This prospective, non-randomized, non-controlled, interventional study will determine whether the Roche automated bolus caclulator (ABC) reduces post-meal hyperglycemia better than the competitor's ABC without causing significant hypoglycemia.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • To compare the difference between the self-monitoring blood glucose (SMBG) value achieved at 6 hours after meals with induced post-prandial hyperglycemia and the mean target value of 110 mg/dL. Target post-prandial range is 80-140 mg/dL. [ Time Frame: 6 hours after meal ]

Secondary Outcome Measures:
  • To compare the absolute difference between the SMBG value and the target value between the calculators [ Time Frame: 6 hours after meal ]
  • To compare theto compare the relative difference (multiplied by 100) between the SMBG value and the target value between the calculators [ Time Frame: 6 hours after meal ]
  • To compare the absolute relative difference (RAD, multiplied by 100) between the SMBG value and the target value between the calculators [ Time Frame: 6 hours after meal ]
