Brief Summary

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.

Detailed Description

The main objective of the study is to evaluate the effectiveness of COVER PATCH CAPTEUR PROTECT solutions for glucose sensors, in terms of improving glycemic control in patients with poorly controlled diabetes and suboptimal sensor wear time, compared to management without the COVER PATCH.

This is an interventional, prospective, randomized, controlled, multicenter clinical trial comparing the HbA1c levels of patients using COVER PATCH CAPTEUR PROTECT solutions for glucose sensors versus standard care.

The use of COVER PATCH CAPTEUR PROTECT solutions could result in a 0.3 percentage point improvement in HbA1c in diabetic patients initially having an HbA1c ≥ 8% and a glycemic sensor wear time of < 70%.

The device under study is the COVER PATCH solution by CAPTEUR PROTECT. This patch is a Class I, non-sterile, single-use device. COVER patches are intended for use in association with continuous glucose monitoring devices for patients living with diabetes.

COVER patches are compatible with a wide range of continuous glucose monitoring (CGM) devices available on the market. Several versions of the patches are available depending on the type of sensor (Freestyle 2 or 3, Dexcom G6/One or G7/One+, Guardian Sensor 4 or Simplera).

In this study, participants use their regular continuous glucose monitor (CGM), either with or without the adhesive patch being evaluated. Upon enrollment, retrospective data from the past 4 months are collected for analysis.

At the start of the study, participants complete the following questionnaires:

• Diabetes Treatment Satisfaction Questionnaire - status version (DTSQs)
• Diabetes Distress Scale (DDS) The adult, adolescent, or parent version is be provided depending on the participant's age.

Throughout the study, participants use an electronic tool (ePRO) to record each sensor change and indicate the reason for the replacement. Participants can also report any adverse events and device deficiency.

After 4 months, a follow-up visit takes place. Data from the previous 4 months are collected for analysis. Participants complete the same questionnaires again, as well as additional ones:

• Diabetes Treatment Satisfaction Questionnaire - change version (DTSQc)
• Physical activity questionnaire
• Satisfaction questionnaire regarding cover patch use The adult, adolescent, or parent version is be provided depending on the participant's age.

The study duration per patient is 4 months.

Study Groups

COVER PATCH

Participants use their usual continuous glucose monitoring (CGM) sensor with the COVER PATCH adhesive patch during the study.

Group Type: EXPERIMENTAL

Use of COVER patchs for continuous glucose monitoring sensor

Intervention Type: DEVICE

The intervention consists of wearing a patch over the continuous glucose monitoring (CGM) sensor typically used by the participant.

The COVER patch is compatible with a wide range of CGM devices on the market, including Freestyle 2 or 3, Dexcom G6/One or G7/One+, and Guardian Sensor 4 or Simplera.

At each sensor change, the participant is required to apply a new COVER PATCH over the CGM sensor. This is done throughout the entire duration of their participation in the study, which lasts for 4 months.

Standard of care

Participants use their usual continuous glucose monitoring (CGM) sensor without the COVER PATCH adhesive patch during the study (standard of care)

Group Type: NO_INTERVENTION

No interventions assigned to this group
