Diabetes, Diabetes Mellitus, Type 2
Conditions
Brief summary
This trial will be conducted in Africa, Asia, North America and South America. The aim of this clinical trial is to compare NN1250 (insulin degludec) with sitagliptin, as add-on to subject's own current oral antidiabetic (OAD) treatment, in subjects with type 2 diabetes inadequately controlled with 1-2 OADs (metformin, sulphonylurea, glinides or pioglitazone).
Interventions
Injected under the skin once daily for 26 weeks. The doses will be individually adjusted.
Sitagliptin tablets administered orally once a day at the same time every day for 26 weeks

Outcome results
Change in Glycosylated Haemoglobin (HbA1c)
Change from baseline in HbA1c after 26 weeks of treatment
Time frame: Week 0, Week 26
Population: The full analysis set (FAS) included all randomised subjects and missing data was imputed using last observation carried forward (LOCF). A site was closed, hence 11 randomised subjects (4 subjects with IDeg; 7 subjects with DPP-IV group/arm) were excluded from the FAS.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| IDeg OD | Change in Glycosylated Haemoglobin (HbA1c) | -1.56 percentage of glycosylated haemoglobin | Standard Deviation 1.09 |
| DPP-IV Inhibitor | Change in Glycosylated Haemoglobin (HbA1c) | -1.22 percentage of glycosylated haemoglobin | Standard Deviation 1.16 |
Change in Fasting Plasma Glucose (FPG)
Change from baseline in FPG after 26 weeks of treatment
Time frame: Week 0, Week 26
Population: The FAS included all randomised subjects and missing data was imputed using LOCF. One site was closed, hence 11 randomised subjects (4 in IDeg and 7 in DPP-IV group/arm) were excluded from the FAS. Fasting plasma glucose values were missing for another 8 subjects, hence did not contribute to the analysis.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| IDeg OD | Change in Fasting Plasma Glucose (FPG) | -3.22 mmol/L | Standard Deviation 3.17 |
| DPP-IV Inhibitor | Change in Fasting Plasma Glucose (FPG) | -1.39 mmol/L | Standard Deviation 3.11 |
