NCT00424437
First received: January 17, 2007
Last updated: February 9, 2007

  Purpose

To determine, in subjects with Type 1 Diabetes Mellitus:

  1. Whether glycemic control can be achieved at least as effectively with an insulin regimen involving pre-meal inhaled insulin plus a single bedtime Ultralente injection as with a conventional subcutaneous insulin regimen involving 2-3 mixed Regular/NPH insulin injections per day.
  2. The toleration and safety of inhaled insulin therapy and its effects after 6 months, if any, on measures of pulmonary function.

Primary Outcome Measures:
  • Primary outcome is 24 week change in baseline in HbA1c

Secondary Outcome Measures:
  • The secondary endpoints include the following efficacy assessments:
  • Incidence of hypoglycemia
  • Proportion of subjects with acceptable glycemic control (e.g., HbA1c<8%)
  • Change from baseline in fasting lipid profile
  • Change from baseline in fasting plasma glucose level
  • Change from baseline in meal glucose response (2-hour postprandial increment in plasma glucose)
  • Dose of insulin (total dose of injected sustained-duration insulin, and total dose of inhaled or injected Regular insulin during the study).
  • Change from baseline in body weight
  • Change from baseline in 24-hour home glucose profile (based on the area under the glucose profile curve calculated by the trapezoid rule with special weights assigned to the pre-breakfast and bedtime assessments).
  • Patient satisfaction and preference.
