Interventional Clinical Trial Evaluating COVER PATCH CAPTEUR PROTECT Support Solutions for Continuous Glucose Monitoring Sensors in Patients With Diabetes

Recruiting now · Not applicable

Conditions studied: Diabetes

In brief

The aim of this clinical trial is to evaluate whether the COVER PATCH adhesive patch can improve the adhesion of continuous glucose monitors (CGMs). CGMs provide continuous blood sugar readings throughout the day and night, providing valuable data to help individuals manage their diabetes more efficiently. Many people face difficulties in keeping their CGM sensor in place. Factors such as sweat, physical activity, heat, skin creams, and swimming can cause the sensor to fall off prematurely, interrupting glucose monitoring and making it harder to maintain stable blood sugar levels. It has been shown that wearing a CGM sensor for at least 70% of the time is linked to better blood sugar control, measured by lower glycated hemoglobin (HbA1c). HbA1c reflects the average blood sugar over the past 3 months. A lower HbA1c level is associated with better diabetes management. Currently, CGM sensors are designed for one-time use and need to be replaced every 7 to 15 days. However, when sensors fall off prematurely, they need to be replaced more frequently, leading to higher costs for patients. This can exceed what is covered by insurance. Some patients use non-approved solutions, like extra adhesive tapes, to keep their sensors in place, but these methods may not be effective. This clinical trial aims to answer the following questions: * Does the adhesive patch help keep the CGM sensor in place for the full recommended duration? * Does better sensor adhesion lead to improved blood sugar control and lower HbA1c? * Does the patch help reduce the frequency of premature sensor replacements? To take part in this study, participants must be at least 6 years old and have type 1 or type 2 diabetes. Participants continue using their usual CGM during the study and are randomly assigned to either use the adhesive patch (COVER PATCH) or not. Participants and/or their parents (depending on the participant's age) complete questionnaires at the start of the study, and again at the end of the study at 4 months. Throughout the 4-month period, they also use an electronic tool (ePRO) to record each CGM sensor change and the reason for replacement. This study may help improve how well glucose sensors stay in place, reduce the need to change them too often, and make it easier to manage blood sugar. It also aims to fulfill a medical need that is currently not adequately covered.
