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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 looks at whether exercise training, the drug liraglutide, or both together can improve blood flow to the heart and muscles and help the body use insulin better in adults with metabolic syndrome. About 80 participants will be randomly assigned to one of four groups: control, exercise only, liraglutide only, or exercise plus liraglutide. They will be monitored for 24 weeks to measure changes in blood vessel function and insulin sensitivity.

What this could mean

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

Active substance
Liraglutide (a GLP-1 receptor agonist drug) and supervised exercise training
What this could lead to
If successful, this could show that combining exercise with liraglutide improves heart and muscle blood flow and insulin sensitivity better than either alone, pointing to a more effective management strategy for metabolic syndrome.
What could go wrong
This is a relatively small, early-phase trial (80 participants) focused on short-term changes in blood flow and insulin action, not long-term health outcomes. Results may not apply to all people with metabolic syndrome, and liraglutide can cause side effects like nausea or vomiting.
