Exubera vs Lispro in a Lantus-based Regimen for Improved Glycemic Control in Type 2 Diabetes

The current trial will examine the efficacy and safety of Exubera administered as a mealtime insulin compared to lispro, when added to an existing regimen of basal insulin glargine + or = Oral Agents (OAs). Dose titrations will be provided which should allow a large proportion of subjects to reach target glycosylated hemoglobin (A1C) levels.

The scoring of responses to each item is analyzed so that a higher item score indicates more satisfaction.
