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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study examined whether certain genes are linked to a severe form of diabetic eye disease called proliferative diabetic retinopathy (PDR). Researchers analyzed DNA from 302 people with type 2 diabetes, some with PDR and some without. The goal was to find genetic markers that might help predict who is at higher risk for vision-threatening eye disease.

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 certain genes are found to be linked to severe diabetic eye disease, this could help identify people at higher risk earlier.
What could go wrong
This is an observational study, not a treatment trial. It only looks for genetic links, so it cannot directly lead to a new therapy. The results may not apply to all populations.

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

302 people

The number who actually took part.

Started

Oct 2013

Finished

Jan 2021

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 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

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

Inclusion Criteria: * type 2 diabetic patients * patient with proliferative diabetic retinopathy (for arm 1) * patient with non proliferative diabetic retinopathy (for arm 2) * patient older than 18 years * patient consenting to participate to the study * patient enrolled in the national healthcare insurance program
