NCT ID NCT02724566

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 Results may not be published yet.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 early study tested whether a protein called apelin can improve how the body uses insulin in people with type 2 diabetes. Nine volunteers received both apelin and a placebo infusion to compare effects. The goal was to see if apelin increases the amount of sugar the body can process, which could lead to better blood sugar control.

What this could mean

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

Active substance
apelin (a synthetic version of a natural protein, given as an infusion)
What this could lead to
If it works, this could point toward a new way to improve insulin sensitivity in type 2 diabetes.
What could go wrong
This is a very small, early-phase trial with only 9 participants. It is designed to test safety and basic effects, not to prove a treatment works.
