Diabetes, Diabetes Mellitus, Type 2
Conditions
Brief summary
This trial is conducted in Asia. The purpose of the trial is to investigate the efficacy and safety of liraglutide in combination with insulin therapy compared to insulin alone in Japanese subjects with type 2 diabetes mellitus. Subjects will remain on their pre-trial insulin therapy.
Interventions
Liraglutide administered subcutaneously (s.c., under the skin) for 36 weeks combined with insulin therapy.
Liraglutide placebo administered subcutaneously (s.c., under the skin) for 36 weeks combined with insulin therapy.
All subjects will continue their pre-trial insulin therapy (basal, premixed or basal-bolus regimen) during the trial. Insulin dose is fixed for the first 16 weeks and for the subsequent 20 weeks, insulin dose is individually adjusted.

| Lira + Insulin Liraglutide was administered subcutaneously (s.c., under the skin) once daily (OD) for 36 weeks combined with insulin therapy. The starting dose of the liraglutide was 0.3 mg (50 μL)/day; dose was escalated to 0.6 mg (100 μL)/day and 0.9 mg (150 μL)/day during first 2 weeks; dose was maintained at 0.9 mg (150 μL)/day for subsequent 34 weeks.
All subjects continued their pre-trial insulin therapy (basal: once daily \[OD\] or twice daily \[BID\], premixed: OD or BID or basal-bolus regimen \[basal: OD or BID and bolus: three times a day\]).
