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

Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.

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 Mayo Clinic study tested a special smartwatch that uses light sensors to measure blood glucose, blood pressure, and heart signals. The goal was to see if the watch could give accurate readings compared to standard methods like finger-stick tests and blood pressure cuffs. The study included 87 diabetic patients who were already having regular blood sugar checks. However, the study was terminated early, so the final results are not available.

What this could mean

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

Active substance
LIFELEAF Smartwatch (wearable device using light sensors)
What this could lead to
If successful, this could lead to a convenient, non-invasive way for people with diabetes to check blood sugar and blood pressure using just a smartwatch.
What could go wrong
This was a small, early-stage study that was terminated, so results may be limited. The technology may not be as accurate as standard blood tests or cuffs.
