About

This study will compare the effect of Dapagliflozin added to Metformin vs Metformin alone on blood sugar fluctuations of adults with a recent diagnosis of Type 2 Diabetes (T2D). The duration of the protocol will be 12 weeks. Continuous glucose monitoring will be measured before and at the end of the intervention. The questions this protocol will answer include:

• Is there a difference in blood sugar fluctuations when Dapagliflozin is added to Metformin compared with Metformin alone in adults with type 2 Diabetes?
• Does Dapagliflozin added to Metformin improve blood glucose control in patients with type 2 Diabetes?

Full description

This is an open-label randomized clinical trial aimed to compare the effect of Dapagliflozin added to Metformin vs Metformin alone on glycemic variability of adults with a recent diagnosis of type 2 Diabetes. The central hypothesis is that the addition of Dapagliflozin will lead to a statistically significant improvement in GV parameters compared to Metformin alone. A total of 88 adults aged 18-70 years with T2DM and HbA1c between 7.5% and 12% while on a stable dose of Metformin 2000 mg/day will be enrolled. Participants will be randomized in a 1:1 ratio to one of two treatment arms for a duration of 12 weeks. The primary objective is to compare the change from baseline to end-of-treatment in key glycemic variability indices derived from continuous glucose monitoring (CGM) (Mean Amplitude Glucose Excursions -MAGE, Time in Range), changes in HbA1c, fasting blood glucose, lipid profile, BMI, blood pressure, among others.
