What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested whether changing the stimulation settings (called MAPs) in cochlear implants can improve how well adults with hearing loss understand speech, both in quiet and noisy environments. Twenty experienced cochlear implant users tried different low-power settings and electrode modes. The goal was to see if these adjustments could boost word recognition and speech understanding without sacrificing battery life.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Cochlear implant programming (MAP) with different stimulation parameters and electrode modes
What this could lead to
If successful, this could help fine-tune cochlear implant settings to improve speech perception for users.
What could go wrong
This is a small, completed study with only 20 participants, so results may not apply to all cochlear implant users. The changes tested are minor adjustments, not a breakthrough.

Inclusion Criteria: * Implanted with the CI600 Series (CI612, CI632, CI622, CI624), CI500 Series (CI512, CI513, CI532, CI522) or Freedom Series (CI24RE(CA), CI24RE(ST), CI24RE(CS), CI422) * At least three months after activation of the cochlear implant. * Eighteen years or older at the time of consent. * User of 900Hz ACE (Advanced Combination Encoder) strategy MAP. * Score of 20% or more for CNC words presented at 60dBSPL with CI alone in the test ear. * Fluent speaker in English. * Willing and able to provide written informed consent. Exclusion Criteria: * One or more electrodes turned off in the MAP used regularly. * Unable or unwilling to comply with the requirements of the clinical investigation as determined by the Investigator. * Investigator site personnel directly affiliated with this study and/or their immediate families; immediate family is defined as a spouse, parent, child, or sibling. * Cochlear employees or employees of Contract Research Organisations or contractors engaged by Cochlear for the purposes of this investigation. * Current participation, or participation in another interventional clinical study/trial in the past 30 days, involving an investigational drug or device (unless the other investigation was/is a Cochlear sponsored investigation and determined by the investigator or Sponsor to not impact this investigation).
