Mylan's insulin glargine
DrugAll patients will be shifted from their current mealtime insulin to insulin lispro at the start of the run-in period, and will continue on this for the complete trial. During the 6 week run-in period the doses of Lantus® and insulin lispro will be titrated (if required) to ensure diabetes control. After the run-in period, patients will be randomized to receive either Mylan's insulin glargine (in place of Lantus®), or to continue on Lantus®. During the period from 12 to 24 weeks dose titration will be kept to a minimum.
