Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the study is to assess the effect of FGM on glycemic control compared with SMBG using a randomised controlled study design in adults with type 2 diabetes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Flash glucose monitoring (FGM) is a newly introduced Glucose Monitoring system. The aim of the study is to assess the effect of FGM on glycemic control compared with standard blood glucose monitoring (SMBG) using a randomised controlled study design in adults with type 2 diabetes. Subjects will use unmasked FGM once a month or SMBG to monitor glucose level for 3 months. Patients in the SMBG group will wear masked FGM to collect glycaemic variability data for comparison to the intervention group of the study. The primary outcome, HbA1c, will be cpmpared at baseline and 3 month. Glucose control parameters provided by unmasked and masked FGM will be compared in the two groups, including mean blood glucose (MBG), coefficient of variation (CV), area under the curve (AUC), Time in Range(TIR), etc.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FGM group

Diabetic patients will use FreeStyle Libre Flash Glucose Monitoring (FGM) system(unmasked) to monitor glucose level once a month for 3 months.

Group Type EXPERIMENTAL

Freestyle Libre Flash Glucose Monitoring

Intervention Type DEVICE

Freestyle Libre Flash Glucose Monitoring will be used in diabetic patients once a month for therr months to monitor glucose level. Patients could scan the sensor to get the glucose level at any time as they want. They could alter thier diet and exercise according to the glucose levels. Patients will be required to keep track of food and exercise during wearing FGM sensor. Physicians would adjust patients' medication according their glucose profile provided by FGM, A1c, and diet and exercise every month.

SMBG group

Diabetic patients will use Standard Blood Glucose Monitoring (SMBG) to monitor glucose level for 3 months. A 14-day masked wear of FreeStyle Libre H Flash Glucose Monitoring system is included for these subjects once a month, to collect glycaemic variability data for comparison to the intervention group of the study.
