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 Results may not be published yet.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

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.

Summary

This study tests whether a special scoring tool (the Lyon-VTE score) can better prevent dangerous blood clots in pregnant women at high risk compared to standard care. About 600 pregnant women with a personal history of blood clots or a clotting disorder will be randomly assigned to either score-guided prevention or usual recommendations. The goal is to see if personalized care is safer, more effective, and more cost-efficient.

What this could mean

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

Active substance
Lyon-VTE score (risk assessment tool)
What this could lead to
If successful, this could provide a validated, personalized approach to prevent dangerous blood clots during pregnancy, reducing unnecessary treatment and costs.
What could go wrong
This is a relatively early-stage trial (phase not specified) and the score has only been tested in retrospective and small prospective studies. It may not prove more effective or cost-saving than current care.
