To compare the efficacy of a new formulation of insulin glargine and Lantus in terms of change of HbA1c from baseline to endpoint (scheduled at month 6 [week 26]) in patients with type 2 diabetes mellitus.
Secondary Objectives:
- To compare a new formulation of insulin glargine and Lantus in terms of change in fasting plasma glucose, pre-injection plasma glucose, 8-point self-measured plasma glucose profile.
- To compare a new formulation of insulin glargine and Lantus in terms of occurrence of hypoglycemia
Insulin glargine is produced by recombinant DNA technology using a non-pathogenic laboratory strain of Escherichia coli (K12) as the production organism. It is an analogue of human insulin made by replacing the asparagine residue at position A21 of the A-chain with glycine and adding two arginines to the C-terminus (positions B31 and 32) of the B-chain. The resulting protein is soluble at pH 4 and forms microprecipitates at physiological pH 7.4. Small amounts of insulin glargine are slowly released from microprecipitates giving the drug a long duration of action (up to 24 hours) and no pronounced peak concentration.
