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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at whether a predefined plan to pause and restart blood thinners (factor Xa inhibitors) around minor procedures—like dental work, cataract surgery, or routine endoscopy—can reduce bleeding in people with atrial fibrillation. It follows 2,500 adults who take rivaroxaban, apixaban, or edoxaban and are scheduled for a minor bleeding-risk procedure. The goal is to see if this approach lowers major bleeding within 30 days without increasing the chance of stroke or blood clots.

What this could mean

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

Active substance
Factor Xa inhibitor (rivaroxaban, apixaban, or edoxaban) with a protocol for pausing and resuming around minor procedures
What this could lead to
If successful, this could provide a safer, standardized way to manage blood thinners around minor surgeries, reducing bleeding complications while protecting against strokes.
What could go wrong
This is an observational study, so it cannot prove cause and effect. Results may vary by patient and procedure, and there is always a risk of bleeding or clotting despite the protocol.
