Study of the Efficacy and Safety of Inhaled Technosphere Insulin in Patients With Type 2 Diabetes
Efficacy and Safety of Inhaled Technosphere Insulin Compared to Technosphere Placebo in Patients With Type 2 Diabetes Mellitus Following Diabetes Education

Primary objective to evaluate the effect of a 12-week treatment period with prandial administration of Technosphere Insulin on glucose control in subjects with T2 DM. Secondary objective is to Evaluate the safety and tolerability of a 12-week treatment period of Technosphere Insulin and Technosphere Placebo.
