The study will assess glycemic variability and optimized glycemic control in T2DM patients treated with a DPP-4 inhibitor as add-on therapy to metformin.

Condition Intervention Phase
Type 2 Diabetes Mellitus
Drug: Vildagliptin
Drug: Sitagliptin
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: 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

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Glycemic variability assessed by MAGE (Mean Amplitude of Glycemic Excursion) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Glycemic control assessed through CSGM [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Glycemic control assessed by A1C, FPG, PPG and the mean of 6 points self-monitoring of blood glucose (SMBG) at baseline and after 8 weeks [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
  • Unrecognized hypoglycemic periods recorded by CSGM, frequency and duration [ Time Frame: 8 weeks ] [ Designated as safety issue: Yes ]
