Comparison of the Effect on the Glucose Infusion Rates Between Inhaled Technosphere Insulin and a Subcutaneous Injection of Regular Human Insulin

Effect of Different Doses of Inhaled Technosphere Insulin on Glucose Infusion Rates During Euglycemic Clamps in Comparison to a Subcutaneous Injection of Regular Human Insulin

A prospective, single center, open randomized, six way crossover study comparing the dose response effect of four different doses of Technosphere Insulin after pulmonary function delivery in comparison to s.c. injection of two different doses of regular human insulin.
