Conditions
Brief summary
This trial is conducted in South Africa, Europe and North America. The aim of this trial is to compare efficacy and safety of NN1250 (insulin degludec (IDeg)) with insulin glargine (IGlar), as add-on to subject's ongoing treatment with metformin and/or dipeptyl peptidase 4 (DPP-4) inhibitors, in patients with type 2 diabetes being treated with oral anti-diabetic drugs (OADs) qualifying for intensified treatment.
Interventions
Injected subcutaneously (under the skin) once daily. Dose was individually adjusted.

Outcome results
Change in Glycosylated Haemoglobin (HbA1c)
Change from baseline in HbA1c after 26 weeks of treatment
Time frame: Week 0, Week 26
Population: Full analysis set (FAS) includes all randomised subjects and missing data was imputed using last observation carried forward (LOCF). 2 subjects were withdrawn prior to exposure to the study drug in the IDeg arm as they were randomised in error and 1 subject in the IGlar arm.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| IDeg 200 U/mL OD | Change in Glycosylated Haemoglobin (HbA1c) | -1.30 percentage of glycosylated haemoglobin | Standard Deviation 1.04 |
| IGlar OD | Change in Glycosylated Haemoglobin (HbA1c) | -1.32 percentage of glycosylated haemoglobin | Standard Deviation 0.98 |
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 last observation carried forward (LOCF). For 3 subjects baseline values were missing.
| Arm | Measure | Value (MEAN) | Dispersion |
|---|---|---|---|
| IDeg 200 U/mL OD | Change in Fasting Plasma Glucose (FPG) | -3.70 mmol/L | Standard Deviation 3.06 |
| IGlar OD | Change in Fasting Plasma Glucose (FPG) | -3.38 mmol/L | Standard Deviation 2.96 |
