Further study details as provided by Diabetes Care Center:

Primary Outcome Measures:
  • Determine the mean value for the slop between the variables of total daily dose versus total basal dose. [ Time Frame: Two weeks ]

Secondary Outcome Measures:
  • Determine the slope between the other variables: weight, total daily dose, total basal dose, insulin correction carbohydrate rate, correction factor [ Time Frame: Two weeks ]

Estimated Enrollment: 50
Study Start Date: January 2010
Estimated Study Completion Date: October 2010
Estimated Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Lispro Insulin and glargine insulin
    Continuous glucose sensor will be inserted. Subject will be on an isocaloric diet and CGM downloaded daily. Insulin basal and bolus will be adjusted based upon treatment goals until goals reached
Detailed Description:
Subjects with stable type 1 diabetes mellitus on multiple daily insulin injections including basal and bolus will be selected in order to determine the correct insulin dosing formulas. Subjects will be placed on continuous glucose sensor (CGMS) and an isocaloric diet. Subjects will have the CGMS downloaded daily and the insulin doses adjusted if necessary. Subject will do four SMBGs daily to calibrate CGMS and on last day a 7-point SMBG. subjects will be on lispro and glargine insulin. Basal insulin will be once a day.
