Effectiveness & Tolerability of Novel, Initial Triple Combination Therapy vs Conventional Therapy in Type 2 Diabetes
Effectiveness and Tolerability of Novel, Initial Triple Combination Therapy With Xigduo (Dapagliflozin Plus Metformin) and Saxagliptin vs. Conventional Stepwise add-on Therapy in Drug-naïve Patients With Type 2 Diabetes

Detailed Description
ADA/EASD guideline recommends sequential treatment approach starting with metformin, and adding other classes of anti-diabetic medications if target HbA1c is not achieved. However, several clinical studies clearly showed that initial dual or triple combination therapy was more favorable in terms of glycemic control.
A DPP-4 inhibitor saxagliptin increases serum level of GLP-1, and potentiates its action of increasing glucose-dependent insulin secretion and lowering glucagon secretion. A SGLT-2 inhibitor dapagliflozin lowers hyperglycemia via blocking SGLT-2 to increase glucosuria, that is, in an insulin-independent manner. Therefore, the mechanism of action of these drugs are complimentary to that of metformin, and all of these have a low risk of hypoglycemia and weight gain.
