Eksperimentell: Sitagliptin
Participants treated with sitagliptin 100 mg, once daily, for 24 weeks.
All participants will be under treatment with a stable dose of insulin with or without metformin for ≥10 weeks before and throughout the study.
All participants will receive placebo during the Placebo Run-in period.

Andre navn:
Participants can be on on pre-mixed (mixture of rapid- and long-acting insulin) or intermediate- or long-acting insulin at a dose of at least 12 U/day.
At randomization, participants will be stratified according to their use of metformin (on or not on).
All participants receiving metformin will be required to be on a daily dose of metformin at least 1500 mg per day.
