What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 uses PET scans to watch brain activity while people with cochlear implants try to understand speech in background noise. Researchers want to pinpoint which brain regions help make sense of sound in challenging listening situations. The study includes 120 cochlear implant users and 30 people with normal hearing, all adults aged 18 to 99.

What this could mean

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

What this could lead to
If successful, this could reveal which brain areas help cochlear implant users understand speech in noise, guiding future improvements in implant design or therapy.
What could go wrong
This is an observational imaging study, not a treatment trial. It may not lead directly to any new therapy or device, and results may not apply to all implant users.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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

Nov 2024

Expected to finish

Mar 2028

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 99 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.

Cochlear Implant subjects (enrollment is planned at N=120) - Inclusion criteria: 1. Between 18 and 99 years of age. 2. Have a cochlear implant activated for more than one year. 3. Eligible for research under the Iowa Cochlear Implant Project VIII. 4. Ability to understand and willingness to sign a written informed consent document. 5. Severe hearing loss after age 16. Normal Hearing subjects (enrollment is planned at N=30) - Inclusion criteria: 1. Between 18 and 99 years of age. 2. Have age typical hearing. 3. Eligible for research under the Iowa Cochlear Implant Project VIII. 4. Ability to understand and willingness to sign a written informed consent document. Exclusion criteria (all groups): 1. Medical history includes seizure disorder, head injury, neurologic, metabolic, cardiovascular disease, or previous cerebrovascular event (unless approved by PI). 2. Female self-reporting pregnancy. A urine pregnancy test will be performed prior to injection of the radiopharmaceutical. 3. Currently taking medications which may affect cerebral blood flow (e.g., papaverine, ginkgo biloba, acetazolamide). 4. Uncontrolled intercurrent illness that would limit compliance with study requirements per investigator.
