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 Results may not be published yet.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

Summary

This study tests a device called the Calibreye System, a small implant placed in the eye to help drain fluid and lower pressure in people with open-angle glaucoma. Researchers will check if it is safe and works well over 12 months in 60 adults. The goal is to see if the device can reduce eye pressure and possibly cut down on the number of glaucoma medications needed.

What this could mean

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

Active substance
Calibreye System (glaucoma implant device)
What this could lead to
If successful, this device could offer a new way to lower eye pressure and reduce the need for daily eye drops in people with open-angle glaucoma.
What could go wrong
This is an early feasibility study with only 60 people, so results may not apply to everyone. The device may not lower pressure enough or could cause side effects like infection or implant failure.
