Glycemic Holter Study (Continuous Glucose Monitoring) - (OPTIMA)
Prospective, Randomized, Open-label Study With Blinded Endpoint (PROBE Design) to Compare the 72 hr Glycemic Profiles Obtained by Continuous Subcutaneous Glucose Monitoring (CSGM) in Type 2 Diabetic Patients at Baseline With Metformin Monotherapy and After an 8-week Period With the Addition of Either Vildagliptin or Sitagliptin in Patients Insufficiently Controlled by Metformin After at Least 3 Months of Monotherapy
