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 Results may not be published yet.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.

Summary

This study tests a small, battery-powered device called ClotChek™ that measures how fast a patient's blood clots using a fresh drop of blood. Researchers want to see if it can tell the difference between people on common blood thinners (rivaroxaban or apixaban) and those not on any. About 150 adults aged 18 to 80 will take part, and the goal is to make monitoring blood thinners quicker and easier at the bedside.

What this could mean

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

Active substance
Perosphere ClotChek™ coagulometer (device)
What this could lead to
If successful, this device could give doctors a fast, bedside way to check blood-thinner levels, helping to reduce bleeding or clotting risks.
What could go wrong
This is an early performance study with only 150 participants, so the device may not be accurate enough for all patients or settings.
