NCT ID NCT06437639

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed Phase 4 trial tested the drug Mexidol in 80 people with advanced primary open-angle glaucoma. The goal was to see if the drug could improve the function of mitochondria in cells and protect the optic nerve. Participants were randomly assigned to receive Mexidol or standard care, and researchers measured changes in cell energy levels and vision over time.

What this could mean

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

Active substance
Mexidol (ethylmethylhydroxypyridine succinate)
What this could lead to
If it works, this could point toward a way to protect the optic nerve in glaucoma patients, potentially slowing vision loss.
What could go wrong
This is a small, completed Phase 4 trial with only 80 participants, so results may not apply to everyone. The main focus is on cell-level changes, not direct vision improvement, and the drug may not work as hoped.
