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 Results may not be published yet.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

Summary

This study looked at whether improving blood sugar control can restore a protein called apoC1, which helps reduce bad cholesterol. Researchers compared 160 type-1 diabetes patients with poor blood sugar control to 80 healthy controls. They took blood samples to measure how well apoC1 was working. The goal was to see if better blood sugar levels could improve cholesterol management.

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 point toward new ways to manage cholesterol in type-1 diabetes by focusing on blood sugar control.
What could go wrong
This is an observational study, not a treatment trial. It only measures correlations, so it cannot prove that improving blood sugar directly fixes cholesterol problems.

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.
