Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Primary purpose: TREATMENT

Brief summary: 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.


Eligibility criteria: Inclusion Criteria:

* Type 1 Diabetes for more than 1 year
* Stable insulin regimen of at least 2 injections per day

Exclusion Criteria:

Any smoking within the last 6 months. Smoking is not permitted at any time during this study.

* Subjects on insulin pump during 2 months prior to screening.
* Subjects with poorly-controlled asthma, clinically significant chronic obstructive pulmonary disease, or other significant respiratory disease.

Primary outcomes:
measure: Primary outcome is 24 week change in baseline in HbA1c
Secondary outcomes:
measure: The secondary endpoints include the following efficacy assessments:
measure: Incidence of hypoglycemia
measure: Proportion of subjects with acceptable glycemic control (e.g., HbA1c<8%)
measure: Change from baseline in fasting lipid profile
measure: Change from baseline in fasting plasma glucose level
measure: Change from baseline in meal glucose response (2-hour postprandial increment in plasma glucose)
measure: Dose of insulin (total dose of injected sustained-duration insulin, and total dose of inhaled or injected Regular insulin during the study).
measure: Change from baseline in body weight
measure: 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).
measure: Patient satisfaction and preference.
