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 Results may not be published yet.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 completed study looked at how blood pressure changes over 12 weeks in 1,729 adults with hypertension who used the Aktiia 24/7 optical blood pressure monitor. The device is a wristband that measures blood pressure continuously without a cuff. Researchers also asked participants which monitoring method they preferred: the Aktiia bracelet, a home blood pressure monitor, or a 24-hour ambulatory monitor. The goal was to gather information, not to test a treatment.

What this could mean

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

Active substance
Aktiia 24/7 optical blood pressure monitoring (OBPM) device
What this could lead to
If successful, this study could show that continuous optical blood pressure monitoring is a practical and preferred way to track hypertension at home.
What could go wrong
This is an observational study, not a treatment trial. It cannot prove that using the device improves health outcomes, and results may not apply to all people with high blood pressure.
