Patients with type 1 diabetes mellitus and many patients with type 2 diabetes mellitus require daily use of insulin for the maintenance of normal glucose homeostasis. At present, insulin can be delivered only by injection. The availability of noninjectable routes of insulin administration may eliminate a barrier to effective therapy and improve the quality of life for many patients with diabetes.

Exclusion criteria
Exclusion criteria: - Patients who are investigator site personnel directly affiliated with the study, or are immediate family of investigator site personnel directly affiliated with the study. - Patients who are employed by Lilly or Alkermes (that is, employees, temporary contract workers, or designees responsible for the conduct of the study). Immediate family of Lilly employees may participate in Lilly-sponsored clinical trials, but are not permitted to participate at a Lilly facility. - Patients who have received treatment within the last 30 days with a drug that has not received regulatory approval for any indication at the time of study entry - Patients who have previously completed or withdrawn from this study or any study investigating any form of inhaled insulin. - Patients who are taking a thiazolidinedione (TZD) dose greater than rosiglitazone 4 mg daily or pioglitazone 30 mg daily.

| Main Objective: The primary objective of this study is to test the hypothesis that the glycemic control achieved with preprandial HIIP is noninferior to that achieved with injectable insulin, as measured by mean change from baseline to endpoint in hemoglobin A1c (HbA1c) after approximately 12 months, in patients with diabetes and chronic obstructive pulmonary disease (COPD) or asthma. A noninferiority margin of 0.4% for HbA1c will be used.;Secondary Objective: 1) To compare effects of preprandial HIIP and injectable insulin after approximately 12 months, in patients with diabetes and COPD and/or asthma on: - FEV1, FVC, total lung capacity, DLCO before inhalation of bronchodilator - change in FEV1, FVC 30, and DLCO 30 minutes after inhalation of bronchodilator - safety assessed by insulin antibody titers, adverse events, episodes of hypoglycemia - safety using serial chest x-rays - safety assessed by St. George’s Respiratory Questionnaire - safety assessed by Six-Minute Walk Test with Borg CR10 Scale - 8-point self blood glucose monitoring profiles - insulin dose requirements 2) To explore proportion of patients that require conversion to basal/bolus therapy to achieve an HbA1c <7.5% after at least six months of treatment. 3) To assess insulin inhaler reliability in patients randomized to treatment with HIIP 4) To explore impact of HIIP on peak flow and peak flow variability in the subgroup of patients with asthma;Primary end point(s): The primary outcomes of this study will be the efficacy measure HbA1c change from baseline to endpoint and the assessment of HIIP effects on important safety parameters. | — |
