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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tests whether dapagliflozin, a drug typically used for diabetes, can prevent atrial fibrillation from coming back after a procedure called cardioversion (an electric shock to restore normal heart rhythm). About 1600 adults with AF will take either dapagliflozin or no extra drug for up to 56 days. Researchers will track heart rhythm using a handheld device to see if the drug reduces recurrence.

What this could mean

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

Active substance
dapagliflozin (a diabetes drug that lowers blood sugar and may help heart rhythm)
What this could lead to
If it works, this could offer a new, short-term treatment to prevent atrial fibrillation from coming back after cardioversion.
What could go wrong
This is a phase 3 trial, but it's still early to know if dapagliflozin truly helps AF. The drug may not reduce recurrence, and side effects like dehydration or kidney issues are possible.
