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 This study
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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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 will test whether combining continuous glucose monitor (CGM) data with information from a smartwatch and a phone app (like meals and activity) can better predict blood sugar levels in people with type 2 diabetes. Thirty-six adults will wear a CGM and smartwatch and log their meals and exercise for several weeks. The goal is to build a model that gives real-time glucose predictions, but this study only collects data—it does not provide any treatment or recommendations.

What this could mean

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

What this could lead to
If successful, this could lead to a smartphone app that predicts blood sugar changes in real time, helping people with type 2 diabetes manage their condition more easily.
What could go wrong
This is a small, early-stage study (36 people) that only collects data—it does not test a treatment. The model may not work well for everyone, and results may not apply to people outside this specific clinic.

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Participants will be selected from the Johns Hopkins Medicine adult clinical population. The study population will include adults with type 2 diabetes who receive diabetes care through Johns Hopkins Medicine, including primary care and endocrinology clinics. Participants will be recruited from patients whose routine diabetes care includes use of continuous glucose monitoring and who may be eligible to contribute glucose, wearable, app-based behavioral, and electronic medical record data for development and validation of glucose prediction models.

Ages
