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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 aims to better understand which brain areas handle tasks like memory, language, and perception. 120 patients with brain tumors will perform short cognitive tests before and during awake surgery. By comparing test results, researchers hope to create a map of brain regions involved in these functions, which could help guide future surgeries.

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 create a detailed map of brain regions linked to memory, language, and perception, improving surgical precision.
What could go wrong
This is an early observational study with no treatment being tested. Results may not apply to all patients or lead to direct clinical changes.

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 120 people

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

Expected to start

Nov 2025

An estimate. Start dates often move.

Expected to finish

Nov 2030

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 75 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: * Patients with a brain tumor * Aged 18 to 75 years * Signed informed consent * Vision that is corrected or adequate for the purposes of an experiment with visual stimuli * Hearing that is corrected or adequate for the purposes of an experiment with auditory stimuli * No known oculomotor disorder * Person affiliated with or benefiting from a social security scheme. * Free, informed, and written consent signed by the participant and the investigator (no later than the day of inclusion and before any examination required by the research) Exclusion Criteria: * Participants under protected status: guardianship, legal safeguard proceedings, or whose consent to participate in the experiment could be due to a severely altered psychological state, as determined by the medical team responsible for the surgery. * History of neurological disease affecting the central nervous system (Parkinson's, Alzheimer's, history of stroke or cerebral infarction) * Pregnant and/or breastfeeding women.
