Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 100 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2022-08-17
• Study Completion Date: 2024-04-30

Brief Summary

The goal of this clinical trial is to learn about the benefits of using aa Continuous Glucose Monitoring (CGM) system in patients with diabetes following discharge from the hospital. The main question it aims to answer is:

• If the use of CGM with alarms is safe and effective for managing low and/or high blood sugars when compared with performing finger sticks several times per day

Participants will wear one or two FreeStyle Libre CGM sensors for 12-14 days three times over a 12-week (3 month) period. This means that they will have the one to two sensors inserted under their skin. They will be asked to come to the study site four times and complete two phone calls with research staff over the 12-week period.

Researchers will compare the LibreView CGM group to the Standard of Care group to see if the use of continuous glucose monitoring (CGM) reduces risk of low blood sugar in patients with type 2 diabetes (T2D) after hospital discharge when compared with the current standard method.

Detailed Description

The purpose of this study is to look at the benefits of using Continuous Glucose Monitoring (CGM) system for patients with diabetes following discharge from the hospital. CGM devices measure blood sugar every few minutes using a sensor inserted under the skin.

In this study, we will compare the CGM method to the current usual (standard-of-care) method, which involves taking blood samples by fingerstick before meals and at bedtime. The CGM system recognizes low and high blood sugars throughout the day and night. The CGM system used in this study also has an alarm feature that alerts the user if blood sugar levels are too high or too low. In this study we will test if the use of CGM with alarms is safe and effective for managing low and/or high blood sugars when compared with performing finger sticks several times per day, which some diabetes patients find painful and burdensome.

In this study, 50% of participants will use the CGM method and 50% will use the fingerstick method to measure and control their glucose. The researchers will compare the two groups to answer the question if the use of continuous glucose monitoring (CGM) reduces risk of low blood sugar in patients with type 2 diabetes (T2D) after hospital discharge when compared with the current standard method.

Study Groups

FreeStyle Libre 2

Subjects randomized to Group 1: FreeStyle Libre 2 will wear two FreeStyle Libre CGM sensors for 12-14 days three times over a 12-week (3 month) period. They will have two sensors inserted under their skin:

FreeStyle Libre 2 sensor with display on, meaning they will be able to see their blood sugar values on the mobile application or a reader.

FreeStyle Libre Pro sensor is used without mobile application or reader. This sensor is place as a backup in case the information is missing from the Libre 2 sensor.

Group Type: ACTIVE_COMPARATOR

FreeStyle Libre 2 CGM

Intervention Type: DEVICE

FreeStyle Libre 2 CGM is FDA-approved and will be used according to FDA-approved labeling

FreeStyle Libre Pro blinded CGM

Intervention Type: DEVICE

FreeStyle Libre Pro blinded CGM is FDA-approved and will be used according to FDA-approved labeling

Point of Care (POC) Self-Monitoring of Blood Glucose (SMBG) testing

Subjects randomized to Group 2: Point of Care (POC) Self-Monitoring of Blood Glucose (SMBG) testing will wear one FreeStyle Libre Pro CGM sensor without using the mobile application or reader (blinded). These subjects will have the one sensor inserted under their skin but you will not see sugar values on the CGM. Subjects will wear the CGM for 12-14 days three times over a 12-week (3 month) period but will not use the CGM to monitor and control their blood sugar. Instead, they will monitor their sugar values by the standard method of fingerstick before each meal and at bedtime.
