Single Dose Clamp Study To Compare Concentration/Time Profile And Metabolic Activity Profile Of 2 New Formulations Of Insulin Glargine With Lantus

Primary Objective:

To compare the pharmacokinetic (PK) characteristics of single doses of insulin glargine given as U200 and U500 with those of a single dose (SD) of Lantus® U100 in a euglycemic clamp setting in subjects with type 1 diabetes.

Secondary Objectives:

To compare the metabolic activity characteristics of single doses of insulin glargine given as U200 and U500 with those of a single dose of Lantus® U100 in a euglycemic clamp setting in subjects with type 1 diabetes.

To assess the safety and tolerability of single doses of U200, U500 and Lantus® U100 in subjects with type 1 diabetes.

Total study duration for each subject is between 3.5 and 12 weeks.

Two overnight stays at the unit in each of 3 treatment periods.

* Known hypersensitivity to insulin glargine or excipients of the study drug.
* Any history or presence of deep leg vein thrombosis or a frequent appearance of deep leg vein thrombosis in first degree relatives (parents, siblings or children).
