What this trial studies

This clinical trial aims to evaluate the effectiveness of Continuous Glucose Monitoring (CGM) using the FreeStyle Libre device compared to Self-Monitoring of Blood Glucose (SMBG) in patients with type 2 diabetes. The study will involve 126 participants who have an elevated HbA1c between 7.0 - 10.0% and are not using prandial insulin. Participants will receive personalized education on lifestyle modifications and will be monitored over a 12-week period to assess changes in their glycemic control. The study is randomized and open-label, with participants assigned to either the CGM or SMBG group.

Who should consider this trial

Good fit: Ideal candidates are adults aged 19-80 diagnosed with uncontrolled type 2 diabetes mellitus and an HbA1c level between 7.0 - 10.0%.

Not a fit: Patients with other types of diabetes, those using prandial insulin, or individuals with severe skin conditions that prevent the use of CGM devices may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve glycemic control and lifestyle management for patients with type 2 diabetes.

How similar studies have performed: Other studies have shown promising results using CGM for diabetes management, indicating that this approach has potential based on previous findings.
