About this study

To re-assess the benefits of CT3 series CGM and the risks of skin abnormalities, hypoglycaemia, hyperglycaemia so as to improve CT3 series CGM continuously.

Treatment and study plan

CT3 Series Continuous Glucose Monitoring System:

Device

The CT3 Series CGM System is a real-time, continuous glucose monitoring device indicated for the management of diabetes in adults (age≥18 years). Interpretation of the CT3 Series CGM System results should be based on the glucose trends and several sequential readings over time. The CT3 Series CGM System also aids in the detection of episodes of hyperglycaemia and hypoglycaemia. It is intended for single-patient use. It is intended to replace fingerstick blood glucose testing for diabetes treatment decisions unless otherwise indicated

Primary outcomes

This PMCF study (Version V2.0) uses a strong evaluation plan, with methods and timing carefully matched to the study's rules. It includes 72 patients

Time frame: 14 days

The Continuous Glucose Monitoring (CGM) is done for 14 days for each person. During this time, glucose readings are collected every three minutes in real-time Self-Monitoring of Blood Glucose (SMBG) involves using fingerstick tests to check glucose levels.

Important measurements-like Time in Range (TIR), Time Above Range (TAR), Time Below Range (TBR), and error grid analysis-are taken at specific times, including at the beginning and on certain follow-up days.

These timings help collect key data to check how well the device works in the short term and how it affects glucose control over the full monitoring period.
