NCT ID NCT06296550

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 Results may not be published yet.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 is testing whether adding a continuous glucose monitor (CGM) to a text-message diabetes education program helps people with type 2 diabetes better manage their blood sugar. About 140 participants who do not use insulin will receive daily texts about diabetes care and a CGM to track glucose levels in real time. The main goal is to see if this combination lowers A1c levels over six months.

What this could mean

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

Active substance
continuous glucose monitor (Dexcom G7) and text-based diabetes education
What this could lead to
If successful, this could show that combining real-time glucose monitoring with text support helps people with type 2 diabetes better manage their blood sugar without insulin.
What could go wrong
This is a small, early-stage study with only 140 participants and no blinding, so results may not apply to everyone. The intervention requires active participation and a compatible cellphone.

Participants

About 140 people

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Apr 2027

An estimate. End dates often move.
