeks before joining
- English is the person's primary spoken language
- Willing and able to provide written consent to participate (for children, a parent or guardian would be involved in this process)
Who may not be able to join:
- People whose inner ear (cochlea) has abnormalities such as bone growth, an unusual cochlear nerve, or other structural issues that may prevent the implant from being fully inserted
- People who have already had a cochlear implant
- People whose hearing loss originates from the nerve or brain, including a condition called auditory neuropathy
- People who have had profound hearing loss in the ear to be implanted for more than 10 years (based on self-report)
- People with an active or ongoing middle-ear infection, or a type of hearing loss caused by a physical blockage rather than nerve damage, in either ear
- People whose overall health or psychological condition means surgery is not considered appropriate, as judged by the trial investigator
- People whose expectations about what the implant can achieve are considered unrealistic, as judged by the trial investigator
- People with signs of or concerns about cognitive or developmental difficulties
- People who are unwilling or unable to follow the requirements of the trial, as judged by the trial investigator
- Staff members at the trial site who are directly involved in this study, or their immediate family members (spouse, parent, child, or sibling)
- Employees of Cochlear (the company running the trial) or employees of research organisations contracted to work on this trial
- Women who are pregnant or breastfeeding
- People who are currently taking part in, or have taken part in within the last 30 days, another clinical trial involving an experimental drug or medical device
