World's largest Real-World CGM study aims to unlock diabetes management secrets
NCT ID NCT07681024
First seen Jul 02, 2026 · Last updated Jul 02, 2026
Summary
This global registry study follows 5,000 people with diabetes who use a Dexcom continuous glucose monitor (CGM). Researchers will track changes in HbA1c, a key measure of blood sugar control, over time. The goal is to understand how CGM use affects diabetes management in real-world settings across different countries and diabetes types.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dexcom continuous glucose monitor (CGM)
- What this could lead to
- If successful, this study could provide real-world evidence on how CGM use improves blood sugar control over time for different types of diabetes.
- What could go wrong
- This is an observational registry, not a controlled trial, so it cannot prove cause and effect. Results may vary by country and individual use patterns.

Inclusion Criteria: * "1. Meets Dexcom CGM System Indications for Use (IFU) per approved commercial labeling * 2\. Has at least one HbA1C (Hemoglobin a1c) measurement obtained within the three (3) months prior to the start date of first Dexcom CGM System use in the study (blinded or unblinded, whichever first). For participants with prior CGM experience (CGM non-naive), this HbA1c measurement must also be at least three (3) months after the end of any CGM usewithin three (3) months prior to the Dexcom CGM System use start date that is at least three (3) months after any prior CGM use * 3\. Participant is willing and able to use Dexcom CGM System according to approved product labeling * 4\. Participant is willing and able to complete applicable patient reported outcome assessments/ surveys * 5\. Participant is willing and able to comply with the Clinical Investigation Plan * 6\. Participant is willing and able to comply with provider requirements for at least one or more provider encounters after CGM initiation according to applicable clinical practice guidelines * 7\. Participant or the participant's legally authorized representative must provide written informed consent prior to any study-related data collection or be enrolled under an IRB/EC/REB approved waiver of consent" Exclusion Criteria: * "1.
