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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests a new method called image-guided cochlear implant programming (IGCIP) that uses CT scans to map the exact position of electrodes inside the ear. By deactivating poorly placed electrodes, the approach aims to customize implant settings for better hearing. Adults aged 18 to 90 who already have a cochlear implant may participate. The study compares standard programming with this image-guided approach to see if it improves speech understanding.

What this could mean

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

Active substance
Image-guided cochlear implant programming (IGCIP), a method using post-operative CT scans to customize implant electrode settings
What this could lead to
If successful, this approach could improve hearing outcomes for cochlear implant users, potentially allowing better speech understanding in noisy environments.
What could go wrong
The trial is early and may not show significant benefit over standard programming. Risks are minimal but include those associated with CT scans, such as radiation exposure.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 150 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2015

Expected to finish

May 2027

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 90 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 to 90 years that have undergone diagnostic testing for sensorineural hearing loss and have received a cochlear implant with asymptotic improvement in performance with SOC programming will be considered eligible for the study. Exclusion Criteria: * Age \< 18 years or \> 90 years * Non-English speaking (because our audiological speech testing battery is validated for English speakers) * Pregnancy which is a contraindication for elective CT scanning and surgery
